简要分析了带钢热轧过程中的有关温度条件，介绍了宝钢２０５０ｍｍ热连轧机通过工艺与设备的改进，降低轧线温降，从而降低板坯出炉温度，以及适当降低粗轧出口温度与精轧终轧温度对热轧带钢表面质量的影响。这种低温轧制技术取得了节能、提高成材率、降低生产成本、提高产品质量的良好效果。 Briefly analyzed the relevant temperature conditions in strip hot rolling process, introduced Baosteel 2050mm hot strip mill through the process and equipment improvements, reduce the temperature drop, thereby reducing the slab tapping temperature, as well as the appropriate reduction of roughing exit temperature and precision Effect of Rolling Finishing Temperature on Surface Quality of Hot Strip. This low-temperature rolling technology has achieved energy saving, improve the rate of finished products, reduce production costs, improve product quality and good results.
