重钢2500m^3高炉控制产能生产实践

PRODUCTION PRACTICE TO CONTROL OUTPUT CAPACITY IN 2 500 m^3 BLAST FURNACE OF CHONG STEEL

重钢于2015年10月中旬2座2 500 m^3高炉开始控制产能,单座高炉日产量由5 500 t降低到到4 000~4 500 t。2016年1月底又进一步限产,日产量降低到3 000~3 300 t。对1#、3#高炉2次控制产能情况进行了分析,高炉控制产能时,在外部原燃料质量稳定、内部调整合理、设备维护到位等的基础上,可以维持炉况的长期稳定顺行,并且能够获得较好的技术经济指标。

Two 2 500 m^3 blast furnace of Chong Steel began to control output capacity in the middle ten days of Oct,2015,the daily output per blast furnace reduced from 5 500 to 4 000 ~ 4 500 tons. The production was further limited in the end of Jan,2016,the daily output to 3 000 ~ 3 300 tons. The situation of output control of the two furnaces is analyzed： under the conditions： quality of raw and fuel materials steady,internal adjust reasonable,equipments maintenance good,the furnaces condition can be kept stabilized for a long period,and the better technical and economic indexes can be got.
