摘　　要：采用有限容积法(FVM),针对某中型厂步进梁式加热炉建立了钢坯加热过程的数学模型。通过编程模拟了板坯内部的温度场,并与拖偶实验数据进行对比,验证了模型计算结果的可靠性。重点对该厂所生产的轴承钢和T系列管坯钢等合金钢在现有加热制度下的加热过程进行模拟,找到了加热制度制定的不足,并且根据各钢种物性参数的不同,优化制定了加热制度,对实际生产起到了很好的指导作用且达到了节能的目的。模拟结果显示,GCr15采用优化后的加热制度节能量在10%以上。Based on a walking beam reheating furnace of a section steel factory,the mathematical model of slab is established by means of finite volume method.The temperature inside the billet is imitated by programming and compared to the experimental data of black box testing,which thus proves the accountability of calculating results of the module.The heating simulation under the present heating system,with its focus on the alloy steel such as the bearing steel and T series pipe steel billet produced in the factory,helps to locate the shortcomings of heating system.And hence,the original heating institution is optimized,updated and thus regulated according to the differences among various physical properties,which better guides the actual practice of production and ultimately leads to energy-saving.Simulation results indicate that the quantity of energy of GCr15＇s heating treatment will be saved more than 10% by using the optimized heating institution.
