la composición química de la bauxita es principalmente al2o3, sio2, fe2o3, TO2, y representa alrededor del 95% de la composición total, y los componentes secundarios son cao, mgo, K2O, na20, S, mno2 materia orgánica y componentes traza ga, ge, etc.
In recent years, bauxite powder and bauxite have been widely used in common cast steel coatings and cast iron coatings due to their high fire resistance, good chemical stability, small expansion coefficient, rich source and low price.
Los carros refractarios para cucharones están hechos de corindón fundido de alta pureza como material principal, Se agrega espinela de alta pureza a la matriz, y se agrega una cantidad adecuada de aglutinante y mezcla (dispersante, agente reductor de agua) .
El ladrillo con alto contenido de alúmina es uno de los materiales refractarios básicos indispensables en las partes superior y media del cuerpo del alto horno en la industria del hierro y el acero.
High alumina brick is mainly used for lining of blast furnace, hot blast furnace, electric furnace roof, reverberatory furnace and rotary kiln. In addition, high alumina brick also widely used as open hearth regenerative lattice brick, pouring system with plug,such as nozzle brick.
<p>Los ladrillos con alto contenido de alúmina se utilizan principalmente en el regenerador de la estufa de aire caliente. Los ladrillos de celosía con cierta estructura están dispuestos de manera ordenada, y los orificios pasantes superior e inferior de los ladrillos de celosía pueden permitir que pase el gas.</p>
Refractory ramming mass (refractory taphole mass) is a kind of Refractory used for lining of blast furnace tapping groove. It is mainly used to protect the blast furnace out of the ditch from high-temperature hot metal and slag erosion and erosion, and has excellent high-temperature resistance and wear resistance. The ramming material for the iron discharge ditch is usually composed of corundum, silicon carbide and carbonaceous material, which has the ability of resisting hot metal and molten slag erosion and scouring, reburning line change small, strong resistance to a variety of oxidation characteristics. The construction of the ramming material for the iron ditch is convenient, easy to dismantle and repair, does not produce harmful gas, and is beneficial to environmental protection.
