依靠技术进步,把建设重点切实转到现有企业的技术改造和改建扩建上来,走内涵为主的扩大再生产的路子,这是加速我国现代化建设的一个重要方面。本着这一精神,本文讨论新钢锰铁高炉的技术改造方向。 一、新钢锰铁高炉现状 新钢建厂20多年来,已逐步发展成为我国的锰铁基地,已有比较雄厚的物质技术基础。它们是: (一)高炉:3×255米~3,1984年入炉焦比为1830公斤/吨。
Relying on technological progress, it is an important aspect of accelerating the modernization drive in our country that we must focus our construction on the technological transformation, rebuilding and expansion of existing enterprises and take the connotation of expanding the path of reproduction. In this spirit, this article discusses the direction of technological transformation of the new steel ferromanganese blast furnace. First, the status of the new steel ferromanganese blast furnace New Steel Construction over 20 years, has gradually developed into China’s ferromanganese base, there is a relatively solid material and technical basis. They are: (a) blast furnace: 3 × 255 m ~ 3, into the coke ratio in 1984 was 1830 kg / ton.
