| Abstract: | The investigation is made into the case that during the early operation of melting the2Cr18Ni11Ti steel with the return oxygen blast process by Pangang Group Chengdu I&S Co.,Ltd.,and severepick-up occurs with two heats due to the furnace roof refractory work built with non-sintered phosphate-combined high alumina bricks,based on which,specific countermoves have been taken.Relevant studies and operations have brought about the conclusion that no non-sintered phosphate-combined high alumina bricks can be used to build up the EAF roof in case of melting the2Cr18Ni11Ti steel with the return oxygen blast process. |
