摘要： A method of introducing and mixing a refining agent into molten metal in a ladle using a lance having a refractory body shaped to facilitate the positioning of the lance in the ladle is disclosed. Several tubular members are positioned within the lance and communicate with vertically spaced openings in a common plane in a lower side wall thereof communicating with the interior of the ladle and the molten metal therein. Some of the openings are plugged with porous material and others form passageways for the refining agent such as an alloy wire or powder. Gas, such as argon, is introduced through the tubular members having porous plugs and delivered through the porous plugs so as to bubble upwardly through the molten metal around the other openings and the refining agent delivered therethrough in a stirring and mixing action beginning adjacent the bottom of the ladle.

摘要： A method for producing steels of high purity and low gas content in steel mills and steel foundries comprises melting the steel with the desired alloying components in a ladle, directing an inert gas and oxygen mixture to the ladle with the molten steel to decarburize the steel in at least one phase, and carrying out decarburization, deoxidation and fining in separate operational steps without disturbing the coherence of the entire process cycle. The apparatus for carrying out the method includes a converter for the decarburization of the steel in several phases permitting successively a treatment with an air inert gas oxygen mixture and pure inert gas in gas amounts greatly varying from each other. In addition, a ladle is required for fine-flushing the steel succeeding the converter. The converter mouth advantageously has a mechanism permitting temporary reduction of the converter opening area. The converter also has a gas volume control and injection holes permitting a variation of the different gases to be injected. Injection holes are advantageously provided with individual controls. A ladle for the finished melt is lined with basic or neutral refractory materials so that the ladle lining can furnish no oxygen to the melt. A tapping ladle for the finished melt is advantageously lined with dolomite.

摘要： A steel refining method of the type in which the steel is refined through an interfacial reaction between the molten steel in a vessel and a slag on the molten steel. The method simultaneously employs both of blowing of an inert gas into the molten steel from the bottom of the vessel to stir the molten steel by bubbling and blowing an inert gas from the upper side of the vessel into the zone on which the movement of the slag is dull. Consequently, the stirring effect on the molten steel is enhanced to promote the refining reaction. The inert gas can contain a desulfurization agent.
