Rotary kiln is a commonly used raw material calcining equipment in the cement building materials industry. During long-term operation, it is necessary to regularly check the operation status of equipment components to ensure the safe and stable operation of the equipment. While improving the economic benefits of the enterprise, it can also effectively prolong the service life of the equipment.

The rotary kiln cylinder is the support and rotating part of the rotary kiln equipment. During the operation of the equipment, when the equipment is in a high temperature state for a long time, the kiln mouth section will deform. , Manufacturers of rotary kilns generally have corresponding parts casting bases, you can contact after-sales maintenance or manufacturers for replacement.

The processing technology of the rotary kiln shell affects the quality of the rotary kiln. Rotary kiln cylinder is rolled from boiler plate, Q235C plate and other material steel plates. The dimensional accuracy and shape and position tolerance are required to be high. The processing quality directly affects the strength and tightness of the components.

The rotary kiln shell adopts the method of partial forming. According to the detailed requirements of the drawings, the specific production process and welding method of a single-section shell body are formulated. Because the outer circle of the shell is not processed, the verticality of the end face to the center of rotation cannot be directly measured. In the process design, the verticality of the end face is converted into the parallelism and the coincidence of the axes of both ends according to the structural form of the cylinder.

After the cylinder body is assembled and welded, post-weld treatment is required, including non-destructive testing, post-weld heat treatment, and pressure resistance tests to ensure the production of high-quality cylinder castings.
