Embodiment

[0076] EXAMPLES: A user ordering the standard Q / HG 032-2018, a license number HC250IF, a specifications 1.2 * 1163mm.

[0077] The first step is based on the user's demand information as the delivery standard for chemical composition, mechanical performance and other indicators use the enterprise standard Q / HG 032-2018, thickness tolerance adopts standard PT.a GB / T 709-2019 general precision, width tolerance adopts standard PW.A GB / T 709-2019 Normal Accuracy, according to customer requirements, the micro-negative tolerance is taken.

[0078] The second step is converted to the production process information according to the delivery standard. The performance requirements in delivery standards are 250-360MPa, tensile strength ≥440MPa, etc., Q / HG 032-2018 standard ingredients require C ≤ 0.008%, Si ≤ 0.8%, Mn ≤ 1.2%, etc., to meet user performance requirements The ingredients were tamperized to control C ≤ 0.004%, the Si content was 0.4-0.5%, the Mn content was 0.6-0.8%.

Abstract

The invention relates to a steel strip product whole-process quality control and automatic grade judgment method, and belongs to the technical field of cold-rolled automobile sheet production methods. According to the technical scheme, production and manufacturing standards are converted according to the requirements of users, all process parameters can be selected and can be located at different positions of the head, the middle and the tail, a judgment rule allowing the disqualification ratio can be set, and automatic blocking and degradation are carried out in a grade and score double-evaluation mode. The full-process quality control and automatic grade judgment system has the beneficial effects that the special requirements of customers are met, the enthusiasm of employees can be stimulated according to score value quantification, the labor force of manual judgment is liberated, and finally, the product quality control and the economic benefits of enterprises are effectively improved.

Description

Technical field [0001] The present invention relates to a method of multi-process quality control and automatic quotation of steel belt products, belonging to the technical field of production methods of cold rolling pulley. Background technique [0002] The automotive industry is a pillar industry that affects national economic development, technological advancements and social modernization. The development of automotive industries and steel materials are inseparable, and the automotive manufacturing industry is the largest user of thin steel plates. Nowadays, now, the competition in the automotive board market has become more and more strict, and the customer is more strict, the surface is high quality, the delivery is stable, and the user's use of stability is more dazzling. The traditional artificial judgment quality is largely reduced. Order delivery rate and unnecessary product quality control waste. [0003] China Patent Application No. 201210084480.5, a method of automat...
