FIELD: rolled stock production, namely hot rolling of merchant rod of carbon steel used for drawing rope wire.
SUBSTANCE: method comprises steps of heating blank till austenization temperature, multiply reducing it in vertical and horizontal grooved rolls at normalized temperature of rolling process termination; cooling blank with water. Rolling process is realized at total elongation degree no less than 300 at elongation value for one pass in range 1.15 - 1.47. Temperature of rolling process termination is sustained in range 970 -1050°C. Article is cooled with water till temperature 730 - 790°C.
EFFECT: desired degree of working microstructure of carbon steel, elimination of flaw formation in strip.
