Application of heating furnaces Refractory insulation coating to prevent cracking of heating furnace refractory materials. Heating furnaces are used in petroleum, chemical, metallurgical, mechanical, building materials and other industries. Heating furnaces are essential equipment in the process of oil field development. Types of refractory materials Refractory insulation coating to prevent cracking of heating furnace refractory […]

Refractory materials are classified into neutral, alkaline and acidic. Whether it is refractory bricks or refractory castables, these three properties are also used to distinguish them. Neutral refractory materials are composed of alumina or carbon. Products include high-alumina, corundum, and carbon refractory bricks and castables. Acidic refractory materials are composed of silicon oxide. Products include

Slide gate plate plays an important role in the ladle system, and it is very important to improve service life of ladle slide gate. Learn methods to increase service life of ladle slide gate and the functions of ladle slide gate. Slide gate plate is the most important part among the slide gate nozzle system,

(1) Refractories for ARC furnace roof Electric Arc Furnace life refers to the life of furnace roof. After the 1980s, with the expansion of steel-making electric arc furnace capacity and the increase of unit power, the working conditions of the furnace roof become more demanding, the refractories used for electric Arc furnace also changed. The

In the ladle, due to the complex physical and chemical environment at the slag line, the furnace lining at this part is most vulnerable to damage. The chemical attack of slag on magnesia-carbon bricks is mainly through the dissolution of magnesia and the oxidation of carbon in the matrix of magnesia-carbon bricks, and the damage of
