Pan Jiahao looked at the model frame with a smile on his face, and calmly calculated the time: 1 second, 2 seconds, 3 seconds, 4 seconds, 5 seconds, yes, it's now, it's now, the mud is about to spray out of the mold seams!

But to Pan Jiahao's disappointment, the five seconds he expected had passed, and there was not a trace of mud flowing out of the upper and lower seams of the model.

How is it possible? Could it be that I am too anxious, and the time for silent counting is a little faster?

Pan Jiahao slowed down and continued to time backwards in his heart: 6 seconds, 7 seconds, 7 seconds...... 20 seconds ...... 45 sec...... 60 seconds.

Pan Jiahao delayed the calculation for a full minute, but there was still not a trace of mud flowing out of the model frame.

At this time, everyone, including Wang Daojun and Tan Jinxuan, showed joy in their eyes.

They were all on site during the trial run this morning, and almost a few seconds after the grouting system started grouting the grouting system, there was mud flowing out of the upper and lower formwork interfaces of the model, and as time went by, all thirty models began to run the slurry, and the speed became faster and faster, and finally it could almost be sprayed out.

But now, a full 60 seconds have passed, and there is not even a single model of 30 models, not even a single slurry.

Of course, at this time, it cannot be said that Hao Shuang's method was successful, because the entire slurry process was 12 minutes, and only after the end of the 12 minutes of slurry process, none of the 30 models had slurry seeping out, which could show that Hao Shuang's method was successful.

But the running state of the production line in this minute can at least prove that Hao Shuang's method is indeed effective.

Everyone held their breath and stared at the model frame with full attention to see if the model could still maintain its current state over time, without running out of slurry or seeping slurry.

Sure enough, these thirty models did not disappoint them, and as time went on, there was still not a trace of mud seeping out.

Pan Jiahao was able to keep calm at first and keep silent counting in his heart, but when he silently counted to the third minute, his mood began to sink gradually, knowing that he was afraid that he would be slapped in the face by Hao Shuang, a mainland native bun college student, this time.

Because according to his more than seven years of equipment maintenance experience in Zhenghong Ceramics Company, if 99% of the slurry appears in the first three minutes of the grouting system, if the model does not run in the first three minutes, the probability of the follow-up model will be less than 1%.

But a one percent probability is also a probability, and before the entire grouting process is over, he still has hope of reversing it.

But to Pan Jiahao's disappointment, the twelve minutes were consumed, the grouting equipment completed the model slurry, the roaring motors stopped, and the exterior of the thirty models was all extremely dry, without the slightest phenomenon of running grout and seeping grout.

"It's successful, it's successful!" Tan Jinxuan and Wang Daojun glanced at each other, and they both saw the excitement in their eyes,

Hao Shuang smiled, scooped up the mud of half a hat from the ground, held it in front of Pan Jiahao with a dark face with both hands, and said softly: "Da Lang, your wish to cheat and drink has come true, please drink this bowl of medicine!"

There was a cheerful laughter at the scene: The surname Pan has always fed others medicine, but he didn't expect to be fed medicine by others today!

Looking at the ceramic mud that almost reached under his nose with half a hat, Pan Jiahao only felt his stomach churning.

He never imagined that the ceramic mud of the subjects he studied on a daily basis could become so abominable, especially when it was mixed with the ground oil, and the color had changed from the original gray-white to black lacquer, and it also gave off a pungent smell of waste engine oil, it was simply the best emetic in the world.

Fortunately, Pan Jiahao is also a person who has gone through strong winds and waves, otherwise it would not have been possible to be promoted from an ordinary technician to a technical assistant in a hierarchical Taihu enterprise.

"Hehe, Hao Shuang," he laughed, "Hao Shuang, I just made a joke for you, why did you take it seriously?"

Hao Shuang was not surprised that Wang Daojun stood up to help Pan Jiahao speak.

"Are you kidding me?" Hao Shuang also laughed.

"Yes, I was joking with you!" Seeing Hao Shuang stop, Pan Jiahao couldn't help but feel relieved, he shrugged his shoulders, "I didn't expect you to take it seriously, I really can't afford to joke at all!"

Saying that, he turned his head and smiled at Wang Daojun, and said: "Manager Wang, you mainlanders are too lacking in humor, I am really tired of dealing with you mainlanders......!

He hadn't finished his cheap words yet, but Hao Shuang directly splashed the half-hat mud over, and screamed "wow", his whole face turned into a clay sculpture, and his eyes, nose and mouth were stinky and sticky mud everywhere.

"Make a joke about your Malegobi!" Hao Shuang pointed and screamed at Pan Jiahao while hurriedly smearing mud and scolding loudly: "Lao Tzu gave you a bet of more than 20,000 marks, but you finally said that you were joking with Lao Tzu, really think Lao Tzu is a fool?"

After speaking, Hao Shuang threw the helmet "Bang Dang" low, and said to the stunned Tan Jinxuan: "Chairman Tan, the school motto of our Tianbei Mining Institute is 'serious, hardworking, realistic, and innovative', as a student of Tianbei Mining Institute, there is no such word as joke in my dictionary!"

Then he turned to Wang Daojun and said, "Manager Wang, you have also seen it, right? The slurry has nothing to do with the grouting cut-off valve, and it has nothing to do with my visit yesterday morning, but there is a problem with the parameters of the equipment itself." Now I have fulfilled my promise to help you solve the problem of equipment running out of pulp for free. Next time there is any problem with the equipment, you are welcome to come to me at any time, but I declare in advance that I will come to repair it in the next step, but I will charge the maintenance fee!"

Leaving this sentence, Hao Shuang walked away in a dashing manner, ignoring the shouts of Wang Daojun and Tan Jinxuan behind him.

Suddenly, I heard a sound of footsteps from behind, and when I turned my head to look, it was Xiao Pingxin chasing after me.

"Teacher Hao, Teacher Hao, please stay!" After seeing Hao Shuang's miraculous performance, Xiao Pingxin didn't dare to continue to call Hao Shuang "Little Hao" no matter what.

Other people's face can not be given, but he, an old subordinate in the previous life, still has to give face. After all, a large part of the reason why he was able to go so smoothly was the credit of this old subordinate. It's just that his old subordinate won't understand.

"Xiao Xiao, what's the matter?" Hao Shuang stopped and looked at Xiao Pingxin.

"Mr. Hao, I want to ask you, how did you see that it was not the problem with the shut-off valve of the grouting system?" Xiao Pingxin looked at Hao Shuang a little nervously, for fear that he would not be willing to explain to himself.

"Did Wang Daojun ask you to ask this question, or did you want to ask it yourself?" Hao Shuang looked at Xiao Pingxin with a smile.

Xiao Pingxin hesitated for a moment, and finally decided to tell the truth, "It was not only Manager Wang who asked me to ask, but also I wanted to know." ”

"Count yourself honest!" Hao Shuang reached out and patted Xiao Pingxin on the shoulder, and said to him: "Let's go, let's go find a small stall and talk while eating!"

Not far from the No. 1 Ceramics Factory, Hao Shuang ordered four side dishes: pig's head meat, cold skin belly, tofu rolls and peanuts, and asked for a few bottles of beer, chatting with Xiao Pingxin while eating.

If it is the slurry running caused by the failure of the hydraulic induction valve, not only the joints of the upper and lower mold bases of the model, but also the part of the cut-off valve assembly of the grouting system should also have a small amount of leakage. ”

"However, according to my observation at the site, the shut-off valve assembly of the grouting system is relatively dry, and there is no phenomenon of grout sticking out. Therefore, the fault of the hydraulic induction valve can be eliminated directly. Hao Shuang smiled and solved the mystery for Xiao Pingxin.

"I see!" Xiao Pingxin suddenly realized, and then asked another question: "If it is not the fault caused by the hydraulic induction valve, what is the reason for the serious slurry running of the model? Why is it that as long as the grouting time is extended and the compression spring of the mold base on the model is replaced, the problem of running slurry can be solved?"

"Well, I have to find the answer from the things you told me yesterday morning!" Hao Shuang said: "Didn't you tell me yesterday morning that Taihu Zhenghong Ceramics Company signed a technical service contract with Nelly Company. ”

According to the contract, Nelly Company will provide technical services to Zhenghong Ceramics Company, including the washing tank blank glaze formula. The technical archives of Zhenghong Ceramics Company also recorded that in February 1979, they sent a total of 12.5 tons of ceramic raw materials from Taihu to Nelly Company. ”

After testing these raw materials, it took more than two months to conduct industrial trials, and finally provided them with a green body and glaze formula suitable for the horizontal scrubber micro-pressure grouting line based on the raw materials provided by Zhenghong Ceramics. ”

And now Pan Jiahao also took the medicine according to the prescription after coming over, and directly took the blank glaze formula of Nelly Company to Caifeng Ceramics Company to use, without taking into account the different production conditions between Caifeng Ceramics Company and Zhenghong Ceramics Company, which eventually led to the problem of running out of pulp in the production line. ”

"Using Nelly's own recipe to produce it on Nelly's own production line, there will still be problems?" Xiao Pingxin asked in surprise.

"Yes!" Hao Shuang nodded and replied: "Tangerine is orange in Huainan, and orange is orange in Huaibei." The same blank glaze formula is no problem in Taihu Zhenghong Ceramics Company, but when it comes to Caifeng Ceramics Company, there will be problems. ”

"There are a couple of key factors in this. ”

"First, the production water used by Taihu Zhenghong Ceramics Company is surface water. Surface water is soft and has a relatively low degree of mineralization. ”

The production water used by Caifeng Ceramics Company is groundwater pumped from the factory's own well. Because this groundwater belongs to the shallow karst water at the southern foot of the Taihang Mountain, the salinity and hardness are very high. ”

Xiao Pingxin nodded, of course he knew about this situation. In fact, not only the self-provided well water of Caifeng Ceramics Company has high hardness, but also the groundwater in the entire Tianbei City area is so hard that as long as the kettle is not cleaned for a day, it will form a thick layer of scale.

"Therefore, even if Caifeng Ceramics Company adopts the same raw material formula as Zhenghong Ceramics Company, in the process of water injection and stirring, the magnesium sulfate ions and calcium sulfate ions contained in the water will react chemically with the raw materials in the high-level mud tank, resulting in changes in the viscosity and fluidity of the ceramic mud. ”

"This is the first factor that causes the run-out. ”

"The second factor is the production of raw materials. Hao Shuang continued to explain: "On the surface, the raw material formula used by Caifeng Ceramics Company is exactly the same as that used by Zhenghong Ceramics Company, but in fact there is still a big difference. ”

"Because the Taihu area itself lacks high-quality raw materials such as kaolin, clay, and high-alumina bauxite for the production of ceramics, Zhenghong Ceramics mainly relies on imports from neon countries and South Korea. ”

"Compared with the ceramic raw materials in the mainland, the standardization of raw materials such as kaolin, clay and high-alumina bauxite in neon country and south Korea is high, and Zhenghong Ceramics Company only needs to mix water and stir it into a ball mill for grinding, and then it can be put into the high-level mud tank on the production line for direct use. Only a very small amount of raw ore and plain waste needs to be refined. ”

The raw materials used by Caifeng Ceramics Company have a low degree of standardization and are basically raw ores, which need to be reprocessed by Caifeng Ceramics Company before they can be put into high-level mud tanks for use. ”

"Limited to the equipment and technical level of Caifeng Ceramics Company, the accuracy and stability of raw materials after reprocessing cannot be compared with Neon Country and South Korea. Therefore, even though the proportion of various raw materials is no different from the formula of Zhenghong Ceramics Company, it will eventually lead to an increase in the specific gravity and viscosity of the ceramic mud. ”

"Combined with the first reason, the final reaction on the production line is that the buoyancy on the ceramic mud inside the model is much greater than the total pressure of the compression spring of the upper mold base, which eventually leads to a serious phenomenon of running out of the pulp. ”

"So the first solution I gave was to extend the feeding time. As the slurry feed slows down, the floating pressure inside the model decreases. ”

"The second is to replace the compression spring in the upper mold base, and replace the Φ4 spring, which was originally designed with a maximum pressure of only 488.05N, with a Φ6 spring with a maximum pressure of 1273.04N. ”

"Reduce the floating pressure of the mud and increase the compression pressure of the mold base, so that the combination of the two, the problem of running the slurry will be solved!"

Xiao Pingxin suddenly realized, and his gaze turned into looking up at Hao Shuang.

I really didn't expect that the two simple solutions proposed by Hao Shuang at the production line site had such deep technical knowledge hidden behind the funds. It seems that college students are college students, far from what he can compare with from a technical secondary school.

"Teacher Hao, I toast you!" Xiao Pingxin picked up a glass of beer in both hands and said to Hao Shuang sincerely, "Thank you for telling me all the secrets of this without concealment!"

"Hehe," Hao Shuang picked up the wine glass, touched Xiao Pingxin lightly, and said with a smile: "Xiao Xiao, I have a lot of goods in my stomach, far more than that." Why don't you jump ship to the Xiangyangpo clay mine, and then I can teach you all the things in my stomach?"

Since meeting Xiao Pingxin, Hao Shuang has been thinking about wanting to pull his old subordinate from his previous life over, and since Xiao Pingxin took the initiative to send it to the door today, how could he miss this opportunity.
