Problems solved by technology

[0002] In recent years, with the introduction and continuous enlargement of the cement precalcining kiln, the core equipment in the cement industry, the production capacity of the kiln system has been continuously improved. Due to the continuous improvement of the kiln speed and the increase of the load in the kiln, the performance of refractory materials has also been continuously improved. Putting forward new requirements, especially the working environment at the kiln mouth and the bend area of ​​the tertiary air duct is very harsh. Due to the low explosion-proof performance of the currently used refractory materials, the general life span is only 3-5 months, which affects the performance of the cement kiln.

Abstract

The invention relates to a castable, and concretely discloses a high-hardness castable. Raw materials of the castable comprise, by weight, 40-58 parts of spinel, 12-23 parts of mullite, 10-21 parts ofalumina micro-powder, 3-10 parts of an explosion-proof agent, 5-13 parts of cement, 3-11 parts of trichromium dicarbide powder, 5-12 parts of composite gel powder, 2-6.5 parts of rock wool, 2-4.5 parts of a dispersant, 1-3 parts of a plasticizer and 1-3 parts of water glass. The high-hardness castable has excellent explosion-proof performance.

Description

technical field [0001] The invention relates to castables, in particular to a high-hardness castable. Background technique [0002] In recent years, with the introduction and continuous enlargement of the cement precalcining kiln, the core equipment in the cement industry, the production capacity of the kiln system has been continuously improved. Due to the continuous improvement of the kiln speed and the increase of the load in the kiln, the performance of refractory materials has also been continuously improved. Putting forward new requirements, especially the working environment at the kiln mouth and the bend area of ​​the tertiary air duct is very harsh. Due to the low explosion-proof performance of the currently used refractory materials, the general life span is only 3-5 months, which affects the performance of the cement kiln. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a castable wi...
