High chromium iron

Feature:

We use proper alloying and and related technological measures to make the crusher hammer heads’ 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.

Bimetal compisite material

Feature:

This material adopt special technological process to make two material with different property integrate in the same time when they are liquid state.

The bonded area could reach 100% and the impact toughness of the bonded area can get more than 14J/cm2  ,the working part use high Cr casting iron and adopt directional solidification to make Cr7C3 which included in high Cr casting iron perpendicular distribute to the working surface .

The hardness could reach to HRC62-65,and the impact to toughness(AK) is above 30J/cm2 ,It can resist the cutting from AL2O3 and SiO2 perfectly show the high anti-friction property . the hammer handle with high toughness and perfect combined mechanical properties.the material have both high anti-friction and safety property and solve the contradiction between the hardness and toughness effectively ,make the spare parts fit the wicked working condition.

The lifetime of the hammer which made from bimetal composite material is 2-3 times than the lifetime of normal high Mn hammer .Specially suit for the big crusher hammer ,blow bar and liner of big mill .The effect will be prominent in the wicked condition .It is widely used in limestone ,cementclinker,iron,sandstone,gangue ,basalt and so on.

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.

Medium alloy steel

Feature

The alloy structure cast steel is an iron-carbon alloy formed by adding an appropriate amount of one or more alloy elements on the basis of ordinary carbon steel.

Process technology

According to the different elements added, with appropriate smelting and heat treatment process to obtain high strength, high toughness, high wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, non-magnetic and other related special properties.

Scope of application

It is suitable for producing the wear-resisting spare parts with good mechanical strength and good toughness that are required for various working conditions, and the main steel structure castings with the required dynamic load.
