对永通铸管公司铁水化验率低的原因进行了分析,并提出了改进措施。利用现场分析与统计分析查找S、Ti 量的分析准确率直接影响化验结果的准确性。针对这两个因素,采取了有效的改进措施。通过在岗位开展劳动竞赛、加强仪器的维护与校验、净化氩气以及重新设计、修改样模、加强工艺纪律检查,杜绝试样夹渣等措施,铁水 S、Ti 量的分析准确率得到提高。
The reason of low rate of hot metal test in Yongtong Pipe Company was analyzed and the improvement measures were put forward. The use of on-site analysis and statistical analysis to find S, Ti, the accuracy of the analysis of a direct impact on the accuracy of laboratory results. In view of these two factors, effective improvement measures have been taken. Through the labor competition in the post, strengthen the instrument maintenance and verification, argon gas purification and redesign, sample modification, to strengthen the process of discipline inspection, to eliminate the sample slag and other measures, molten iron S, Ti analysis of the accuracy rate is improved .
