New patch structure and manufacturing method for cement industry tube mill

摘要

The present invention relates to a manufacture method of a novel lining plate structure for use with a tube mill of cement industry. The manufacture method of the novel lining plate of present invention has following three technical solutions: 1) metal lining plate, 2) ceramic lining plate, and 3) combined lining plate; the manufacture method of combined lining plate includes: ling the concave-convex space, formed in the combination of metal lining plate and tube body, with corundum ceramic lining plate; then installing the new combined lining plate on the steel plate of the tube body through inlaying, sticking and local welding. This service life of the new combined lining plate can be further enhanced and extended, and this improvement cannot be achieved by any form of existing lining plates. Under the same reference conditions of the present invention, the weight of lining plate is reduced 50%, saving the steel material consumption for more than 50%; and the service life of the lining plate for use with the tube mill of cement industry is doubled, up to 15000-20000 hours.
