METHOD FOR MAKING WIRE, RODS AND SEAMLESS TUBES AND ROLLING PLANT FOR PERFORMING THE SAME Russian patent published in 2006 - IPC B21B1/18 B21B23/00 

FIELD: rolled stock production.

SUBSTANCE: method is realized due to selecting, if necessary piercing, rolling, drawing stages or additional operations. According to invention in main elongating section rolling is realized in three-roll continuous rolling mill used for piercing and rolling at making tubes and also for rolling solid products such as rods wire and similar articles. At rolling solid products mandrel stem used for piercing and rolling tubes is withdrawn to idle position and rolls calibrated for rolling tubes are changed by rolls prepared for rolling bars and calibrated to diameter usually exceeding that for rolling tubes. Rolling plant includes arranged in rolling direction and selected if necessary: piercing rolling mill; multi-stand elongating mill as main section; drawing mill; finish rolling mill; wire rolling mill; heating furnace; preheating furnace; roller tables and cooler. Main elongation section includes three-roll continuous rolling mill and apparatus for shifting mandrel stem.

EFFECT: possibility for realizing combined manufacturing processes for rolling different articles without increasing production surface areas.
