Quality Control and Improvement of Cutting Edge of Cold-rolled Enamelled Steel
Based on the cutting edge principle of cold-rolled continuous annealing disc,the causes of af-fecting the edge quality of cold-rolled enamelled steel were studied.Detecting the width of raw materials and defects,improving the quality of the blades,and adjusting the disc cutting edge process parameters,blade inclination angle and deburring roller combined with field working conditions.A series of measures to ensure that the quality of enamelled steel edge qualified,burr was controlled within 1%to 3%of the thickness,and the unqualified rate of cutting edge quality was controlled within 0.8%,which improved the first hit rate of product and product image.
