Chemical property checking correction method for quality certificate of metallurgy enterprise resource planning system

A chemical property checking correction method for a quality certificate of a metallurgy enterprise resource planning system is mainly applied to metallurgy enterprise production quality management and comprises the following operation steps of: establishing a standard library table of ex-factory chemical components of finished products needed for chemical property checking correction in the enterprise resource planning system; inquiring in the standard library table of ex-factory chemical components of finished products according to inlet parameters; determining whether a chemical component standard data record is found out or not; correcting an input chemical property checking data value according to the found chemical component standard data stored in a temporary table; determining whether chemical property checking data not satisfying the standard is exists or not; determining whether chemical properties in the input chemical property checking data are less than those required by the chemical component standard data or not; and outputting the corrected chemical property checking data and feedback information. The chemical property checking correction method solves the problem of wrong chemical components of products in the quality certificate.
