Study and Development on New Technologies for Modern Blast Furnace
In recent years great progress is made in technical equipment of large sized blast furnace in China.A series of new process,technologies and equipments,integrated and developed independently,are applied on modern large sized blast furnaces and have been proved to be highly effective.After more than 20 years’ development and innovation of the bell-less top equipment designed and developed,it has reached the advanced level in the world in terms of equipment reliability and service life; fully dry type impulse bag filter cleaning technology of BF gas,which is also developed,has reached technical breakthroughs in terms of optimized system design,gas temperature control,pneumatic transportation of collected dust fines; the integrated innovative high efficiency long campaign life high blast temperature technology,through applying high temperature preheating technology of combustion air,improving heat transfer efficiency and optimizing structure of the hot blast stove,enables the blast temperature to reach 1300℃ with BF gas as fuel.
