Pouring & Cooling
浇注与冷却
标签：浇注, 冷却, 温度
浇注温度：青铜 1100–1180℃、黄铜 1000–1100℃。浇包预热干燥，浇注连续平稳、浇口杯保持满溢以防卷气。浇后不可立即开箱（急冷裂），厚大件需保温缓冷或埋砂冷却。落砂时机：铸件呈暗红色（约 500℃ 以下）再开箱清理。记录温度与速度，便于复现。
Pour temp: bronze 1100–1180℃, brass 1000–1100℃. Preheat and dry the ladle; pour steady and continuous, keep the cup flooded to avoid air entrainment. Do not open the mold early (thermal shock cracks); large thick parts need slow cooling in sand. Shake out when the casting is dark red (<~500℃). Log temp and rate for repeatability. ---
