The hammer head of the crusher adopts the lost foam composite casting process,which is matched with high chromium alloy and various alloys.It is loaded with precious metal elements such as molybdenum,vanadium,nickel,niobium,tungsten,titanium,rare earth,etc.After water toughening treatment,the Rockwell hardness reaches 62-65,and the service life is 3-5 times that of a high manganese steel or forged hammer head;The hammer head is made of high chromium cast iron,and the hammer handle is made of low alloy steel with strong toughness.The combination of the two is achieved through a hydrothermal composite production process,ensuring that the product does not break.It is a combination of steel and iron,and has good comprehensive properties such as

Advantages of bimetallic composite hammer heads:

1.Crusher Hammer Head Process

The hammer head of the crusher is made of high chromium alloy material,and the hammer handle is made of low alloy steel material with good toughness.Two different materials with different properties and effects are melted into one by thermal composite in a liquid state,with a composite area of up to,solving the problems of fracture,falling off,and turning of the hammer head that are easy to occur in alloy inlay and double composite casting,and improving the usability of the hammer head.

2.Element ratio of

In addition to elements such as carbon,chromium,silicon,manganese,copper,molybdenum,etc.,the hammer head of the crusher also adds elements such as vanadium,titanium,antimony,rare earth,etc.to refine the grain and improve the degree.

3.Optimize heat treatment process

The heat treatment process for the hammer head of the crusher is to heat it to 1100℃for insulation,then discharge it from the furnace,undergo chemical water toughening treatment,and then undergo low temperature tempering at 600℃.The furnace is air-cooled,and the hardness can reach 62HRC-65HRC.The process is mature,and the company has very high requirements for the hardness and toughness of the hammer head.It is our mission to be responsible to customers.

4.Wide range of performance applications

The hammer head of the crusher has high wear resistance and performance,effectively solving the contradiction between hardness and toughness.It is designed for crushing limestone with abnormal SiO2 content,especially suitable for crushing hard,high SiO2,and strong abrasive limestone.It is suitable for working under harsh abrasive wear conditions and has a longer service life than ordinary high manganese steel hammers by more than 50%.

5.Good economic benefits

This hammer head is not easily broken and has a service life four times that of a forged hammer head or a high manganese steel hammer head.It meets the demand for frequent replacement of hammer heads in sand and gravel production lines and has economic benefits.

6.Provide humanized services

The hammer used can be customized according to the diagram.If there is no diagram,we will have surveying and mapping personnel to help you customize after surveying and mapping.
