Cold shearing is a vital industrial processing method and corresponding mechanical equipment specially designed for cutting various metal materials at room temperature. This mature cutting technology mainly targets long and strip-shaped metal workpieces in industrial production, usually including common metal profiles such as section steel, solid bar, and steel bar, which are widely applied in construction, machinery manufacturing and metallurgical fields. Different from hot shearing technology that requires high-temperature heating treatment, cold shearing completes the whole cutting and sizing process under normal temperature conditions without additional thermal processing, which can effectively avoid metal deformation, surface oxidation and internal structural changes caused by high-temperature operation. It ensures the original mechanical properties and surface quality of metal materials to the greatest extent.
As one of the core and key processing equipment in the finishing operation area of long products in the modern metallurgical industry, cold shearing equipment undertakes the essential post-processing procedure of continuous rolling production lines. In the conventional metallurgical production process, metal workpieces produced by continuous rolling units are usually in ultra-long continuous states after cooling and shaping, and cannot be directly used for subsequent processing and market delivery. Therefore, cold shearing machines play an indispensable role in cutting the cooled continuous rolled pieces accurately and stably into standard fixed lengths that meet customer design requirements and industrial application standards. With the advantages of simple operation, high cutting precision and stable working performance, cold shearing has become a standard supporting process for long metal product finishing, greatly improving the dimensional uniformity and product qualification rate of finished metal materials.
