Dry vibrating refractories for work lining and castable for permanent lining of tundish

Dry vibrating refractories for work lining of tundish have two kinds, that is, magnesia and magnesia-calcium, which have long service life, easy disaggregation and no pollution to steel. Constables for permanent lining of tundish take high bauxite and andalusite as raw materials with good thermal shock stability and fine strength at high temperature.
