In the liquid steel refining process the basicity of top slag can be increased, the melting point of the slag decreased and the fluidity improved by adding certain amount of active lime.

Because of high [Al] content,refining molten steel was easy to generate Al2O3 inclusion in the production process,resulting in poor liquidity and casting difficulties.

The experiment had indicated that selected the 4Cr3Mo2NiVNbB refine steel and carried on strengthen treatment could fully display special die-casting technique merit, the service life enhanced 3~4 times than the original 3Cr2W8V electric furnace steel, achieved the overseas similar products advanced level.

Experimental Study on Hot Simulation for Steel Temperature Rise in IR-UT-16 Refining Ladle;

The technical measures for increasing the service life of refining ladle lining were presented, and the influence of service conditions on the life during the campaign were investigated.

The practice and effect about unshaped refractory used on the permanent layer of 100t refining ladle is introduced and a whole tamping process with automatic material flow without mold is given.

Physical model of 150t ladle refining process;

Research for Cold Roll Blank Forged by Ladle Refining Ingot;

In view of the role the ladle refining plays and its final goal the present paper describes the design of the alloy burdening model by means of the RBF network and verification of the model according to the data acquired from the practical refining operation and comparison with the results of the model prediction and shows the applicability of the RBF network in the model.
