摘要： Disclosed herein is a method of reducing slag, including the steps of: examining the components of slag to be reduced, and setting a target composition ratio after reduction; determining the mixing ratio and input amount of a complex reducing agent of a plurality of reducing agents in accordance with the set target composition ratio to determine the complex reducing agent; and supplying the complex reducing agent into molten slag to reduce the slag. The method is advantageous in that the reduction efficiency of slag can be maximized, various kinds of reducing agents can be efficiently used, and the recovery amount of valuable metals can be increased, thus reducing cost.

摘要： In a method of treating alloyed carbon-containing iron melts for the production of steel, whereby a carbon-containing iron melt is subjected in a metallurgical vessel to a decarburization by addition of oxygen and a part of the metallic alloying elements is slagged, whereby the metal melt is withdrawn from the metallurgical vessel while the unreduced slag remains in the metallurgical vessel and then the metallurgical vessel is filled with a new charge or iron melt and subjected anew to a decarburization process so that the loss of expensive metallic alloying elements as a result of decarburization is small because of the slagging. This is achieved in that without intervening removal of the slag, the slag is increasingly, saturated with metal oxides which derive from the melt and such that with increasing saturation the slagging of the metallic alloying elements is increasingly counteracted.
摘要翻译：在用于生产钢的合金含碳铁熔体的处理方法中，通过添加氧将含碳铁熔体在冶金容器中进行脱碳，并且将一部分金属合金元素排渣，将金属熔体从冶金容器中取出，而未还原的渣保留在冶金容器中，然后冶金容器中填充有新的电荷或铁熔体，并重新进行脱碳过程，从而导致昂贵的金属合金元素的损失由于造渣，脱碳量很小。这是通过没有间歇地去除炉渣来实现的，炉渣越来越多地被来自熔体的金属氧化物饱和，并且随着饱和度的增加，金属合金元素的结渣越来越多地被抵消。

摘要： The invention is directed to a process for dehydrating and recycling back into a BOF converter wet BOF scrubber sludge to produce a steelmaking revert having an improved flow rate when handled in a recycle stream. Wet sludge is combined with hot BOF slag to provide a slag/sludge mixture. The wet sludge causes the mixture to have a moisture content greater than 10% water by weight, and the hot slag, having a temperature below the molten liquid state, vaporizes the water in the mixture and reduces the moisture content to about 4% water by weight or less. The dehydrated mixture has improved flow rate properties when it is recycled as a steelmaking revert.

The burner/injector may be arranged as a simple liquid-cooled combustor permanently mounted through the furnace wall or roof, and may be equipped with single or multiple channels for injection of solid material and high velocity oxidizing gas. Separate injecting lances for high velocity oxidizing gas and/or solid carbonaceous fuel may be mounted on the furnace.

摘要： A method of melting and refining metals by high-temperature impinging combustion products generated by a single or multiple oxy-fuel or fuel/oxygen/air combustors that direct a flame towards a predetermined area of scrap to be melted. Once a portion of charged scrap contacted by the flame or flames is melted, an injection of solid carbonaceous fuel is initiated, preferably through a combustion tunnel of at least one of the combustors. High velocity oxygen is directed, simultaneously with carbonaceous material, through at least one dedicated nozzle toward injected solid carbonaceous fuel to mix with this fuel and to generate CO, which is capable of forming foamy slag. Optionally, a supersonic stream or multiple streams of additional oxygen is also directed toward the iron-carbon melt to initiate rapid melt refining.

摘要： A method of controlling slag coating in a steel converter in which slag is left in the converter after tapping, and a slag solidifying agent is added to the slag to form a coated slag which is used to coat the bottom and/or side wall surface of the converter. The method is performed bya) examining the composition of the slag at the tapping time;b) determining, based on the examined slag and through an equilibrium calculation using thermodynamic data, the amount of solidifying agent per unit weight of the slag necessary for maintaining the liquid volume fraction of the coated slag to a value not greater than about 40% at the planned tapping temperature of the next charge of steel;c) determining the amount of charge of the solidifying agent based on the calculated required amount of the solidifying agent and the amount of the slag remaining in the converter; andd) adding the calculated charge of the solidifying agent to the slag after tapping, to form a coated slag.

摘要： A method of degassing and decarburizing molten stainless steel in a vacuum, which molten steel is produced in a steel making furnace. Molten steel is foamed in a vacuum tank. Before foaming the [N] (%) in the molten steel is increased. The foam is produced by denitrification of the steel during vacuum degassing. Oxidizing gas is blown through a top-blow lance onto the surface of the steel in a vacuum tank, causing the reaction C+1/2O.sub.2 .fwdarw.CO to decarbonize the steel. Temperature decrease of the molten steel is resisted by combustion of CO produced by the reaction of C+1/2O.sub.2 .fwdarw.CO.
