Dolomite brick with free lime

Conclusions Technology has been devised for the production of dolomite brick was free lime. To obtain parts, pure dolomite with a high content of free calcium oxide and sufficient free magnesium oxide and a low content of alumina and sesquioxides, the latter in sufficient quantity to ensure sintering, should be used.Anhydrous binder P can be used as the bond since it enables strong green material to be obtained after drying.The green material should be dried in a drier with an extracting fan at 250–300°. The heat transfer agent should not contain water vapor.The parts should be fired at 1600° for 5 hours; the temperature rises to 250° during the first hour.
