Description
Technical field
The utility model relates to a kind of converter evaporation cooling air flue feeding chute water jacket, specifically, relates to a kind of metallurgy industry, is arranged on converter evaporation cooling air flue fire door section both sides, is used to the water jacket that adds removal phosphorus, sulphur raw material in converter steelmaking process.
Technical background
In converter steelmaking process, various bulk materials are joined converter from high hopper, need to perforate on the flue above converter, insert feeding chute water jacket, material enters in converter by feeding chute water jacket, and therefore feeding chute water jacket should be wear-resisting high temperature resistant again.The feeding chute water jacket of domestic common design at present has two kinds: a kind of for Inlet and outlet water header adds middle not isometric solid matter straight pipe form feeding chute water jacket, its inwall welds wear rib or adds cast iron wear-resistant trough.This kind of form is because solid matter straight pipe is not isometric, each water pipe water resistance is widely different, each arm flow velocity difference making, inhomogeneous cooling, cause between each arm and produce weld stress, repeatedly between smelting condition lower branch line weld stress produce frequent fluctuation, be so easy to for a long time straight pipe drawing crack to leak, even produce pipe explosion accident.Lower collecting box is positioned at feeding chute bottom simultaneously, and diameter is larger, has obvious projection compared with close arranging pipe, in the time having the raw material of certain degree of hardness to pass through herein with higher speed, causes this position serious wear, so must occur for a long time drainage.Another kind is jacketed type feeding chute water jacket, and its main body forms airtight chuck by two different cylinders of diameter, and top is made up of water inlet pipe, water-inlet header, water distribution pipe, rising pipe.Water coolant enters water-inlet header from water-in, by the water distribution pipe that is evenly distributed on water-inlet header bottom, water coolant is evenly injected to airtight chuck bottom, water coolant is upwards flowed by airtight chuck bottom, flow out from the rising pipe at airtight chuck top, complete cooling to whole closed water-cooled chuck, inner barrel inwall is welded with wear-resisting band steel as wearing layer.This kind of structure overcome the drawback of the first structure formation, but the inside and outside cylinder of airtight chuck need to splice and be welded, and as bad in weldquality, when under the sweep of gases at 1650 ℃, the inner barrel cycle expands with heat and contract with cold, and weld seam very easily ftractures, and leaks.In the time being full of water in water-cooling jacket, integral device weight is large, very uneconomical.Wearing layer adopts band steel, very easily occurs perk when blanking, produces the phenomenon that gets stuck, and causes water jacket wearing and tearing to leak.All there is the drawback such as leak, work-ing life is short in the structure of these two kinds of feeding chute water jackets in sum.

Described bilayer sleeve all adopts weldless steel tube.
The inner sleeve water inlet of described bilayer sleeve is provided with laval nozzle.
The inner wearing layer of described feeding chute water jacket.
Described water-inlet header is connected with water distribution header by distribution piping.
Described go out water manifold by manifold trunk with collect header and be connected.
Following advantages that the utility model has:
(1) increased water distribution header, distribution piping, manifold trunk, collected header, the water coolant distributed uniform making.
(2) water-inlet header, go out water manifold all on feeding chute water jacket top, eliminated the projection between water-inlet header and close arranging pipe, solved the wearing and tearing hidden danger of feeding chute water jacket bottom.
(3) bilayer sleeve adopts tube-to-tube construction, is heated evenly, and thermal expansivity is good, has solved weld stress frequent fluctuation, draws the problem of bad close arranging pipe.
(4) adopt pump circulation water cooling, the water inlet of every road close arranging pipe increases laval nozzle, guarantees water coolant uniformly distributing, has avoided close arranging pipe local superheating, and booster fault occurs.
(5) the inner wearing layer of feeding chute water jacket adopts water flowing weldprocedure, and build-up wear-resistant piece, has avoided wear rib perk to get stuck, and wear rib thermal distortion is seized and pulled close arranging pipe.
