Abstract

The invention provides a control method for macular corrosion of a cold rolling pickling machine set. The control method comprises the following steps: first, determining possible reasons for formation of the macular corrosion, and then controlling the formation of the macular corrosion according to the possible reasons for the formation of the macular corrosion, wherein the possible reasons for the formation of the macular corrosion comprises the following seven types: the macular corrosion formed in a low-speed process of a process stage, the macular corrosion formed by over-high concentration of residual C1 on the surface of band steel, the macular corrosion formed by excessive temperature difference between a water temperature and an acid temperature in a bleaching stage, the macular corrosion formed by accidental shutdown or slow speed, the macular corrosion formed by low pressure of a squeezing roller and low temperature of a drying machine in the process stage, the macular corrosion formed by instability of voltage of an electrostatic oiler, and the macular corrosion formed by high humidity in a working field. By utilizing the control method for the macular corrosion of the cold rolling pickling machine set, the problems of great loss and the like caused by the defect of the macular corrosion of the band steel can be solved.

Description

technical field [0001] The invention relates to the technical field of cold-rolled pickling, and more specifically, to a method for controlling macular corrosion of a cold-rolled pickling unit. Background technique [0002] For pickling units producing finished products, macular corrosion defects have always been a defect that is difficult to control in major steel mills. The occurrence of this defect is affected by many factors in various links such as process, equipment, and management. Hiddenness, sometimes it takes several months to store the surface of the steel plate to appear, and the cause analysis is also difficult. A large number of macular rust defects make users unable to use it, resulting in product scrapping and economic losses. [0003] Therefore, in order to solve the above problems, the present invention provides a method for controlling macular corrosion of a cold-rolled pickling unit. Contents of the invention [0004] In view of the above problems, th...
