High chromium iron

Feature:

We use proper alloying and and related technological measures to make the crusher Blow Bars’ surface hardness reaches more than 58HRC ,  during the process of wearing will maintain high hardness and high wear resistance.

Technology process

The working part of hammer head we use the technique of directional solidification to make Cr7C3 type carbide is perpendicular to the part.The macro-hardness and micro hardness of carbide can be improved without reducing thoghness.

Application

Suitable for making wearable spare parts with lower impact load and simpler shape.

1:There are no exact corresponing value between rockwell hardness(HRC) and brine hardness(HB),so ,this two kind of hardness value can be inspend used 。
2:The hardness in the 40%deepness of casting section should be lower than 92% hardness of surface.

High Manganese Steel

Feature

High manganese steel refers to high alloy steels containing more than 10% manganese. The biggest features of high-manganese steel are:

The greater external compressive stress or impact load, the more conducive to the formation of hardened layer, so the higher the wear resistance of the casting;

With the gradual wear of the hardened layer, new work hardened layers will continue to form under the influence of external compressive stress or impact loads. Therefore, it is suitable for making wearable spare parts that are subject to high impact load and wear for a long time, and is widely used in metallurgy, mining, building materials, railways, electric power, coal and other broken grinding equipment.

Ceramic metal composite

Ceramic metal composite wear-resistant material is a kind of casting infiltration technology to evenly distribute cermet particles on the working face of wear-resistant spare parts. By optimizing the chemical composition of high chromium wear-resistant materials, cermets are embedded in the easily worn parts to make them have excellent properties of wear resistance and high temperature resistance.

In the honeycomb structure of high chromium cast iron, because the hardness of ceramic (particle) is hv2100 and the hardness of high chromium cast iron is HV < 900, the ceramic metal composite is widely used in various wear fields, and its service life is 3-4 times longer than that of single high chromium cast iron. Thus, the running time of wear-resistant spare parts is prolonged, the maintenance times and time are reduced, and the production efficiency is improved.
