    摘要: A casting mold which is molded by heating mulled sand including a mixture of refractory molding sand particles, an inorganic water soluble binder and water, wherein the inorganic water soluble binder is made of a combination of a sulfate compound such as magnesium sulfate heptahydrate and a borate compound such as sodium tetraborate decahydrate. The casting mold is formed by baking the mulled sand in such a manner that at least part of the sulfate compound retains water of crystallization therein and the borate compound is once fused and then cured.

    摘要: Remelting/hardening treatment is carried out for a work by a remelting/hardening treatment apparatus including a torch for heating the work. First, the work is firmly placed in position in the remelting/hardening treatment apparatus and a temperature of the work is then measured by a temperature detector. When the measured temperature is lower than a lower limit temperature of a predetermined or particular temperature range, a level of output from the torch is lowered and a part of the work other than a part thereof to be treated is then preheated by the torch. Thereafter, the part of the work to be treated is subjected to remelting and hardening with the aid of the torch. Consequently, production of unacceptable works can be prevented reliably, since remelting/hardening treatment is not carried out at all while the measured temperature is lower than the predetermined or particular temperature range. Alternatively, a preheating operation is performed by the torch while an insufficiently preheated work is placed in position in the remelting/hardening apparatus. After completion of the preheating operation, the work is subjected to remelting and hardening in the same manner as mentioned above.

    摘要: The surface of a metal workpiece is remelted by a heat producing energy beam so as to form a molten metal layer thereon. While remelting the surface, a magnetic field is generated coaxially with the energy beam and is applied across the molten metal layer so as to cause the heat energy to flare and, thereby, produce a Lorentz force in the molten metal layer. By the Lorentz force, the molten metal is agitated. The heat energy and magnetic field are oscillated, or reciprocally moved, relative to the surface so as to cause a flow of the molten metal from the edges of the molten metal layer toward the center, thereby providing a uniform chilled layer thickness.
