应用IE技术提高转炉炼钢产量和连铸比

Application of IE Technology to Improve Productivity and Continuous Casting Ratio

提高连铸比是优化钢铁企业结构的关键环节

Improvement in Concasting ratio ── key to optimization of structure of steel enterprise

2004年度轴承钢连铸比超过40%。

In 2004 the continuous casting ratio of bearing steel has exceeded 40 % .

抓住机遇大力提高连铸比推动钢铁工业发展

Seize opportunity , to enhance CC ratio promptly and promote development of iron steel industry

此外，随着冶金技术的进步，连铸比增加，各种炉外精炼技术被广泛地应用。

In addition , with the progress of metallurgical technology and the increases of continuous casting capabilities , refining technology of external furnace is applied widely .

该系统配置合理、可靠性高，投产半年连铸比即达到92%以上。

The system is reasonable of configuration and high reliability . The ratio of continuous casting comes up over 92 % in half a year since the system went into operation .

高硫45钢的连铸坯脆性转变温度区间为1100~1000℃，而连铸坯纵向比横向的高温塑性好，高温强度相当。

The ductile-brittle transition temperature zone of high sulphur steel is 1100 ~ 1000 ℃, and hot ductility in longitudinal direction is better than that in transverse direction .
