摘要： Desulfurization is carried out by blowing CaO into molten iron, and a gas mixture of an inert gas and a hydrocarbon gas is used as a carrier. The ratio of the hydrocarbon gas to the desulfurizing agent is maintained in the range of from about 2.0 to about 50 Nl/kg. This desulfurizing method improves the desulfurization efficiency of the desulfurizing agent, increases the productivity of the desulfurizing process, and reduces the amount of slag generated in the desulfurizing process. Alternatively, a desulfurizing flux is blown into the molten iron together with a carrier gas comprising a gas mixture of an inert gas and a hydrocarbon gas or an inert gas alone at the start of desulfurization. The hydrocarbon gas in the carrier gas is increased, is added, or the unit gas is replaced by the hydrocarbon gas at adequate timing, whereby the desulfurization efficiency is improved.

摘要： A method of repairing a refractory lining of a vessel lined with refractory by flame gunning process, in which a patching material consisting of refractory particles and carbonaceous fuel powder is flame-gunned together with an oxygen containing gas to fuse or semi-fuse the refractory particles in a region surrounded by high-temperature flame and struck against the surface of the refractory lining to produce a deposit layer of the refractory particles, is disclosed. In this method, a patching material having a higher mixing ratio of the fuel powder or only the fuel powder is flame-gunned at an initial stage of the repairing and subsequently patching materials, in which the mixing ratio of the fuel powder is lowered stepwise, are flame-gunned in order with the progress of the repairing, during which a blow rate of the oxygen containing gas is controlled in accordance with the change of the mixing ratio of the fuel powder in the patching material.

摘要： An apparatus for removing non-metallic foreign matter in a molten steel includes a tundish and a coil device. The tundish is an intermediate container receiving the molten steel from a ladle and feeding a purified molten steel by removing the non-metallic foreign matter in the molten steel. For removing the non-metallic foreign matter, the tundish has a swirl flow bath and a floatation bath. In the circumference of the swirl flow bath of the tundish, a coil device is arranged for flowing the molten steel in the swirl flow bath in swirl fashion. The tundish and the coil device are formed separately and constructed for relative movement to each other. The molten steel in the swirl flow bath of the tundish is flown in swirl fashion in the horizontal direction by a magnetic field generated by the coil device. At this time, the molten steel forms a parabolic concaved surface. The non-metallic foreign matter in the molten steel is forcedly floated up on the parabolic surface portion of the molten steel, which is removed by an appropriate means. The molten steel thus purified flows into the floatation bath from the swirl flow bath. With the static flow in the floatation bath, the residual non-metallic foreign matter floats up. The purified molten steel is poured into the mold through the bottom of the floatation bath.

摘要： A method is disclosed for accurately detecting an outflow of a slag into a stream of a molten steel when the molten steel is poured from a first vessel such as a refining furnace or a ladle into an intermediate vessel such as a ladle or a tundish through a melt-discharging hole or a nozzle. At that time, an inert gas is fed into the stream of the molten steel in the nozzle through a side portion of the melt-discharging hole or the nozzle, and the detection is made based on a change in a flow rate of the inert gas sucked into the stream of the molten steel and/or in a back pressure.
