Aluminum-carbon carborundum brick for torpedo ladle and preparation method thereof
The invention discloses an aluminum-carbon carborundum brick for a torpedo ladle and a preparation method thereof. The aluminum-carbon carborundum brick for the torpedo ladle is prepared from, by weight, 62-74 parts of high-alumina bauxite clinker particles, 10-15 parts of high-alumina bauxite powder, 3-6 parts of silicon carbide micro powder, 2-5 parts of crystalline silicon, 10-15 parts of flake graphite and 3-5 parts of thermosetting phenolic resin. According to the method, firstly, the silicon carbide micro powder and the high-alumina bauxite powder are premixed; secondly, other raw materials are sequentially placed into a mixing mill to be mixed and ground, placed in a brick press for molding and heated at the temperature between 150 DEG C and 250 DEG C for 12-36h; finally, sorting, inspection, packaging and warehousing are conducted to obtain the aluminum-carbon carborundum brick for the torpedo ladle. The aluminum-carbon carborundum brick for the torpedo ladle has the advantages of low production cost, good oxidation resistance, good thermal shock resistance, good corrosion resistance performance, long service life and the like, thus can meet the market demand.
