High chromium cast steel balls

High chromium wear-resistant ball: It is a kind of crushing medium used in ball mill. The wear-resistant steel ball used for crushing materials in the mill is also called wear-resistant medium for grinding machine. It is a consumable.

Main use: Grinding materials to make the materials finer to meet the use standards.

Application areas：

Metallurgy, mining, cement building materials, thermal power generation, flue gas desulfurization, aerated concrete, magnetic materials, chemicals, water-coal slurry, pelletized ore, slag, etc.

Mining: used for crushers, coal mills, etc. to improve the service life of equipment.

Power industry: It is an ideal wear-resistant material for coal mills in coal-fired power plants.

Petrochemical: Provides wear-resistant protection for pumps, valves and other components.

Automobile manufacturing: Applied to brake pads, clutches and other components.

Cement building materials: Used in grinding mills, ball mills, etc. to improve work efficiency and equipment life.

Main ingredients:

Chromium: The content is more than 10%, and it also contains iron, carbon and a small amount of other alloy elements.

Features:

High hardness: excellent wear resistance, about 2 times that of ordinary low-chromium balls and forged steel balls.

Strength and toughness: good impact resistance and fatigue resistance, can remain stable under harsh working conditions.

High temperature and corrosion resistance: can adapt to extreme environments such as high temperature, high pressure, and high corrosion, such as coal mills in coal-fired power plants.

Production process:

Smelting: Mix the raw materials in proportion and then melt them at high temperature to form a uniform alloy.

Forging: Make the molten alloy into a blank.

Heat treatment: Improve wear resistance and toughness through heat treatment processes such as quenching and tempering.
