The rotary kiln shell is rolled from steel plates such as boiler plates and Q235C plates, and requires highly on dimensional accuracy and geometric tolerances. Its processing quality directly affects the strength and tightness of the component.

 

According to the detailed requirements of the drawings, and adopting the local forming method, the specific manufacturing process and welding method of single-section kiln shell are formulated. After the kiln shell is assembled and welded, post-weld processing is required, including non-destructive testing, post-weld heat treatment, pressure-resistant experiments and other technological processes to ensure the high quality of kiln shell.
