摘要
带钢酸洗循环系统是冷轧厂酸洗车间的核心,直接影响带钢的品质。酸洗系统是用化学方法去除带钢表面氧化物的工艺过程。介绍带钢酸洗系统组成、设计理念及工艺流程。阐述了带钢酸洗时间选择时需要考虑的因素,分析了氧化铁皮、紊流强度、酸液温度及浓度对酸洗时间的影响规律。提出带钢加热功率计算方法,分析了带钢厚度及速度对温度计算的影响。以节能环保为出发点,讨论了新酸消耗量和风机设计时需要考虑的因素,并提出相应计算方法。设计理念及方法用于国内多条酸洗机组,应用效果良好。
Strip pickling circulation system is the core of the acid abrasion workshop,directly affecting the quality of strip steel.Pickling system is the craft process to use chemical method to remove the surface oxide of the strip.The design concept and process flow of strip pickling line have been introduced.Influent factors of pickling time have been discussed,and also the effect of scale,turbulent strength,temperature.Concentration on pickling time has been analyzed.The heating power,hydrochloric acid consumption,hydrochloric acid mist and fan have been calculated.The design method has been used in pickling lines,and the purpose of energy conservation and environmental protection have achieved.
