Process:

The advanced technology and equipent,exquisite production technique,strict process control,ensure teh scale of production,in order to meet hte needs of our customers.But we are not content,our goal is to become and international internationalization,wear-resistant materials manufacturing and r&d enterprises.

Process Overview

1.Chemical composition: The chemical composition fo reasonable is all the scientific research personnel after years fumble formed gradually optimized control curve.With unique chemical composition,make steel matching method of toughness and hardness of perfect union.

2.Reasonable matching: Using high temperature melting furnace sink cushion.Fully melters melting capacity and harmful gas discharge capacity,and efficiently solve the problems,ensure segregation of material of ingredients.

3.Temperature controltechnology:Temperature control technology is chromium alloy casting ball is a very important production process of complex,different melt temperature,temperature,injectiong mould temperature and heat treatment temperature.
Directly influence the staility of the product quality.Therefore,the research personnel successfully summarized a set of complete control technology standards,products in almost constant temperature conditions from liquid to solid casting until forming.

4.Quench process:In pouring temperature and temperature in 1,500 degrees Celsius mould temperature when pouring,can make products internal organization and more refined grains,make a dense cabide 2,see anticlinal.In grinding process,change again after the collision carbide substrate,embedded constantly forming cemented layer.Thus teh hardness and toughness in the church,reasonable greatly improves the ball using life.

5.Heat treatment process:Heat treatment process to guarantee the quality of the product is a important process stability.The company adopts the domestic first-class equipment according to different varieties,quenching and specification fo different heat treatment,and the temperature,time and other technical parameters of the best cooperation to quenching.

High chrome cast iron grinding ball

Application: mainly used for mining industry, cement plant, power station, etc.

Abrasion: about (10-50) g/t in cement

Characteristics:

Xin nanfang has the unique automatic production line of grinding cylpebs in China, which is independently researched and self-developed by xin nanfang’s R&D center. With the self-developed raw materials and special heat treatment system, xin nanfang’s cylpebs achieve good properties, such as high hardness, martensite or bainite metallographic structure and good wear resistance, etc.
