Texture profile

Improved high nickel-chromium centrifugal composite casting roll production process, the outer layer to increase the V, W and other strong carbide forming unlimited chilled cast iron, the core element of the high-strength ductile iron.

Outer bainite matrix tissue contains large amounts of eutectic carbides, small MC type carbide uniformly dispersed in the matrix, carbide content of about 25-35%. At the same time the organization also distributed Free State 1-3% graphite.

By optimizing the heat treatment process to ensure the roll has better stress level and suitable hardness.

Main application

• All kinds of strip mill finishing after the period of work roll
• The front end portion of the stainless steel finishing mill work rolls
• The heavy plate mill roughing, finishing work roll
• Mill bearing rollers

Performance Characteristics

• The texture makes a lot of carbide rolls have good wear resistance and surface quality, quality assurance rolled.
• Mill situation for different design optimization carbide and graphite content ratio, improve roll performance.
