摘    要：提要用极值法得出了预焙槽阳极碳块最佳高度(H_佳)的数学表达式。H_佳植与电解槽的类型和容量有关.实例计算表明:某厂72kA敞开槽的H_佳值为566mm,128kA密闭槽的为580mm,160kA密闭槽的为603um,均高于原设计值.

Abstract: A formula for calculating the optimal height of prebaked carbon anodes has been proposed with the help of critical value, method. The expression is as follows: H₀=A(a/b)^1/2 +h_r(cm)where: A——anode height coefficient, dependent on the basic design parameter for the prebaked eleetrolytical cell, its value being in the range of 12. 0--14. 0; b----price of the prebaked carbon anode,, (￥)/kg; a——price of the direct current, (￥)/kWh; h_r——height of the remaining anode, cm. The results of H₀ with respect to the practical examples with capacity of 72,128 and 160 kA is 566, 580 and 603 mm respectively, all of them being higher than the original design values.
