Our company's wear-resistant material research institute is a scientific research and production institution that integrates the research and development of new metal wear-resistant materials, optimization design and production of mill liners. This research institute can engage in the research and development of new metal wear-resistant materials and heat treatment processes, mechanical properties, wear resistance testing, and optimization of product design. Our company has a total investment of 100 million yuan and an automated production line with an annual output of 8000 tons of lining plates. After obtaining the environmental impact assessment acceptance, it was officially put into operation. In order to improve the quality of the pearlite wear-resistant chromium molybdenum steel lining plate of large semi-automatic mills and overflow ball mills, the Wear resistant Materials Research Institute has upgraded and developed a new heat treatment process for this metal wear-resistant material. The wear resistance of pearlite wear-resistant steel produced by replacing traditional normalizing process with new quenching and tempering process has been greatly stabilized and improved.To ensure that the chemical composition of the molten steel is completely qualified, we have adopted a four level joint inspection control method, which includes inspection by smelting process employees, sampling by laboratory technicians, sampling by technical department inspectors, and outsourced inspection and calibration; The implementation of limestone slagging technology in the refining process of electric furnace bottom argon and steel smelting has further improved the quality of our company's steel. Our company's gas heat treatment furnace adopts fully automatic control, high-temperature resistant fans installed inside the furnace to enhance convective homogenization heating, and multi-point temperature control for furnace temperature measurement and control. The temperature difference inside the furnace can be controlled within the range, fully ensuring the uniformity of product heating during the heat treatment process. In the cooling process of quenching and tempering of medium and high carbon chromium molybdenum alloy steel (selected material for semi-automatic mill lining plate), our company has selectively selected slow cooling quenching oil as the cooling medium to fully ensure its heat treatment quality. The configuration of the cooling water tank and the strong convection stirring system in accordance with the national standard capacity requirements for heat treatment provides strong assurance for the cooling effect of products that require rapid cooling during the heat treatment process, thereby ensuring the heat treatment quality of the wear-resistant lining plate. In the final inspection process of the product, our company's quality inspection department conducted a comprehensive inspection of the appearance quality, assembly dimensions, and heat treatment hardness of the inspected products with 100% full coverage, ensuring the installation and working quality of the products.Our company has a dedicated R&D team, with 9 R&D personnel, accounting for 20.45%. In 2023, the R&D investment was 1.6 million yuan, accounting for 5.26%. At present, 8 utility model patents have been obtained, 2 invention patents are awaiting substantive examination proposals, and 7 new utility model patents and 2 invention patents have been applied for.
