摘要
为了避免钼片在轧制过程中出现边部裂纹.对钼片的轧制工艺进行了新的探索.结果表明:钼的轧制开坯温度在1300℃～1400℃为最佳.开坯道次加工率应大于30%,一火多道开坯工艺较一火一道开坯工艺更能避免裂纹的出现.
This paper presents the new study to the rolling technique of molybdenum flats in order to
avoid edge cracks in the volling process. The result shows that the temperature from 1300℃ to 1400℃ is the most suitable for cogging in the rolling of molybdenum. The working rate of every cogging should be more than 30% . The multi -cogging with one heating is more capable to avoid cracks than one cogging with one heating.
