Problems solved by technology

At present, the materials of refractory bricks in tunnel kilns are mostly high alumina, corundum, corundum mullite, etc. High alumina materials have high high temperature strength, but poor thermal shock resistance, short service life and high cost; corundum mullite Materials and materials have good comprehensive performance, but the cost is relatively high
[0004] Among them, the L-shaped plate is a commonly used ceramic ball fired plate, which requires good ingredients and good molding effect to ensure that the performance of the corners meets the standard without cracking. There is no mature process for preparing L-shaped plates using waste materials in the prior art.

Abstract

The invention discloses a ceramic ball fired plate and a preparation method thereof. The ceramic ball fired plate comprises the following raw materials in percentage by mass: 30-55% of ceramic roller waste, 5-20% of zirconium-aluminum brick waste, 10-30% of waste aluminum powder, 10-30% of kaolin, 0.1-1% of a dispersing agent and 0.1-1% of a binder. The ceramic ball fired plate has good high-temperature strength, high-temperature creep resistance, thermal shock resistance and erosion resistance, is low in cost and long in service life, and facilitates firing of high-quality ceramic balls.

Description

technical field [0001] The invention relates to the field of kiln furniture, in particular to a ceramic ball firing board and a preparation method thereof. Background technique [0002] Ball milling process is an important basic component of modern industry. Grinding media balls are among the most consumed consumables. At present, alumina grinding ball is the most widely used ceramic grinding medium material, and it is widely used in architectural ceramics, daily ceramics, electronic ceramics, cement mines and other fields. [0003] At present, most of the alumina grinding balls used in the domestic market are single alumina ceramic balls, and the firing process of alumina ceramic balls mostly uses tunnel kilns, which are low in cost and high in efficiency, and can be operated continuously. This requires the kiln furniture in the tunnel kiln to have the characteristics of good thermal shock resistance, high temperature strength, stable structure, and little pollution to si...
