| Abstract: | Based on the high strength steel production practice,according to the production process route of KR-converter-LF-RH-CCM,taking the idea of technology integration and optimization,Jinan Steel built clean steel production process platform and achieved good control effect for the harmful elements and inclusion in the steel. The total sum of the P,S,N,O and H contents was controlled between 104×10-6 and 259×10-6. The P content in the steel was controlled between 67×10-6 and 144×10-6 and the TO] average content was controlled in 20×10-6 about. The control level of inclusion B and D was 1.5 grade below,realizing the stable and mass production of low-alloy and high strength steel,and ensuring the product quality and performance requirements. |
