| Abstract: | Abstract: The technologies of the slag door carbon-oxy gen lance, the burner for both of oil-oxygen intensifying melting and post com bustion of CO and the EBT oxygen lance adopted in Laiwu Special Steel, improve the oxygen-using level of the EAF, reduce electric consumption about 130 kW ?h/t, shorten the tap to tap time by 20 min and cut down the melting costs by 40 yuan/t. These technologies are useful for revamping 30 ~ 60 ton EAF. |
