摘要： PURPOSE:To perform reduction by a small amount of a carbonaceous substance by generating a large amount of excessive gasifying heat, in a lance for use in preparing alloyed iron according to an iron bath coal gasifying process, by separately providing a nozzle for blowing in O2 for mainly aiming secondary combustion. CONSTITUTION:As a lance for preparing alloyed iron by melting and reducing a metal ore or metal oxide by utilizing an iron bath coal gasifying process, a non- immersion type top blowing perforated lance is used. This lance has the following structure. That is, one or more of a nozzle a1 for blowing a particulate material comprising a carbonaceous substance or a metal ore is provided to the center while plural nozzles a2 each for blowing a gasifying agent such as O2 are mounted to the periphery thereof and, herein, nozzles a3 for blowing O2 for secondary combustion are further provided on the same circumference of the nozzles a2 or to the outside thereof. By this structure, because O2 for mainly aiming secondary combustion can be blown apart from O2 as the gasifying agent, a large amount of excessive gasifying heat can be generated and a large amount of a metal ore can be melted and reduced by a small amount of a carbonaceous substance.

摘要： PURPOSE:To economically manufacture a nickel alloy steel by blowing a carbonaceous material and a gasifying agent into a molten iron bath, charging nickel matte into the bath, and desulfurizing and dephosphorizing the resulting crude ferronickel. CONSTITUTION:A carbonaceous material 3 such as coal and a gasifying agent 4 such as oxygen are blown into a molten iron bath 1 stored in a melting furnace 2 from a lance 5 to carry out gasification, and the produced gas is recovered through a liftable skirt 9 and a hood 10. Nickel matte 6 is then added to the molten iron 1 from bottom blowing nozzles 8 and the lance 5 or a flux charging inlet 11. The matte 5 charged into the furnace 2 receives heat rapidly in the iron bath and is melted, and the molten matte is separated into Ni and S. The Ni is solubilized in the iron bath 1, forming molten ferronickel. Part of the S is absorbed in the bath 1 and most of it is absorbed in slag. The molten ferronickel as a base metal in the furnace 2 is desulfurized, dephosphorized and decarburized to manufacture a nickel steel.

摘要： PURPOSE:To prevent economically and highly practically a nitrogen absorption of molten steel, by closing a sealing device of a converter open port and a suction damper to stop gaseous N2 sealing around the port and a purging of waste gas in the converter during the period from the beginning of reduction to finish. CONSTITUTION:At the decarbonization refining of high Cr steel, a hood 4a is lifted to release a converter open port 2a, and a suction damper is opened properly. A top-blown lance is inserted into the refining converter 2 from the port 2a to perform an oxygen top-blowing, and a purging of waste gas in the converter is performed by sealing the circumference of the port 2a with gaseous N2 to prevent an occurring of explosion of gaseous CO. At the last period of decarbonization or from the beginning of reduction period at the latest, the hood 4a is descended to close the port 2a, and the damper 5 is full closed to stop the sealing by gaseous N2 and the purging of waste gas. Gaseous Ar is supplied continuously from a tuyere 1 after that. In this way, the amount of gas in the converter is decreased, and an entering of air is prevented even after the last period of the decarbonization, and the absortion of nitrogen of the molten steel is prevented by keeping the partical pressure of the N2 in the converter in a low press.
