Blast furnace is a closed high temperature and pressure smelting vessel, air supply device by the tuyere equipment that is mounted on furnace shell to
Hot wind is blasted in furnace.Existing tuyere case is divided into tuyere small sleeve, tuyere medium sleeve and tuyere big sleeve, and wherein one end of tuyere medium sleeve is logical
It crosses tapered surface and tuyere small sleeve is tightly connected, the other end is tightly connected by tapered surface and tuyere big sleeve, tuyere small sleeve and air port
Middle set be copper metal constitute, tuyere big sleeve be iron quality metal material constitute, the higher cost of copper so that tuyere case at
This is higher, and respective inflow and outflow system is respectively set in tuyere small sleeve, tuyere medium sleeve, tuyere big sleeve, for tuyere case is cold
But, due in tuyere case tuyere small sleeve and tuyere medium sleeve be set in furnace, so wherein be heated most serious face be that air port is small
Wind taper pipe portion and the barrel-shaped face of outer face cone are crossed among set and front end portion, the damage at these positions are to cause blast furnace staying
The main reason for maintenance, and as tuyere case uses the extension of time, it be easy to cause in tuyere small sleeve and tuyere medium sleeve, air port
Set at the mating surface of tuyere big sleeve because mating surface deform caused by leak out, the gas leak in furnace is also easy to cause personal injury thing
Therefore tuyere medium sleeve uses long, because copper material intensity is low, long-term work at higher temperatures, be easy to cause deformation, causes air port small
Easily assembling, mating face seal be not tight for set.
