In mining, metallurgy, building materials and other industries, the durability of crusher wear parts directly affects the service life and production efficiency of the equipment. As a high-manganese steel casting manufacturer, China Crusher Wear Parts Factory Through scientific heat treatment processes, the strength, toughness and wear resistance of manganese steel castings are significantly improved to meet the needs of harsh working conditions. This article will detail the heat treatment technology of wear-resistant manganese steel castings and discuss their application in actual production.
Core Objectives of Heat Treatment of Wear-Resistant Manganese Steel Castings
The heat treatment of wear-resistant high-manganese steel castings mainly includes solution treatment, precipitation strengthening and quenching and tempering processes. The core purpose is to eliminate carbide at the grain boundaries in the as-cast structure and obtain a uniform austenite or martensite matrix, thereby improving the comprehensive performance of the material. China Crusher Wear Parts Factory By optimizing heat treatment parameters, ensuring that products have both high impact resistance and wear resistance, becoming an industry benchmark.
Preheat Treatment Process of Crusher Wear Parts
To shorten the production cycle, China's crusher wear parts factories use high-temperature pre-treatment technology: castings are removed from the mold at 1100～1180℃, cleaned and cooled to 900～1000℃, then transferred to a furnace at 1050～1080℃ for heat preservation for 3～5 hours, and then quenched with water. This process can reduce cold working deformation, but the temperature must be precisely controlled to avoid uneven organization.
Precipitation Strengthening Heat Treatment of Crusher Wear Parts
Some high-manganese steel casting manufacturers add carbide-forming elements such as molybdenum, vanadium, and titanium, combined with precipitation strengthening heat treatment, so that the material precipitates dispersed carbide particles, further improving hardness and wear resistance. Although this process is more expensive, it is still used in China Crusher Wear Parts Factory to meet customer needs for ultra-long-life components.
Key Technologies of Solution Heat Treatment of Crusher Wear Parts
There are a large number of carbides in the as-cast structure of high-manganese steel, resulting in insufficient toughness. Through solution treatment (water toughening treatment), the carbides can be fully dissolved to form a single austenite structure. The typical process is heating to 1050～1100℃ for heat preservation followed by rapid water cooling. Low-alloy wear-resistant steel uses 850～950℃ quenching + 200～300℃ tempering to obtain a high-strength and tough martensite structure.
Conclusion
As a professional high-manganese steel casting manufacturer, China Crusher Wear Parts Factory With advanced heat treatment technology, it ensures that each crusher wear part has excellent wear resistance and impact resistance. In the future, with the continuous optimization of the process, the heat treatment technology of crusher wear parts will further promote the industry to develop towards high efficiency and energy saving.
