Abstract
The invention discloses a high-temperature-resistant and wear-resistant mud. The raw material components are: fused white corundum, fused aluminum-rich spinel, plate-shaped corundum, supercritical dry nano-silicon powder, and industrial chromium oxide; The combination of several materials controls the hydration rate through aluminum-rich spinel, adjusts the construction time, and uses supercritical dry nano-silica powder to hydrate to form a gel, which produces strength and wear resistance, and provides high strength under the premise of ensuring the hardness of the material. and suitable construction time, the high-temperature and wear-resistant mud of the present invention has fast hardening and high-strength wear resistance, and can replace traditional refractory mud for high-temperature and severe erosion parts. It is easy to use and can greatly extend the life of wear-resistant materials , significant economic and social benefits.
Description
technical field [0001] The invention relates to the technical field of wear-resistant mud for grinding equipment, in particular to a high-temperature-resistant wear-resistant mud. Background technique [0002] During the use of mechanical equipment, wear is an important reason for equipment damage, especially in modern grinding equipment, the wear of the air supply pipe is very serious, resulting in frequent shutdowns for overhaul and replacement of lining materials, which restricts the service life and use of equipment benefit. In order to improve the service life of the air supply duct, the method currently adopted is to paste alumina ceramic sheets or cast and smear wear-resistant ceramic materials. Resin materials are usually used as adhesives for pasting ceramic sheets. Due to the high-temperature aging and pulverization of polymer materials, alumina ceramic sheets will fall off in large areas. High-hardness ceramic sheets will increase the wear of downstream pipelines...
