Description
Technical field
The present invention relates to a kind of side-blown furnace body uptake flues, and side-blown furnace body uptake flue is used for more particularly, to one kind
Water tank type expansion joint.
Background technology
Side-blown converter smelting process is the advanced smelting process for just innovating appearance in recent years.Since floss hole flue-gas temperature is whole
A highest place of side-blown furnace temperature, at the same be again with boiler flue junction, be the scheme considered first with expansion joint,
Used side-blown 1 structure of furnace body floss hole expansion joint of my company as shown in Figure 1, above inboard wall of burner hearth brick masonary 2,
In the case of the 2 not avalanche of inboard wall of burner hearth brick masonary, installation site does not have defect, due to my company's side-blown converter cylinder body area compared with
Greatly, thus this brick construction can not stable for extended periods of time, partial collapse is occurred as soon as after blow-on some months, in brick body avalanche
Afterwards, expansion joint bottom is completely exposed under the flue gas with 1200 ° of highest flue-gas temperature, since expansion joint high temperature resistance itself is owed
It is good, as soon as cause its service life and our factory side-blown converter time blowing-in operation time phase difference too far, often blow-on expansion joint some months
It is burned out；Expansion joint is not easy to replace under the condition of production, leads between floss hole and boiler water tank wall that gap is excessive, and there are heat
The security risk that gas radiation or spilling are hurted sb.'s feelings.
102052540 A of CN disclose a kind of water-cooled nonmetal expansion joint, including water-cooling wall, upper metal framework, lower gold
