Abstract

The invention discloses a preparation method of a wear-resistant high-temperature-resistant casting material, belonging to the technical field of refractory materials. The preparation method comprises the following steps: by using alumina ceramic product waste with different grain sizes as a main material, waste dust with different grain sizes collected in a high-temperature alumina powder production process as an auxiliary material, calcium aluminate cement as a binder, silicon micropowder and active alpha-Al2O3 micropowder as reinforcers, and dry powder high efficiency water reducing agent, sodium tripolyphosphate and sodium hexametaphosphate as compound additives, filling into a strong stirrer, stirring for 10-20 minutes until the materials are evenly mixed, and bagging. By using production waste as the main raw material, the wear-resistant high-temperature-resistant casting material has the advantages of low price, low use cost, high density, high strength, small linear variation after firing, excellent wear resistance, excellent scour resistance, excellent corrosion resistance, high temperature resistance, favorable high-temperature stability and long service life.

Description

technical field [0001] The invention relates to a method for preparing a wear-resistant and high-temperature resistant castable, which belongs to the technical field of refractory materials. Background technique [0002] Wastes are unavoidable in the ceramic production process, mainly including body waste, waste glaze, firing waste, grinding and polishing waste, and dust collection waste. These wastes pollute the environment and affect the sustainable development of the ceramic industry. Among them, the firing waste is hard, insoluble, and non-degradable, and its disposal has become a difficult problem in the ceramic industry. Even if it is ground into powder, the reuse rate in the formula is only about 5%, and the ceramic factory itself cannot digest these ceramic waste. At present, there are plastic fillers (CN201010504968.X), permeable bricks (CN200610124386.2), burn-free bricks (CN201010616959.X), concrete blocks (CN200810027113.5), spray coatings (CN200910060473.X) pro...
