Study and Application on Magnesia-Forsterite Dry Vibration Material for Tundish

摘要

The paper studies the effects of the addition of forsterite ore and light burnt forsterite as aggregate on the physical properties and slag resistance in resin bonded magnesia-forsterite dry vibration material. The results show that the physical properties and slag resistance have no obvious changes between the two materials. The application in steel mill shows that: the slag resistance decreased a little due to the sintering of the dry vibration material, which is mainly attributed to the formation of monticellite, spinel and glass phase by dissolution and chemical reaction between tundish slag and the matrix of the dry vibration material.
