Description

Technical Field

[0001] The utility model relates to the technical field of hot rolling mills, in particular to a smoke exhaust purification device for a hot rolling mill. Background Art

[0002] Hot rolling is relative to cold rolling. Cold rolling is rolling performed below the crystallization temperature, while hot rolling is rolling performed above the crystallization temperature. Simply put, a steel billet is heated and then rolled several times, then trimmed and corrected into a steel plate. This is called hot rolling, which can significantly reduce energy consumption and costs. 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 performance of metals and alloys, that is, the coarse grains in the cast state are broken, cracks are significantly healed, casting defects are reduced or eliminated, the cast structure is transformed into a deformed structure, and the processing performance of the alloy is improved. The hot rolling mill will produce smoke when working, and the existing purification methods all use filters for direct purification. Due to the high temperature of the smoke, the filter is easily damaged, which reduces the service life of the filter and increases the purification cost of the enterprise. For this reason, we propose a hot rolling mill smoke purification device. Utility Model Content
