Abstract

A water-cooled furnace cover edge area castable comprises 22-40 parts of bauxite, 15-22 parts of corundum aggregates, 10-18 parts of zircon, 7-15 parts of fine corundum powder, 8-12 parts of silicon carbide, 14-23 parts of mullite, 18-26 parts of magnesia, 2-5 parts of boron nitride powder, 3-5 parts of fused magnesia powder, 3-6 parts of chromium oxide powder, 4-8 parts of aluminum oxide micro-powder, 0.1-0.3 part of explosion-proof fibers and 0.12-0.22 part of sodium hexametaphosphate. A scientific and reasonable material ratio is adopted to well balance the strength, the wear resistance andthe corrosion resistance of the castable, so the castable has excellent comprehensive performances, and the disadvantages of easy corrosion and wearing, difficult sintering, easy shedding and short service life of water-cooled furnace cover edge area castables are effectively overcome.

Description

technical field [0001] The invention belongs to the related technical field of refractory materials, and in particular relates to a castable for the edge area of ​​a water-cooled furnace cover. Background technique [0002] The castable in the edge area of ​​the water-cooled furnace cover is mainly used in the water-cooled furnace to shield the steel slag splashed by the molten steel in a vacuum environment, and to protect the water-cooled furnace accordingly. The currently widely used castables in the edge area of ​​the water-cooled furnace cover have a relatively low corrosion rate against steel slag due to the material and process technology itself, and the castables are difficult to sinter and often fall off during use, resulting in a short service life. And now many related companies have higher requirements for castables, which makes related supply companies have greater requirements for castables in the edge area of ​​​​the water-cooled furnace cover.
