Abstract

The invention discloses a low-cost anti-bending ceramic roller, which includes aggregate, matrix material and resin, wherein the main raw material formula of the aggregate in parts by weight is: 30-60 parts of ceramic roller waste; The main raw material formula of the base material in parts by weight is: 15-40 parts of cordierite, 2-15 parts of alumina, 0.1-8 parts of yttrium oxide, and 15-35 parts of clay; the resin is selected from water-soluble resin, and the parts by weight 0.1~2 parts. Correspondingly, the invention also discloses a preparation method of the low-cost anti-bending ceramic roller. With the present invention, the waste ceramic rollers are reused, and the problem that the corundum-mullite ceramic rollers are prone to bending and deformation in the quenching zone or the area with a large temperature difference is solved, and the brick running of ceramic tiles in the roller kiln is improved. Condition.

Description

technical field [0001] The invention relates to the technical field of processing and manufacturing ceramic rollers, in particular to a low-cost anti-bending ceramic roller and a preparation method thereof. Background technique [0002] Roller kilns are widely used in the production of construction, daily-use and sanitary ceramic products. As the key components of roller kiln and rolling kiln bed, ceramic rollers play the role of firing and conveying ceramic products and completing the sintering process, which directly affects development of the ceramic industry. [0003] At present, corundum-mullite ceramic rollers are the most widely used, but in the actual production process, a large amount of corundum-mullite roller waste is often produced, and the secondary utilization rate of waste in China is very low, so the roller waste is generally It is regarded as a non-degradable industrial solid waste pollutant, and it is also a waste of mineral resources. The widely used cor...
