“田”字型双级双向热底冷盖熔铝炉

介绍一种与地方铝厂技术水平，生产规模，产品结构相适应原新型铝炉。该炉是将中，小型企业无法操作使用的巨型熔铝炉分解成两组双级，双向炉，采用冷炉盖，热底连体结构，与普通单炉相比可减少１６个散热面；采用炉料预热罩强制烟气循环预热炉可节省４０％以上。

Four Chamber Smelting Furnace with Hot Bed and Cold Lid

A new smelting furnace which can fit in with the technology and scale of local aluminium plant is introduced. A large smelting furnace which is not suitable for the middle and small-size enterprises was divided into two group four chamber smelting furnace with hot bed and cold lid. Compairing with the common single ftirnace, it can reduce 16 heat radiation surfaces. Using the preheat bell to keep the exhaust gas circulating, it can save energy more than 40%. The unitary nozzle construCtion can keep the supply of heat constantly and dispel blind angle of airflow, keep temperature equality, increase the smelting spead, cut down smelting time as well. The four chamber furnace is handled easily and has good technologic data. It's the ideal furnace for middle and small-- size aluminium plant.
