介绍用于液流型内孕育的浇注系统,可保证小粒状孕育剂加入金属流中直接进入型腔。图1浇注系统为在上箱中用芯3在同铸型结合时形成上部直浇口4,环形横浇口5和倾斜的内浇口8作成螺旋形。沿型芯轴制成通道6,用以在液流中供给孕育剂。金属浇入浇口漏斗1中,沿上部直浇口进 Introduced pouring system used for fluid inoculation, to ensure that small granular inoculant added to the metal flow directly into the cavity. Figure 1 casting system in the upper box with the core 3 in the same mold to form the upper sprue 4, the annular gate 5 and inclined gate 8 made spiral. Channels 6 are made along the mandrel for feeding the inoculant in the flow of liquid. Metal poured into the gate funnel 1, along the upper sprue into
