Product Description:
Product Brief Introduction:
Stopper head brick is located at the bottom of the stopper rod and closely matched with the nozzle brick,To control the casting switch. The stopper brick is the core component of the stopper rod system.
When the casting is not poured, the nozzle brick is in line contact with the stopper brick to ensure that no leakage of molten steel.
Features:
1. High fire resistance.
2. Good thermal shock risistance.
3. Good wear resistance and crack resistance.
4. Good corrosion resistance.
5. Won't pollute the molten steel.
6. Regular shape,precise size and smooth runner.
