Abstract

The invention discloses a seepage and corrosion resistant casting material. The casting material comprises an A composition, a B composition and a C composition, wherein the weight percentage of various compositions is calculated by the 100 total weight percentage of the casting material; the A composition is a uniform mixture of the following compositions: 13 to 18 percent of 5-7 mm fused zirconcorundum, 12 to 20 percent of 3-5 mm fused zircon corundum, 19 to 27 percent of 1-3 mm fused zircon corundum and 12 to 18 percent of 0-1 mm fused zircon corundum; the B composition is a uniform mixture of the following compositions: 3 to 5 percent of activated alumina micro powder, 2 to 4 percent of low-iron silica fume, 3 to 7 percent of desilicate zirconium, 2 to 10 percent of zircon powder and 2 to 10 percent of white alundum powder; and the C composition is a uniform mixture of the following compositions: 1 to 3 percent of alumina cement and 0.05 to 0.15 percent of sodium tripolyphosphate. The seepage and corrosion resistant casting material has the advantage of strong capacity of resisting corrosion of glass chemistry and the like.

Description

technical field [0001] The invention relates to an anti-seepage and anti-corrosion castable, in particular to an anti-seepage and anti-corrosion sealing integral inner lining material for a glass kiln, which can also be used as a material for emergency repair and plugging of a glass kiln. Background technique [0002] The melting part, end wall and bottom of the glass furnace in my country are eroded and scoured by the high-temperature glass liquid phase, the refractory ramming material is seriously damaged, and the integrity of the refractory ramming material is not strong, it is easy to leak, and the bottom of the glass furnace is sintered and laid Brick construction requires high requirements, pre-arranged numbers and poor sealing effect of brick joints, so the overall lining of glass kiln is the development direction of glass melting technology. At the present stage, the research on the overall lining of glass furnaces in this field is generally still in the research and ...
