Abstract

The invention discloses a coal injection pipe prefabricated member recipe which comprises the following integrities in percentage by weight: 75 to 85 percent of calcium hexaluminate, 5 to 15 percent of silicon carbide, 5 to 10 percent of aluminate cement, trimeric sodium phosphate and 0 to 2 percent of composite additives formed by methylcellulose. The prefabricated member product made by the recipe in the invention can solve the problems of antistripping, wear resistance and the like in the use process.

Description

technical field [0001] The invention relates to a formula of a coal injection pipe prefabricated part. Background technique [0002] Traditional monolithic refractory materials are usually poured and formed at the site of use. The construction period is long, the labor intensity is high, and the maintenance time is long to ensure a certain service life. Prefabricated parts refer to the oversized and special prefabricated products of different shapes produced by changing the supply of the original bagged castables to complete the pouring, curing and heat treatment processes in the factory in advance. The development of this kind of products has completely solved the traditional On-site construction weaknesses of monolithic refractories. However, the formulation of the existing prefabricated products is difficult to meet the problems of anti-burst, peeling, wear and the like of the prefabricated parts during use. Contents of the invention [0003] The technical problem to ...
