Submerged arc furnace for producing macrocrystalline fused magnesite
The invention provides a submerged arc furnace for producing macrocrystalline fused magnesite. The submerged arc furnace comprises a furnace barrel device, a feeding device and a flue gas collecting device, the feeding device and the flue gas collecting device are connected with a furnace cover of the furnace barrel device, and the flue gas collecting device preheats materials in the feeding device by using flue gas. According to the submerged arc furnace, the flue gas of the submerged arc furnace for macrocrystalline fused magnesite is recycled, and raw materials are preheated by utilizing flue gas waste heat; in the production process, natural magnesite powder can be pre-decomposed by high-temperature flue gas, most CO2 gas is released in advance, and the adding proportion is increased; and automatic feeding can be realized through flue gas temperature monitoring.
本发明提供一种生产大结晶电熔镁砂的矿热炉，包括炉筒装置、进料装置和烟气收集装置，所述进料装置和烟气收集装置与炉筒装置的炉盖相连接，所述烟气收集装置利用烟气对进料装置中的物料进行预热。本发明通过大结晶电熔镁砂矿热炉烟气回收，利用烟气余热预热原材料；生产过程中天然菱镁矿粉可以被高温烟气预分解，提前释放大部分CO2气体，提高其添加比例；本发明还能够通过烟气温度监测实现自动加料。
