（一）前 言 由于LD氧气顶吹转炉的迅速发展,陈旧的铸锭系统成为生产能力进一步提高的薄弱环节;老的钢厂技术改造时,炉前生产能力成倍增加,原有整脱模能力也显不足。因而,如何简化铸锭工序,改善冶炼与铸锭不相适应的被动局面,成了冶金工作者的研究课题。 基于上述原因,近十几年来绝热板浇钢新技术在许多国家得到迅速推广。我国从1974年开始绝热板的试验研究,八年来经许多科研单位、生产厂的科技工作者和工人的共同努力,现在国内已逐步推广。
(A) of the preface Due to the rapid development of LD oxygen top blown converter, the old ingot system has become the weak link in the further increase of production capacity; old steel mills technological transformation, double the production capacity of the front burner, the original full mold release ability Is also insufficient. Therefore, how to simplify the ingot process and improve the passive situation that the smelting and ingot are not suitable has become a research subject of metallurgical workers. Based on the above reasons, the recent more than a decade of new technology for steel plate insulation in many countries have been rapidly promoted. Since 1974, China started the experimental study of thermal insulation panels. Over the past eight years, thanks to the joint efforts of many scientific research units and scientific and technological workers and workers in production plants, it has been gradually promoted in China.
