In recent years, individuation of blade steel material is a great progress in manufacturing industry. Some enterprises design steel composition by themselves according to the product characteristics, and sign the supply and demand agreement with the steel plant. Among them, CR8 series is the most competitive and has produced great social and economic benefits. It is a new blade material worthy of attention and promotion. Here introduce two methods in Carbide Circular Slitter Round Blade production process.
Computer technology applicated in heat treatment is progress of computer technology and demand of industrial development's product. To some extent, temperature determines everything. Phase transformation is caused by temperature change, and deformation is caused by temperature. Konetool has successfully and stably applied computer temperature control technology in mechanical blade heat treatment. And it has made great stride forward to intelligent heat treatment.
After normal quenching of high-speed steels , 25%-35% retained austenite(rR) . If rR is not stable, it would turn into martensite. During martensitic transformation, when stress is lower than yield strength, plastic deformation will occur. This phenomenon is named martensitic transformation plasticity.
For many years,heat correction of quenched parts is believed can achieve remarkable results. Although it contains factor will cause thermoplasticity and contribution of good rR plasticity, most important one is phase transformation superplasticity's effect. Superplasticity effect of phase transformation occurs inwhole process of R → M phase transition, but this effect is transient. When phase transformation is most intense, superplasticity effect of phase transformation is the most significant, so frequency curve of plastic variable should demonstrate peak value.
Metal heat treatment is one of important processes in mechanical manufacturing. Compared with other processing technologies, heat treatment generally does not change shape and chemical composition of whole workpiece, but endows or improves performance of workpiece by changing internal microstructure or chemical composition of workpiece surface. Its characteristic is to improve the internal quality of workpiece, which is generally not visible to naked eye.
