摘要
为充分发挥RH-TOP的精炼功能,了解唐山国丰公司第一炼钢RH-TOP的精炼效果,对SPHD冷轧深冲用钢进行了生产试制,成品的化学成分满足标准要求。试生产过程中,整体浇铸过程稳定,可浇性良好,铸坯的氧氮含量控制较低。试生产过程中发现转炉终点、钢包包况、生产沟通等方面存在一定问题,有针对性地提出了改进措施。
To give full play the refining function of RH- TOP and knowthe refining effect of RH- TOP in No. 1 Steelworks of Guofeng,the production trial of SPHD cold- rolling deep drawing steel is done,and the chemical composition of finished product meets the standard. In the trial,the whole casting is steady,castability is good,the oxygen and nitrogen contents in steel is low. Some problems are found in converter end,ladle condition and production communication,and some forwards improving measures proposed.
