连铸板坯质量 第三讲 板坯连铸拉速变化对铸坯质量的影响

The quality of C. C. slabsLesson Three Effect of speed changes on slab quality in CC

拉速变化与辊子弯曲、扇形体张开力、铸坯鼓肚、冶金长度、结晶器热面温度等对板坯质量的不利影响进行讨论,提出为解决这些问题应采取的措施。

This lecture discusses the effects of casting speed changes on roll bending, bulging, segment opening force, metallurgical length and hot face temperature of the monld as well as the detrimental effects on slabs.The measures are also put forward to solve the problems.
