摘要
随着“双碳”战略的实施,钢铁行业对中厚板热轧轧制所需的电耗优化提出了更高的要求。为了实现中厚板热轧轧制电耗的量化计算与预测,通过构建电耗理论计算模型,开发了一套中厚板热轧轧制电耗计算软件。该软件可根据生产钢种及产品目标需求,制定轧制规程,并计算出各道次轧制生产所耗电能及单块板坯的吨钢电耗,为钢企量化中厚板轧制过程的电耗,优化轧制工艺提供数据支撑。通过与钢厂生产数据对比,在厚度命中率达到99%的情况下,该软件计算结果与实际生产数据基本保持一致,粗轧各道次电耗偏差保持在10%以内,粗轧吨钢电耗偏差为-3.12%~3.86%,能够准确反映钢板在轧制过程中的电耗。经过验证,该软件可以为开发新钢种与新工艺、钢厂排产、轧机主电机选型提供数据支撑,有助于钢企进一步实现节能减排,为钢企创造经济效益。
With the implementation of the"dual carbon"strategy,the steel industry has put forward higher requirements for optimizing the electricity consumption required for hot rolling of medium and heavy plates.Aiming to achieve quantitative calculation and prediction of electricity consumption during hot rolling of medium and heavy plates,a theoretical electricity consumption calculation model was constructed and a set of electricity consumption calculation software for hot rolling of medium and heavy plates was developed.This software can formulate the rolling schedule according to the produced steel and target demand and accurately calculate the electricity consumption for each pass of rolling manufacturing and the electricity consumption per ton of steel of a single slab,which can provide data support for steel enterprises to quantify the electricity consumption in the medium and heavy plate rolling process and optimize the rolling process.By comparing with the manufacturing data of the steel mill,the calculation results of the software are basically consistent with the actual situation when the thickness hit rate is almost 99%,the deviation of electricity consumption in each pass of roughing rolling is kept within 10%,and the deviation of electricity consumption per ton of steel inrouging rolling is-3.12%-3.86%,which can accurately reflect the electricity consumption of the plate in the rolling process.After verification,this software can provide data support for developing new steel grade and new processes,scheduling manufacturing,selecting the main motor of the rolling mill,and so on,which helps steel enterprises further achieve energy conservation and emission reduction,and create economic benefits for them.
