新日铁开发的用于加热中间包内钢液的等离子加热和感应加热两种技术均已成功地用于生产。 等离子加热1987年在广烟制铁所投入工业应用。该方法的原理是利用阴极(等离子枪)和阳极(钢液)间的直流放电提高钢液温度。热量通过直接给热(30％)、直接辐射(18％)和间接辐射(52％)三种方式传入钢液。该装置的关键是等离子枪,有冷阴极和热阴极型两种,等离子电极材料,热阴
Both Nippon Steel’s plasma heating and induction heating technology for heating molten steel in tundish have been successfully used for production. Plasma heating in 1987 in Guangzhou Iron and Steel put into industrial applications. The principle of this method is to use the DC discharge between the cathode (plasma gun) and the anode (molten steel) to increase the temperature of the molten steel. Heat is transferred to the molten steel by direct heating (30%), direct radiation (18%) and indirect radiation (52%). The device is the key to plasma guns, cold cathode and hot cathode two, plasma electrode materials, heat Yin
