Title The design of spectrum acquisition system on Basic Oxygen Furnace
Abstract With advances in optical detection technology, using optical detection technology for the metallurgical industry in the measurement and control has become a new means of metallurgical control. In the metallurgical process, the Basic Oxygen Furnace (BOF) is an important link. BOF endpoint’s precise control has been the world's problems to be solved in the metallurgical industry. BOF steelmaking is the most important steel-making methods in the world. The accurate control of BOF end point has important significance for energy conservation, the reduction the production costs and improvement of the blowing automation’s level. Currently, the traditional BOF endpoint technology is difficult to achieve on controlling the end-point carbon and the temperature accurately. It was found that the furnace mouth flame spectral data implied the information of carbon content and temperature of the furnace steel. Therefore, this thesis emphasizes to propose the construction of spectrum acquisition system on BOF.
