中温盐浴炉快速启动法是近几年发展起来的,方法较多,有“自激”式、“它激”式、“盐渣法”等。方法尽管不同,但是当达到热平衡后,它们所消耗的能量都应该是一样的。由于快速启动法的出现,传统的副阻启动法有被淘汰或否定的可能。我们认为传统的副组启动法仍是有效的启动方法,有潜力可挖,也可实现快速启动。一、副阻设计以75kW埋入式中温盐浴炉为例,炉膛尺寸350×350×600mm,三相四极制。原用副阻螺旋尺寸φ120 In warm salt bath furnace rapid start method is developed in recent years, many ways, there are “self-excited” type, “it excited” type, “salt slag law” and so on. The methods, though different, should consume the same amount of energy when the heat balance is reached. Due to the rapid start-up method, the traditional deputy resistance start-up method may be eliminated or negated. We think the traditional sub-group start-up method is still an effective start-up method that has the potential to be exploited and can be quickly started. First, the deputy resistance design to 75kW buried temperature salt bath furnace, for example, the furnace size 350 × 350 × 600mm, three-phase four-pole system. The original deputy blocking screw size φ120
