摘要
板状件具有壁厚较小且均匀的特点，采用湿型铸造工艺配以低温快速浇注，可以成功地生产高锰钢板状件。由于有效地抑制了微观组织的柱状晶生成，提高了铸件强度和抗冲击性能。
reens and molding with fast pouring in low temperature succeeds in production of plank-like parts of high-manganese steel featured by thin and even section.The effective restraint on column crystal increases both strength and impacting value of castings.
