OPTIMIZATION FOR PROCESS OF DESOXYDATING STEEL WITH APPLICATION
HARDWARILY-PROGRAMMATIC COMPLEX «MASTER»
Zaporozhe state engineering academy, Ukraine
Use of a hardwarily-programmatic complex «Master» in the open-hearth shop of ОАJ «Metallurgical combine «Zaporozhstal» allowed to get economy of costns due to op-timization of expense of ferroalloys and materials for desoxydating of unkilled and semi-killed steel, and also decline of flaw of rerolling-quality metal. Optimization of expense of ferro-alloys and materials is arrived at the use of algorithm of simolex-method for the linear programming in combination with the thermodynamics model of the system «metal-slag-gas». The decline of flaw of rerolling-quality metal is reched due to stabilizing of its oxy-dation level and more exact prognostication of chemical composition of ladleman sample.
