 note = {二室型加圧鋳造システムにおける鋳造圧の立ち上がり速度は,鋳型内のアルゴンガスがいかに速く排気されるかにかかっている.本研究では,この鋳造システムにおける鋳造時の鋳型空洞の圧力変化を測定し,鋳型の温度と大きさが鋳造圧の立ち上がり速度および一定時間経過後の鋳造圧に及ぼす影響を検討した.さらに,改良型クルシブルを提案し,それが鋳型空洞の圧力変化に及ぼす影響も検討した.その結果,高い鋳型温度と大きい鋳型では鋳造圧の立ち上がり速度が顕著に小さかった.クルシブルの形状については有意な影響は認められなかった.ただ,従来型より改良型のクルシブルのほうが高い鋳造圧が作用した., In a two-chamber pressure-casting system, the rate of casting pressure increase depends on the exhausting rate of argon gas in the mold. The purpose of this study was to measure the pressure change in a mold cavity after the start of casting and to investigate the influence of mold temperature and thickness on the initial rate and later value of casting pressure. Moreover, a new casting mold with an experimentally improved crucible was proposed and its influence on the casting pressure was also investigated. Regardless of crucible condition, the initial rate of casting pressure decreased with mold temperature and thickness. Although the difference in crucible condition did not significantly influence the initial rate, the improved crucible increased the later value of casting pressure.},
