摘要
针对热轧带钢因卷取后钢卷内外圈与芯部的冷却速度不同,导致带钢成品头尾强度高、塑性低的问题,提出了卷取温度凹型控制模式。对不同钢种的带钢采用凹型冷却控制后,头、中、尾力学性能的分析和对比表明,凹型冷却可降低带钢头尾性能偏差,提高热轧带钢性能的通卷稳定性。
U-shaped control model for coiling temperature was put forward to improve the high strength and low plasticity of head and tail of hot rolled strip. The properties contrast of strips by U- shaped model and common model were described, and the good effects of U-shaped control moolel were very obvious.
