GX280 (KMTBCr26) High-efficiency mining machinery casing

GX280 (KMTBCr26) high-efficiency mining machinery casing is made of high-quality wear-resistant materials. After precise quenching treatment, the hardness can reach HRC>60, and it can maintain long-term stable operation in the high-intensity environment of mining machinery and powder grinding. The casing is specially designed for mining and grinding operations. It has strong wear resistance and impact resistance, and can effectively withstand the wear caused by ore and grinding materials.

GX280 (KMTBCr26) high-efficiency mining machinery casing adopts wear-resistant steel cast pipe technology to ensure that the casing surface has high wear resistance. The application of wear-resistant steel cast pipe improves the wear resistance of the casing, reduces the maintenance frequency of equipment, and prolongs the service life. The product can maintain stable performance under high temperature, high pressure and harsh working conditions, and adapt to complex mining environments and grinding tasks.

This wear-resistant cast steel pipe is specifically designed for demanding working conditions such as ore transportation, slurry transfer, and tailings discharge in mining operations. It is manufactured using a high-chromium alloy base material with optimized additions of vanadium, niobium, nickel, and other trace elements, and produced through precision casting or centrifugal casting processes.

The core performance features are tailored to mining requirements: the surface hardness reaches HRC62–65, providing a wear life 3–5 times longer than that of ordinary steel pipes, effectively resisting continuous abrasion from solid particles in high-concentration slurry. It also offers excellent impact toughness, capable of withstanding impact loads from rocks up to 25 mm in diameter without cracking or failure. The inner wall is smooth and dense, free of pores, inclusions, and other defects, resulting in low flow resistance, reduced energy consumption during transportation, and enhanced corrosion resistance against acidic and alkaline media, making it suitable for acidic mine wastewater environments.

Available in sizes ranging from DN80 to DN2600, the product supports customization of special components such as reducers, elbows, and conical pipes, and can be installed quickly via flanges or welding. It is widely used in coal, copper, iron, and other mining material-handling systems, significantly reducing downtime for replacement, lowering overall maintenance costs, and serving as a key piece of equipment for efficient and stable mining production
