摘要
The tension leveler is generally set after the billet guide and the secondary cooling device, continuous casting machine for continuously casting and straightening billet, another important function of the tension leveler is to transport the spindle. The opening degree of the upper and lower rolls can be conveniently adjusted by the tension leveler to meet the different sectional sizes of the casting blank. At the same time to be flexible speed regulation to adapt to the speed change. The rollers of the leveler require adequate hardness and wear resistance, generally through surfacing or spray welding treatment, in this paper, the crack occurred shortly after the roller assembly of the export American leveler was used, from heat treatment, forging material, surfacing layer hardness analysis, summarize the causes of cracks.
