Real-time sampling and judging method for steel manufacturing system

Abstract

The invention discloses a real-time sampling and judging method for a steel manufacturing system, and belongs to the technical field of manufacturing industry and information. The method mainly aims to solve the problems of real-time sampling and system judgment in the production process of steel products. The method comprises the following steps: performing rule definition on inspection items, material trees and sample codes in a manufacturing system; during the material output, enabling the manufacturing system to acquire inspection items and related test requirements according to order information corresponding to material codes which are produced by the sampling process according to a plan; acquiring the billet heat information according to the material trees, inquiring whether available sample numbers exist or not through conditions: if available sample numbers exist and the relevant constraint conditions are met, determining that the material is not sampled and available sample codes are matched, otherwise, generating new sample codes and parameters to be matched with the material, and transmitting a result to a manufacturing system after sample machining and testing are completed; and enabling the manufacturing system to perform system judgment according to the test result and the judgment standard of the order requirement. Compared with traditional manual sampling, themethod has the advantages that sampling times and test times are reduced, and the delivery time is prolonged.

Description

technical field [0001] The invention belongs to the fields of manufacturing and information technology, and in particular relates to a real-time sampling and judging method for a steel manufacturing system. Background technique [0002] Steel products are generally required to submit mechanical performance and process performance test reports when they are delivered. The methods and judgment standards of performance tests will be described in the order standards, including inspection items, sampling methods, sampling quantities, test methods, judgment standards, etc. . [0003] In the actual production process, the production plant will carry out the sampling operation at the designated position of the product in the designated process. When sampling, first take a large sample, and then send the large sample to the sample processing factory to process into multiple samples that can be tested on the testing machine , the manufacturing system then conducts system judgment bas...

Problems solved by technology

[0004] Since the sampling methods include heat sampling, piece sampling, batch sampling, etc., the sampling by batch also stipulates the weight of each batch (different grades may be different), product thickness (generally the same thickness, some can be thicker) Generation thin), heat code, delivery status and other requirements, it is difficult for on-site personnel to operate accurately when sampling
