Description

Sand mould adhesive heating device

Technical Field

The utility model relates to a heating device field especially relates to a sand mould adhesive heating device.

Background

The production sequence of the zirconia corundum fused brick which is the main material for building the glass kiln is as follows: the zircon sand, the alumina powder and the soda ash are mixed and added into an electric arc furnace for high-temperature melting, when the feed liquid meets certain requirements, the feed liquid is cast into a cavity of a sand mold, and the blank brick of the fused zirconia-corundum brick is obtained after about ten days of heat preservation and annealing. The manufacturing of the sand mold is a key link, the sand mold is made of silica sand serving as a main material, the modified water glass serves as an adhesive, and the organic grease serves as a self-hardening curing agent of the modified water glass sand mold. The sand mold production mode is the inorganic adhesive which has the highest efficiency and meets the environmental protection requirement at present and is also the adhesive with the lowest cost. The viscosity of the modified water glass is greatly changed along with the change of the environmental temperature, the viscosity is low in spring, autumn and summer when the temperature is 15-25 ℃, the use is convenient, and the water glass can be added into sand to be effectively mixed according to the required amount through a gear pump. When the temperature is about 0 ℃ in winter, the viscosity of the modified water glass is high, the gear pump cannot be effectively added according to the required proportion, so that the quality of the sand mold cannot be ensured, and the modified water glass needs to be heated to about 30 ℃.
