Application and manufacturing process of bimetallic wear-resistant pipes
1、 The bimetallic wear-resistant pipeline is manufactured with an outer steel body according to the planning requirements. The inner wall and outer arc of the steel body require a wear-resistant layer with some welding hanging points, so that the wear-resistant layer can firmly adhere to the inner wall of the pipeline.
2、 Manufacturing of lost foam grinding tools, the thickness of the outer arc wear-resistant layer is 40mm, gradually thinning towards both ends, with a thickness of 20mm. Taking the outer arc of the pipeline as the center point, extend 105 ° -100 ° towards both sides of the pipeline inner wall, and apply the lost foam to the outer arc of the pipeline inner wall. Brush the slurry and dry it.
3、 Bury the thoroughly dried office products into the casting sand, cast KMTBCR28, and naturally cool them after casting. Repair the unevenness and burrs of the mold, apply paint, and mark them.
4、 Advantages of bimetallic wear-resistant pipes: For different degrees of wear in various parts of the pipeline, using a common plan extends the service life of the bimetallic wear-resistant pipes, making the service life of the bimetallic wear-resistant pipes adjustable within 6 years, reducing the inherent weight of the bimetallic wear-resistant pipes, and greatly reducing the investment cost. The excellent wear resistance guaranteed by KMTBCr28 raw material has been jointly planned to address the issue of falling of pipeline wear resistance layer.
The bimetallic wear-resistant pipeline is usually used at the inlet of the coal mill in power plants, because the working medium (coal block) is relatively large and has strong impact force. During the coal falling process, the outer arc of the bimetallic wear-resistant pipeline is severely worn, while the inner arc is not worn. Based on this application environment, our company has developed bimetallic wear-resistant pipes.
