종일강SPHD심충강생산실제출발，분석료해강충C、O、P、S、N등관건원소적공제요점；전로종점C함량개우0.04％～0.07％적비례체도79.3％，중간포평균C 0.015%；주배O공제재22×10-6좌우，중간포평균P 0.015%，중간포S공제재0.011%좌우，배양N≤30×10-6합격솔위86.6%。
Based on production reality of second steelmaking plant of Rizhao Steel, main control points of C, O, P, S, N and other key elements in SPHD deep drawing steel were analyzed;the ratio of BOF end-point C content ranging from 0.04%to 0.07%reached 79.3%. The main elements of controlling results are as follows:average C in tundish 0.015%;O in billet about 22×10-6, average P in tundish 0.015%, average S in tundish 0.011%, pass rate of billet N≤30×10-6 86.6%.
