【摘要】 根据某公司热轧厂铸坯粗轧热过程的工艺条件,建立了铸坯粗轧热过程二维传热数学模型,并利用现场实测数据对所建立的数学模型进行了对比分析计算。模型计算值和实测值的最大相对误差为3.1%,完全满足实际生产过程中计算机控制系统对数学模型计算精度的要求。证明所建模型是正确可靠的。所做工作可以作为计算机在线控制的理论基础。更多还原

【Abstract】 According to the technological conditions of thermal process for rough rolling of continuous casting slab of hot rolling plant,two-dimensional heat transfer mathematical model is established and contrasted with the measured data, the maximum relative error is 3.1% between the calculated value and the measured data,so the mathematical model completely meets the demands of calculated precision,and it is proved that the model is correct and reliable.The work we have done provides theoretical basis for on-line controlling of computer.更多还原
