SiC Graphite Stopper Rod For Steel Continuous Casting Tundish
Description
SiC Graphite Stopper Rod is an essential casting component designed to control molten steel flow from the tundish to the mold.
It has oxidation-resistant glaze coating, excellent erosion resistance, and strong thermal shock resistance.
SiC Graphite Stopper Rod Characteristics
- Oxidation-resistant glaze prevents carbon-bonded material oxidation.
- Body and head materials provide strong thermal shock and erosion resistance.
- Special slag line materials improve anti-erosion properties.
- Can blow Argon into steel channel to prevent inclusions.
