一、前言绝热板的研制和推广使用是冶金工业的一项重大改革,也是氧气炼钢日益发展的需要。采用上小下大沸腾钢钢锭模衬挂绝热板,代替传统的保温帽浇注镇静钢,可以简化工艺,挖掘炉后潜力,提高整模生产能力,以适应氧气炼钢产量增长的需要。此外,并能节省耐火材料和减轻劳动强度。更为突出的是可以大幅度降低切头率,提高钢材收得率。总之,是多、快、好、省地发展炼钢事业的一项十分有效的措施。 First, the preface The development and promotion of insulation panels is a major reform of the metallurgical industry, but also the growing oxygen needs of steel. Adopting the upper and lower large boiling steel ingot mold lining insulation board, instead of the traditional insulation cap pouring the killed steel, the process can be simplified, the potential of the furnace can be tapped and the overall mold production capacity can be increased to meet the requirement of oxygen steelmaking output growth. In addition, it can save refractory materials and reduce labor intensity. More prominent is that you can significantly reduce the rate of cut, improve the yield of steel. In short, it is a very effective measure to develop the steelmaking industry in a fast, easy and efficient manner.
