Embodiment Construction

[0022] An on-site operation case of a production planning optimization method for reducing steel plate sampling loss in a manufacturing system is as follows:

[0023] Order 1: Standard GB / T 3274-2007, grade Q235B, thickness*width*length*blocks are 22*3000*9000*12, process delivery status AR;

[0024] Order 2: Standard GB / T 3274-2007, brand Q235B, thickness*width*length*blocks are 22*2800*9600*24, process delivery status AR;

[0025] Order 3: Standard GB / T 3274-2007, grade Q235B, thickness*width*length*blocks 22*2900*9800*6, process delivery status AR;

[0026] The performance test requirements of Q235B stipulated in the standard of the production plant are: tensile test, bending test, impact test, sampling according to batches, each batch shall not exceed 60 tons, and each batch shall consist of the same brand, the same heat, the same quality grade, Composed of steel plates in the same delivery state and thickness.

[0027] 1. Increase the virtual material number

Abstract

The invention discloses a production planning optimization method for reducing steel plate sampling loss in a manufacturing system, which belongs to the fields of manufacturing and information technology. This method is to solve the problem of reducing the loss of batch sampling of steel plates. In this method, after the material design is completed in the manufacturing system, a virtual material number is added to each planned material in each process, and the relationship between each virtual material number is established; then, the slab virtual material number is grouped according to relevant production information, Specify sampling slabs and spare sampling slabs for each sampling batch according to user rules, generate sampling codes and corresponding inspection items for sampling slabs and spare sampling slabs, and match sampling codes for all slabs in this batch; If there is a problem with the sample slab, use the virtual material number of the spare sampling slab to correspond to the virtual material number of the rolled large slab to issue a sampling plan, and inherit the sampling code and corresponding inspection of the previous slab according to the large slab. Compared with the method of increasing the sampling size in the traditional method, the method reduces the sampling loss and improves the finished product rate.

Description

technical field [0001] The invention belongs to the fields of manufacturing and information technology, and in particular relates to a production plan optimization method for reducing steel plate sampling loss in a manufacturing system. Background technique [0002] When the steel plate is delivered, it is generally required to submit a test report on mechanical properties and process properties. The manufacturer ensures that the performance test meets the order requirements by controlling the chemical composition of the billet, heating system, and rolling process, and obtains the test results through sampling, processing, and testing. [0003] For the sampling size of the steel plate, the common practice in material design is: increase the sampling size on each large plate rolled from the billet, so as to ensure that there will be no short-length phenomenon during real-time batch sampling on site, but the disadvantage is that the size Batch sampling of steel plates for deli...
