FIELD: metallurgical industry; may be used in industrial methods of ladle refining of liquid steel. SUBSTANCE: ladle lined with refractory material has bottom plate and two hollows filled with metal and slag, respectively. Two hollows form suspended bottom made of refractory sectors. Sectors with their one end are secured to refractory brickwork of ladle bottom plate, and sections with their other end rest on side walls. Sectors for interbottom shaped hollows are filled with refinery slag. Suspended bottom has central hole and side holes arranged round central one. Suspended bottom has also holes located by radii of joint of all sections. Means for ladle rotation is made in the form of turnable with drive of reversing rotation. EFFECT: higher degree of metal refining from nonmetallic inclusions, and reduced heat losses. 3 dwg
