| Abstract: | The Φ80 mm rolled product of high quality gear steel 20MnCr5H-l for car (/% ： 0.17-0.22C, ≤ 0.12Si, 1.0~1.5Mn, ≤ 0.035P, 0.015-0.035S, 0.8-1.3Cr, ≤ 0.0020O, 0.015-0.045A1) has been developed by 40 t EAF- LF- VD- 3.7 t ingot casting-rolling process. With the process measures including controlling EAF end P] W 0. 015% , LF refining slag basicity ≥ 2.5 and adjusting content of elements in steel, VD treating and feeding sulphur wire, the analysis of 5 heats steel 20MnCr5H-l is (/%：) 0.16-0.20C, 0.05-0.12Si, 1.20-1.30Mn, 0.009-0. 025P, 0.020-0.035S, 1.00-1.10Cr, 0.0008-0.0015O , 0.015-0.040Al, hardenability band width △HRC 4, and each index all meets the requirement. |
