In terms of manufacturing process (taking high manganese steel as an example):
1. Material selection: Select high manganese steel materials such as zgmn13. High manganese steel has high wear resistance and impact toughness.
2. Casting process: Usually advanced sodium silicate molding or lost foam casting process is adopted to ensure a smooth product surface and a uniform internal structure.
3. Composition control: High manganese steel contains alloy elements such as manganese, chromium, nickel, and molybdenum. Among them, the manganese content is generally between 11.0% and 14.0%, and the specific content varies according to the grade and usage requirements.
4. Heat treatment: This is a key step. Heat to 1100°C for insulation and then take it out of the furnace. After chemical treatment with alloy quenching liquid (which can greatly increase the hardness), then temper at a low temperature of 600°C and take it out of the furnace and air cool. After such a heat treatment process, the hardness can reach more than 60HRC. By refining the grains, it can have high wear resistance and high impact toughness.
The arm guard plate of the jaw crusher, also known as the side guard plate, is an important part of the jaw crusher.
Detailed introduction:
It is located between the fixed tooth plate and the movable tooth plate and mainly plays the role of protecting the frame wall of the equipment and preventing the wear and impact of materials on the frame during the working process of the crusher.

In actual production, the manufacturing process of the arm guard plate may vary depending on the manufacturer, equipment conditions and specific requirements. At the same time, in order to prolong the service life of the arm guard plate, it is also necessary to pay attention to the correct use and maintenance of the jaw crusher, such as controlling the feeding particle size and avoiding overload operation.
If you need the detailed manufacturing process of a specific model or manufacturer's arm guard plate, it is recommended to directly contact the relevant manufacturer to obtain more accurate information.
