A Novel Method of Recycling CO2 for Slag Splashing in Converter

Converter off-gas, an important energy resource for steel industries, is one of the weak points in the recovery and utilization of secondary energy resources. To improve the level of recycling converter off-gas in steel plants, a novel approach to the recycle of CO2 separated from converter off-gas or other off-gas for the green slag splashing technique was developed, and the CO2 equilibrium conversion ratio of the green CO2 slag splashing under different technological conditions was calculated by the program of enthalpy (H), entropy (S), and heat capacity (C), i.e. HSC software. Furthermore, the experiments of CO2 injected into molten converter slag were curried out, and the influencing factors of the green slag splashing technique using CO2 were analyzed. The experimental results showed that the carbon content for smooth slag splashing using CO2 was about 4. 0%.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000285805400003&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Metallurgy & Metallurgical EngineeringSCI(E)2ARTICLE1211-161
