Abstract

The invention relates to the technical field of refractory materials, and discloses a refractory material used for glass kilns. The refractory material used for glass kilns comprises, by weight, 10-15 parts of silica, 1-3 parts of ferriferrous oxide, 1-8 parts of alumina, 1-2 parts of propylene glycol, 3-7 parts of acrylamide, 1-2 parts of aluminum nitride powder, 1-2 parts of yttrium oxide powder, 2-7 parts of barium sulfate, 1-1.5 parts of boron carbide, 0.5-1.5 parts of cerium oxide powder, 10-12 parts of phenolic resin, 6-8 parts of muscovite powder, 1-2 parts of sericite powder, 10-15 parts of polycarbosilane, 2-6 parts of zirconium oxide and 5-6 parts of magnesium oxide. The invention also provides a preparation method of the refractory material for glass kilns. The preparation method comprises the following steps: fully mixing the raw materials of all above components, ageing the raw materials, placing the aged raw materials in an electric furnace, heating the aged raw materials, cooling the heated raw materials, pouring the cooled raw materials into a precast mold, and cooling and annealing the raw materials. The refractory material used for glass kilns has the advantages of high thermal shock resistance, high strength, high toughness, good corrosion resistance and high wear resistance.

Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to a refractory material for a glass kiln. Background technique [0002] Glass is mainly made of quartz sand and soda ash as raw materials through high-temperature melting. Glass furnaces are equipment for melting glass. There are many types of glass furnaces, such as pool furnaces and crucible furnaces. [0003] The current problem is that the glass furnace lining is usually subject to considerable wear and chemical attack, and has the effect of thermal stress, because the molten glass and the raw material of the glass are highly corrosive. In continuous melting furnaces, melting The process usually continues until the furnace is out of service. During this process, the refractory material of the furnace walls is scratched and wear spots are created where they are corroded, and the wear spots grow until the molten glass seeps out. Wear points can seriously affect the...
