The data, such as the quantity of the slag involved in the mould as well as the mean residence time and so on, are measured within an organic glass model with the ratio of 1 : 0.

Research on the effects of Al-CaO based and Al-Ca based conditioning flux on the BOF tapping slag and the steel in the ladle was carried out in 180 tons ladles.

An Al-Ca-based conditioning flux was newly developed and the comparative experiments were carried out between the conventional Al-CaO-based and the Al-Cabased conditioning fluxes to control the tapping slag in ladle for the 180 t BOF at a certain steel plant.

Research on the effects of Al-CaO based and Al-Ca based conditioning flux on the BOF tapping slag and the steel in the ladle were carried out in Ansteel.

It is suggested that suitable ratio of reductants,fast reaction at early period of smelting process and addition of returning steel be applied for decreasing slag amount.

Through theoretical and experimental analysis on the effects of the initial sulfur content,desulphurizing refining slag,oxygen content and slag amount in the hot metal on the hot metal deep desulphurization a few main conditions required for hot metal deep desulphurization in the inducton furnace have been determined.
