基于传热反问题的钢包热状态跟踪模拟
Tracking simulation of ladle thermal state based on inverse heat conduction problem
摘要
Abstract
Temperature control is the key to realize modernized continuous-steelmaking. The temperature loss of molten steel in the ladle turnover process is greatly influenced by ladle thermal state , so the ladle thermal state is significant especially in the endpoint of ladle preheating. But the traditional measurement method and numer-ical simulation can′t realize real-time non-contact temperature measuring of ladle lining inside because of the high ladle lining temperature, complex production site layout and short service life of electronic component. To address the problem, finite difference method was used to solve the ladle lining temperature field and fluent was used to simulate flame temperature field, with the help of established mathematical ladle one-dimensional heat transfer model and adopted inverse heat conduction problem,mathematic inversion method was used to calculate the temperature field of ladle lining inside and implement the visual monitor of 210 t ladle thermal state during the preheating procedure by means of computer language, which contained in the real-time monitoring software compiled by c#, provides a feasible new method to managing ladle and making reasonable preheating rules.关键词
