本文研究了武钢转炉补炉后第一炉冶炼2C 船板钢 a_k 值变化的原因,提出了有助于优化热轧船板横向 a_k 值的化学成份和终轧、卷取温度。
In this paper, the reason for the change of a_k value of 2C steel plate of the first furnace smelting after the converter furnace replenishment in WISCO was studied. The chemical composition, finishing rolling and coiling temperature were also proposed to optimize the transverse a_k value of the hot-rolled steel plate.
