At the age of 72, I was supposed to be at home for the age of the whole year. The old man Zhou Jiaxuan, who lives in the front of the road, is retiring, and still struggles to find the first line of invention. In June last year, his hot-squeezing gear bar and slice gear forming method won the national invention patent, which is the second invention patent he personally obtained in 7 years. One afternoon recently, the reporter went to Zhou Jiaxuan's home for an interview. Zhou Jiayu, who graduated from the Metallurgical Department of Shanghai Jiaotong University in 1961, worked in Shandong Qinggang and Laiwu Steel for a long time. He returned to his hometown Zhenhai in 1986 and retired in 1996. "Away from the busy work, I am not used to it." He admits that the retirement after retirement makes him very uncomfortable. An occasional opportunity allowed Zhou Jiaxuan to reconnect with technology research and development. In 2003, when chatting with the daughter-in-law who worked in the media, he learned that the quality of the raw material steel pipe in a certain enterprise in our district was not enough, resulting in a high scrap rate of the produced bearing rings. Zhou Jiaxuan, who has been immersed in the steel technology industry for more than 20 years, realized that developing a new process for preparing steel pipes is the key to solving this problem. “The quality of the pipe making process directly affects the quality of downstream products such as fasteners, bearings and gears.†Since then, Zhou Jiayu has embarked on the journey of inventing the alloy steel horizontal reverse extruder. In January 2010, the invention officially obtained the national invention patent, filling the domestic gap. He introduced that compared with the existing positive hot extrusion pipe making process, the reverse hot extrusion process can not only improve the precision of the finished seamless pipe, but also requires only one heating from the steel billet to the finished seamless pipe, one perforation. Extrusion. The simplification of the production process makes the process nearly one-third energy-saving, greatly reducing production costs. When he returned to the first seven years, Zhou Jiaxuan couldn’t help but feel that “it is not easy to turn ideas into reality.†The primary problem facing him is to create the first domestically produced seamless pipe equipment using reverse hot extrusion. This involves related disciplines such as mechanical manufacturing, metal processing, and mold design. He has almost no experience from scratch. Going to the library to check information, buy books, and ask for help from students in the field of mechanical research. It took Zhou Jiaxuan more than two years to become proficient in mechanical manufacturing. Investigating inventions requires not only time and effort, but also funds. In 2005, Zhou Jiaxuan spent 120,000 yuan to purchase an old equipment for transformation into a reverse extruder. In the past seven years, he and his wife saved more than 200,000 yuan in savings on patent inventions. There have been relatives and friends who are puzzled by his actions, but Zhou Jiaxuan persisted. "A patent can only reflect its value if it realizes the transformation of results and helps the society to develop." Zhou Jiaxuan has a unique understanding of patents. In 2009, he and two friends jointly established Jiuli Hot Extrusion Gear Rod Manufacturing Co., Ltd., and prepared to convert the results of the two invention patents. "It is expected to be officially put into production in the second half of this year." The results are in the past, and today's Zhou Jiaxuan is still very strong. He hopes to complete his third invention patent before the age of 75 - oxygen top-blowing converter spiral oxygen gun and vortex steelmaking method.
