As one kind of compound refractories, it make magnesite good slag erosion risistance and graphite high thermal conductivity and low dilatability mixed together. Thus BOF Brick has features of high refractoriness, good thermal shock resistance,erosion resistance, and has good performance in I&S industry, including BOF, EAF, LF. basic refractory brick series have the advantages of good performance, long life and low cost. And long supply experience can make sure that we can give our customer total solutions Alumina Magnesia Carbon brick has same production process, the main raw materials are fused alumina or bauxite, so it has better strength and refractoriness under load, but the slag resistance is not as good as magnesia Carbon bricks.
Andalusite is a superior high-alumina refractory material, with high temperature stability, chemical resistance, heat resistance, strong impact resistance, high thermal mechanical strength characteristics. The color of andalusite is gray, pink and red-brown. Heating to 1300, Andalusite will turn into mullite, which is one of the raw materials to produce advanced refractories.
Magnesia chrome brick is an alkaline refractory product, which is made of periclase and magnesia chrome spinel, and is fired at 1600~1800 °C in an oxidizing atmosphere. It can also be made into non-burned brick by chemical bonding agent such as water glass. According to the raw materials and process characteristics of the products, it can be divided into silicate-bonded magnesia-chrome bricks, direct-bonded magnesia-chromium bricks, re-combined magnesia-chrome bricks, semi-recombined magnesia-chrome bricks, pre-reacted magnesia-chrome bricks Casting magnesia chrome bricks.
With the breakthrough of the suspension preheating and pre-decomposition technology in the cement industry and the increasing size of the equipment, the heat load of the kiln is significantly increased, the rotation speed is accelerated, the alkali corrosion is severe, and the lining life and equipment operation cycle are shortened, thus the requirements for refractory materials. More demanding. Its performance advantages are mainly manifested in: 1. High refractoriness under load and excellent high temperature resistance; 2. High strength, abrasion resistance, and easy to peel off and erosion; 3. Low thermal conductivity and good heat insulation effect; 4. Strong flexibility and heat resistance Excellent seismic performance; 5, moderate density, reduce the cylinder load.
