Calcined Dolomite Digitalfire

Notes. Dead-burned dolomite is produced when dolomite is calcined at very high temperatures. It is used both as a refractory product in granular form to repair linings and for making the bricks used in the refractory linings of casting ladles and cement kilns. This refractory work well for ladles because it creates MgO in solution in the slag, which provides an buffering because MgO particles
