提高LF—连铸钢液温度稳定性的分析与实践

On Raising Stability of Molten Steel Temperature in LF-Continuous Casting Process

对影响珠钢150 t LF和中间包钢液温降的因素进行了分析,发现工艺制度的不完善导致了精炼上台温度控制的不稳定,出现了中间包钢液过热度偏高、钢液温降大等现象。通过优化相关工艺制度,引入实时监控系统,加强管理,可保证连铸钢液温度的稳定性、显著降低漏钢率。

The factors affecting the temperature drop of molten steel in 150 t ladle furnace and tundish in Zhujiang Steel was investigated. It is found that because of imperfect technology regulation, the temperature of end-point control in ladle furnace is unstable, the superheat in tundish is on the high side and the temperature drop is larger. By optimizing the technological regulation, importing real-time monitoring, strengthening the management , the molten steel temperature stability can be assured and the breakout rate can be reduced greatly.
