摘要
金属表面电渣加热是一种新的金属表面加热技术。在电渣主动和被动加热试验的基础上,对金属表面电渣加热过程中的热电场传输现象进行了模拟研究。初步试验和模拟结果表明,在金属表面电渣主动加热过程中,电极和被加热金属之间的高密度电流形成的高热源区使金属表面迅速升温。这种加热技术具有加热速度快、节能等特点,从而为金属材料的复合和对金属进行表面处理时的加热方法开辟了一条新的途径。
Electro-slag metal surface heating is a new technology of metal surface heating skills. Based on heating by electro-slag negatively and actively. The thermal-electric field＇s transmission phenomenon in the electro-slag heating process is simulated. The results show that the high heat source region formed by high dense current between the electrode and material surface made the metal surface be heated up soon. This heating method has many advantages of heating-up quickly, energy conservation and so on. So it can inaugurate a new method on metal surface heating when compounding metals or taking heat-treatment.
