20t钢锭的轧制及轧后的冷却过程可建立起二维矩形数学模型,计算这个模型,得出了用热态初轧坯直接再轧制的可行条件,为轧钢厂系统节能提供了依据。
The two-dimensional rectangular mathematical model can be established by the rolling of 20t steel ingot and the cooling process after rolling. Calculating this model, the feasible conditions of direct re-rolling with hot initial billet are obtained, which provide the basis for energy saving of the rolling mill system.
