Molten steel pouring is only a stage of the whole beam casting work, after the pouring is completed, the beam also needs to be buried in the sand box for a long time to cool, until the surface temperature drops to about 300 degrees, and then the shape cleaning begins. (Look!) WWWļ¼
The clean-up was painstaking, with dozens of workers braving the heat to carefully uncover the lid of the sand box and shovel by shovel to reveal the castings hidden inside. Whereas the modellers used a lot of steel bars to fix the sand cores in the middle, they now have to use gas cutting guns to cut off the bars one by one, pry them open, and then clean the sand in the middle of the castings.
After half a month of hard work, the sand mold was finally dismantled. Workers drove several large cranes to lift the more than 300-ton castings onto the battery transporter, and then transported them to a specially built heat treatment furnace where they were normalized for five days and five nights to meet the performance requirements of the design.
Further down is the machining of the beams. This workpiece, which is several hundred tons, is much larger and heavier than all machine tools, and there is simply no machine tool that can put such a workpiece. Of course, there is a solution to the problem, which is to make the machine revolve around the workpiece. At the most tense time, in several directions of the beam, several machine tools are started at the same time, boring, tapping, grinding, and getting rid of it is a scene of ants gnawing bones.
Just one beam tossed hundreds of people in more than a dozen different jobs for months. In addition, there is a series of work such as the laying of the base, the installation of the column, the lifting of the beam, etc., and the hardships in the process are needless to say. After the installation of the large structural parts, the workers began to install the mechanical, hydraulic and electrical systems, which is equivalent to equipping the hydraulic press with muscles, blood vessels and nerves, giving it life.
This reflects the advantages of Hanhua as a large-scale equipment manufacturing enterprise. After more than ten years of development, Hanhua now has a large number of talents in all aspects, just as many as hundreds of senior technicians, it can be said that no matter what the process, Hanhua can organize a team of workers and technicians who can be called elite soldiers.
From the initial project to the hydraulic press standing majestically in Xunyang Zhoutou on the south bank of the Yangtze River, unknowingly, a year has passed quietly, and Hanhua finally ushered in the celebration of the thermal load test of the hydraulic press.
As early as a year ago, He Haifeng told Lin Zhenhua that this 15,000-ton hydraulic press is not only the property of Hanhua, but also the equipment of the whole country. On the day of the commission, hundreds of people, including representatives of several major ministries and commissions and hundreds of domestic equipment companies, came and squeezed the entire test site.
Lin Zhenhua, Xiang Zhe and other executives came to the scene, and at such a grand celebration moment, they had to accompany every guest who came to congratulate.
"Comrade Zhenhua, you Hanhua Heavy Industry has done a great good thing that benefits the country and the people! It can be said that the benefit is in the present generation, and the merit is in the future. Naturally, it was the leaders of the ministries and commissions who were in high positions who spoke like this.
"Mr. Lin, compared with your 15,000-ton hydraulic press, our hydraulic press has become old, weak, sick and disabled. Well, your experience in building hydraulic presses can't be kept secret. "This is from the peers of Kamizhong, Ichiju and Nie, and their eyes are full of jealousy, and they are eager to go back and report to their superiors and ask for the same or even bigger hydraulic press to be built in their place.
"Mr. Lin, the two of us have been working together very well, and in the future, brother, I have any big pieces to forge, and Mr. Lin should give priority to arranging it." Those who say this belong to the enterprise that does not have a hydraulic press and expects to borrow Hanhua's hydraulic press to make large forgings in the future. ..., among all the guests, there are several very special, including Lin Zhenhua's mentor in his previous life, Professor Yao Heliang of the Department of Mechanical Engineering of Huaqing University.
"It's just amazing!" Yao Heliang circled around the hydraulic press a few times, and with his professional level, he could naturally see that this hydraulic press has unique features in terms of automation level, precision, and reliability. He instructed Lin Zhenhua: "Xiaolin, the experience you have formed in the construction process and the problems you have encountered must be completely sorted out and given to us." The experience and data of these practices are very valuable. ā
"Teacher Yao, don't worry, we have a complete file of all these materials, Teacher Yao, we can provide them at any time when you want them." Lin Zhenhua held the old man's arm and said affectionately.
"Xiaolin, I didn't misread you, when you sent your sister to Huaqing to report, your company still only had one hundred and ten people, and you survived by doing some iron for others, right? It's only been more than ten years, and a world-class 15,000-ton hydraulic press is actually from your hands, which is amazing! Yao Heliang patted Lin Zhenhua's hand and praised.
"This is also thanks to the talents cultivated by Mr. Yao." Lin Zhenhua hurriedly said modestly, "In our Hanhua Heavy Industry, we have the most students who graduated from Huaqing, and they are all the people who take the lead in various positions." ā
Gu Jiahua, the new general manager of Xingbei Heavy Machinery, also came, after he took office, he adopted a policy of close cooperation with Hanhua Heavy Industry, and successively sent a group of engineers and technicians such as Zhang Yuquan to assist Lin Zhenhua in the construction of the hydraulic press, so in today's ceremony, he also has some sense of meritorious. After seeing the appearance of the hydraulic press, Gu Jiahua said to Lin Zhenhua with a smile:
"Xiaolin, the merits are complete! made such a big play, so that my brother and I looked red. ā
Lin Zhenhua hurriedly handed Yao Heliang over to Liu Zhaohua to take care of, walked two steps by himself, came to Gu Jiahua, shook hands with him, and said: "What did Mr. Gu say, if there is no strong support from Mr. Gu, relying on our Hanhua family alone, to overcome so many technical difficulties, I'm afraid it's enough to choke." ā
"No, no, I knew when I was in the Ministry of Petroleum that there was nothing difficult in front of Xiao Lin." Gu Jiahua said.
"Ashamed, ashamed. In front of a big brother like Xingbei Heavy Machinery, we will always be just recruits. ā
"The newborn calf is not afraid of the tiger, but the afterlife is terrifying, those of us who are big brothers are really backward."
"Mr. Gu is polite, if there are any large forgings in the future, just take them, in terms of this processing fee, I am in charge, and I will give you a 20% discount."
"Hahahaha, Xiao Lin is really shrewd, I thought that with the friendship between the two of us, you could directly give us the fee for free. It's been a long time, and it's only eight folds. ā
"Well, we're a small profit, and it's really hard to get rid of the fee. Mr. Gu also knows that as soon as the hydraulic press is turned on, the electricity and water bills are not a small amount. Also, the cost of daily maintenance is not low, so ......"
In the greetings of giggling, it was time for the test run. Liu Zhaohua waved a small red flag, and all the guests retreated outside the safety line, holding their breath, waiting to watch the test scene.
A large crane hoisted a large forging weighing more than 100 tons in front of the hydraulic press, and the automatic forging manipulator stretched out the caliper, clamped the forging, and sent it under the forging hammer of the hydraulic press. The workers in the control room pressed the button, and the forging hammer of the hydraulic press fell with the force of Wan Jun. The black oxide scale on the forging peeled off, revealing a reddish core, which was constantly changing shape like a soft dough under tremendous pressure, and in a few moments, a large spindle had been formed. ..., "Wow! Warm applause rang out in the newly completed hydraulic press workshop, and everyone couldn't help but slap their hands painfully. Everyone is an industrial person, and they all know how such equipment can improve the industrial level of the whole country.
The forging was hoisted away by the crane, and the hydraulic press regained its calm, standing calmly like a swordsman who had just performed extraordinary skills, accepting the admiration of everyone.
The staff of Hanhua had already set up a simple platform in the spacious place of the workshop, and He Haifeng, who had come to congratulate him, boarded the platform accompanied by Lin Zhenhua. He first read out the congratulatory letter from Vice Premier Tang of the State Council, and expressed a high degree of affirmation for the successful construction of a 15,000-ton hydraulic press by Hanhua Heavy Industries. Subsequently, on behalf of the State Development Planning Commission, he put forward further requirements for Hanhua, which was nothing more than making persistent efforts to bravely scale new heights. He Haifeng has said things like this countless times everywhere, and it is really smooth.
The rest of the ceremonies are also the same old-fashioned, the guests congratulate, the host thanks, firecrackers, and then everyone goes to the banquet held by Hanhua, etc., these do not need to be repeated.
"Xiaolin, the 10,000-ton hydraulic press has finally been built for you, do you have any plans for the next step?" After the whole celebration, He Haifeng came to Lin Zhenhua's office and talked with Lin Zhenhua.
Lin Zhenhua replied: "Yes, we are asking Huaqing University to design an 80,000-ton die forging machine for us, which is the key equipment for us to manufacture large gas turbines. ā
"Your heart is really not small." He Haifeng sighed, "At your development speed, you will soon become one of the top heavy industry groups in China." ā
"Being the best in the country is not our goal." Lin Zhenhua said with a smile, "Our goal is to be one of the best in the world." ā
He Haifeng said: "Don't be ambitious, the strength of the international heavy industry giants is still very strong. I've heard that you've been competing with Nishihu for the market lately, what's going on now? To be honest, I've been sweating for you all the time, Xihu is not a paper tiger, and when you really want a bayonet to see red, it will bite people. ā
Lin Zhenhua sneered: "There are times when tigers fall in Pingyang, according to our observations, Xihu Company is about to face a huge crisis. ā
