Mastering Production of 550 mm Dia Concast Rounds of Pipe Steel Grades in CCM No. 2 in the EAF Mill "Zhelezny Ozon 32"
It is shown that during commissioning of CCM № 2 and mastering the production of continuously cast billets diam. 460 and 550 mm made of pipe steel grades at an electric steelmaking facility «Iron ozone 32» problems associated with the occurrence of breakthroughs in the first months after putting into operation continuous casting machine № 2 were completely solved, and the number of billets with external surface defects and stress cracks was reduced. Production of CCB diam. 460 550 mm of 20, 09G2S, D, 13ХФА, 20ФА, etc. steel grades has been mastered.
