Study on EAF Roof Brick vs Pick-up in Melting of 2Cr18Ni11Ti Steel

摘要: 分析了攀钢集团成都钢铁有限责任公司用返回吹氧法冶炼2Cr18Ni11Ti钢之初,出现因使用磷酸盐结合的不烧高铝砖炉盖引起冶炼过程中两炉钢液严重增磷的情况和采取的对策。研究和实践证明,采用返回吹氧法冶炼2Cr18Ni11Ti钢时不能用磷酸盐结合的不烧高铝砖做电弧炉的炉盖砖。

Abstract: The investigation is made into the case that during the early operation of melting the 2Cr18Ni11Ti 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 the 2Cr18Ni11Ti steel with the return oxygen blast process.
