Description
Technical field
The utility model belongs to metallurgical technology field, and in particular to a kind of energy saving and environment friendly molten iron streamer device.
Background technology
, it is necessary to which the high temperature liquid iron that blast furnace is refined is drained into ladle in steel smelting procedure, then enter to advance again
The smelting of one step.Under prior art conditions, it is blast-melted to be directly poured into iron through iron tap channel termination (or by swing spout)
In water bag, molten iron is exposed in air always in this process, without any safeguard procedures.
Due to not carrying out closing protection during the blast-melted injection ladle from iron tap channel (or swing spout), open
Cast is opened, various problems can be caused to occur, including the flue dust of operation field is very big, molten iron and air contact can be oxidized, radiate
Speed is fast, thermal loss is big, temperature drop is big etc..Such in order to solve the problems, such as, there is an urgent need to a kind of energy saving and environment friendly molten iron
Streamer device.
Utility model content
For problems of the prior art, the utility model provides a kind of energy saving and environment friendly molten iron streamer device, should
Device installs additional at iron tap channel termination (or swing spout) between ladle, it is blast-melted through present apparatus streamer in ladle,
Molten iron, in closing keeping warm mode, can be greatly decreased soot emissions using the present apparatus, reduce dissipating for molten iron in whole process
Simultaneously the energy consumption of follow-up STEELMAKING PRODUCTION is greatly reduced in heat loss, the temperature drop for reducing molten iron.
The utility model provides a kind of energy saving and environment friendly molten iron streamer device, including fixed support, upper sleeve pipe and setting of casing,
The fixed support is fixedly mounted on the wall below iron tap channel termination, and the setting of casing is placed in support bracket fastened locating ring
On, the upper sleeve pipe is placed on cased support, the bag mouth of cased outlet alignment ladle.
Further, the upper sleeve pipe and setting of casing are thermal insulation casing.
Further, the thermal insulation casing is made up of box hat, heat-insulation layer and working lining successively from outside to inside.
As a preferred embodiment, the heat-insulation layer uses fire-retardent fiber felt-rug or light weight castable refractory.
As a preferred embodiment, the working lining uses Al2O3- SiC-C castables.
The utility model has the advantages that：
(1) simple in construction, cost is low, makes simply, and it is convenient to change.
(2) the utility model is used, molten iron is from iron tap channel termination (or swing spout) warm sleeve pipe streamer in ladle
In, whole process is in closing keeping warm mode, so as to which soot emissions be greatly decreased, reduces the pollution to environment.
(3) the utility model is used, the thermal loss of molten iron is reduced, and molten iron temperature, which declines, to be reduced, and is advantageous to subsequently make steel
Production reduces energy consumption.
