摘要
本文从铸锭的表面质量;铸锭表层的结晶组织及力学性能;铸锭边部的某些合金组元含量高时;易富集气体缺陷等四个方面阐述了普通模铸造一次冷却结晶区的铸锭质量及影响。
The text introduce quantity and influences in the casting lies the first area of cooling and crystallize in common mold from four aspects. For example： the surface quantity, crystallize organizes and having high alloy elements, gather air easyly of the side department in the casting and craft process.
