Abstract
The causes for failure of the bands of rotary kilns in operation are analyzed. The existing methods of repair of the through-thickness cracks in the bands without their dismantling from the kiln body are considered. Comparative analysis of the effectiveness of repair operations with application of arc and electroslag welding is given.
Keywords: rotary kilns, bands, cracks, repair methods, mounting conditions, electric arc welding, automatic welding, electroslag welding, multilayer electroslag welding
