Blow Bars for Impact Crushers Product Description:
The high-Cr and -Mn based KM Series demonstrate the excellent characteristics of their heat- and wear-resistant wear plates in blast furnaces.High chromium white irons are commonly used throughout the mineral processing industry to handle erosive and erosive-corrosive slurries.
These alloys are used in critical wear areas in the form of castings, or deposited as weld overlays onto steel substrates.
Wear resistance of these alloys is due to their microstructure, which comprises hard rod like carbides dispersed in a matrix of austenite or martensite.
The microstructure and carbide morphologies of these alloys can vary significantly depending on the chemical composition and the production
Blow Bars for Impact Crushers Structure and characteristics:
The impact crusher hammer is made of modified high manganese steel, ultra high manganese steel, and ultra high chromium cast iron. After composite treatment, the grains are refined and the grain boundaries are purified; the solidification method is controlled in the casting, and the heat treatment process is optimized. With high hardness, good toughness, high impact resistance and strong wear resistance, it is suitable for the work needs of various types of impact crushers.
1. The use of double refining technology outside the furnace effectively reduces the hazards of harmful elements, inclusions, oxygen and hydrogen, and greatly improves the wear resistance and impact toughness of steel !
2. The patented modifier is used for modification to refine the crystal grains, improve the morphology and distribution of carbides, and further improve the wear resistance and toughness.
3. Optimized heat treatment process makes the product uniform in hardness and stronger in impact and wear resistance.
4. According to the statistical data of thousands of industrial and mining enterprises, the amount of high chromium hammer crushed stone reaches 30,000 to 40,000 cubic meters, which creates huge economic benefits for users.Technical Parameters:
Heat treatment process and equipmentProcess: high manganese steel water toughening heat treatment, high chromium quenching and tempering heat treatment process
Heat treatment equipment: automatic temperature control resistance furnace
Testing and equipment chemical composition:
1. Direct reading spectrometer2. Chemical analysis
