介绍了年产100万t的某棒材中小型轧钢车间冷床的工艺尺寸计算和冷却能力的校核。对棒材在冷床上的冷却主要考虑热辐射,采用波尔茨曼公式计算棒材冷却所需时间,求出冷床长度,并将该时间与棒材在冷床上实际通过的时间进行比较,校核了冷床长度。
The process dimension calculation and cooling capacity verification of the cold bed of a bar rolling mill with an annual output of 1 million t are introduced. The cooling of the bar in the cooling bed mainly consider the heat radiation, the use of the Boltzmann formula to calculate the time required to cool the bar, calculate the length of the cooling bed, and the time the bar and the actual time on the cooling bed to compare, Check the cooling bed length.
