Кирпич для снижения Металлический магний furance

Rotary kiln inner lining will be scoured by the hot materials in the kiln and corroded by the dust air, and also need good heat preservation behavior. Through many years’ research with great concentration, our company has developed successfully hi-strength compound prefabricated brick. It has hi-strength wearing layer of good corrosion resistance, and light-weight layer of good heat preservation, assuring the increase of heating efficiency in the kiln. In addition, we have unique design in the brick shape and masonry mode, assuring the integral performance of the inner lining. Through the application in many pelletizing plants, various magnetizing roasting rotary kilns for activated grammite, roasting refinery coke, titanium pigment and siderite, the product has gained good effects and its life can reach more than two years, which can enhance the economic effect, save repair cost, and have won affirmation and praises of users.
