中间包包盖优化改造技术研究

Research on optimization technology of tundish cover

连铸智能制造要求减薄中间包包盖厚度和增加烘烤孔。为了解决由此引起的包盖钢结构整体强度降低、高温变形量增大、保温性能变差等问题,对包盖钢结构进行了优化改型设计。经过现场实施验证,包盖使用寿命由42天提高到85天,包盖表面温度大约降低了180℃。

Continuous casting intelligent manufacturing requires thinning the thickness of the tundish cover and increasing the baking hole. In order to solve the problems such as the overall strength of the steel structure,high temperature deformation and poor heat insulation performance,the modification design of the steel structure for tundish cover was optimized. After the on-site verification,the service life of the cover is increased from 42 days to 85 days,and the surface temperature of the cover is reduced by about 180 ℃ .
