Cone Crusher Mn Liner Manufacture Process and Quality Control

■ Pattern
Wooden pattern are normally used with high precision requirement.
■ Molding
Adopt the alkaline phenolic resin bonded sand in molding process, which guarantee the
high precision and better outlook of the product.
■ Smelting
◆ Material:
The raw material use the scrap steel such as low carbon alloy steel and carbon steel,
which have low carbon, low silicon, low sulfur and phosphorus, and high purity.
◆ Testing:
The chemical composition detection is carried out simultaneously by spectrum and
conventional test during the smelting process.
◆ Refining:
Slag refining technology is used to strictly control the pouring temperature, refine
grain size and remove inclusions
◆ Modification Treatment:
Add specifical additive for high magnese wearing liners, etc.
■ Heat Treatment
The self-designed heat treatment device is used to ensure that the product enters the pool
quickly for heat treatment, preventing the precipitation of carbide structure on products
with thick sections.
■ Blasting
After heat treatment, shot blasting is performed to ensure a smooth surface.
■ Inspection
The whole manufacturing will be controlled following an approved ITP.
