步进式炉 meaning in English

walking beam furnace
walking beam type furnace

Through the analysis of heat - transfer process of the slab in reheating furnace , the numerical simulation of the temperature within the slab was carried out with the finite difference method , and an optimized mathematical model for heating - up process curve in a reheating furnace was given by using the flexible tolerance optimization method
摘要通过对钢坯在步进式炉内传热过程的分析，采用有限差分方法对钢坯内温度进行数值模拟，用可变容差优化方法建立了钢坯最优加热数学模型。
