| Abstract: | In view of the current conditions in the Steel making Plant of Panzhihua Steel & Vanadium Co.,Ltd,it's affirmed that by improving the technologies of steel making it is possible to increase the endpoint carbon content of the steel to0.1 % ~0.2 % in refining the heavy rail steel in the converter.Results show that the endpoint phosphor and oxygen content in steel are rduced in great breadth and the quality fraction of the endpoint carbon can be raised to0.145 % and the quality fraction of the endpoint phospho... |
