Silicon mullite red brick for large cement kiln and its producing method

Abstract

The present invention is silicon mullite red brick for large cement kiln and belongs to the field of refractory material technology. The silicon mullite red brick is made with alum as aggregate, silicon carbide, electrocast white alundum powder, andalusite powder, clay, yellow dextrin, methyl cellulose and water, and through mixing, pressing and sintering. Practical application in large cement kiln shows that the silicon mullite red brick has high heat insulating effect and long service life.

Description

technical field

[0001] The invention belongs to the field of refractory materials, in particular to a silica molybdenum brick for large-scale cement kilns, and at the same time provides a manufacturing method of the silica molybdenum brick. Background technique

[0002] With the continuous update of cement production technology, the main equipment of cement production has been developed to be large-scale. Increasing output, improving quality and saving energy consumption have become the key to increasing efficiency in production management. In the cooling section, transition section, kiln mouth and other parts of the large cement kiln chamber, ordinary refractory bricks can no longer meet the requirements. At present, most of the large cement kilns use imported spinel, but its cost is high and its service life is not long. It can only last about 5-6 months. Contents of the invention

[0003] The invention provides a low-cost domestically produced large-scale cement kiln s...
