摘要： Precision casting of titanium or titanium alloy includes establishing molten metal by induction heating in an assembly formed with water cooled copper segments disposed circlewise on the inside of an induction coil in a state insulated from each other and casting the molten metal into a permeable mold by vacuum casting. The precision casting method uses apparatus including an induction coil, an assembly formed with the aforementioned copper segments, an arrangement for feeding a base metal from the under side thereof and a permeable mold into which the molten base metal in the assembly is transferred by vacuum casting. It is possible to obtain precision castings of metal having high melting points and high actvitiy such as titanium, titanium alloy or the like.

摘要： Molten metal melted in a levitation melting furnace is cast through a suction pipe immersed therein from above into a mold having a gas permeability in a double-structure mold chamber arranged directly above the melting furnace. The metal is levitation-melted in an inert atmosphere under atmospheric pressure. An outer mold chamber of the double-structure mold chamber is joined to the levitation melting furnace. Pressure in the outer mold chamber and in an inner mold chamber of the double-structure mold chamber and in an upper space in the levitation melting furnace is reduced to below atmospheric pressure. The suction pipe arranged in the inner mold chamber and communicating with the mold therein is immersed into the molten metal. The molten metal is cast into the mold under an increased pressure by blowing an inert gas into the upper space in the melting furnace. The inner mold chamber is raised, thereby pulling out the suction pipe from the molten metal. The outer mold chamber is raised after being returned to atmospheric pressure to separate from the melting furnace.

摘要： A levitation melting method and device through which a material having various configurations can be melted through efficient induction heating. First, a starting material(WB), whose outer diameter has been adapted to the inner diameter of a crucible(13), is inserted in crucible(13). The crucible(13) is shielded with argon gas, thereby starting the melting of the material(WB) to molten metal(WM). Subsequently, a suction tube(33) of a mold(31) is inserted into the molten metal(WM) for drawing a part of molten metal(WM) up into the mold(31) for casting. After part of the molten metal(WM) is drawn up, a sliding cover(15) is slid such that a material holder(19) is positioned right above the crucible(13). By opening a sliding plate(35) of the material holder(19), material pieces(WS) are inserted from the material holder(19) into the molten metal(WM) left in the crucible(13). Since gaps in the material pieces(WS) are filled with the molten metal(WM), a dense bulk is formed which is to be melted through induction heating.

摘要： A reactor for iron making having an upper gas blowing nozzle, a lower gas blowing nozzle, and an iron scrap charging inlet. A vertical shaft is installed directly above the inlet at the top part of the reactor. A mechanism is provided in the lower end of the vertical shaft for controlling charging of the iron scrap to the reactor. A by-pass tube is connected between the top part of the reactor and a gas inlet in the vertical shaft directly above the mechanism for controlling the charging of iron scrap and permits exit of high temperature exhaust gases from the reactor and introduces the exhaust gases to flow through the iron scrap in the vertical shaft to pre-heat the same. Structure is provided in the by-pass tube for introducing oxygen gas or air into the high temperature exhaust gases to react therewith and generate further heat. The structure can comprise a nozzle. The mechanism for controlling charging of iron scrap can include a damper positioned immediately above the inlet in the top part of the reactor which is movable to open and close the vertical shaft together with a stopper positioned above the damper and movable to open and close the vertical shaft. Certain amounts of iron scrap can thereby be charged to the reactor by sequential openings and closings of the damper and the stopper.

摘要： A method of melting iron scrap using an arc furnace with reduced electric power consumption.In one of a pair of vessels which are arc furnace bodies, melting of the scrap by heat of arc is carried out while a carbonaceous material and oxygen-containing gas are introduced therein to cause oxidation of C to CO to make use of the oxidation heat. Thus formed hot exhaust gas containing CO is introduced to the other vessel of the pair and oxygen-containing gas is added thereto to cause oxidation of CO to CO.sub.2 thereby heating the scrap loaded in the vessel. Melting is further continued by changing the roles of the two vessels to each other.Generation of the CO-containing hot gas can be performed in a separately installed gasification furnace.
