摘要： An apparatus for continuous casting of magnesium billets or slabs using an electromagnetic field, and a method thereof compensates small solidification latent heat of magnesium, controls a solidification speed, and stirs molten metal within a mold via an electromagnetic field, thereby enabling continuous casting. The apparatus comprises a mold for continuous casting an as-cast billet or slab, a coil positioned outside the mold and adapted to allow electric current to be applied thereto, and a cooling nozzle positioned outside the mold and the as-cast billet or slab. During casting, electric current having a frequency of 2 ~ 1,000 D or electric current of 50 ~ 10,000 A having a frequency of 200 ~ 200,000 D is applied to the coil. A magnesium billet or slab having enhanced inner quality can be produced at a high casting speed without surface defects by applying a low frequency or high frequency electromagnetic field to the mold during continuous casting of magnesium.

摘要： The present invention relates to an apparatus and method for manufacturing molten iron. The method for manufacturing molten iron includes producing a mixture containing iron by drying and mixing iron-containing ore and additives; passing the mixture containing iron through one or more successively-connected fluidized beds so that the mixture is reduced and clacined to thereby perform conversion into a reduced material; forming a coal packed bed, which is a heat source in which the reduced material has been melted; charging the reduced material to the coal packed bed and supplying oxygen to the coal-packed bed to manufacture iron; and supplying reduced gas exhausted from the coal-packed bed to the fluidized bed, wherein in the conversion of the mixture to a reduced material, oxygen is directly supplied and combusted in an area where reduced gas flows to the fluidized bed. The apparatus for manufacturing molten iron of the present invention uses this method for manufacturing molten iron. Through use of the present invention, the reduced gas passing through the fluidized beds may be improved, and cohesion of the iron-containing fine ores may be prevented.

摘要： An apparatus for preventing bulging of both edges of a strip while preventing contamination of a roll surface in a twin roll strip caster including a meniscus shield (5) and a plurality of weirs (12). The apparatus comprises: first chambers (60) arranged at both sides of the meniscus shield (5) in a longitudinal direction parallel to the casting roll (1) and having inlet and outlet ports for non-oxidizing gas; second chambers (80) each assembled to an underside in each of the first chambers (60) in a communicating fashion for receiving non-oxidizing gas from the first chambers (60), and including a plurality of holes (81) formed in an inclined face thereof corresponding to an outer peripheral face in each of the casting rolls (1 and 1a) in a longitudinal direction of the each casting roll (1or 1a); and passages S formed between the meniscus shield (5) and the second chambers (80) and reaching the gas outlet ports of the first chambers for allowing contaminated gas containing evaporated metal components and non-oxidizing gas injected from the second chambers (80) to be outwardly exhausted.

摘要： This invention relates to a production method of a directional electromagnetic steel sheet used as a core material for a transformer, a motor, a generator, and other electromagnetic appliances. A component system is designed so that a directional electromagnetic steel sheet of a conventional system is heat-treated at approximately 1,250 to 1,300 DEG C which is the same slab heating temperature as in the treating condition of general steels, and is then hot rolled. In this way, the present invention only requires operation in existing production processes without reinforcing the installation or establishing a new one, and stably forms secondary recrystallization in the (110) [001] orientation by securing stably a grain growth restriction force. Therefore, the present invention provides an improved directional electromagnetic steel sheet production method in which a preliminary annealing step is omitted, decarbonization/annealing is carried out at an intermediate thickness and machining energy at a final rolling step is lowered, so as to obtain stable magnetic characteristics. The gist of the present invention resides in a method of producing a directional electromagnetic steel sheet comprising hot rolling, after heating, a slab having a composition consisting, in terms of wt.%, of 0.035 to 0.050 % of C, 2.9 to 3.3 % of Si, not greater than 0.015 % of P, 0.011 to 0.017 % of dissolved Al, 0.0080 to 0.012 % of N, not greater than 0.007 % of S, 0.06 to 0.18 % of Ni+Cr, not greater than 0.32 % of Mn satisfying the condition of Mn/S: 20 or more, not greater than 0.6 % of Cu satisfying the condition Cu/Mn: 1.5 or more, and the balance of Fe, at 1,250 to 1,320 DEG C, regulating the rolled sheet to a final thickness by two cold rolling operations including an intermediate decarbonization/annealing without conducting annealing of the hot rolled sheet, then effecting intermediate annealing and annealing using MgO as the principal component, applying a separating agent, and thereafter conducting final finish annealing to produce a directional electromagnetic steel sheet having excellent magnetic characteristics.
