采用热风碱性化铁炉,是用高硫生铁进行转炉炼钢的重要手段,即在化铁炉中进行碱性操作,利用高碱度渣脱硫,以保证钢质量的提高。但是碱性化铁炉的寿命一般较低,甚至影响到车间的连续生产,而化铁炉寿命短的关键是化铁炉过铁道的寿命太短,往往是其他部位还能正常工作时,过铁道就先坏了,因此,要提高碱性化铁炉的寿命,首先必须提高过铁道的寿命。提高过铁道的寿命,一方面要提高制砖质 The use of hot air alkaline iron furnace, is the use of high-sulfur pig iron converter steelmaking an important means that in the iron furnace alkaline operation, the use of high alkalinity slag desulfurization, in order to ensure the improvement of steel quality. However, the life of the basic iron furnace is generally low, and even affect the continuous production workshop, and the key is the short life of the iron furnace over the railway life is too short, often other parts can work normally Therefore, to improve the life of the basic iron furnace, the life of the railway must first be raised. Improve the life of the railway, on the one hand to improve the quality of the system
