摘要: 通过0Cr18Ni9不锈钢180 mm×1 238 mm连铸板坯侧凹浇铸试验,得出连铸板坯侧凹浇铸对热轧钢卷侧翻(两边粗糙带)和结晶器寿命的影响结果表明,当连铸板坯边部侧凹3~4 mm浇铸时,钢卷侧翻平均宽度由原先的11.2 mm降低至9.3 mm,提高了钢卷的利用率,同时对结晶器的损害很小。

Abstract: Effect of reentrant casting of slab on the side reversal ( both side roughness band) of hot rolled coil and the mold life is obtained by test of reentrant casting of 180 mm X 1 238 mm 0Cr18Ni9 stainless steel slab. Results show that as the cast slab side reentrant value is 3 ~4 mm, the average width of side reversal of coil decreases to 9. 3 mm from original 11.2 mm, it is available to increase the utilization rate of coil, while the damage of mold is minor.
