[pursuit of ingenuity] Over the past 20 years, Jia Chuncheng has adhered to the front line of smelting production, constantly overcome difficulties and make self breakthroughs. He has grown from an ordinary worker to a special technician of Chinalco Northeast Light Alloy Co., Ltd., and won the National May day labor medal in 2022. He engraved his beautiful youth on the machine for casting "great country and heavy weapon". "This is my main battlefield" "The first time I went to the melting and casting site, the high temperature of nearly 50 degrees Celsius was the first test. I didn't sweat and sweat all over my shirt." Recalling his first job as a foundry worker in 1996, Jia Chuncheng said that the working environment at that time was far beyond his imagination. Known as "the cradle of China's aluminum magnesium processing industry", Dongqing has exclusively produced more than 1000 specifications of products in national key projects such as the aerospace Long March, Shenzhou, Chang'e and Tiangong series, and a number of technologies have filled the domestic gap. For the fledgling Jia Chuncheng, the high-temperature working environment is only one aspect, and the greater test is the operation technology and casting process of the casting machine. There are nearly 100 varieties and specifications of alloys, and many people are afraid of the technical difficulty and process complexity. But Jia Chuncheng was not "bluffed", and he had the strength to admit defeat: "I don't believe it, I can't attack this position." Since then, Jia Chuncheng has worked one hour in the morning and one hour late, learning from the master, asking the technicians and digging from the books. He "climbed and rolled" on the casting machine, devoted himself to studying technology, familiar with the process flow, and took the post as his home. Over the years, he quickly became the backbone of the foundry post. Now Jia Chuncheng still appears in the workshop early every day to understand the actual production situation of each shift, check the implementation of process discipline and technical requirements, and correct the stop loss in time for the problems found. When he meets a busy post, he will go up in time. "It's nothing to be bitter or tired. This is my main battlefield. I want to do a good job." He said. Pursuit of perfection and innovation Jia Chuncheng's father worked as a worker all his life, and his master LV Yanze was also the winner of the National May Day Labor Medal. As a result, Jia Chuncheng did not stop studying new technologies even though he had many honors. His motto is the ultimate pursuit. The north line operation area of the melting and casting plant where Jia Chuncheng is located undertakes the ingot production of Dongqing company and the ingot production of most high-end materials such as aerospace. Whenever there is a task of R & D and trial production of new materials, Jia Chuncheng participates in it for the first time. In order to meet the aluminum requirements of domestic large aircraft, Jia Chuncheng shuttled between the melting furnace, stockyard and conference room day and night. His notebook was filled with ideas and data, and finally solved a series of problems such as ingot non forming. Zhao Yong, leader of the melting and casting production line of Dongqing company, said that in a difficult problem attack, Jia Chuncheng led everyone to tackle key problems for seven consecutive days, and strive to achieve the ultimate in each link. After everyone else has a rest at 12 pm, he has to sort out the situation of the day again to prevent making the same mistakes. In 2016, Dongqing company established a model worker Innovation Studio under the name of Jia Chuncheng. With the development of science and technology, it is urgent to upgrade the equipment of the old production line. Jia Chuncheng Labor Model Innovation Studio took several months to complete the automation upgrading and transformation of the old line, realizing the automatic processing of round ingots, greatly reducing the labor intensity of workers, increasing the production efficiency by 30% and the processing yield by 8%. In 2021, relying on the studio, Jia Chuncheng independently designed and completed the professional electric control preheating system, got rid of import dependence and saved hundreds of thousands of yuan. A single flower is not spring A single flower does not make spring, while one hundred flowers in full blossom bring spring to the garden. "Casting work is hard and tiring, demanding, and it's not easy to learn and stick to it." When the studious young man asked him for technical questions, Jia Chuncheng explained it patiently and carefully, and demonstrated it over and over again if he couldn't speak clearly orally. "When technology is passed on, it is alive. Young people grow up rapidly, and the company as a whole will become stronger and stronger." Jia Chuncheng said. In recent years, Jia Chuncheng has passed on the long-term accumulated operation skills and work experience of high skilled talents represented by model workers to ordinary employees through model workers' post demonstration, special lectures, technical exchanges and other activities. Many of his apprentices have become the technical backbone of the company. Using the platform of labor model innovation studio, he helped young people grow up. So far, he has overcome 14 important innovation projects and created economic benefits of millions of yuan. "In my impression, master seldom has a rest on weekends and holidays. His mind is on work." Liu Shuai, the apprentice of Jia Chuncheng's "post-90s generation", has grown rapidly under his "teaching by example", and has become a leader among his peers. It is these skilled craftsmen and skilled workers that have laid a solid foundation for the development of enterprises. In the first quarter of this year, Dongqing achieved a year-on-year increase of 21.4% in the output of high-end alloy products and 252% in operating profit. (outlook new era)
