Jianglu Group heat treatment workshop, 30 quenching furnaces are working.
On July 11, when the outdoor temperature was 35 °C, the thermometer hanging on the wall of the heat treatment workshop of Jianglu Group had exceeded 40 °C.
As soon as I entered the workshop, a heat wave hit my face, 30 quenching furnaces were working, high temperatures filled every corner of the workshop, and the air was stuffy and dry.
As the stove opened little by little, a scorching heat rushed out.
The workers need to hang the product on the crane chain with a long hook.
"It's out right away, everyone get ready." At 9 a.m., the first products are ready to be baked. I saw Liang Jian, the electrician shift leader of the heat treatment workshop, wearing cotton gloves and holding a long iron hook about a foot away from the furnace door, waiting for the product to be released.
As the furnace door opened little by little, a scorching heat rushed out, the pores of the whole body opened instantly, and beads of sweat flowed down the forehead unconsciously. Liang Jian skillfully hooked out the product parts one by one with hooks, water quenching, oil quenching, air cooling... Everyone's face was flushed by the light of the hearth.
The product is being quenched with oil, and the fire light reddens everyone's face.
Rapid cooling further strengthens the hardness of the product.
"Since the summer came, our shift moved the working hours by an hour and went to the work site at 6 a.m. to open the furnace so that it was not too hot." Liang Jian said that after the start of construction, the entire workshop will reach more than 40 degrees, and the closer to the stove, the hotter it will be, and even reach 50 degrees in the afternoon.
After a while, the worker's clothes were soaked with sweat.
Heat treatment is an important production process in the manufacturing process of products, and every step can not go wrong. Among them, the control of the process is the most critical, it is necessary to control the heat treatment equipment and various temperature parameters, the holding time and the cooling method, these details are the key to ensure product quality.
"Many parts and components of important equipment must be hot processed and quenched to ensure quality, and we keep an eye on it, with a solid heart." Liang Jian told us that across the hall from the workshop is the air-conditioned staff lounge, but there are few people lingering, not because people don't want to feel the coolness and comfort here, but because of their sense of responsibility.
Taking advantage of the gap, Liang Jian hurried to the lounge to drink saliva, and after a while, he went to the next round of work.
Although it is hard to work in the heat wave every day, the members of the electrician class are very proud, because the heat treatment workshop can process more than 50,000 tons of products every year, and the company's important military parts are built by them, and all production work is completed on schedule with quality and quantity, and the team has won many honorary awards such as "Hongqi Model Team".
