在几个连铸用的中间罐上成功地安装了等离子加热设备,使钢水温度控制得到改善。已经达到了降低冶炼成本和改善钢质稳定性的目的。在中间罐中,用等离子加热钢水的基本目的是使熔炼温度保持在液相线以上约10±5K的范围内。其优点是: ①浇铸的铸坯具有等轴结晶结构;
Plasma heating equipment was successfully installed on several continuous casting cans to improve control of molten steel temperature. Has achieved the purpose of reducing smelting costs and improving the stability of steel. In the intermediate tank, the basic purpose of heating the molten steel with plasma is to maintain the melting temperature in the range of about 10 ± 5K above the liquidus. Its advantages are: ① cast slab has an equiaxed crystal structure;
