Abstract

The invention discloses a multiphase ceramic roller. The raw raw materials include aggregate and a binder. The aggregate includes 25-35 parts of a corundum material, 25-35 parts of clay, 18-24 parts of alumina micropowder, 3-6 parts of yttrium oxide, 4-11 parts of titanium dioxide, 3-10 parts of zirconium silicate and 3-6 parts of fine mineral powder. The corundum material includes 7-11 parts of corundum with a particle size of 60-100 meshes, 14-17 parts of corundum with a particle size of 100-200 meshes, and 4-7 parts of corundum with a particle size of 250 meshes and a content of less than or equal to 10%. Accordingly, the invention also discloses a preparation method of the multiphase ceramic roller. The multiphase ceramic roller provided by the invention has the characteristics of highfire resistance degree, good high temperature creep resistance, low thermal expansion coefficient, high service temperature, good thermal shock stability, long service life, etc., and effectively solves the problem of roller bending deformation caused by large temperature gradient in a roller kiln.

Description

technical field [0001] The invention relates to the technical field of ceramic rollers, in particular to a composite ceramic roller and a preparation method thereof. Background technique [0002] Ceramic roller is a kind of refractory kiln furniture. It plays the role of supporting and conveying ceramic bricks and other products in the roller kiln and drying kiln. It is the core component of the roller kiln. It is widely used in architectural ceramics, daily-use ceramics, electronic ceramics, magnetic materials, glass heat treatment and other fields. [0003] At present, the ceramic rollers used in the roller kilns of ceramic production enterprises are mainly made of corundum-mullite ceramic rollers. The main defect is that the thermal expansion coefficient is high. In the area with higher temperature and the area with large temperature difference in the quenching zone, ceramic rollers are prone to bending deformation during use, which affects normal production. [0004] A...
