Types Of Refractories

Dolomite Refractory: Dolomite bricks are made up of MgO 25-45%, CaO 35-65%, and other materials. They have high refractoriness, Thermal stability at high temperature and slag resistance. They are more porous, more shrinkage softness and less strong. They can be used up to 2300 o C without load and up to 1650 o C with the load.
