Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the manufacturing quality of existing traditional products (castables) is difficult to guarantee, and the on-site construction period is long. However, under the influence of different external factors, it is very easy to crust and even cause material blocking, and the comprehensive use effect is poor. , is greatly affected by environmental human factors, so as to provide anti-skinning prefabricated parts and production methods

Abstract

The invention relates to an anti-skinning prefabricated part and a production method thereof. The anti-skinning prefabricated part is produced by subjecting, by weight, 50-75% of alumina, 10-15% of silicon carbide, 1-5% of high aluminum fine powder, 5-7% of carborundum fine powder, 1-3% of zirconia fine powder, 1-3% of graphite fine powder, 5-8% of alumina fine powder, 1-3% of silicon micropowder, 1-5% of antioxidant, 0-0.5% of bonding agent and 0-0.5% of water reducing agent to production procedures including stirring, binding, pressing, roasting, calcining, cooling, drawing, packaging and the like. The anti-skinning prefabricated part and the production method thereof have the advantages that by means of reasonable collocation of compositions and effective production process, high temperature resistance is improved, stability and corrosion resistance of a product are improved, the anti-skinning performance of the product at the position of the anti-skinning prefabricated part is improved, and accordingly longer service life, short production period and effectiveness in use are achieved.

Description

technical field [0001] The invention relates to an anti-skinning preform and a production method. Background technique [0002] Anti-skinning special prefabricated parts are mainly used in the field of new dry process cement rotary kiln, which solves the key problems such as skinning caused by various factors in some specific parts of the original material (castable) and indirect skinning and blocking caused by easy hanging materials. Problem, there are no strict requirements on the ratio of existing materials (castables), the level of raw materials used is relatively low, the manufacturing cost is not uniform, the product quality is unstable, the construction period is long, and it is easy to be washed out, crusted, blocked Material, corrosion and wear, the comprehensive use effect is poor. Contents of the invention [0003] The technical problem to be solved by the present invention is that the manufacturing quality of existing traditional products (castables) is diffic...
