摘要
针对包钢RH干式真空泵系统装备条件,根据干式真空泵系统工作原理与特点,优化并解决了干式真空泵系统运行中存在的问题。干式真空泵技术与装备应用于RH炉工艺,提升了RH炉抽气能力、脱碳能力、脱氢能力以及钢水循环速率。真空处理15 min后钢水中的[C]质量分数达到10×10-6以下,真空处理20 min后钢水中的[H]质量分数达到1×10-6以下。干式真空泵系统的运行稳定、节能环保,极大的降低RH工艺成产成本。
The problems existing in the operation of the dry vacuum pump system were optimized and solved according to the equipment conditions of the RH dry vacuum pump system in Baotou Steel.The air evacuation capability,decarbonization,dehydrogenation and liquid steel cyclical speed rate were improved,after dry vacuum pump system technology and equipment applied in RH furnace process.The mass fraction of carbon in molten steel was less than 10×10-6 after vacuum treatment for 15 min,and the mass fraction of hydrogen in molten steel was less than 1×10-6 after vacuum treatment for 20 min.The stable operation of the dry vacuum pump system,energy saving and environmental protection greatly reduced the production cost of RH process.
