Bluing packaged with pickling process

Bluing pack of pickling process to share the following operation, can draw lessons from the operation. 1, remove surface oxidation stainless steel in addition to surface oxidation stainless steel with physical method and chemical method. For the processing of cold rolled billet, is commonly used to increase the surface properties of the chemical method, which adopts the pickling method. Acid with hydrochloric acid, sulfuric acid is used, most use hydrochloric acid production line. Processing time is short, its quality also good. Is given priority to with chemical method, physical method as the auxiliary pole, with the two methods. Volume 2, plate, large scale to the next working procedure, the improve the operation efficiency, improving yield, more efficient use of storage sites of the factory, the hot rolled plate volume 2 - Three methods of welded together to increase cold rolled plate, shows its effect on instances. Commonly used welding machine operation time is short, the welding part of 凼 flash butt welding machine. 3, lubricating oil is for the purpose of rust, prevent the bluing packaged with bruises and assist when rolling lubrication, after acid pickling of strip on the coating on a layer of oil. 4, disc type trimming machine according to the order be beg to shear the strip width. And in order to avoid rolling accident caused by the width of the hot rolled plate volume change and carries on the cutting edge. 5, management of hot-rolled coil characteristics to examine the traits of hot-rolled coil, in order to improve the quality of raw material is miao, thus improve the quality of the finished product. Pickling line between hot rolling process and cold rolling process, on the quality management of each other, can be a very important line. Small make up: G
