武钢鄂州球团厂精矿干燥机自2005年12月投产后,陆续出现托轮轴断裂,托轮、滚圈、挡轮以及大齿圈等部件表面开裂问题,虽经多次修补,始终无法解决,严重影响了生产。通过对出现问题的各部件进行强度和负载计算,从设备结构、尺寸、材质和热处理等方面提出了相应的解决措施。按设计方案改造后,该设备已稳定运行3年多,完全满足了生产要求。
After the WISCO Ezhou pellet mill concentrate drier was put into operation in December 2005, the problems of cracking on the surfaces of the support shaft, the support roller, the rolling ring, the retaining wheel and the large gear ring appear one after another. Although it has been repaired many times, it can not be solved , Seriously affected the production. Through the calculation of the strength and load of the components that have problems, the corresponding solutions are put forward from the aspects of equipment structure, size, material and heat treatment. According to the design of the transformation, the device has been stable operation for more than 3 years, fully meet the production requirements.
