| 中文摘要: |
| 以 Mn57-2-2-0 . 5 锰黄铜半连续铸造生产实践为例,分析了试制过程中产生裂纹的原因,通过结晶器结构优化、冷却水强度分配及浇注速度调整等措施,解决了该类缺陷。 此工艺措施对同类合金的同类缺陷非常有效,同时对探索复杂黄铜半连续铸造生产有一定借鉴意义。 |
| 英文摘要: |
| By Mn57-2-2-0. 5 Manganese brass semi-continuous casting producting practice as example, the crack reason during trial manufacture is analyzed. Through measures of the crystallizer structure optimization, cooling water intensity distribution and casting speed adjustment this defect is solved. The measures are very effective for similar alloys and similar defects, and have a certain significance for exploring the complex brass semi-continuous casting production. |
