摘要： This invention relates to a method of preventing, during the melt-reduction of Cr ore or iron ore, the scatter loss of the ore and coal at the time of charging. In the present invention, the ore and coal are charged down into a furnace from a shoot extended near a furnace port or connected to a furnace body. The ore and coal are charged down into the furnace while a gas is jetted outward of the shoot form nozzles disposed in the circumferential direction inside and near the tip of the shoot so that the raw materials can be charged more effectively while reducing the scatter loss.

摘要： A process for directly obtaining high Cr content melt by melt reduction of Cr starting materials such as Cr ore pellets, etc. is disclosed, which comprises using a furnace equipped with a bottom-blowing nozzle, a side-blowing nozzle, and a top-blowing nozzle, blowing an inert gas or the like through the bottom-blowing nozzle to form a projection on the molten metal surface, blowing an inert gas against the projection through the side-blowing nozzle to diffuse the molten metal into a Cr material-floating region in the slug for accelerating reduction of the Cr-containing material with C contained in the molten metal, blowing O2 for decarburization into the molten metal through the top-blowing lance, and blowing O2 for secondary combustion into slug to form a secondary combustion region mainly in slug, and strongly stirring slug by the side-blowing gas to give the heat produced by the secondary combustion to Cr ores with high efficiency, with keeping secondary combustion ratio at 0.3 or more for assuring the high secondary combustion.

摘要： A process for decarburizing high-Cr molten pig iron under atmospheric pressure in a short time with minimized Cr loss due to oxidation is disclosed. A fundamental feature of the process comprises top-blowing decarburizing O2 diluted with an inert gas through a top-blowing lance against high-Cr molten pig iron in a vessel and at the same time blowing an inert gas through a bottom-blowing tuyere to vigorously stir the molten pig iron. Another feature of the process comprises controlling a slag amount in the above-described decarburizing blowing to thereby depress Cr loss due to oxidation. A further feature comprises conducting a predetermined denitrification after the blowing to thereby economically produce low-nitrogen molten iron with depressed Cr loss due to oxidation.
