Silicon carbide roller for transmission of roller kiln and preparation method and application of silicon carbide roller
The invention relates to a silicon carbide roller rod for roller kiln transmission and a preparation method and application thereof. The mass fraction of silicon carbide in the silicon carbide roller rod for roller kiln transmission is larger than 85%, the density is larger than or equal to 3.02 kg/m < 3 >, the porosity is smaller than 0.1%, and the bending strength at the temperature of 1200 DEG C ranges from 330 MPa to 360 MPa. And the straightness of the steel plate reaches 0.01%-0.8%. The preparation method of the silicon carbide roller comprises the following steps: burdening, mixing, vacuum forming, drying, shaping, reactive sintering, sand blasting, testing, packaging and the like. Through reasonable doping and matching of old materials and raw materials and strict control of the mixing process, the obtained silicon carbide roller rod is used as a transmission device of a lithium battery positive and negative electrode material sintering roller kiln, and is good in performance, long in service life and suitable for popularization and application.
本发明涉及一种辊道窑传动用碳化硅辊棒及其制备方法与应用，其中辊道窑传动用碳化硅辊棒中碳化硅的质量分数大于85％，密度≥3.02kg/m3，气孔率＜0.1％，1200℃的弯曲强度为330MPa～360MPa。且其直线度达0.1‰～0.8‰。该碳化硅辊棒的制备方法包括：配料、混料、真空成型、烘干、整形、反应烧结、喷砂、测试和包装等步骤。本发明通过旧料与原料的合理掺杂配比，严格控制混料过程，得到的碳化硅辊棒用作锂电池正负极材料烧结辊道窑炉的传动装置，性能良好，使用寿命长，适合推广应用。
