Technics
1. Used the high purified magnesia as bone material,
2. Adding various anchoring agent.
3. Mixing under high temperature.
feature
1. Short sinter time(15-20 minutes);
2. Strong adhesion ability,
3. Improve the ladle service life (extend 15 times after gunning one time)
Application: Gunning the lining of ladle
