Recently, for the first time in Changlai project, a new wear-resistant coating material has been used to replace the original welding wear-resistant strip as the wear-resistant coating at some guide chutes and feed inlets, which has significantly improved the production efficiency of sand and gravel aggregates.
It is reported that the wear-resistant coating is a composite material with hard spherical ceramic particles and quartz as the aggregate, which is mainly used to repair large area wear of equipment under fine particle impact conditions or to make pre-protective coatings. Therefore, the coating is suitable for the guide chute and the inner wall of the feed inlet of the irregular and arc-shaped sandstone aggregate with the particle size of less than 20 millimeters. The new wear-resistant coating used this time has obvious advantages in reducing environmental pollution and saving resource costs compared with the previous welding anti-wear treatment of wear-resistant welding rods. Because its main materials are small particles of ceramics and quartz, it has the advantages of strong adhesion, good quick-drying, safety, environmental protection and degradability, and the man-hour cost is significantly reduced compared with the wear-resistant welding reinforcement of the inner wall.
This measure solves the problem that it is inconvenient to add lining plates to the inner walls of irregular and arc-shaped guide grooves and feed inlets for anti-wear protection, and also greatly reduces the labor cost and production cost. Taking the inner wall of the feed inlet of the rod mill as an example, it takes two days to weld a 1 cm wear-resistant protective layer on the inner wall of the feed inlet of the rod mill, and after using the new material, it can be reduced to half an hour to complete the treatment of a 2 cm wear-resistant coating protective layer, which reduces the repair time, improves the service life of the inner wall protective layer, and has the characteristics of green environmental protection, degradability and low pollution. The construction concept of "civilized production". In the process of construction and operation
, Changlai Project has been adhering to the concept of "innovation, coordination, green, open and sharing", bearing in mind that "green water and green hills are Jinshan and Yinshan", protecting the environment while protecting production and green while protecting output. In the future, Changlai Project will continue to take "green environmental protection" as the premise of development. On the premise of long-term development, we should root in the green concept and take a good road of green development.
