FIELD: metallurgical industry, namely production of springy steel strip and treatment of it. SUBSTANCE: strip blank is made by continuous casting process. Strip blank is heated up in inductor and its temperature is equalized. Then strip is subjected to combination rolling in planetary rolling stand and further in sizing rolls at controlling its temperature. Ready strip is heated up by induction or electric-contact process. Then strip loop is formed and strip is stopped behind loop. Strip is cut by measured length pieces and they are simultaneously perforated. Strip pieces are subjected to hot bending for making springy fasteners for rails and quenching them. EFFECT: possibility of making high-quality small-width strip of springy steel subjected to subsequent treatment for providing its predetermined stable physicomechanical properties in narrow range of characteristics. 7 cl, 1 dwg, 1 ex
