Abstract

An erosion-resistant high-temperature refractory brick for waste liquid incineration includes the following materials by the weight percentage: 10-35% of 5 mm-3 mm tabular corundum particles, 20-98% of 3 mm-1 mm tabular corundum particles, 5-25% of 1 mm-0 mm tabular corundum particles, 20-98% of 320 mesh tabular corundum powder, 5-30% of 80 mesh zirconia, 2-15% of chromium oxide green and 2-13% ofhigh temperature alpha-alumina micro-powder. The erosion-resistant high-temperature refractory brick has the advantages of high load softening temperature, good thermal shock resistance, high corrosion resistance at room temperature and high temperature, good wear resistance, good thermal conductivity, and excellent resistance to waste liquid erosion, and is especially suitable for solution molten slag corrosion invasion of a high temperature melting furnace.

Description

technical field [0001] The invention belongs to the related technical field of refractory materials, and in particular relates to an anti-corrosion high-temperature refractory brick specially used for waste liquid incineration and a preparation method thereof. Background technique [0002] Refractory brick is a kind of building material brick, and its property is "refractory" like its name. It is a refractory material fired from refractory clay or other refractory raw materials, which can withstand various physical and chemical changes and mechanical actions at high temperatures. Refractory bricks are not common in our lives, but they appear in some buildings that are closely related to our lives, such as housing construction, kiln construction, thermal equipment, etc. [0003] According to the current national requirements for environmental protection, the production of organic chemicals such as resin products requires environmentally friendly treatment of waste materials....
