IMPROVING THE EFFICIENCY OF CEMENT FURNACE BANDAGES REPAIR TECHNOLOGY THROUGH THE USE OF A NEW PROCESSING MODULE DESIGN

During the operation of large-sized kilns of cement plants, due to the design features and operating conditions, there is constant wear of the rolling surfaces of its supports, consisting of support rollers and bandages. A decrease in the accuracy of the shape caused by the wear of these surfaces can lead to distortion of the shape of the entire unit and its failure. To eliminate wear and bring the shape of the supports to the standard values of geometric tolerances, there are various technological processes of mechanical processing. The most effective of them are non-dismountable mobile repair technologies. A distinctive feature of this type of technological processes is that the machining of the rolling surface of the supports is carried out directly during the technological rotation of the firing furnaces, without stopping them. Subject to the use of existing methods for measuring the shape of the rolling surface of the bandages, the possibility of increasing the efficiency of their machining due to the integrated use of a new design of the processing module and a software module for constructing a route and calculating technological cutting modes is shown. The paper considers the main stages and methods of performing a new technological process of mechanical surface treatment of rolling bands of firing furnaces.
