Elements of Quality Analysis in Metallic Materials Production
The paper presents the main methods of technical-economical analysis of the quality of the metallic material production. The technical - economical analysis of the electric steels quality can be processed both for the product (electric steel) and for the company (electric steelworks). Both the analysis methods for products (A) and the ones for companies (B) are presented in comparison. There are mainly presented and analyzed a specific analysis models for steels elaboration in Electric Arc Furnace (EAF). The main elements specific to the two categories of analysis methods, including mathematical models. The quality of the steels elaborated in the EAF is a very important parameter. From this point of view, there is the need of analyzing the electric steels quality in various methods, including by technical-economical ones. The technical - economical analysis of the electric steels quality can be processed both for the product (electric steel) and for the company (electric steelworks). For the technical - economical analysis for the electric steels quality, we can use two methods: methods of the analysis for the products quality (MAPQ); methods of the analysis for the companys (MACQ).
