Because the blast and oxygen amount of the oxygen-enriched top-blown furnace is large, the stirring of a molten pool is strong, the splashing of a melt is serious, the scouring and viscosity of high-temperature dust and smoke are large, the common problem in the use process is that a flue cone diameter-changing position spliced steel water jacket is easy to burn through, local is easy to nodulation, the service life is short, and the normal operation of complete equipment is influenced.
The flue has short service life mainly because of unreasonable design, poor cooling effect of the spliced steel water jacket and uneven heat load distribution, the traditional flue adopts steel plate water jacket splicing, slag hanging nails are welded on the inner side of the flue, and then a refractory structure is rammed. The steel water jacket spliced at the reducing position of the flue cone is easy to form cooling dead angles, a cooling channel which is limited in processing and can not be uniformly distributed cannot be designed, the local overheating is easy, the timely cooling of the heat of the flue gas cannot be guaranteed, the flue and particulate matters are caused to scour and resist the peeling off of materials, the vortex effect furnace shell at the reducing position of the flue is burnt out, the collapse phenomenon occurs, and the potential safety hazard in use exists.
Aiming at the problems, the technical problem that the flue of the oxygen-enriched top-blown furnace is easy to burn through is solved by continuously exploring, researching and developing the special-shaped copper water jacket of the flue gas collecting flue with the efficient cooling effect.
