摘要： PURPOSE:To prevent the condition that the supply of a powdery body such as a desilicating or dephosphorizing agent can not be performed due to the reflux of molten pig iron or steel into the nozzle of a lance resulting in clogging the nozzle with the powdery body, when the powdery body is injected into the molten pig iron or the like, by thrusting pressurized gas in the lance through its upper part. CONSTITUTION:A desilicating or dephosphorizing agent A in a lift tank 1 is fed through a carrying pipe 2 into a lance 3 by gaseous pressure and injected through the nozzle 31 of the lance into molten pig iron or the like inside a ladle 4 to perform prerefining such as desilicating or dephosphorizing. Hence, a pressing nozzle 5 is inserted into the upper part of the lance 3 to inject pressing gas for raising the pressure of spraying the powdery body through the nozzle 31 of the lance. As a result, the reflux or invasion of the molten pig iron into the lance 3 is prevented so that the clogging of the lance 3 with the invasion of the molten pig iron which would make the injection of the powdery body impossible or damage the lance 3 in a short time can be inhibited. On this occassion pressure inside the carrying pipe 2 is detected by a sensor 6, the detected value is amplified by an amplifier 61, and the opening rate of a pressure- regulating valve 51 for the pressing nozzle 5 is properly controlled so as to protect the molten pig iron from being cooled by injecting an excess amount of pressing gas through the pressing nozzle 5.

摘要： PURPOSE:To prolong the life of a vessel for molten pig iron and to reduce the number of lining the vessel while suppressing a heat loss from an iron plate, in the pretreatment of the molten pig iron such as desilicating, by using double- layered formed bricks having high durability and low thermal conductivity as the lining of the vessel for the molten pig iron. CONSTITUTION:The whole inside surface of an iron plate A covering the entire periphery of a torpedo car 5 except its opening 5a to receive molten pig iron is lined with castable B in the same way as a conventional manner. The further inward part is lined with roof-forming double-layered bricks C at the ceiling part, with double-layered formed bricks D for a slag line at the part estimated to correspond to the slag line during reserving the molten pig iron and with pieces of bricks E for the part of the molten pig iron at the other part, respectively. The bricks C and D are those formed by integrating the two layers of a refractory material alpha excellent in durability to the pretreatment of the molten pig iron and another refractory material beta having thermal conductivity below 3Kcal/m.h. deg.C, and applied in a manner such that the layer alpha is located at the working side while the layer beta is located at the side of the iron plate A.

摘要： PURPOSE:To practically use converter-slag as pig making-raw material and to reduce the cost in the process of manufacturing pig and steel, by the following method in which the phosphorus in moten pig enriched by utilizing converter- slag in pig making-process is removed, before the pig is charged into a converter. CONSTITUTION:For the molten pig tapped from a blast furnace, dephosphorizing treatment is carried out before the pig is charged into a converter, thereby it is able to controll the enriched phosphorus in the molten pig corresponding to the used amount of converter-slag. In order to dephosphorize the molten pig, desiliconizing treatment is achieved before the dephosphorization of the molten pig tapped from a blast furnace. This is essential to elevate the dephosphorizing efficiency. The desiliconizing treatment may be carried out on a casting bed, in a mixer or a ladle. Then, soda ash is preferred to caustic lime for dephosphorizing the molten pig, because amount of generated slag and the loss of Fe and Mn are decreased, and additionally the high efficiency for dephosphorizing and desiliconizing is obtained. Next, the dephosphorized molten pig is charged into the converter.

摘要： PURPOSE: To make the tendency toward unidirectional solidification much surer and produce a longitudinally short steel ingot of superior internal quality by packing heat resistant powder in the groove provided along the joined part of the outside circumferential part on the root end part side of a mold flask body and a molding board thereby shutting off the flow of the atmospheric air.
CONSTITUTION: In a longitudinally short mold consisting of a molding board 1, a molding flask 2 and a heat insulating material 3, an outside flask 5 of an iron sheet is provided in a shelf shape on the board 1 slightly spaced from the mold 2 in such a way as to encircle the mold 2, thereby forming a groove around the root end side of the mold 2. Heat resistant powder 6 such as sand or castable refractories is packed and contained in this groove. The atmospheric air side of the gap S2 produced between the board 1 and the mold 2 after teeming of molten steel is shut off by this powder 6, and the flow of the atmospheric air produced by the gaps S1, S2 is prevented.

摘要： PURPOSE:To recover phosphorus, vanadium, etc. in a high yield from slag formed, by adding a slag forming agent with an alkali metal carbonate base to pig iron desiliconized by a primary treatment to carry out the secondary treatment of the pig iron. CONSTITUTION:The slag formed by the secondary treatment of the pig iron after the primary treatment, is cooled to solidify and then crushed to yield lump-shaped slag, which is eluted with hot water. After removae of the residul such as SiO2, Fe from the extrate, Fe ions such as FeSO4 are added to the extrate to separate S as FeS by filtration. Subsequently, the filtrate is concentrated to precipitate Na2CO3crystals, which are used as a part of soda ash to be used for the secondary treatment of the pig iron. To the filtrate after separation of the Na2CO3 precipitate, a calcium compound such as CaO is added to precipitate P as Ca3(PO4)2, which is separated by filtration. To the extrate after the filtration, an NH4 compound such as (NH4)2SO4 is added to precipitate NH4VO3. The NH4VO3 precipitate is heated and decomposed to form V2O5, which is reduced by Al to form pure vanadium.
