Description
Technical field
This utility model relates to a kind of flame-thrower nozzle, particularly relates to the quick cutting-off nozzle of a kind of continuous casting steel.
Background technology
It is in steel-making continuous casting cuts, owing to roll casting specification, thickness and the width etc. of steel are not quite similar and widely different,
In continuous casting tapping cutting, all use injection head cutting gun at present, the quality of cutting section be it is also proposed higher requirement, cut
Section requires that smooth, dross to be lacked, and existing continuous casting cutting nozzle is because of its reasons in structure, and its combustion gas flat fire ejection causes firepower not collect
In, not only make that cutting gap is big, facet out-of-flatness, upper turned-down edge, lower dross, and also cutting speed is the highest, power consumption big, cuts into
This height.And slag easily clings cutting torch and blocks and cause tempering phenomenon, cutting torch is fragile.
Utility model content
The purpose of this utility model is to provide a kind of firepower, and greatly and firepower is concentrated, and mixed gas is uniform, and cut quality is high, speed is fast
The mixed oxygen cutting mouth of continuous casting steel.
The technical solution of the utility model is:
The quick cutting-off nozzle of a kind of continuous casting steel, cutting head includes outer sleeve (1) and mouth core pipe (2), and mouth core pipe (2) inserts
On outer sleeve (1)；Described mouth core pipe (2) epimere is a short tube (21), and the top of short tube (21) is provided with outer cone slope
(211), interior mouthpiece is provided with infundibulate air intake (212)；Described mouth core pipe (2) intermediate projections has bulge loop one (22) and bulge loop two
(23), bulge loop one (22) diameter is more than bulge loop two (23) diameter, and two bulge loops are connected, and bulge loop one (22) and bulge loop two (23) are upper longitudinally
And it is provided with a circle gas circulation hole (231) around short tube (21)；Described mouth core (2) hypomere is provided with the gas diversion of some circumferential projection
Sheet (24), is formed with gas circulation groove (240) between gas diversion sheet (24), the top of every gas diversion sheet (24) is provided with tiltedly
Slope wall (241)；It is reserved with combustion gas mixing portion (25) between described gas diversion sheet (24) and bulge loop two (23)；Described outer sleeve
(1) bottom is provided with flame jet (11).
The mixed oxygen cutting mouth of a kind of continuous casting steel of the present utility model has the beneficial effect that this product structure is simple, practicality
By force, firepower is concentrated and violent, and firepower condenses, temperature high, fire distance, and cutting speed is fast, and precision is high, and face is smooth, steel billet edge
Not dross, cutting torch is long for service life.

Detailed description of the invention
The quick cutting-off nozzle of a kind of continuous casting steel, cutting head includes outer sleeve 1 and mouth core pipe 2, and mouth core pipe 2 is inserted in overcoat
On cylinder 1；Described mouth core pipe 2 epimere is a short tube 21, and the top of short tube 21 is provided with outer cone slope 211, and interior mouthpiece is provided with funnel
Shape air intake 212, this air intake 212 is oxygen air intake, and infundibulate air intake 212 convenient docking oxygen hose and connection seal；
Described mouth core pipe 2 intermediate projections has bulge loop 1 and bulge loop 2 23, and bulge loop 1 diameter is more than bulge loop 2 23 diameter, two bulge loop phases
Even, after mouth core pipe 2 is inserted in outer sleeve 1, between outer sleeve 1 top margin top belling ring 1 and bulge loop 2 23 on step, bulge loop two
23 stretch in sleeve, and bulge loop 1 and bulge loop 2 23 longitudinally and are provided with a circle gas circulation hole 231 around short tube 21；Described mouth
Core 2 hypomere is provided with the gas diversion sheet 24 of some circumferential projection, is formed with gas circulation groove 240, often between gas diversion sheet 24
The top of sheet gas diversion sheet 24 is provided with sloped wall 241；It is reserved with combustion gas between described gas diversion sheet 24 and bulge loop 2 23 to mix
Conjunction portion 25, combustion gas enters from gas circulation hole 231, mixes in combustion gas mixing portion 25, and combustion gas is walked downward from gas circulation groove 240；
It is provided with flame jet 11, when combustion gas flow to gas circulation groove 240 end, bottom, in flame jet 11 shape bottom described outer sleeve 1
Become strength flame flame.
The foregoing is only preferred implementation of the present utility model, on protection domain of the present utility model is not limited in
Stating embodiment, every technical scheme belonging to this utility model principle belongs to protection domain of the present utility model.For this
For the technical staff in field, the some improvements and modifications carried out on the premise of without departing from principle of the present utility model, these
Improvements and modifications also should be regarded as protection domain of the present utility model.
