A research purpose is exposures of conformities to the law of reactions between a cut-in in liquid steel oxygen, aluminium, calcium and sulphur, correlation of their concentrations in the conditions of equilibrium and in the process of co-operation in a сталерозливочном scoop with the purpose of improvement of quality of сталей, which are smelted on the industrial enterprises of Ukraine. Research methods thermodynamics analysis of equilibrium between deoxidants and oxygen; clarification of constants of equilibrium of different reactions; determination of sulfide and нитридной capacities tangent will make steel; електрохимический method of determination of activity of cut-in in steel oxygen. On the basis of the newest experimental information the new values of parameters of co-operation are expected 1 and 2 orders. It allows to make more exact calculations of reaction deoxidation. The improved diagram of solubility is created for the system of Fe-Ca-Al-O. On the basis of values of parameters, exposed to experimental research pilot-scale, factors, providing the decline of nonmetallicss in steel, are certain. Influence is set grey on the amount of calcium or magnesium, necessary for the delete of nonmetallicss. Necessary quantitative correlation of Ca/Aloks is set for the receipt of the remaining least of nonmetallicss. Calculations are conducted and maximal maintenance of magnesium is certain in composition of weighing material of powder-like wire, which provides interfusion of metal, the same as a calcium. On the basis of calculations of sulfide and nitride capacities on composition of steel the values of activity of components of products of раскисления are expected. It allows to find the values of concentration of modifiers, providing more complete delete of nonmetallicss. STALEMATE of "Azovstal'", STALEMATE of "MK the name of Il'icha" (Mariupol) is offered mode of treatment a silicocalcium in a scoop which will provide stable remaining maintenance of calcium in steel, and will allow to improve macro and microstructure of сontsnuons purveyances, to decrease on 0,5-1,0 mark degree of contamination became nonmetallicss. Plasticity must grow due to it, cold resistans and isotropi of mechanical properties of thick sheet rental. Use area - iron and steel industry.
