Description

Hot rolling device for machining

Technical Field

The utility model relates to the technical field of machining, especially, relate to a hot rolling device for machining.

Background

As is well known, hot rolling is a rolling performed at a recrystallization temperature or lower, as opposed to cold rolling, which is a rolling performed at a recrystallization temperature or higher. Briefly, a slab is heated, then rolled several times, trimmed, and straightened into a sheet, which is called hot rolling. Can obviously reduce energy consumption and cost. The metal plasticity is high during hot rolling, the deformation resistance is low, and the energy consumption of metal deformation is greatly reduced. Hot rolling can improve the processing property of metal and alloy, i.e. crushing the coarse grains in casting state, healing the cracks obviously, reducing or eliminating casting defects, converting the as-cast structure into a deformed structure and improving the processing property of the alloy. The hot rolling is characterized in that: the energy consumption is low, the plastic processing is good, the deformation resistance is low, the processing hardening is not obvious, the rolling is easy to be carried out, and the energy consumption required by metal deformation is reduced; the hot rolling usually adopts large ingot casting and large reduction rolling, the production rhythm is fast, the yield is large, thus creating conditions for large-scale production; the cast structure is converted into a processed structure by hot rolling, and the plasticity of the material is greatly improved by the conversion of the structure; the characteristics of the rolling mode determine that the performance of the rolled plate has anisotropy, namely, the longitudinal direction, the transverse direction and the height direction of the material have obvious performance difference, and the deformation texture and the recrystallization texture exist, so that the punching performance has obvious directionality.

The existing hot rolling device needs manual adjustment, hot rolling work is carried out once, and the quality of parts after processing sometimes cannot meet the requirement.
