Properties Of Refractory Materials Mecholic
The refractory walls of furnace and kilns attacked by the shock effect of gases and high-velocity abrasive raw solids flow over them. Therefore the refractory must have good wear resistance. Thermal properties 1. Melting point It should have very high melting point. 2. Thermal expansion A batch of raw material may be comprised between 20 and 50 kg. In the case of a melter showing a production rate of approx. 70000 kg/day the batch loading frequency may vary between 20 and 50 kg/min. It is preferred however to feed the raw material substantially continuously or in a manner close to being continuous.
