Abstract

The invention relates to a coating for a non-shrinkage-cavity fusion cast brick heating insulated feeder head. The problems of fusion and bonding of a feeder head and a brick body and low utilization rate of the feeder head can be effectively solved. According to the technical scheme, the coating comprises a ground coating with which the inner surface of the heating insulated feeder head is coated and a surface coating with which the surface of the ground coating is coated. The ground coating is prepared from, by weight, 49-51% of a first composition and 49-51% of water, wherein the first composition is prepared from, by weight, 92-94% of graphite powder, 3.9-4.1% of cryolite, and 2.9-3.1% of bentonite; the surface coating is prepared from, by weight, 65-67% of a second coating, 4.4-4.6% of cryolite, 1.4-1.6% of iron oxide powder, 0.9-1.1% of bentonite and 2.9-3.1% of xanthan gum. The coating is reasonable in formula, effectively solves the problem of the post-casting fusion and bonding phenomenon, greatly recycles feeder head materials, and has the good social and economic benefits.

Description

technical field [0001] The invention relates to a coating, in particular to a coating used for heating and heat preservation risers of non-shrinkage electric fused bricks. Background technique [0002] Zirconium corundum fused bricks have been developed in my country for decades. The raw materials for casting sand molds are mainly silica sand, and water glass or resin is added as binder for the production of sand molds. The high temperature resistance and heat resistance effect of silica sand It is more suitable for the production of fused brick sand molds, coupled with its advantages of abundant resources and low cost, it is still the first choice material for fused brick sand molds. [0003] The service life of the float glass furnace is currently about 8 years on average, and the average service life of the horseshoe flame daily-use glass furnace is about 5 years. The pool wall brick of the glass furnace is a key part of the service life of the glass furnace. From the indu...
