Dry Vibration MIX
This environment friendly dry vibration mix is developed with high purity magnesia bonded by green agent. It performs well on slag erosion and penetration. Featured with excellent thermal shock resistance and spalling resistance, also high strength and volume stability under high temperature, it can meet the needs for the tough working environment. This product is convenient for work and has long life endurance without pollution. The residue is easy to be disintegrated, which can accelerate the recycle of tundish, extend service life of permanent lining, and improve purity of molten steel.
