As soon as the electric furnace was turned on, Da Liu was called to go to the section. Da Liu shook off his slender legs and trotted past the technical group almost without touching the ground. A young man happened to come out of the technical group, and Da Liu shouted: "Xu Li? Alas not? Admit your mistake. He turned his head and said, "I think about it, Xu Li's guy seems to have gone abroad." ”

The young man in the technical group laughed behind his back and said, "Oh yes, Xu Li has gone to the UK." ”

The office of the smelting section is next to the technical group, and it is also an old-fashioned bungalow with gray brick walls and double doors. As soon as Da Liu entered the door, he habitually jumped down with one foot, like jumping into a sand pit. I couldn't help but say: "This old factory building of Yan Xishan is strange, and the ground is a little lower. We can't afford to be inferior. Duan Chang, is there something good? ”

"Something good? It's a good thing. Duan Chang pouted his buckteeth and spoke in a dialect: "It's all here, who else is there, the fourth class didn't come?" It's coming, it's coming. Okay, let's take a moment now and have a little meeting. Some of the team leaders have just gotten off work, and some are at work, well, that's the case. Isn't the factory going to be on the shearer, not only to be on it, but also to become a mechanical pillar product," an old engineer on the side added softly: "Pillar fist product." ”

"Oh, there was nothing to do in our workshop, but our Director Zheng insisted on winning the steelmaking and casting task of most of the components. There are mainly shearer rocker arms, and our workshop has experimented with rocker castings in the previous section, which is said to be OK? Wow? Wang Gong? ”

Engineer Wang on the side whispered again: "There is still a bit of a problem, in fact, it is not the problem of our steelmaking, the main thing is that there is a little defect in casting," said and nodded, seeing that everyone was staring at him, he simply introduced, "At that time, the factory carried out some analysis of the structural characteristics of the castings, such as the design of the pouring system, as well as the placement of the internal and external cold iron, such as taking measures to improve the concession of the sand core, formulating a reasonable pouring process, etc., and reformulating some measures." As a result, some time ago, our newly appointed director Geng, the deputy chief engineer, Director Zheng of our workshop, and the engineers of the precision casting workshop held several meetings together. In the end, Director Zheng proposed a plan, which seems to form a sequential solidified temperature gradient in the casting, so as to prevent the defects of shrinkage porosity, shrinkage porosity, cracks and slag inclusion. Some time ago, after the machining and flaw detection inspection of the shearer workshop, the product basically met the technical requirements. ”

Lao Wang Gong's voice was not high, and he was unhurried to speak, but he seemed to be very clear about this matter. After saying that, there was no expression, as if it was just like eating and sleeping every day.

Several team leaders in front of the furnace all stared at Lao Wang Gong with big eyes and had nothing to say.

Lao Wang Gong taught students in technical schools, he looked at everyone, and suddenly asked Zhang Duanchang: "Alas? Aren't there a few new technical school students in front of our furnace? ”

Zhang Duanchang looked at Da Liu and them, and said lightly: "Hey, there are one or two technical school students in each group, but a few of them have gone to the entrance examination, right?" Da Liu, Guo Guozhu in your group? Coming today, right? ”

Lao Wang Gong immediately said: "Oh, Guo Guozhu, I went to the technical school two years ago to give them a smelting class, as well as metallurgy, which was taught by Li Gong from the technical department of the factory." Their students are okay this time, and they know more, because their students themselves are high school students who went to technical schools. ”

Zhang Duanchang seemed to remember something, and suddenly interrupted Lao Wanggong's words: "Then who, Yu Wen didn't come?" He can do it too. ”
