Pickling mill unit inlet steel coil pretreatment integrated system and pretreatment method

Abstract

The invention discloses an acid rolling unit inlet steel coil pretreatment integrated system and a pretreatment method and relates to the technical field of acid rolling units. The problems that most of the previous preparation work of an existing pickling rolling unit needs manual operation, only a single problem can be solved, and time and labor are consumed are solved. The integrated system is characterized in that a strap detaching unit recognizes the strap head of a strap and detach the strap, and after bundle detaching is completed, a detaching completion signal is sent to a steel coil state information detection unit; the steel coil state information detection unit obtains the state information of the current steel coil; the state information of the current steel coil is sent to the end surface defect detection unit; the end face defect detection unit performs steel coil end face quality defect detection and thickness measurement according to the state information of the current steel coil, and sends the detection information to the code spraying recognition unit; the sprayed code recognition unit confirms the state of the defective steel coil and determines the picture where the sprayed code is located, the text of the sprayed code picture is detected and recognized, and the recognized information is compared with the ID read by the upper computer. The method is applied to metallurgy.
