摘要： PURPOSE:To improve the effect of inoculation and to prevent entry of foreign matter by passing a molten metal through the through-hole disposed in the midway of a runner and provided in a central part. CONSTITUTION:An in-mold inoculant 7 having a through-hole is fixed in the midway of a vertical runner 2 of a casting mold 1 in the mold 1 in such a way that the through-hole parallels with the flow of a molten metal. The molten metal cast through a sprue 8 is cast into a product cavity 5 by contacting at all times with the wall surface of the through-hole provided in the inoculant 7. The shape of the through-hole is made circular to supply efficiently the effective component of the inoculant into the molten metal. The diameter of the through-hole is determined at 0.2 to 0.8 in the ratio of the total sum of the sectional area of the through-hole with respect to the sectional area of the runner 2 to be discharged therein with the inoculant in order to provide a substantial effect of inoculation. The remarkable effect of inoculation to suppress the generation of chill is obtd. as compared with the conventional in-mold inoculant.
摘要翻译：目的：提高接种效果，防止异物流入穿过设在转轮中途的通孔并设置在中心部分的通孔。构成：具有通孔的模内接种剂7固定在模具1中的铸模1的垂直浇道2的中间，使得通孔与熔融金属的流动平行。通过浇口8浇铸的熔融金属通过与接种剂7中设置的通孔的壁表面始终接触而流入产品空腔5.通孔的形状是圆形的，以有效地提供有效的孕育剂的组分进入熔融金属。通孔的直径以0.2至0.8的比例确定，其中通孔的横截面面积相对于流出物2的截面面积的总和与孕育剂一起排出，以便提供接种的实质效果。接种抑制冷冻产生的显着效果是有效的。与传统的模内孕育剂相比。

摘要： PURPOSE:To obtain an excellent inoculating effect and to prevent defect owing to intrusion of foreign matter by melting an inoculant to be added in the stage of casting in a high speed melting furnace different from the same furnace for cast iron, and mixing the same in the form of liquid with the cast iron in the stage of casting the same. CONSTITUTION:A high speed melting furnace 6 for melting an inoculant tilts in synchronization with the tilting of a ladle 4, and the molten inoculant 7 is cast along the flow of the molten metal 3 charged from a ladle 4 into a casting mold 1. The molten inoculant 7 is admitted in the state of being still partly suspended as an uneven concn. in the molten metal into the cavity of the casting mold and therefore a remarkable effect of inoculation is provided in this stage. Since the inoculant 7 is added in the state of liquid, the intrusion of the undissolved material is obviated completely.
摘要翻译：目的：为了获得优异的接种效果，并且通过在不同于铸铁炉的高速熔融炉中熔化在铸造阶段中加入的孕育剂来防止异物侵入引起的缺陷，并将其混合在液体与铸铁在铸造阶段的形式相同。构成：用于熔化接种物的高速熔化炉6与浇包4的倾斜同步地倾斜，并且熔融的孕育剂7沿着从浇包4装入铸模1的熔融金属3的流动被铸造。熔融孕育剂7以部分悬浮状态进入不均匀浓度。在熔融金属进入铸模的腔体中，因此在该阶段提供了显着的接种效果。由于孕育剂7以液体的状态加入，所以不溶物的侵入被完全消除。
