Quick-drying explosion-proof high-strength wear-resistant castable

Abstract

The invention discloses a quick-drying explosion-proof high-strength wear-resistant castable which comprises the following components in percentage by weight: 24-30% of GL-85 bauxite of 5-3 mm, 20-24%of GL-85 bauxite of 3 to 1mm, 8-12% of GL-85 bauxite of 1 to 0mm, 8-12% of 90 black silicon carbide of 1-0mm, 6-10% of 90 black silicon carbide of less than or equal to 0.088 mm, 15-20% of 93 brown fused alumina powder of less than or equal to 0.088 mm, 2-6% of 92 silica powder, 4-6% of alpha-Al2O3 micro powder, 4-7% of aluminate cement, 1.0-1.5% of steel fiber of 3-5 mm, 0.06%-0.10% of a composite explosion-proof agent, and 0.20-0.40% of a composite additive. According to the invention, 85 bauxite and silicon carbide are used as main materials, and superfine powder is used for combination, so that reasonable grain composition is determined, and on the premise of ensuring wear resistance, densest accumulation, good flowability and convenience in construction are achieved. Meanwhile, the metal aluminum powder and the explosion-proof fibers are added as a composite explosion-proof agent, so that burst during baking is effectively avoided, and the use safety and reliability are greatly enhanced.

Description

technical field [0001] The invention relates to the field of refractory materials, in particular to a fast-drying explosion-proof high-strength wear-resistant castable. Background technique [0002] High-strength wear-resistant castables are mainly used in high-temperature furnaces and pipelines in non-ferrous metallurgy, cement kilns and other related industries. These parts have complex structures and harsh environments, requiring castables to have good erosion resistance, wear resistance, and corrosion resistance; at the same time, Because the construction site generally requires a short construction period, the castables need to be quick-drying, burst-resistant and have good structural strength, but most of the existing high-strength wear-resistant castables cannot meet these characteristics at the same time. Contents of the invention [0003] The object of the present invention is to provide a fast-drying explosion-proof high-strength wear-resistant castable against t...
