The invention discloses an emulsified liquid residue blowdown and conversion device of a reversing cold mill. An upper bearing roller emulsified spraying beam, an upper middle roller emulsified spraying beam, an upper working roller seam emulsified liquid spraying beam, an upper anti-winding guide plate inner plate face emulsified liquid spraying beam, a lower anti-winding guide plate inner plate face emulsified liquid spraying beam, a lower working roller seam emulsified liquid spraying beam and a lower middle roller emulsified liquid spraying beam are symmetrically arranged on the inlet side and the outlet side of a rolling mill; all the emulsified liquid spraying beams are communicated with an emulsified liquid pipeline. A second one-way valve is arranged in front of a pipeline nozzle of the upper anti-winding guide plate inner plate face emulsified liquid spraying beam; a first one-way valve is connected near the pipeline of the upper anti-winding guide plate inner plate face emulsified liquid spraying beam and is connected with an air blowing connector; or a shuttle valve is arranged in front of the pipeline nozzle of the upper anti-winding guide plate inner plate face emulsified liquid spraying beam, and the two inlet ends of the shuttle valve are communicated with the emulsified liquid pipeline and an air blowing system respectively. By means of the emulsified liquid residue blowdown and conversion device of the reversing cold mill, the problem of emulsified liquid residue of the emulsified liquid nozzle is thoroughly solved.
Description
technical field [0001] The invention belongs to the technical field of strip steel cold rolling equipment, and relates to a reversible cold rolling emulsion residue blowing conversion device. Background technique [0002] In the strip steel cold rolling production line, sufficient emulsion injection should be carried out at the entrance of the rolling mill to lubricate and cool the roll and the plate surface, and the exit of the rolling mill should be closed and air purged to ensure the cleanliness of the plate surface. Generally, rolling mills are equipped with splash guards and anti-winding guide plates. The outlet splash guards and anti-winding guide plates can effectively prevent the emulsion on the roll from splashing onto the plate surface and the residual emulsion from the roll emulsion nozzle from flowing onto the plate surface. The anti-tangle guide plate is also equipped with a plate surface emulsion injection and purge system. The plate surface emulsion injection ...
