2、 Main business of the issuer
Since its establishment in 1995, the company has been focusing on the R & D and technical application of new wear-resistant materials, and customized high-efficiency and energy-saving technical solutions for wear-resistant castings for customers. The company is a high-tech enterprise producing medium and high-end wear-resistant castings of ball mills, comprehensive energy-saving technology application of high-efficiency ball milling and controllable ion infiltration (PIP) technology treatment in China. Its main products include wear-resistant material products such as ball mill ball, lining sector, grinding section and hammer head, as well as metal ceramic pip technology processing services and products of various parts and components.
During the reporting period, the company's main businesses mainly include:
(1) Wear resistant materials: on the one hand, it is the application and promotion of high-efficiency ball milling comprehensive energy-saving technology to provide customers in mining, cement and thermal power industries with comprehensive solutions of "increasing production, energy saving, consumption reduction and environmental protection". The main products are wear-resistant products such as grinding balls and lining sectors. On the other hand, it is the application and promotion of crusher hammer. Through the crusher, waste cars, steel and household appliances can be reused to realize circular economy. As the main spare part of the crusher, the hammer uses the force of high-speed rotation to strike and crush the materials. Due to the poor working environment, the hammer head is required to have high hardness and impact toughness;
(2) Controllable ion infiltration (PIP) technology is based on the strict requirements of military industry and high-end equipment manufacturing industry for parts with higher corrosion resistance, wear resistance and fatigue resistance without changing mechanical properties, as well as the development requirements of green manufacturing in China. It realizes low infiltration temperature, thick infiltration layer, green and environmental protection in the infiltration process It can replace hard chromium plating and industrial application. This technology can effectively improve the wear and corrosion resistance of cermet parts and enhance the competitiveness of customer products by treating the surface of parts. The main products and services are cermet PIP products and pip technology processing. The products and technologies of the company's PIP business are widely used in engineering machinery, environmental sanitation machinery, agricultural machinery, medical devices, military equipment, automobile manufacturing, petroleum and petrochemical, mold manufacturing, aerospace and other fields. 3、 Core technology and R & D level of the issuer
(I) core technology
Core technology technical characteristics application products

4. Reduce the ball loading of the ball mill and improve the grinding efficiency of the ball mill.
The structure is composed of wave crest and bottom sector, and the wave crest parameters include front angle β、 Width m and
Height h;
- the lining sector has split design of wave crest and bottom sector, which can be replaced separately after the wave crest is damaged. The lining sector structure of wear-resistant casting is designed, and the bottom sector can continue to be used to reduce the use cost; And new high-efficiency ball technology - wave crest parameters are designed according to the requirements of ball mill diameter, rotating speed, material characteristics, milling fineness and specific surface area; Energy technology
- the split design also reduces the weight of a single lining sector and is more convenient for installation and maintenance,
The security is also greatly improved.
The original design of lining material manganese silicon chromium molybdenum and manganese vanadium titanium new anti-wear cast steel is used for lifting strip
Made with new technology, the wear resistance is better and the impact resistance is greatly improved.
Material characteristic test 1. Three original test indexes: moldability coefficient, grinding efficiency and crushing impact energy;
New technology 2. It can provide comprehensive and accurate information for the subsequent process of grinding ball grading and lining sector design
basis.
1. Long service life and good film removal effect;
PIP surface hardener 2. Good wear resistance, strong erosion resistance and high fatigue resistance; PIP products
