Description
Technical field
The invention belongs to field of iron and steel smelting, and in particular to a kind of blast furnace iron outlet groove cooling device.
Background technique
Blast furnace iron outlet groove is the channel that high temperature liquid iron and slag flow through, and as blast furnace develops to enlargement, the logical iron time prolongs
Long, tapping interval time shortens, and the quality and service life to blast furnace iron outlet groove propose harsher requirement.Due to high temperature liquid iron
With the presence of slag, often there is apparent temperature gradient in the structures such as the resistance to material 8 of iron runner and steel shell, it is therefore desirable to carry out to iron tap channel
It is cooling.The relatively common type of cooling is that cooling duct is arranged in iron tap channel bottom at present, by be passed through cold air or cold water into
Row cooling down.However when using traditional type of cooling, due to the different architectural characteristic of iron tap channel, the cold air being passed through or cooling
Water is distributed and uneven in cooling duct, causes entire iron tap channel thermo parameters method uneven, there are apparent high-temperature regions.?
In the periodic production process of iron tap channel, being influenced by temperature change, corresponding change can occur for the material properties of different materials,
Phenomena such as to crack under Long Time Thermal impact, lead to structure spalling, to seriously affect the stable operation of iron tap channel
And service life, or even the operation of entire blast furnace is influenced, bring weight huge economic loss.
Summary of the invention
In view of this, the purpose of the present invention is to provide a kind of blast furnace iron outlet groove cooling device, to solve existing iron tap channel
Cooling effect is bad, the uneven problem easy to crack so as to cause iron tap channel of iron tap channel thermo parameters method.
In order to achieve the above objectives, the invention provides the following technical scheme: a kind of blast furnace iron outlet groove cooling device, including cooling
Supervisor further includes the part flow arrangement and partition being connected with cooling supervisor；The arrival end of part flow arrangement is connected with cooling supervisor, shunts
Multiple outlet ends of device are connected with each cooling branch pipe respectively；Several partitions are arranged in iron tap channel cooling duct and will go out
Iron runner cooling duct is separated into multiple independent sub-channels, and each independent sub-channel is correspondingly connected with each cooling branch pipe respectively.
It further, further include blower, blower setting is on cooling supervisor.
Further, flow control valve is correspondingly provided on each cooling branch pipe.
It further, further include thermometer and control cabinet, thermometer is correspondingly arranged in each independent sub-channel and and control cabinet
Electrical connection, control cabinet are electrically connected with flow control valve.
Further, part flow arrangement has multiple, is arranged in parallel on cooling supervisor.
Further, part flow arrangement can be tee tube or four-way pipe etc..
The beneficial effects of the present invention are: cold air total amount in entire iron tap channel air duct is controlled by Fan Regulation, is passed through
Part flow arrangement and the cooling air quantity of flow control valve independent control difference outlet.Partition is set in iron tap channel cooling air channel simultaneously
Numerous independent sub-air channels are formed, and part flow arrangement is exported by cooling branch pipe and is connected with independent sub-air channel, reach independent
Control the purpose of different air duct cooling air quantities.The device can satisfy the equally distributed requirement of iron tap channel air duct flow field, can also
With according to live iron tap channel temperature monitoring data, cooling air quantity in flexible modulation difference air duct, to make temperature in iron tap channel
It is more uniform reasonable to be distributed, and effectively iron tap channel is inhibited to occur the phenomenon that cracking because of non-uniform temperature, ensure that iron tap channel height
Effect, stable operation, extend iron tap channel service life.Meanwhile the cooling device applies also for different engineering site arbitrary shapes
The iron tap channel structure of formula has wide applicability.
Detailed description of the invention
In order to keep the purpose of the present invention, technical scheme and beneficial effects clearer, the present invention provides following attached drawing and carries out
Illustrate:
Fig. 1 is the structural diagram of the present invention；
Wherein: cooling supervisor -1, blower -2, blast pipe -3, part flow arrangement -4, flow control valve -5, cooling branch
Manage -6, partition -7, the resistance to material -8 of iron runner, subchannel -9.
Specific embodiment
Below in conjunction with attached drawing, a preferred embodiment of the present invention will be described in detail.
As shown, the blast furnace iron outlet groove cooling device in the present invention, including cooling supervisor 1, further include and cooling supervisor 1
Connected part flow arrangement 4 and partition 7；Wherein the arrival end of part flow arrangement 4 is connected with cooling supervisor 1, part flow arrangement 4 it is multiple out
Mouth end is connected with each cooling branch pipe 6 respectively；Several partitions 7 are arranged in iron tap channel cooling duct and lead to iron tap channel cooling
Road is separated into multiple independent subchannels, and each independent sub-channel is correspondingly connected with each cooling branch pipe 6 respectively.
In the cooling device, iron tap channel cooling duct is separated into multiple independent sub-channels by partition 7, and part flow arrangement 4 will be cold
But the cooling medium (coolant liquid or cooling gas) in supervisor 1 is divided into multichannel, and each road cooling medium correspondence is conveyed into one group or more
To cool down to it in the cooling subchannel of group iron tap channel, which can improve point of coolant flow field in iron tap channel cooling duct
Cloth uniformity simultaneously meets the requirements it, to inhibit the phenomenon that iron tap channel occurs cracking because of non-uniform temperature, guarantees iron tap channel
Efficiently, stable operation extends iron tap channel service life.
As a further improvement of the foregoing solution, further include thermometer and control cabinet, be correspondingly provided on each cooling branch pipe 6
Flow control valve 5.Thermometer is correspondingly arranged in each independent sub-channel and is electrically connected with control cabinet, control cabinet and flow control valve
