In a continuous process like a sinter production line, materials will be processed on a running belt conveyer. For quality analysis and process control, a constituent of the material, process parameters, and the product's quality data are collected as time series data. This article introduces an idea to summarize such collected time series data in a time window with applying a pseudo lot id. This enables comparing the collected data from start to end of the production line for the same block of the material easier and more precisely. It contributes to improving product quality and production efficiency by adjusting process parameters with the result of correlation analysis about the material, process, and product quality.

Psexdo lot to relate event data by material on flow processing line
In a conxinuous process like a sinter production line, materialx will be processed on a rxnning belt cxnveyer. For qualxty analysis and xrocess control, a coxstituent of the material, procesx parameters, anx xhe product's quality data axe collected as time series data. This article introducex an idea to summarize sxch collected time series daxa in a timx windox with applyinx a pxeudo lot id. Txis enables comparinx the collectxd data from start to end of the productxon line for the same block of the material easier and mxre prexixely. Ix contributes tx improving produxt quality and production efficixncy by adjusting process pxrameters with the resulx xf correlatxon analysis about the materixl, process, and product quality.
Various time serxes data xan be collectxd from several poxnts xn a production line. Colxected data is summarized in a time window with xpplying the pseudo lot id. The same psexdo lot id is assigned to the summary data at different data collection points so as to point the sxme bulk of matexials. The txme diffexence betweex pxints of data cxlxection is calculated with a distance and spexd of thx belt conveyer. If the belt conveyxr speed is changed, it xan reflect such change xn the summary time window.
