Abstract

The invention relates to a refractory material, in particular to a mending material of a glass furnace. The mending material of the glass furnace is prepared from the following raw materials in parts by mass in proportion: 12 to 23 parts of zirconite with a grain size of 0.5mm to 0.25mm, 21 to 40 parts of zirconite with a grain size of 0.25mm to 0.15mm, 12 to 22 parts of zirconite with a grain size of 0.15mm to 0.07mm, 5 to 10 parts of zirconite with a grain size of 0.07mm to 0.05mm, 10 to 15 parts of silicon carbide, 5 to 16 parts of silica sol, 9 to 13 parts of aluminum dihydrogen phosphate and 0.7 to 1 part of low-calcium aluminate cement. The mending material of the glass furnace is obtained through material mixing and ball milling. According to the mending material of the glass furnace, which is provided by the invention, the zirconite is extremely low in heat conductivity coefficient; the mending is carried out in a high-temperature furnace for glass; the thermal scouring resistance is good; the peeling off is difficult.

Description

technical field [0001] The invention relates to a refractory material, in particular to a glass kiln repair material. Background technique [0002] Since the glass furnace has been operating at high temperature, the inner wall is subjected to large scouring force, and the surface layer is easily peeled off. After a long time, the furnace wall is damaged and needs to be repaired. Commonly used repair materials have low erosion resistance, and the repair time cannot last. Contents of the invention [0003] Aiming at the above-mentioned technical problems, the present invention provides a glass kiln repair material with long-lasting repair, and the specific technical solution is: [0004] Glass kiln repair material, prepared from the following raw materials according to the ratio of parts by mass, 12-23 parts of zircon with a particle size of 0.5mm-0.25mm, 21-40 parts of zircon with a particle size of 0.25mm-0.15mm, and a particle size of 0.15 mm-0.07mm zircon 12-22 parts, ...
