Abstract
This utility model provides a kind of double venturi mouth of a river preheating furnace structure, and including the river diversion tee joint pipe of an inverted T-shaped, the upper end of described river diversion tee joint pipe is arrival end, and described arrival end connects continuous casting intermediate inlet；The both sides of described river diversion tee joint pipe are the port of export, and the described port of export connects Venturi tube, and two ports of export are symmetrical arranged and respectively install a compressed air hose and are passed through compressed air water conservancy diversion.This utility model can effectively shorten continuous casting intermediate inlet preheating time, and more single Venturi tube mouth of a river preheating furnace is compared, and after using double venturi mouth of a river preheating furnace, the mouth of a river will reduce 1/3 preheating time.Ensureing that the mouth of a river uniformly preheats simultaneously, after using double venturi mouth of a river preheating furnace, use infrared thermometer detection, mouth of a river outer surface is without the obvious temperature difference.
Description
Technical field
This utility model relates to field of metallurgy；
Particularly relate to a kind of double venturi mouth of a river preheating furnace structure.
Background technology
Venturi tube is the abbreviation of Venturi tube, and the principle of Venturi effect is then when blowing air over obstacle, at obstacle
Lee face above near ports air pressure relatively low, thus produce adsorption and cause the flowing of air.Venturi tube former
Reason is the simplest, and it is exactly air-flow from the coarse to fine, to accelerate gas flow rate, makes gas be formed at the rear side of venturi outlet
One " vacuum " district.
Single venturi tube structure all taked by existing mouth of a river preheating furnace, is passed through Venturi tube by compressed air, guides hot-fluid centering
Between water-coating port carry out Baking out.Its heat time heating time is longer, uniformity coefficient is the most impacted.
Utility model content
All deficiencies of prior art in view of the above, the technical problems to be solved in the utility model is to provide one
Double venturi mouth of a river preheating furnace structure, to overcome the drawbacks described above of prior art.
For achieving the above object and other relevant purposes, this utility model provides a kind of double venturi mouth of a river preheating furnace knot
Structure, including the river diversion tee joint pipe of an inverted T-shaped, the upper end of described river diversion tee joint pipe is arrival end, and described arrival end connects in continuous casting
Between water-coating port；The both sides of described river diversion tee joint pipe are the port of export, and the described port of export connects Venturi tube, and two ports of export are symmetrical arranged
And a piece compressed air hose of each installation is passed through compressed air water conservancy diversion.
Preferably, described continuous casting intermediate inlet is inserted with mouth of a river preheating furnace.
Preferably, described compressed air hose is provided with control valve.
Preferably, described Venturi tube passes through Flange joint on river diversion tee joint pipe.
Preferably, 2/3rds of a length of river diversion tee joint pipe cross-directional length of described Venturi tube.
By above technical scheme, this utility model has following technical effect that this utility model compared to prior art
Can effectively shorten continuous casting intermediate inlet preheating time, more single Venturi tube mouth of a river preheating furnace is compared, and uses the double venturi mouth of a river
After preheating furnace, the mouth of a river will reduce 1/3 preheating time.Ensure that the mouth of a river uniformly preheats simultaneously, after using double venturi mouth of a river preheating furnace,
Use infrared thermometer detects, and mouth of a river outer surface is without the obvious temperature difference.
Accompanying drawing explanation
Fig. 1 is shown as structural representation of the present utility model.
Element numbers illustrates:
1 river diversion tee joint pipe
2 Venturi tubes
3 compressed air hoses
Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model being described below, those skilled in the art can be by this
Content disclosed by description understands other advantages of the present utility model and effect easily.
Refer to Fig. 1.It should be clear that structure depicted in this specification institute accompanying drawings, ratio, size etc., the most only in order to coordinate
Content disclosed in description, understands for those skilled in the art and reads, and being not limited to this utility model can be real
The qualifications executed, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or the tune of size
Whole, under not affecting effect that this utility model can be generated by and the purpose that can reach, all should still fall in this utility model institute
In the range of the technology contents disclosed obtains and can contain.Meanwhile, in this specification cited as " on ", D score, "left", "right",
The term of " middle " and " one " etc., is merely convenient to understanding of narration, and is not used to limit the enforceable scope of this utility model,
Being altered or modified of its relativeness, is changing under technology contents without essence, when being also considered as the enforceable category of this utility model.
Refering to shown in Fig. 1, this utility model provides a kind of double venturi mouth of a river preheating furnace structure, including leading of an inverted T-shaped
Stream tee T 1, the upper end of river diversion tee joint pipe 1 is arrival end, and described arrival end connects continuous casting intermediate inlet, Continuous Casting Water
Mouth is inserted with mouth of a river preheating furnace.The both sides of river diversion tee joint pipe 1 are the port of export, and the described port of export connects Venturi tube 2, two Venturi tubes
2 are all connected with preheating furnace and communicate.Two ports of export are symmetrical arranged and respectively install a compressed air hose 3 and are passed through compressed air and lead
Stream, compressed air hose 3 is provided with control valve, it is ensured that the admission pressure on both sides is the same.Before continuous casting produces, first tundish is hung
Put to tundish car, install the mouth of a river, regulate centralising device, and by tundish car lifting, continuous casting intermediate inlet is inserted
Preheating furnace center, the mouth of a river.Baking is started after falling baking of tundish device.The baking preheating of continuous casting intermediate inlet is with middle
Bag toasts pre-hotsync to be carried out.Meanwhile, open mouth of a river preheating furnace compressed air, baking of tundish hot-fluid is set by lateral symmetry
The Venturi tube put is drawn, and both sides guide hot-fluid to carry out Baking out simultaneously, it is ensured that uniformly, reaches to toast the purpose at the mouth of a river.
As further improvement of the utility model, Venturi tube 2 Flange joint or be fixedly welded on river diversion tee joint pipe 1.
2/3rds of a length of river diversion tee joint pipe 1 cross-directional length of Venturi tube 2.
In sum, this utility model can effectively shorten continuous casting intermediate inlet preheating time, more single Venturi tube mouth of a river
Preheating furnace is compared, and after using double venturi mouth of a river preheating furnace, the mouth of a river will reduce 1/3 preheating time.Ensure that the mouth of a river is the most pre-simultaneously
Heat, after using double venturi mouth of a river preheating furnace, uses infrared thermometer detection, and mouth of a river outer surface is without the obvious temperature difference.So, this
Utility model effectively overcomes various shortcoming of the prior art and has high industrial utilization.
Above-described embodiment only illustrative principle of the present utility model and effect thereof are new not for limiting this practicality
Type.Above-described embodiment all can be carried out by any person skilled in the art under spirit and the scope of the present utility model
