摘要： A method for preparing low-cost clean steel includes steps of: preliminarily desulfurizing iron melt: preliminarily desulfurizing in an iron melt channel during blast furnace tapping and during iron folding in an iron folding room, adding a desulfurizing ball into the iron melt during the blast furnace tapping or the iron folding; dephosphorizing and controlling sulfur: dephosphorizing and controlling sulfur during converter steelmaking, in such a manner that P≦0.014% and S≦0.004% during tapping; rapidly dephosphorizing by slag-forming: rapidly dephosphorizing by slag-forming during converter tapping, at a converter end point, controlling a C content at 0.02˜0.10%, adding a dephosphorizing ball through an alloy chute during the converter tapping, blowing argon and stirring at the same time; purifying steel melt during RH refining: adding a purifying ball at a late stage of the RH refining when a vacuum degree is at 66.7˜500 Pa; and continuously casting with whole-process protection.

摘要： A method, an installation and a nozzle for suppressing the generation of iron-containing vapor during filling or emptying of a container for an iron-containing metal melt with the aid of CO2 snow, a CO2 snow jet being applied by means of the nozzle dispersing in a substantially planar manner onto a surface of an iron-containing stream which is poured into or out of the container.The invention consequently at least partially solves the technical problems outlined in connection with the prior art. In particular, a device is proposed which allows cost-effective and space-saving suppression of the generation of iron-containing vapor during the filling or emptying of a container with the aid of a reduced CO2 snow quantity.

摘要： According to this method, the adjuvant is delivered from a supply means (12) placed above the casting bowl (4), a target zone (Z) for the theoretical passage of this adjuvant is chosen, said zone lying downstream of the supply means (12), and the actual passage of the adjuvant in the target zone (Z) is detected optically, by means of at least one camera (14). At least one image of the target zone (Z) is taken by means of the or each camera (14), this image being taken with an exposure time short enough to identify the density of particles of this adjuvant that are present in the or each image, and a warning signal is generated if the measured particle density is below a predetermined value.

摘要： The method introduces additives into a flowing melt or fluidized metallic/ceramic powder media in a pulsed high pressure manner. The nozzle needle of at least one nozzle is variable and highly precisely moved for the introduction by means of a device and in such a way that additive is dosed exactly in relation to the volume flow of the medium. The pulsating additive stream is injected into the flowing medium by at least one well-aimed nozzle opening. The additives are dosed by means of a pressure that can be variably adjusted by pulse width and pulse frequency. The desired homogenous distribution is obtained by the penetrating injection jet.

摘要： A vertical first stream of molten metal flows from a ladle into the tundish of a continuous casting apparatus. A second stream composed of solid, particulate alloying ingredient and a non-oxidizing carrier gas is directed into the first stream with a nozzle. The two streams each have unenclosed parts exposed to the atmosphere surrounding the ladle and the tundish. The nozzle is cooled with a non-oxidizing gas flowing through a nozzle cooling jacket and exhausted at the outlet end of the nozzle. The nozzle interior has a converging downstream end portion for converging the second stream just before it leaves the nozzle.

摘要： An elongated, vertical conduit has an upper end, communicating with the bottom opening in an upper container or ladle, and an open lower end disposed above the top surface of a bath of molten metal in a lower container or tundish. A descending stream of molten metal is directed from the conduit into the bath. A shroud encloses the conduit and the descending stream. The pressure within the shroud is lower than the outside pressure and is regulated. A mixture of transport gas and solid, particulate alloying ingredient prone to excessive fuming is injected into the descending stream within the shroud.
