Patent No.: CN200610015089.4, a coating that prevents coal slag from coking on the heating surface.
A coating that prevents coal slag from coking on the heating surface. Take 25kg of zirconium dioxide, three 14kg of aluminum oxide, 18kg of magnesium oxide, 4kg of lithium fluorosilicate, 5kg of manganese powder, 1kg of cerium oxide, 1kg of cobalt oxide, 30kg of sodium silicate, 15kg of potassium silicate, 1kg of magnesium hexametaphosphate, 3kg of aluminum hexametaphosphate. The above powder is obtained by ball milling, sieving, and then mixing and stirring evenly.
The invention has the following advantages: simple construction, convenient use, excellent high temperature and chemical stability, and extremely strong resistance to coking, media erosion, and high temperature corrosion. Improve the adhesion between coating and metal at high temperatures.
Slag is also called molten slag. The melt generated during the pyrometallurgical process and floating on the surface of liquid substances such as metals is mainly composed of oxides (silica, alumina, calcium oxide, magnesium oxide), and often contains sulfides with a small amount of metal.
