Cold Roll Mill For 20mm ~ 220mm Precision Carbon Alloy Stainless Steel Pipes And Tubes
I. Production characteristics of cold rolling mill
1. During the cold rolling process, the billet is subjected to three-dimensional compressive stress, the structure and grains are fine, and the mechanical and physical properties are good.
2. The ability to correct the original wall thickness is large, the geometric dimensions are accurate, and the surface finish is high.
3. The deformation of the pass is large, the pipe wall pressure is 75% ~ 85%, and the diameter reduction is 65%.
4. Greatly reduce intermediate processes, such as heat treatment, pickling, heading, straightening, and sawing, shorten the process flow, reduce the loss of metal materials, and increase the yield.
II. Cold rolling process and advantages of finished products
Raw material: Hot rolled hollow tube after pickling and phosphating.
Finished products: High precision steel pipes.
Advantages of finished products by cold rolling: Cold-rolled steel tube has high dimensional precision, low surface roughness value, good performance, wide production size range, thin wall thickness, and has been widely used in all walks of life.
