Embodiment Construction

[0016] A heat-shock-resistant refractory brick made of the following raw materials (kg): crushed gravel 16, blast furnace slag 18, chromium-containing aluminum silicate fiber 12, volcanic ash 22, sericite 20, potassium silicate 11, sugar factory filter Mud 35, yellow dextrin 8, borax 9, sodium silicate slag 30, flake graphite powder 14, porcelain stone tailings 20, aluminum titanate 12, fiber stone 22.

[0017] A method for preparing a thermal shock-resistant refractory brick, comprising the following steps:

[0018] (1) Mix blast furnace slag, volcanic ash, sericite, sodium silicate slag, and porcelain stone tailings evenly, pulverize them, pass through an 80-mesh sieve, calcinate at 810°C for 3 hours, cool to room temperature, and perform dry ball milling at 400r / min for 25 minutes. Add the ball-milled powder into the hydrochloric acid solution with a mass fraction of 35% at a ratio of 1:4, heat it in a water bath to 65°C, soak it for 6 hours, and filter it when it is natura...

Abstract

The invention discloses a thermal shock resistance refractory brick and a preparation method thereof. The refractory brick is prepared from the following raw materials in parts by weight: 12-19 parts of crushed gravels, 13-22 parts of blast furnace slag, 10-15 parts of alumina-silicatechromere fibers, 18-29 parts of cinerite, 14-26 parts of sericite, 8-14 parts of potassium silicate, 32-38 parts of filter mud of sugar refinery, 5-10 parts of yellow dextrin, 6-12 parts of borax, 24-36 parts of sodium silica slag, 11-17 parts of flake graphite powder, 15-25 parts of china stone tailing, 10-15 parts of aluminum titanate and 16-28 parts of satin stones. According to the refractory brick, alumina-silicatechromere fibers, flake graphite powder, aluminum titanate and other raw materials are mixed, and the advantages of the raw materials are sufficiently utilized to achieve the synergistic effect, so that a higher refractoriness is achieved, and the thermal shock resistance of the refractory brick can be effectively improved. The thermal shock resistance refractory brick has the advantages of good high temperature resistance, excellent thermal shock resistance and long service life.

Description

technical field [0001] The invention relates to a thermal shock-resistant refractory brick and a preparation method thereof, belonging to the field of refractory materials. Background technique [0002] All materials that can resist high temperature and the physical and chemical effects produced at high temperature are collectively called refractory materials. Refractory materials are widely used in various fields of national economy such as metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power, boiler, light industry, electric power, military industry, etc., and are essential materials to ensure the production operation and technological development of the above industries , plays an irreplaceable important role in the development of high temperature industrial production. Refractory materials are generally divided into two types, namely unshaped refractory materials and shaped refractory materials. Among them, shaped refractory materials gene...
