Board quality detection real-time calculation system and method

Abstract

The invention discloses a board quality detection real-time calculation system and method, which belong to the field of hot-rolling quality detection of high-end boards in iron and steel industry, and are particularly used for performing real-time calculation on technological parameter indexes of a quality detection process of the high-end boards. The invention aims to reduce the missing detection rate and increase the product qualification rate. The system comprises a rolling mill data acquisition device, a process database, a business database and an index real-time processing module. The rolling mill data acquisition device stores collected data in the process database; the process database is connected with the index real-time processing module; the business database performs data exchange with the index real-time processing module; the business database stores calculation rule standards and calculation result information; and the index real-time processing module gives out a final detection result. The indexes are calculated in time; the quality detection is comprehensively covered; and standardization rules are adopted.

Description

technical field [0001] The invention belongs to the field of hot-rolled quality detection of high-end plates in the iron and steel industry, and in particular aims at the real-time calculation of process technical parameter indexes for the quality detection of high-end plates. Background technique [0002] The quality inspection of high-end steel plates has gradually shifted from focusing on results to focusing on process. The quality inspection of products in the process of processing will involve the calculation of indicators of various process parameters, such as: average temperature of finishing rolling, pass rate of thickness, and wedge hit rate. Such process data can generally be drawn as a curve according to the different positions or times of the steel coil. The index results calculated by the curve will determine the subsequent process route and product flow direction of the product, and ultimately affect product quality and enterprise cost. [0003] At this stage,...

Such process data can generally be drawn as a curve according to different positions or times of steel coils. The index results calculated by the curve will determine the subsequent process route and product flow direction of the product, and ultimately affect product quality and enterprise cost.

[0003] At this stage, the calculation of such indicators is generally carried out by means of random inspection or returning to inspection after quality objections occur, resulting in missed inspection of product process quality; the calculation of indicators is carried out in tools such as EXCEL after manual copying of data, resulting in lagging indicators, poor stability, Poor accuracy, which in turn leads to false detection of product quality
