Hollow core was linked with hydraulic loose-core implement fixed on the moving die.
如果铸造空心铸件时模型上包含伸长杆便于在砂中放置砂芯的空间称为型芯座。
If a hollow casting is to be made the pattern will include extension pieces so that Spaces to accept the sand core are molded into the sand. These additional Spaces in the mold are termed core prints.
最后，本文提出了无芯法连续生产空心钢锭技术需要解决的问题，以及在选定凝固材料和进行锭型设计时的参考意见。
At the end, the paper posted the problems which needed to be solved in non-sleeve technique, and also provided Suggestions in selecting the solidification materials and designing mould.
