| PURPOSE: To obtain a slurry having fine and uniform non-dendritic crystal grains by rapidly cooling molten metal to half-solidified state while flowing in an inclining surface and thereafter, holding the slurry to the overheat condition. CONSTITUTION: The molten metal (m) in a molten metal holding furnace 1 is held to the temp. near the liquids. This molten metal (m) is poured on a cooling plate 2.

| PURPOSE: To separate including gas and to obtain a cast ingot without defect by stirring semi-solidified metal slurry in a tiltable mixing vessel while adjusting the temp., slowly tilting the vessel introducing the slurry into a shaping mold providing an exothermic material at the upper part and a chill block at the lower part and slowly casting. CONSTITUTION: While forcedly cooling and stirring molten metal or alloy, the semi-solidified metal slurry having the form dispersing the fine solid-phase particles in the liquid-phase is manufactured. This slurry is shifted into the tiltable mixing vessel 1 and introduced in the condition of a specific solid-phase ratio by a heater 5 and a rotary stirrer 2. The rotary stirrer 2 is pulled up from the mixing vessel 1 by a lifter 15 and reserved. A trunnion 4 is slowly rotated by a motor for tilting through a speed reducer and by tilting the mixing vessel 1, the slurry is flowed down to a pouring passage 6 and shifted to the ingot mold 7. As the slurry is quickly cooled from the lower part by the chill block 8 while delaying the solidification by the effect of the exothermic material 9 provided in the mold 7, the including gas is floated up and separated and also, while preventing the development of shrinkage cavity, the slurry is solidified.

Further, the cooling wall 2' provides cooling jacket 2 and is cooled through cooling medium 11. The dendritic crystal generated from the molten metal 8 in this gap is crushed with the shearing force based on rotation of the rotator 1 to make this fine grains having non-dendritic primary crystal. Then, it is desirable to adjust the above gap to the optimum with a hydraulic cylinder 6 by detecting loading torque of the rotator 1. The semi-solidified metal 10 obtd. with this, is continuously discharged from a discharging hole providing the refractory wall 5' at lower part of the gap. COPYRIGHT: (C)1991,JPO&Japio | ||||||

| PURPOSE:To reinforce a material and to simplify a process by enabling its forming in a block shape as well by giving a large deformation with less deforming energy simultaneously with rapidly cooling the material of a molten state in order to manufacture a reinforced stock by refining the crystal of the crystalline material of metal, etc. CONSTITUTION:The material in a molten state formed in a thin layer shape on a substrate 2 is rapidly cooled toward the upper part from the thin layer lower part coming into contact with the substrate 2 with rapidly radiating a heat in the direction of its touching substrate and solidified by freezing accompanied by the refining of the crystal, the refining of the deposit layer, the enlargement of the solid solution limit, etc. Simultaneously therewith a strong deformation is given to this solidifying material by simultaneously giving a high pressure and large shearing force by a pressing means. As a result the re-crystallization is prevented with the crystal grain of a crystalline material 1 being parted and refined, a fine crystal structure is formed and the thin film 5 of a reinforced reinforcing stock is formed on the substrate 2 with a fine crystal structure being formed. | ||||||
