Super High-cr Casting Ball

We are engaged in distributing, exporting and trading excellent quality Super High-Cr Casting Ball to our valuable clients.
Casting grinding ball is used in the ball mill in crushing medium, material used in grinding mill.Currently has two formsone is to chromium white cast iron as the main alloy elements referred to as "chromium alloy cast iron, chromium alloy cast iron as the material of the casting grinding ball called chrome cast iron grinding ball;Second, nodular cast iron as the material of casting grinding ball called nodular cast iron grinding ball, including matrix organization mainly through the heat treatment of the bainite ductile cast iron grinding ball or bainite ductile iron grinding ball;To receive matrix was mainly in the heat treatment of martensite ductile iron grinding ball or martensitic ductile iron grinding ball.

1. Raw material: cast ball material for scrap metal

2. The production process is different: cast ball is a simple hot metal injection moulding temper, no compression ratio

3. Shape: ball casting surface has a sprue gate, sand holes and band, and forging the ball surface is smooth, the surface quality seriously affect the deformation of the ball in the grinding process

4. The hardness.Treated surface hardness 50 or more good ball - 56, but the core hardness 30 or less, the overall low hardness.,

5. Impact toughness: cast ball (3% or higher). (J/CM to release or absorb heat energy per square meter).
