The purpose of work: to describe the theoretical basics of controlling the nitride and nitride-sulphidic phases for perfecting the technological melting processes of low-alloyed steels. The variants of complex modifying the low-alloyed steels are developed. The dependences between physical and mechanical properties and developed variants of modipying are receivel. The optimum variant of modifying (titanium in complex with nitrogen and SiCa) is depined. The influence of non-metal inclusions and structure of forming the physical and mechanical properties of steels is estimated. The ratio between contents of nitrogen, sulphur, nitride-, and sulpurforming elements has been received.The regions of using the work results are metallurgical and machinery industry.
