【摘要】 为了适应计算机在线控制的要求,利用“改进型田中功法”将“无限长二维矩型数学模型”转化为“无限长圆筒一维数学模型”,建立了“钢锭系统热送热装热过程一维在线控制数学模型”。结果表明:对宝钢目前的钢锭热送热装系统而言,一维和二维数学模型计算结果的最大绝对误差为 27℃、最大相对误差为 2.30%,完全能够满足计算机在线控制系统对数学模型计算精度和速度的要求。所做工作对即将投运的“宝钢钢锭系统热送热装热过程计算机优化控制系统”具有重要的指导意义。更多还原

【Abstract】 For the requirements of on-line computer control, The one-dimensional mathematical model for the hot transferring and chargingprocess of ingot system has been established by the“Rreformed Tanaka Kou’s Method”that translates the two-dimensional mathematicalmodel of the infinite length type of rectangle into the one-dimensional mathematical model of the infinite length type of cylinder. The resultshave showed that the maximal absolute error of calculated results between the one-dimensional mathematical model and two-dimensionalmathematical model was 27℃ and the maximal relative error of calculated results was 2.30%, so the one-dimensional mathematical modelmeets completely the demands of calculated precision and speed for the on-line control system.更多还原
