Wear-resistant ceramic roller and preparation method thereof
The invention relates to a wear-resistant ceramic roller . The wear-resistant ceramic roller comprises a ceramic roller body and a supporting body, and the supporting body comprises outer transverse reinforcing ribs, inner supporting rings and connecting columns; the ceramic roller body is prepared from the following wear-resistant ceramic mixed raw materials, and thepreparation method comprises the following steps: adding water into the wear-resistant ceramic mixture, stirring to obtain pug, and refining the pug through a direct push type pug refining machine to obtain pug strips; putting into a mold provided with an inner support body, performing extrusion forming, and performing drying treatment; then carrying out cold isostatic pressing process treatment; and transferring into a high-temperature nitrogen furnace, sintering under the protection of flowing nitrogen, and cooling after reaction to obtain the wear-resistant ceramic roller. The wear-resistant ceramic roller disclosed by the invention has good wear resistance and high strength, still keeps good stability and weather resistance when being used at different temperatures, and is long in service life. The preparation method is simple, high in controllability and high in production efficiency. According to the wear-resistant ceramic roller product, the fire-resistant temperature is 1800 DEG C or above, and the Mohs hardness can reach 8.
本发明涉及一种耐磨陶瓷辊，包括陶瓷辊本体和支撑体，所述支撑体包括外横向加强筋、内支撑环和连接柱；陶瓷辊本体是由以下耐磨陶瓷混合原料制备而成，制备方法为将耐磨陶瓷混合料中加入水搅拌成泥料，将泥料通过直推式炼泥机进行炼泥得到泥条；放入设有内支撑体的模具内通过挤压成型，进行干燥处理；再进行冷等静压工艺处理；再转移至高温氮气炉内于流动氮气保护下进行烧结，待反应冷却后即可得到耐磨陶瓷辊。本发明的耐磨陶瓷辊，具有良好的耐磨性能和高强度，在不同的温度下使用，仍然保持有良好的稳定性和耐候性，使用寿命长。制备方法简单，可控性强、生产效率高。本发明的耐磨陶瓷辊产品，耐火温度为1800℃以上，莫氏硬度能达到8。
