轮带是回转窑中承受并传递筒体重量的主要零件,处在较高温度下连续作业,表面点蚀和磨损比较利害,维修和更换都必须停机,影响生产。因此,不仅要求轮带有足够的强度,而且还要有较高的硬度和接触疲劳强度。轮带铸造质量的优劣将直接影响到整套设备的工作和寿命。由于轮带的结构不一,特别 Belt is the kiln in the bear and pass the weight of the main parts of the cylinder, at a continuous operation at higher temperatures, surface pitting and wear more interest, maintenance and replacement must be shut down, affecting production. Therefore, it is not only required that the belt have sufficient strength, but also high hardness and contact fatigue strength. The pros and cons of tire casting quality will directly affect the whole set of equipment work and life. Due to the different structure of the wheel, especially
