Abstract

A high-temperature economizing abrasive coating, its use and production are disclosed. The process is carried out by mixing nanometer alumina with titanium carbide, silicon oxide and iron oxide, ball grinding, mixing with high-temperature adhesive, agitating, blending and milling to be pasted The coating consists of abrasive agent 13-18 proportion, blackening agent 15-18 proportion, preserving agent 10 proportion, binder 45-55 proportion and additive 7 proportion. It's fine and dense; it has better binding strength and abrasive performances and no bubble. It can be used for internal wall of boiler in coal-fired power plant, pipeline and metallurgical industry with temperature above 1200 deg. C.

Description

technical field [0001] The invention relates to the production technology of high-temperature energy-saving and wear-resistant coatings, in particular to an energy-saving and wear-resistant coating for metal surfaces of power plant boilers and a production method thereof. Background technique [0002] Energy conservation and consumption reduction are advocated everywhere nowadays, especially for large industrial energy-consuming households, and energy conservation has become imperative. Wear and corrosion has always been a major problem that plagues the safe operation of power plants. The power generation provided by such boiler plants is estimated to account for more than 83% of the country's total power generation. Due to the high temperature and high pressure of the power plant boiler, the "four tubes" have seriously affected the normal operation of the power plant due to the troublesome tube explosion. According to incomplete statistics in 2006, the direct loss caused b...
