As long as the metal products in the hardware industry need to go through a series of processing procedures before they can be extended to other industries for use and operation. The processed metal material will be of higher quality than the original metal material. Its properties, characteristics and related physical properties will be continuously transformed and upgraded with the processing steps. Asp60 high speed steel is a frequently seen steel product, and the hot rolling stage is an essential processing step. So what changes can hot rolling technology bring to this kind of steel?
Hot rolling is relative to cold rolling. Cold rolling is rolling below the recrystallization temperature, and hot rolling is rolling above the recrystallization temperature. In short, a billet is heated and rolled several times, then trimmed and corrected into a steel plate. This is called hot rolling. It can significantly reduce energy consumption and cost. During hot rolling, the metal has high plasticity and low deformation resistance, which greatly reduces the energy consumption of metal deformation. Hot rolling can improve the processing properties of metals and alloys, that is, the coarse grains in the casting state are broken, the cracks heal significantly, the casting defects are reduced or eliminated, the as cast structure is transformed into deformation structure, and the processing properties of alloys are improved.
What are the effects of hot rolling on sp60 high speed steel? Low energy consumption, good plastic processing, low deformation resistance, no obvious work hardening, easy rolling, reducing the energy consumption required for metal deformation. Hot rolling usually adopts large ingot and large reduction rolling, with fast production rhythm and large output, which creates conditions for large-scale production. The as cast structure is transformed into processing structure by hot rolling, and the plasticity of the material is greatly improved by the transformation of structure. The characteristics of rolling mode determine the anisotropy of sheet properties after rolling. First, there are obvious performance differences in longitudinal, transverse and high directions of materials. Second, there are deformation texture and recrystallization texture, and there are obvious directionality in punching properties.
