Counterattack break adjustment plate, counterattack frame backing plate
Medium manganese steel (Mn8), high manganese steel (Mn13-2, Mn13-3, Mn13Gr2), wear-resistant alloy steel
Lost foam, quartz sand sand casting, resin sand sand casting
Suitable for industrial sectors such as metallurgy, mining, cement, chemical industry, refractory materials and ceramics, as well as highway and water conservancy construction
1. Special composite casting process. The parts produced by our company are made of high-chromium alloy materials, and the hammer handle parts are made of low-alloy steel materials with better toughness. The high-chromium alloy hammer head uses thermal compounding to combine two materials with different properties and functions in the liquid. In the state, it can be melted into one body, and the composite area can reach 100%, which completely solves the problems of fracture, block loss, and U-turn that are prone to inlaid alloy and double composite casting, and improves the safety of use.
2. Special heat treatment process. The heat treatment process is to heat to 950-1000℃, keep warm, and then out of the furnace. After cooling by our company's mist quenching device, the price of a low temperature tempering hammer head of 200-260℃ is carried out. The final out-of-furnace air cooling hardness can reach 62HRC. --65HRC.
3. Strict production management and quality control. The products used by our company have strict production process and quality control. The composite hammerhead of the crusher is tested in front of the furnace, and the content of each element of the sample is analyzed by the multi-channel spectrometer; the casting and quality control are strictly controlled. Heat treatment temperature; use flaw detector to detect internal pumping holes and blisters, etc.; use hardness tester to test hardness.
4. Low price and good economic benefits. The service life of high chromium alloy hammers is 4 times that of forging or high manganese steel, but the price is twice that, which meets the demand for high replacement frequency of small sand and gravel production lines. Wear-resistant hammers have Very strong economic benefits.
5. To provide humanized services can be customized according to drawings. If there are no drawings, our company has professional surveying and mapping personnel to help you customize after surveying and mapping. The counterattack hammer produced by our company is cast with high chromium materials. Compared with ordinary high manganese steel hammers, the price of the hammer has the characteristics of high hardness and wear resistance. Counterattack the high-hardness martensite matrix in the plate hammer to support the carbide particles strongly. The composite hammerhead of the crusher prevents the carbide from falling off the worn surface during the working process, ensuring the high abrasion resistance of the material, and the hardness can reach 62HRC- -65HRC. Product features The counterattack hammer is used in cement, refractory, metallurgy, stone and other industries. It is widely used in granite, basalt, limestone, river pebble, high-chromium alloy hammer-head quartz stone, iron ore, bauxite and other minerals The crushing is also suitable for the production of high-quality stones in industries such as machine-made artificial sand, high-grade highways, railways, water conservancy, airports, construction, cement, refractory materials, and wear-resistant hammer metallurgy. Our company has also developed a new type of composite board hammer for the poor working conditions of some domestic cement plants and the serious wear of the counterattack hammer. The hammer has a uniform hardness and stronger impact and abrasion resistance. The hammer price is red apple casting. According to the different industrial and mining conditions of the user, the hammer material makes the product have good wear resistance, impact resistance, and the safety and reliability of the crusher composite hammer. The new composite plate hammer produced by Red Apple Casting has become a major and medium-sized cement plant and mine The main products are sold to high chromium alloy hammers in Inner Mongolia, Shanxi, Shaanxi and other regions, and have achieved good social and economic benefits.
