In 2008, he presided over the compilation of industry standards JB/T 10994-20 10 Plastic Lining for Winding Mine Hoisting Equipment and JB/T 10995-20 10 Lining for Top sheave and guide pulley of mine hoist; 20 1 1 formulated the national industry standard for friction linings of mine aerial ropeways, and revised the national industry standard for friction linings of friction hoists and disc brake shoes of mine hoists. At the invitation of the editorial board of Mine Hoist Fault Treatment and Technical Transformation, I participated in the writing of Chapter 13 Mine Hoist Accessories Engineering Plastics. Zhong Shi Institute of Heavy Machinery Engineering Plastics has continuously improved its R&D capability and introduced new products, which has kept the engineering plastics products of Zhong Shi Heavy Machinery Company at the leading level in the same industry. The Wear-resistant Materials Research Institute of Zhong Shi Heavy Machinery Co., Ltd. has been devoted to the research of new metal wear-resistant materials for many years, and can be engaged in the research and development of new metal wear-resistant materials and heat treatment technology, mechanical properties, wear-resistant performance testing and product optimization design. In recent years, the martensite series wear-resistant materials with high toughness and high hardness developed by the institute have occupied a broad market for high-impact wear-resistant materials for industrial and mining metals because of their superior strength and toughness. The research and development of heat treatment process for new pearlite metal wear-resistant materials greatly improves the wear resistance of pearlite wear-resistant steel; Through the optimization design and transformation of large-scale semi-autogenous mill and autogenous mill liner, the impact fracture resistance of products is effectively improved and the service life of products is prolonged, which has won unanimous praise from customers at home and abroad. Zhong Shi Institute of Heavy Machinery Washing Equipment specializes in the research and development and design of coal mine washing products, and makes process and supporting equipment selection for coal mine washing enterprises. Since its establishment, the institute has successively developed and designed four specifications of LL series vertical spiral discharge centrifugal dehydrator, three specifications of ML series vertical slime centrifugal dehydrator, five specifications of TWZ series horizontal vibrating fine coal centrifugal dehydrator, seven specifications of TCL series sedimentation filtration centrifugal dehydrator, seven specifications of GPY series filter, five specifications of XP series selective crusher and XJM series mechanical stirring flotation machine, with the maximum specification of 20m? . Most of these products have reached the domestic advanced level and have been widely used in domestic mining washing industry. Centrifuge products are exported abroad and highly recognized by local enterprises. Institute of Electrical Automation of Heavy Machinery has a group of technical experts and experienced system engineers who develop large-scale electrical drive control and automation equipment. The electric control system and braking control system of mine hoist, automatic integration system of washing equipment, control system of mine mill, GPRS wireless remote expert diagnosis system of hoist and safety interlock system of coke tower have been developed successively, which can provide ideal factory automation solutions for large and medium-sized factories and mines in China. The products developed and designed by the institute can be widely used in mining, electric power, metallurgy and many other fields. Since the establishment of Zhong Shi Heavy Machinery Kiln Grinding Equipment Research Institute, the practical research of the company's kiln grinding products has been strengthened. According to the specific needs of customers, the transmission mode and feeding device can be changed and modified. Relying on the advantages of company 15m CNC gear hobbing machine and φ6×20m sleeper, the Institute independently designed a series of products such as φ4.2× 13m cement mill, φ4.8×74m rotary kiln and φ3.6×6m ball mill, which are widely used in metallurgy, building materials, chemical industry, mining and other industries, and its perfect technical tracking service system has also won the attention of customers.
