Abstract:In this paper, the failure mode and cause of heating in the baking furnace of enameller are studied and analyzed. The results show that the main reasons that affect the heating failure of the oven are the damage and abnormal assembly of the heating pipe,the particle impurities such as metal compounds on the catalyst surface, and the unreasonable setting of the rotation speed of the exhaust fan. The reasonable and practical technical measures for the heating pipe, the catalyst and the exhaust fan are put forward to help reduce the heating failure of the oven and improve the heating effect.
