现代双床平炉冶炼的特点是具有同转炉强化冶炼相匹敌的高速加热和钢水的高速脱碳。获取钢水温度和碳含量讯息的旧方法难于有效地控制冶炼,经常使钢水加热和脱碳失去协调,以致影响生产。没有关于钢水氧含量的连续的或准确的讯息是钢水过氧化和成品钢锭质量下降的一个原因。因而在强化熔池吹炼条件下,获取熔池中钢水温度、碳含量和氧的连续讯息有着重要意义。捷列波耶夫斯克冶金工厂同莫斯科钢和合金学院以及东方耐火材料学院配合,研究决定
Modern double-bed hearth smelting is characterized by the same with the converter to strengthen the smelting of high-speed heating and molten steel high-speed decarburization. The old methods for obtaining information on the temperature and the carbon content of molten steel are difficult to effectively control the smelting and often make the heating and decarburization of molten steel uncoordinated so as to affect the production. There is no continuous or accurate message about the oxygen content of the molten steel as a result of the overheating of the molten steel and the deterioration of the quality of the finished steel ingot. Therefore, it is of great significance to obtain the continuous message of molten steel temperature, carbon content and oxygen in the molten pool under the condition of enhanced molten pool blowing. Te Lieboyevsk metallurgical plant with the Moscow Institute of steel and alloy and Oriental Refractories Institute, the study decided
