| 内容記述 | In this paper an improved method for the accuracy and the castability of the castings made with chromium-cobalt-nickel base alloys was described. Their restorations of crowns or bridges are difficult to set on the patient, which have casting shrinkage from 1.8 percent to 2.4 percent and high melting temperature above 1100℃. In this study, they were produced by the mold kept at low temperature. The molds were prepared by cooling at 200-400℃ in the furnace, after the amount of graphite containing the investments were burnt out at 800℃ for half-hour period. Dimensional changes of the investment keeping at 200-400℃, after it was heated at 800℃, were relatively magunitude than that of during heating. The castings made by means of low temperature mold used with phosphate bonded investments and linning Kaowool sheets in place of asbestos ribbon, produced the best fits. The accuracy of castings were influenced by the kinds of Kaowool sheets. The castability decreased by low temperature mold, were able to recover by means of forming the casting crucible to acute angle and rising the temperature of molten metals. | |||||||
