Coil data tracking method for continuous hot-rolled slitting machine

Abstract

The invention provides a coil data tracking method for a continuous hot-rolled slitting machine to solve the problems in the prior art that the material flow is not matched with the information flow, the labor intensity of operation personnel is large and the like, and the method can alleviate the labor intensity of the operation personnel and can improve the information accuracy. The method comprises the following steps that: a mother coil number of a current mother coil is read by an uncoiler from a previously stored plan table; a plurality of small coil numbers are generated according to the read mother coil number and the quantity of small coils to be divided by the current mother coil, and the generated small coil numbers are stored in a temporary table; when a small coil completion signal which is 1 is received by a coiler, the small coiler number of a current small coil is read by the coiler from the temporary table to be written into a label of the current small coil; an electronic scale weighs the current small coil, and the measured weight is written into the label of the current small coil; when a mother coil completion signal is not 1, data tracking is executed for a next small coil; and if the mother coil completion signal is 1, data tracking is executed for a next mother coil.

Description

technical field [0001] The invention relates to a steel coil data tracking method for a hot continuous rolling slitting unit. Background technique [0002] The steel coil produced by the main rolling line is about 20 tons. Generally speaking, users cannot open such a large steel coil without professional equipment. Under normal circumstances, the user divides the steel coil into 2 small coils, each of which is about 10 tons; sometimes according to the specific needs of the user, the steel coil is divided into more small coils, for example, 3 or 4, but no more than 5. [0003] During the production process of the hot continuous rolling slitting unit, there is no effective means to track the data of the steel coil information, resulting in a mismatch between the logistics and the information flow. When the label is printed on the steel coil, the data information of the label is inconsistent with the actual product , resulting in a large number of quality objections, the econ...

Problems solved by technology

[0006] In view of the mismatch of logistics and information flow in the existing technology, the inconsistency between the data information of the label and the actual information of the item, the labor intensity caused by the manual input of the finished product label by the operator, the low work efficiency, and the low accuracy of the data, etc. Problem, the present invention proposes a steel coil data tracking method for a hot continuous rolling slitting unit, which includes an uncoiler, a five-roll leveler, a coiler and an electronic scale. The steel coil data tracking method of the hot continuous rolling slitting unit may include the following steps: (a) the uncoiler reads the parent coil number of the current parent coil from a pre-stored schedule; The parent volume number and the number of small volumes to be divided into the current parent volume to generate multiple small volume numbers, and store the generated multiple small volume numbers in the temporary table; (c) when the coiler receives a 1 When the small roll completes the signal, the coiler reads the small roll number of the current small roll from the temporary table, and writes it into the label of the current small roll; (d) the electronic scale weighs the current small roll, and the calculated Write the weight into the label of the current small roll; (e) if the parent roll completion signal received by the coiler is not 1, then repeat the operations from step (c) to step (d) for the next small roll; (f) if If the parent roll completion signal received by the coiler is 1, the above steps (a) to (e) are executed for the next parent roll
