We will make timely and reasonable adjustments to the competitive strategy according to the implementation progress and evaluation results to ensure the complete realization of the entire enterprise goal.
1,Description of High Alumina Brick for Blast Furnace:
The bauxite calcined in high density rotary kiln is used as the main raw material. It is shapped by a brick machine of more than 630 tons and sintered at high temperature from 1460℃-1480℃.The density of the product is over 2.65g/cm3 and the porosity is less than 19%. The products are widely used in blast furnace and other high temperature industrial furnaces due to their good corrosion resistance, high density, high temperature resistance, good slag corrosion resistance and low change rate of reburning line.

3,Product characteristics:
(1).The production technology of high alumina bricks has been improved. High density bauxite calcined in rotary kiln has been used and large tonnage moulding machine has been used to increase sintering temperature, The density of products has been increased from≥2.5g/cm3 to ≥2.65g/cm3, and the porosity has been reduced from≤24% to≤19%.Thus, the compactness of products has been greatly improved and the slag corrosion resistance of products has been improved,the application effect of blast furnace and other industrial furnaces is excellent.
(2).The product is light yellow with smooth surface, strong compactness and neat edges and corners.
(3),The products can be divided into lattice bricks for regenerator and straight bricks for wall, which can resist high temperature and flue gas corrosion well.
(4),The main crystalline phases of the product are corundum phase and mullite phase, which have low creep rate and low linear change rate at high temperature. That is to say, the product has stable performance at high temperature.
(5),Our company has been producing and supplying this product for more than ten years. We strictly control the product quality assurance system and provide high-quality products and good services for users.
