Description
Technical Field
The invention relates to the technical field of coil production and processing control, in particular to an automatic sorting control system, automatic sorting equipment and a control method for a defective plate.
Background
The steel coil is rolled by a single steel billet, and in the surface treatment processes of rolling, subsequent galvanization and the like, fine defect points are easily left on one or more points of the strip steel due to the defects of rolling or certain equipment; the defect meter can automatically check and record in the production process of the raw material roll. And the subsequent steel coil is used as a raw material to be wound on a machine for uncoiling, flattening and slitting, and the steel coil is required to have certain thickness and minimum coil diameter (if the thickness can not be less than 3 tons) when being wound by the uncoiler, otherwise the winding can not be finished.
Aiming at the fine defects generated in the production process of the steel coil, if the end part of the steel coil is cut off, the steel coil can be delivered, but if the defects are at the length position of 2 tons of the strip steel, if the defects at the position are cut off, the cut-off 2 tons of coil materials can not be used and must be discarded; if a roll has multiple defect sites, it may even result in the rejection of the entire 20 ton roll.
Generally, in order to prevent the steel coil raw material from rusting in the transportation process, the steel coil raw material is coated with oil, and because the defects are very fine, partial defects after the oil coating are covered by an oil film, and the steel coil raw material cannot be sorted and identified through a surface inspection instrument in the subsequent production process. And a set of meter inspection instrument has over 200 ten thousand investment, too high cost and poor effect. At present, each production plant basically relies on manual visual inspection to carry out separation above equipment, the observation area is large, the quality problem caused by the fact that defects are easy to leak and mixed into finished products due to visual fatigue, separation experience and other factors is easily caused by manual separation, and personnel need to pay high attention in the separation operation process, so that the labor intensity is high.
Based on the above situation, if the raw material manufacturer records the defect position during production, and transmits the coil stock and the defect position information to the subsequent manufacturer, the subsequent manufacturer can accurately position the defect position point of the defect plate and sort the defect position point by using the position information input system in the uncoiling production process, thereby improving the sorting efficiency, reducing the rejection rate and reducing the labor consumption.
