我国石墨化电炉基本上都采用爱契逊石墨化电炉,从设计上大多仅仅考虑到炉子必须非常牢靠地保证石墨化电炉工艺要求(即使炉芯坯料在终炉时炉温达到2500℃以上),人们担心炉子散热损失大,往往采用厚炉底,厚炉墙(端墙)和厚保温料。这种设计一直延用至今,虽然这种设计从工艺上确保炉芯温度2500℃的保温要求,但却使石墨化电炉工作时电热损失增大,使石墨电极电耗的增大。从实际石墨化电阻炉热平衡测试计算数值中可以看出炉子蓄热损失和保温料蓄热损失所占的比例。如兰州炭素厂α—8#炉,该炉炉体蓄热损失为74.8×10~6KJ,占热支
Most of our graphitized electric furnaces use Aedeschem graphitized electric furnaces. Mostly from the design, only the furnaces must be very reliable to guarantee the technological requirements of the graphitized electric furnaces (even if the furnace core billet reaches a temperature above 2500 ° C in the final furnace) People are worried about the furnace cooling loss, often using thick bottom, thick furnace wall (end wall) and thick insulation material. This design has been extended until now, although this design from the process to ensure that the core temperature of 2500 ℃ insulation requirements, but the work of graphitization electric heat loss increases, the graphite electrode power consumption increases. From the actual graphitization resistance furnace heat balance test calculation value can be seen in the furnace heat storage loss and heat preservation material heat loss proportion. Such as Lanzhou carbon plant α-8 # furnace, the furnace heat storage loss of 74.8 × 10 ~ 6KJ, accounting for hot branch
