Factory direct sale SAG mill Chromium-Molybdenum Alloyed Ball Mill Liner Plates

Generally, Chromium-Molybdenum ball mill liner plate is divided into medium Cr-Mo liner plate (A kind of casting steel with the chromium content at 4-6%, the carbon content at 0.4-0.8%)and low Cr-Mo Liner plate(A kind of casting steel with the chromium content at 1.2-2.5%, the carbon content at 0.3-0.6%). Its distinctive feature is to adopt multivariate alloy design. It increases carbide content in the medium carbon alloyed steel, through increasing the Cr-Mo content, the strong carbide forming elements, so as to improve its heat-resisting, wear-resisting performance. As a result, its high strength, strong toughness and good wear resistance properties represent the relatively high level of metal wear resistant materials.

Processing Technique:

Intermediate frequency furnace smelting high-quality steel scrap and Chrome & Moalloy etc.

Constant temperature casting process ensuring the quality, no solid nonmetallic impurity, nopore etc. Automatic temperature tempering heat treatment process changing the internalorganizational structure, further improving the mechanical properties.

After the Pre-furnace test, semi-finished products and finished products inspection was done by advanced spectrometer and durometer imported from Germany.
