Effect of Fluctuation of Casting Rate on Internal Quality of 250mm x 280mm Bloom of Bearing Steel GCr15

The production process of tested bearing steel GCrl5 is 100t BOF- LF-RH-250mm x280mm bloom casting-φ70mm bar rolling. The effect of bloom casting rate 0.52〜0.58 m/min of bearing steel GCrl5 with casting parameters of mold cooling water rate 2530 L/min, liquid superheating extent 33~37℃ , secondary c...
