摘要： It is an object to provide a gas cupola for melting a charging material efficiently by a combustion flame of a combustion burner. The gas cupola includes a furnace body having a melting chamber 10 and a molten metal discharge port 11 for discharging the molten metal and a plurality of combustion burners 4 forming a combustion flame 41. The combustion burner 4 melts the charging material 2 in the melting chamber 10 by ejecting the combustion flame 41 to the charging material 2 in the melting chamber 10. Each combustion burner 4 generates a hollow shaped melting portion 42 at the charging material 2 of the melting chamber 10 by the combustion flame 41 ejected from each combustion burner 4. In the cross sectional view of the furnace body 1 taken along a horizontal direction, the combustion burners 4 are arranged so that the adjacently positioned two hollow shaped melting portions 42 overlap with each other. When the charging material 2 is melting, each hollow shaped melting portion 42 communicates with the molten metal discharge port 11.

摘要： A partition member having partition walls arranged in a lattice is disposed in the vicinity of an upper surface of a molten metal mass. The upper surface is divided by the partition walls into a multiplicity of segmental surfaces. A forming starter member is brought into contact with the partition member so that the molten material adheres to a starter surface of the forming starter member, and is then separated from the partition member. The molten metal is drawn from each of the segmental surfaces, and the drawn metal is solidified to form a piece which has a cross sectional shape corresponding to the shape of the starter surface. With the use of forming starter members having respective starter surfaces which are different in shape from each other, it is possible to form pieces having various cross sectional shapes which correspond to the shapes of the starter surfaces.

摘要： A vacuum casting apparatus secures gas tightness of the die cavity without welding together a straight-tubular stalk and a flange or flanges, thus permitting an excellent quality casting. A flange is mounted on an outer periphery of a stalk, and secured between a gas-tight chamber and a die, forming a recess bounded by the die, a surface of the flange, and an outer surface of the stalk. The space inside the chamber is evacuated to a first degree of vacuum so that molten metal is withdrawn into the stalk and overflows the end of the stalk, and flows into the recess. Molten metal in the recess cools and solidifies to form a gas-tight seal between the stalk and the flange. Then, the space inside the chamber is evacuated to a second degree of vacuum and molten metal is withdrawn through the stalk and into the cavity of the die.

摘要： A suction casting apparatus is disclosed, which comprises a ventilating casting die, a chamber box and a surface peat for supporting the casting die and chamber box. The surface plate has a a through hole for passing a stalk therethrough, and its surface is formed with grooves which extend from the through hole to an area outside a die mounting area and inside a chamber box mounting area. External air entering through a sealed clearance between the surface plate and the stalk and combustion gas generated from the casting die are quickly led through the grooves into the chamber inner space to be quickly exhausted to the outside.
