197 1 year transferred to machinery factory of yanhua company until retirement.
He has been engaged in heat treatment technology on the production line for a long time and made outstanding contributions:
1982 successfully developed a complete set of technology of "internal electric heating method" and won the second-class merit of Yanhua Company. Obtained the design and manufacturing license of pressure vessels issued by the Ministry of Labor and Chemical Industry at 1983 and the design and manufacturing authorization certificate of pressure vessels issued by ASME in the United States at 1992. From 1992 to 1995, he won the advanced individual in the competition of "stressing ideals and comparing contributions" in Beijing factories and mines. 1994 was awarded the title of "Excellent Professional and Technical Personnel" by Yanhua Company.
1993 "assembled resistance furnace" was successfully developed. The furnace integrates many modern scientific and technological achievements and patented technologies, which is a revolution in furnace structure and fills the gap in this field in China. Once the former large-scale furnace is built, its shape, size, volume and power are fixed, and it is a "fixed furnace" that cannot be disassembled and moved, thus limiting the scope of application of the furnace and making the field manufacturing and heat treatment of large-scale equipment that is difficult to transport difficult a problem; "Assembled resistance furnace" is a kind of "mobile furnace" that can be disassembled and moved at will, which can change the shape, size, volume and power and solve many problems.
