Roll rings

Compared with steel rolls, cemented carbide roll rings have the characteristics of longer service life, higher cost-effectiveness, higher dimension precision and better surface finish owning to its high hardness, good wear resistance and high modulus of elasticity, thus greatly reduce labor intensity and improve productivity.

Description

The first cemented carbide rolls in China was developed and produced by our company in the 1970s. After more than 40 years of development and constant technological update, we have successfully developed more than 40 series of grades, such as high speed wire roll rings, composite rolls, KOCKS roll rings and special roll rings, which make our product market share is among the best. We have been developed 6 series of roll rings so far, such as YGR series, YGH series, FHL series, PA series, YGA series, PC series. Among them, the high speed wire roll rings have rich grades, which can meet the processing needs of various materials and working conditions. In addition, YGA series and FHL series of high speed wire roll rings have excellent performance in low temperature rolling, special steel rolling and other subdivisions. Their performance is leading in China and has reached the international advanced level. Their customer’s recognition is high and sales volume is rising rapidly. We also have multiple types of composite rolls that "PC series" and "ZJD series" are the most popular grades. They have high tensile strength, heavy load bearing, good wear resistance. And the rolled products has high surface roughness and precise negative deviation control. In recent years, the new “PA-A” series has gained a good reputation in KOCKS rolling mills and its market share has been increasing. The classic series YGR and YGH have been highly trusted by customers for their good versatility and stable performance.

Composite rings

APT

Ammonium paratungstate(APT) is a white crystal chemical used to make tungsten trioxide or blue tungsten oxide for tungsten powder production. It is also used as an additive in petrochemical industry and an intermediate product for tungsten compounds.

AMT

Ammonium metatungstate(AMT) is a water soluble white(or yellowish) crystalline powder.It is mainly used in the production of metal tungsten, alloy steel, fireproof fabric, and ceramic industry.And it is also used to produce various petrochemical catalysts and other tungsten compounds. It is the main raw material of tungsten based catalysts.

Tungsten oxide

The main raw materials for tungsten products and cemented carbides,and theadditives for chemical products such as intelligent glass and thermal insulationcoatings; cathode materials for lithium ion battery; catalysts for petrochemicalindustry, colorants for paints, additives for fireproof fabrics, etc.
