Abstract:

This paper studies on the relationship between ladle filler sand and the ladle self-starting pouring.Deeply analyzes from quality,property,adding status of ladle filler sand,and operating status of ladle.The analysis result shows the ratio of ladle self-starting pouring relates to the quality,particle shape & size,thermal conductivity,coefficient of thermal expansion,molten steel penetration resistance of ladle filler sand, status and operation cycling time of ladle,stirred mode of molten steel.We need to choose different type of ladle filler sand based on different ladle application environment.
