mining picks for roadheader coal mining pick picks for mining machinery

Specifications

A. Steel material.

We only use quality 42CrMo as steel body. This kind of steel of ultra high strength steel, 

intercritical quenching conditions can be obtained in martensite and a small amount of uniformly 

distributed fine ferrite, this organization under the premise of ensuring the strength of improved 

toughness. Has high wear resistance, high fatigue limit, strong toughness, which is to ensure the 

quality of cutting teeth of the basic factors.

                                Chemical  composition

B.Heat treatment Technology

 In the light of bit alloy heads around the portion of generally wear,

 we developed the super abrasive cutting tooth, in this area have been adopted for ultra

 deep w alloying process, while the hardness is not greatly increased, but the infiltration 

of component greatly enhanced wear resistance, but still maintain toughness, and using

 high quality imported hard alloy head. After many trial effect of mine, has reached or even 

exceeded imports pick.

The coal bits are mainly used in coal and mine drilling. 
We can manufacture all kinds of bits and shells according to customer's special requirement.
