Internal Duct Liner Introduction
High manganese steel is divided into 5 grades according to the national standard, the main difference is carbon content, which ranges from 0.75%-1.45%. High impact, low carbon content. The commonly used high manganese steel grades and its applicable scope is: ZGMn13-1 (C1.10% to 1.50%) for low impact, ZGMn13-2 (C1.00% to 1.40%) for common parts, ZGMn13-3 (C0.90% to 1.30%) for complex parts, ZGMn13-4 (C0.90% to 1.20%) for a high impact. The manganese content of the above 4 grades of steel is 11%-14%. Manganese content between 11.0%-14.0%, generally should not be less than 13%. There is no national standard for ultra high manganese steel, but manganese content should be greater than 18%.
The impact of high manganese steel mill corrugated liner is used to protect the barrel, the barrel from the grinding body and the material directly impact and friction, but also can use different forms of high manganese steel liner to adjust the grinding body movement, in order to enhance the grinding body of material crushing effect, help to improve the efficiency of grinding mill, increase production, reduce the consumption of metal.
