本文是在充分地研究钢管冷轧辊的技术条件和市售的等离子堆焊粉末的性质的基础上,更换了目前冷轧辊的基体材料,研制了适合于堆焊钢管冷轧辊曲面形的工作面的小型等离子粉末堆焊枪,选出了合适的合金粉末,确定了最佳工艺规范,并找出了防止堆焊层裂纹的工艺措施,为钢管冷轧辊延长使用寿命,降低成本,修复旧轧辊开辟了一个新的途径。
This article is based on the full research of the technical conditions of cold-rolled steel tube and the properties of commercially available plasma surfacing powder, based on the replacement of the current base material of cold-rolled roll, developed suitable for surfacing the surface of cold-rolled surfacing steel tube Small plasma powder welding torch, selected the appropriate alloy powder, to determine the best technical specifications, and to find out the process to prevent the crack of the surfacing layer of steel pipe cold roll to extend the service life, reduce costs and repair the old roll opened up A new way.
