High Manganese Steel Ball Mill Liner
Introduction
product description
High-manganese steel ball mill liners contain 10% to 15% manganese, and the carbon content is generally 0.90% to 1.50%, most of which is above 1.0%. At low impact loads, it can reach HB300~400, and at high impact loads, it can reach HB500~800. With different impact loads, the depth of hardened layer can reach 10~20mm. High hardness hardened layer can resist impact abrasive wear. High manganese steel has excellent anti-wear performance under strong impact abrasive wear conditions, so it is commonly used in mines, building materials, thermal power and other mechanical equipment to make wear parts. Under low-impact working conditions, high-manganese steels cannot exert the characteristics of materials because the work hardening effect is not obvious.
Production Process
Intermediate frequency electric furnace smelting and microalloying high-quality scrap steel, manganese alloy and other alloy materials, quenching and tempering, and then sand casting molding; thermostatic pouring method to ensure that the product is free of sand, porosity, collapse and other quality defects;
The automatic temperature control heat treatment and tempering process changes the internal structure of the liner and further improves the mechanical performance;
Pre-furnace, post-furnace, semi-finished products and finished products adopt advanced spectral detection to ensure stable chemical composition and performance.
Note
If the above products need to adjust the chemical composition or add other alloying elements, Contractually agreed.
