Abstract

The invention discloses a wear-resistant high-performance ceramic roller rod and a preparation method thereof. The invention uses fused mullite and fused alumina to replace ordinary mullite and alumina by adjusting the weight of raw materials, so that the final obtained The advanced ceramic roller has excellent wear resistance and high temperature resistance. Adjusting and controlling the addition of inorganic fillers not only improves the strength of the ceramic roller, but also further enhances the thermal spalling resistance of the ceramic roller. The invention also discloses a preparation method of a wear-resistant high-performance ceramic roller rod, which adopts a spiral extrusion molding process, continuous extrusion molding, high production efficiency, high compactness and high mechanical strength of the ceramic roller rod, and reduces the production cost of the ceramic roller rod. The deformation and cracking of the ceramic roller improves the performance of the ceramic roller.

Description

technical field [0001] The invention relates to the technical field of ceramic rollers, in particular to a wear-resistant and high-performance ceramic roller rod and a preparation method thereof. Background technique [0002] Due to the characteristics of small firing temperature difference, short firing cycle, high yield, low energy consumption and easy control, roller kiln has been widely used in the production of building sanitary ceramics, daily-use porcelain, special ceramics, and glass and metal annealing. Wide range of applications. In the roller kiln, the roller rod is the most critical refractory material. It is a refractory product made of clay and natural minerals through selection, crushing, mixing, molding, and calcination. It mainly plays the role of carrying and conveying in the kiln. The role of the product. At present, with the expansion of the application range of roller kilns and the production needs of large specifications and high output in the field o...
