Abstract: A welding tool for a robot welds together a first component and a second component by using a metallic welding element disposed within a through-hole in the second component. The welding tool includes a welding torch attached to an arm, an element pusher that is attached to a distal end of the arm and disposes the held welding element between the welding torch and the through-hole and disposes at least a part of the welding element within the through-hole, a component pusher attached to the distal end of the arm and movable in an axial direction of a distal end of the welding torch, and a driving device that presses the component pusher against the second component. The element pusher is movable in the axial direction relative to the component pusher.

Abstract: With a device including a melting furnace (11) for melting metals to form a molten metal (M), a tilted cooling body (31) allowing the molten metal (M) delivered from the melting furnace (11) to be poured thereon from above, and a tilted cooling body vibrating mechanism (36) for imparting vibration to the tilted cooling body (31), this invention can produce metal slurry possessing fine spherical crystals efficiently and continuously.

Abstract: A molten Mg or Mg alloy is supplied into a mold, which is sheltered from the surroundings, from a pool in a tundish, which is shielded from the surroundings. An Mg slab or Mg alloy slab in the mold is drawn out to the outside from an outlet of the mold. A cooling medium is jetted onto the slab on an outer side of and in a vicinity of the outlet to cool the slab. A sealing gas is sprayed over an entire width of a free surface of the molten Mg or Mg alloy on an inner side of and in the vicinity of the outlet, to seal a portion above the entire width of the free surface of the molten Mg or Mg alloy, whereby preventing oxygen from flowing into the mold from the portion and preventing the cooling medium from running back to the mold side.

Abstract: A pouring apparatus for castings uses separate systems for supplying billets and delivering the semi-molten material, making it possible to readily modify the discharge flows and pressure. A pouring apparatus for castings that comprises solid material supply means for supplying solid material to a melting basin; heating means for heating the melting basin to semi-melt solid material supplied to the melting basin; a conveyance chamber provided adjacent to the melting basin; and delivery means for discharging, from a discharge nozzle, semi-molten material conveyed from the melting basin to the conveyance chamber.

Abstract: A method of grain refining cast magnesium alloy includes adding to a magnesium alloy melt containing aluminum and manganese, pure carbon powder, or a carbon source in combination with niobium pentoxide or vanadium pentoxide.

Abstract: An apparatus for the production of a platelike metal material includes a cooling unit for cooling a molten metal to form a metal slurry containing a solid phase, a pair of coarse rollers for cooling the metal slurry and, at the same time, rolling it to thereby give rise to a continuous, solidified, platelike metal material, and a cutting mechanism for cutting the continuous, solidified, platelike metal material into platelike metal materials of a stated length. Thus, platelike metal materials containing numerous uniform spherical crystals are obtained.

Abstract: A casting method includes the steps of cooling a molten metal to form a metal slurry containing a solid phase, cooling the metal slurry to form a solid metal material and heating the metal material to a semi-melted metal material and supplying it into a mold. A casting apparatus includes a first device for cooling a molten metal to form a metal slurry containing a solid phase and a second device for cooling the metal slurry to form a solid metal material. The metal material is then heated to a semi-melted state and the resultant metal material is poured into a mold. A method for manufacturing a metal material being heated to a semi-melted state and then supplied into a mold, includes the steps of cooling a molten metal to form a metal slurry containing a solid phase and cooling the metal slurry to form a solid metal material.
