It is removed with transverse-moving trolley, then fixed petticoat pipe is hung out, then movable gas hood is placed on converter furnace roof, crane is utilized after inclination
It hangs out, entire replacement process needs 72 hours or more.If movable gas hood is directly dropped in converter converter of verting again to hang out, meeting
It causes all multiple locations of movable gas hood to interfere with fixed petticoat pipe and does not hang not come out.Replacing construction is overhauled to reduce, improves overhaul efficiency,
It needs to be transformed movable gas hood, movable gas hood is dropped in converter converter of verting again and hangs out replacement by realization.
Summary of the invention
The present invention is intended to provide a kind of simple and practical fast changeable turn for overcoming above-mentioned prior art shortcoming
Furnace movable gas hood overcomes movable gas hood to drop in converter interference when converter of verting again is hung out with fixed petticoat pipe, can be effective
It reduces movable gas hood and overhauls replacing construction, improve converter producing efficiency.
The purpose of the invention is achieved by the following technical solution:
Converter movable hood, including water-inlet header, water inlet pipe, out water manifold, outlet pipe, water screen tube, lifting device, movable cigarette
Cover is that tray type structure is arranged in above converter mouth；Water screen tube using close arranging pipe by water inlet pipe and outlet pipe respectively with water inlet
Header is connected with water manifold out；Water-inlet header and water manifold symmetric design out, the extreme higher position of water-inlet header and out water manifold is not
Higher than the upper surface of refractory material on movable gas hood；The extreme higher position of lifting device not higher than on movable gas hood refractory material it is upper
Surface.
Totally 4 sets of the lifting device, it is evenly arranged in the surrounding of movable gas hood.
Movable gas hood uses low force circulating water, and water inlet distribution requires uniformly, and recirculated water cannot vaporize.
Activity cigarette impinges upon down position and covers in converter when converter is normally made steel, and has fixed petticoat pipe above movable gas hood, Gu
Determine petticoat pipe to connect with the removable flue of top again.The flue gas that converter generates passes through movable gas hood, fixed petticoat pipe and removable cigarette
Road discharge and processing.When converter needs to feed and when blowing, movable gas hood is promoted to upper, converter by tilting equipment inclination in fact
Now charging and blowing.The purpose designed in this way is to realize that movable gas hood can not remove in not traversing removable flue and fixed cigarette
Movable gas hood is directly replaced under conditions of cover.
Beneficial effects of the present invention: when movable gas hood drops to bottom and falls in converter, movable cigarette during converter tilting
