建立了环形加热炉管坯加热过程数学模型，使用VB语言编写离线加热程序，并通过“黑匣子”试验验证该程序的准确性；然后，针对某钢厂低碳钢种（Φ=270 mm），加热时间为180 min，采用13因素3水平多目标的正交试验设计方法，对环形加热炉的炉温制度进行分析，并利用综合平衡法对试验结果进行权衡分析；最后，在满足工艺要求的前提下，给出了最佳炉温制度组合，经验证，在此炉温制度下，出炉管坯能满足工艺要求，并降低能耗0.6%左右。

The mathematical model of tube billet heating process in rotary furnace is established. Offline simulation software is developed by VB language, which has been verified exactly by black box test. For low-carbon steel (Φ=270 mm) and 180 min heating time in a steel plant, the method of 13 factors and three levels of multi-objective orthogonal test is adopted and furnace temperature schedule of rotary furnace is optimized. Test results get on tradeoff analysis using consolidated balance method. Under the content of technical requirements, the combination of the best furnace temperature schedule is obtained. It proved that the reheated tube billet can meet the technical requirements and the energy consumption is reduced about 0.6%under this furnace temperature schedule.
