Soon the test results came out, the results of the first screening, the fineness modulus was 2.63, the second result was 2.67, so the average was 2.65, but at this time the newcomer was wrong, that Xiao Zhang calculated, and he wrote a 2.7. Pen ~ Fun ~ Pavilion www.biquge.info 【】

Li Liangfeng hurriedly said: "Xiao Zhang, you miscalculated again, how did you do it?" Didn't I tell you? We are engaged in concrete technical work, and the rounding learned in school cannot be used! You say, what should be this correct outcome? ”

Xiao Zhang scratched his head, indicating that he didn't know.

Xiao Liu hurriedly said: "I know, I remember what Li Gong told us." It seems like so, the result should be 2.6, right? ”

Li Liangfeng nodded and said, "Well, that's good!" I'm going to tell you again today, our rules for data recording and calculating amendments. As for the data revision, you remember, it's called rounding up to five odd and even. What does this mean? That is to say, the calculated data, we need to modify to the specified number of decimal places according to the specification, it depends on the number before and after it. If the back is four, then all abandoned, if it is six, it must be entered by one, which is the same as our primary school mathematics, the key is to look at this five, if there is no valid value behind five, then you have to look at the previous one, like this one in front of the 6, this is a double number, then the back of the 5 has to be abandoned, if the front is a singular number, then enter one place, for example, if the result is 2.75, then it is different, then this 5 has to enter, the result is 2.8. ”

The two newcomers hurriedly nodded like chickens pecking rice.

Li Liangfeng lost, he knew that his experience was definitely not enough, it was only a few months, and the official production had only begun, and he was also a newcomer.

Qin Haijuan said with a smile: "Okay, everyone knows, everything must be spoken with data, not arbitrarily." Now re-open the mix notice, production will start soon, our technical department can not hold back! ”

Li Liangfeng returned to the office and re-opened a coordination notice, this time there was no problem, Qin Haijuan signed the name there with a brush.

Li Liangfeng took the mix ratio notice to the central control room of the mixing building, and the production was about to start, just waiting for his mix ratio notice.

What the technician has to do now is to supervise and audit the operator to input the concrete mix into the industrial control system to see if it is correct, which is a very critical link, and sometimes the wrong one can have serious consequences. Think about it, if the mix ratio is wrong, can the concrete produced be without problems? The most serious is the cement and admixture input error, if the cement is less than dozens of kilograms, then the strength may drop to 10 megapascals, or even more, the admixture is also very important, if more will produce non-condensation and other consequences, are serious quality problems.

Therefore, after the operator loses the mix ratio, the technician and the operator need to review it together, and then both people have to sign on the mix ratio input confirmation sheet.

Fortunately, there are very few production tasks now, so it is impossible to make mistakes, only when the production tasks are very busy, there may be mistakes, and some technicians are not responsible, and they do not sign casually without review, which leads to many cases of quality accidents.

After the mix ratio and production task information are entered, we are waiting for the production scheduling notification to issue the material.

After a while, the production scheduling shouted in the walkie-talkie, the two lines were produced at the same time, after all, the two pumps were started at the same time, so the two lines could fully meet the requirements. Especially in the beginning.

On the industrial control computer, the data on the interface is constantly changing, and the image of the industrial control schematic diagram also has a color to indicate the operation, which is much better than the previous mixing building, you must know that this is now the most advanced concrete batching plant in the world.

At present, the first tray of concrete mainly relies on visual inspection to judge the slump size and working performance. Of course, as long as there is no problem with the mix ratio, the concrete produced basically meets the requirements, but sometimes the moisture content of sand and gravel will fluctuate, so this requires the operator to adjust it in time.

The first tray of concrete is mixed to 30 seconds, and the slump of the concrete is preliminarily judged by the host ammeter on the mixing table, which requires long-term accumulation of experience. Fortunately, some have been produced before, so it is not too difficult to judge now, roughly about the same.

The operator, Xiao Lin, glanced at Li Liangfeng and asked, "Li Gong, I think this plate has a slump of one hundred and two, it should be able to put the material, right?" ”

Li Liangfeng nodded and said, "Okay, you release it, I'll take a look!" ”

Through the camera at the discharge port of the mixer, the concrete slump can be visually measured, of course, you can see more clearly when you go to the mixer, Li Liangfeng does not dare to be careless, this time it is an important concrete poured. He ran outside and looked at the mixer discharge.

As the mixer door opens, the concrete crashes down like a mudslide, forming a vortex in the feed hopper of the mixer truck, of course, the concrete cutting state of different raw materials will be different for different strength grades.

Li Liangfeng made a preliminary judgment, but it was similar to what the operator said, this is only the first plate, and there are two more plates behind, and after the end, samples will be taken for testing, and then you can verify whether the visual inspection is accurate.

Qin Haijuan also came up, this time it was an important task, and she was also afraid that there would be problems.

Looking at the monitoring screen, she felt that there was no problem, after all, the mix ratio was still calculated more accurately, and there would be no problem under normal circumstances.

Next, the second and third trays of concrete were successfully put into the concrete mixer truck, and the two lines produced their first truck of concrete almost at the same time.

At this time, the second car can not be produced temporarily, which requires the technical quality department to complete the opening appraisal and confirm that the concrete quality meets the requirements before continuing to produce.

Li Liangfeng and Qin Haijuan both came down, and four newcomers from the technical quality department took samples below.

A newcomer is a newcomer, Xiao Zhang was careless, he didn't pay attention to the material, and he was a newcomer who really hadn't mastered it, and all of a sudden the concrete came down a lot from the top of the bucket, and he was stupid and didn't know how to move the handle to the forward position.

The concrete rushed down like a mudslide, and the trolleys were almost submerged.

Li Liangfeng secretly said that this guy is too stupid, but his feet are not stopping, and he hurriedly ran over and moved the handle of the tank controlling the mixer truck back to the forward position, if it is slow, I am afraid that a cubic meter of concrete will be released.

That Xiao Zhang was also frightened, his face was also red, and he didn't dare to look at Li Liangfeng and Qin Haijuan.

Li Liangfeng reprimanded loudly: "How did you do it, you can't put a single concrete, look at how much concrete is lost?" If it's shipped to the jobsite and the customer finds that it's so much less, it will affect the company's reputation, you know? ”

Qin Haijuan saw that Xiao Zhang was about to cry, and hurriedly said, "Okay, Li Liangfeng, it's not to blame you, the master, for not teaching properly. Don't talk about these, now do the opening appraisal, the construction site is still waiting for concrete! (To be continued.) )
