沟槽感应电炉的经济技术指标同炉中热质量迁移过程的强弱有关。在沟槽感应电炉的熔池内热量迁移是通过热传导,熔体内电磁力引起的自由的和强制性对流等方式进行的。正如计算表明,在总的热传递中热传导占一小部分,所以,可以认为沟槽感应电炉内的热量传递主要通过热对流和电力引起的熔体质量迁移来实现的。熔化铝合金用沟槽感应电炉的热质量交 Trench induction furnace economic and technical indicators with the heat transfer process of the quality of the furnace. The heat transfer in the weld pool of a groove induction furnace is carried out by means of heat conduction, free and forced convection caused by the electromagnetic force in the melt, and the like. As the calculations show that heat conduction accounts for a small fraction of the total heat transfer, it is believed that the heat transfer within the trench induction furnace is primarily achieved by thermal convection and power-induced melt mass migration.
