Description
Technical Field
The utility model relates to an external refining furnace lining is with anti-oxidant almag carbon brick belongs to metallurgical material technical field.
Background
The furnace external refining process in the modern metallurgical industry puts higher requirements on refractory materials for ladle linings, and can resist the high temperature and vacuum action under the furnace external refining condition; secondly, the porosity is low, the volume density is large, and the organization structure is compact so as to reduce the penetration of slag; and finally, the steel slag composite material has high strength and is wear-resistant and capable of resisting the scouring and wear of the steel slag. The main components A12O3 of the alumina-magnesia carbon brick and MgO can react to generate alumina-magnesia spinel, and the lining structure becomes compact along with volume expansion. Slag resistance and expansion of the alundum brick improve with the increase of MgO content. Si powder, Al powder and SiC powder are properly added into the ingredients, resin is used as a bonding agent, high-pressure forming is carried out, and the materials can be used after being treated at the temperature of 200-300 ℃, so that the oxidation resistance of the materials is improved. However, the use of the above additives is highly likely to cause a sealing layer of SiO2 due to the uneven distribution, resulting in a decrease in the performance of the alumina-magnesia carbon brick.
