Product Description

Ladle drain sand /Low thermal expansion rate, good thermal conductivity, large density,not easy wetted by molten steel


Product description:


Zhengzhou Xinyu can supply Silica-based and Chrome-based filler according to customer`s requirement. Silica-based filler use quartz sand as raw materials,mixed with lubricant and sintering aid. Chrome-based filler use South-Africa Chrome ore as raw materials,mixed with lubricant,sintering aid deoxidizer and etc features good self-flow rate,normally above 95%.

Category of Refractory Functional :

  • Silica-based
  • Chrome-based


The products series of fillers for ladle tapping hole can be used for kinds of ladle, LF ladle, show the features ofnon-floating,high self-open rate,easy installation and safety.
