保定模具加工厂

路沿石钢模具热处理工艺包括基体强韧化和表面强化处理,基体强韧化在于提高基体的强度和韧性,减少断裂和变形,故它的常规热处理必须严格按工艺进行。表面强化的主要目的是提高模具表面的耐磨性、耐蚀性和润滑性能。表面强化处理方法很多,主要有渗碳、渗氮、渗硫、渗硼、氮碳共渗、渗金属等。路沿石钢模具采用不同的表面强化处理工艺,可使路沿石钢模具使用寿命提高几倍甚至于几十倍,近几年又出现了一些新的表面强化工艺。

The heat treatment process of the road steel stony die includes matrix strengthening and toughening and surface strengthening. The strengthening and toughening of the matrix is to improve the strength and toughness of the matrix, reduce the fracture and deformation, so its conventional heat treatment must be strictly carried out according to the technology. The main purpose of surface hardening is to improve the wear resistance, corrosion resistance and lubricity of the surface of the die. There are many methods of surface strengthening, including carburizing, nitriding, sulphur infiltration, boronizing, nitrocarburizing, metal infiltration and so on. The application of different surface strengthening processes on the road steel stair mould can raise the service life of the stone along the steel bar several times, and even dozens of times. In recent years, some new surface strengthening technologies have appeared.
