离心铸造铜戒指案例

某工作室以失蜡石膏型离心铸造 8 克青铜戒指。蜡树每株挂 12 件，钢铃转速 350 rpm，合金 920℃ 浇注。离心力使薄壁花纹完整充型，成品几乎无冷隔。关键是石膏焙烧至 700℃ 并保温 2 小时彻底脱蜡，否则残留蜡气导致气孔。
A studio cast 8 g bronze rings via lost-wax plaster centrifugal casting. Twelve pieces per wax tree, centrifuge at 350 rpm, alloy poured at 920°C. Centrifugal force filled fine thin-wall details with almost no misruns. Key: burnout the plaster to 700°C and hold 2 h to fully eliminate wax, otherwise residual wax gas causes porosity. ---
