The influence of metallurgical compound and mechanical compound on high chromium wear-resistant hammer

Hammer heads are key parts and vulnerable parts of hammer crushers in construction materials, mining, chemical and other industries. Traditional hammers are mostly cast with high manganese steel, and use the work hardening characteristics of high manganese steel under impact load to improve wear resistance, but its wear resistance is far from suitable for low-consumption modern production requirements.

Due to the short life of the hammer head and frequent shutdown and replacement, which reduces the operation rate of the equipment, it is necessary to find a new material and new technology to improve the performance and service life of the hammer head.

High-chromium wear-resistant hammer head The hammer handle is made of a material with good toughness, and the hammer end is made of a material with good wear resistance, and a certain production process is used to organically combine the two, so that the hammer can meet the requirements of toughness and wear resistance at the same time .

Generally, the bimetal composite hammer head refers to the choice of two alloys for the hammer handle and the hammer head. Choose a hammer head with impact toughness for the hammer handle, and choose a hammer head with high hardness for the hammer head. However, there are two ways to combine the hammer handle and hammer head. Mechanical mixing is also called cold mixing. The other is metallurgical bonding. In the casting process, two-liquid composite casting is selected at the same time. The choice of bimetal hammer head is * two-component composite hammer head, because the hammer head and hammer handle will not break.
Withstand strong impact, especially when the material is broken and the feed is large, the mechanical compound hammer usually first casts the hammer handle, and then pours the hammer head high chromium molten iron to wrap the hammer handle, but the interior is still not metallurgical.
The compound is easy to break during the heat treatment, and the hammer head is also easy to turn and be damaged when damaged.
