Description
Technical field
A kind of device for removing steel billet burr is the utility model is related to, especially small billet removes the device of flash removed, belonged to
Metallurgy industry continuous casting installation for casting technical field.
Background technology
In steelmaking process, the mode scale segmentation of continuous casting billet generally use gas flame cuttiug, to meet rolling mill practice
Needs.In continuous casting billet flame cutting process, when melting metal and flowing through otch lower surface, the projection of inverted triangle shape is formed, is referred to as
Burr.Burr it is sophisticated sharp keen, the transporting equipments such as roller table surface can be scratched in the transportation of steel billet, if burr is not gone
Remove, scar can be formed in square billet end during cogging, if sheared length is inadequate, can cause to sentence useless, influence mill bar quality
And recovery rate.
At present, the removal device of burr is to install pendulum or scraper in the bottom of the ejection roller way of continuous casting billet, passes through pendulum
Or scraper removes the burr on steel billet, this appliance arrangement volume is big, and pneumatically or hydraulically control system is cumbersome, especially for small
Square billet, due to installing space deficiency, the problem of can not installing be present.
Utility model content
The utility model purpose is to provide a kind of device for removing steel billet burr, can thoroughly remove the burr on steel billet,
Prevent damage of the steel billet burr to roller-way, improve mill bar quality and recovery rate, solve problem present in background technology.
The technical solution of the utility model is：
A kind of device for removing steel billet burr, includes air valve system, oxygen hose, nitrogen flexible pipe, moving cart and burning torch
Shower nozzle, the burning torch shower nozzle include inner and outer tubes, and on inner pipe, inner and outer tubes pass through oxygen hose and nitrogen to outer tube sleeve respectively
Gas flexible pipe is connected with air valve system, and the oxygen hose, nitrogen flexible pipe and burning torch shower nozzle are each attached in moving cart.
Oxygen gauge, nitrogen pressure table, oxygen control valve and nitrogen gas control valve are provided with the air valve system.
The moving cart and burning torch shower nozzle are located at the lower section of ejection roller way, and the jet direction of burning torch shower nozzle is towards on steel billet
Burr.
Asbestos cloth is respectively equipped with oxygen hose and the nitrogen flexible pipe.
Using the utility model, moving cart and burning torch shower nozzle be arranged on to the lower section of ejection roller way, and and cutting after
Steel billet moves together, while moving cart along steel billet transverse shifting, can also make the jet direction of burning torch shower nozzle be directed at steel always
Burr on base, oxygen control valve and nitrogen gas control valve in air valve system are opened, the oxygen sprayed by the inner tube of burning torch shower nozzle
Burr on gas fusing steel billet, then the nitrogen for the outer tube ejection for passing through burning torch shower nozzle will be blown down to molten metal burr.
The beneficial effects of the utility model are：The burr on steel billet can be thoroughly removed, prevents steel billet burr to roller-way
Damage, improve mill bar quality and recovery rate.Small volume, it is easy to install.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is the utility model burning torch shower nozzle front view；
Fig. 3 is the utility model burning torch shower nozzle side view；
In figure：Air valve system 1, oxygen hose 2, nitrogen flexible pipe 3, moving cart 4, burning torch shower nozzle 5, inner tube 6, outer tube 7, oxygen
Atmospheric pressure table 8, nitrogen pressure table 9, oxygen control valve 10, nitrogen gas control valve 11.
Embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
Referring to the drawings 1,2,3, a kind of device for removing steel billet burr, air valve system 1, oxygen hose 2, nitrogen flexible pipe are included
3rd, moving cart 4 and burning torch shower nozzle 5, the burning torch shower nozzle 5 include inner tube 6 and outer tube 7,7 sets of outer tube on the inner tube 6, the He of inner tube 6
Outer tube 7 is connected by oxygen hose 2 and nitrogen flexible pipe 3 with air valve system 1 respectively, the oxygen hose 2, nitrogen flexible pipe 3 and is cut
Gun sprayer 5 is each attached in moving cart 4.
In the present embodiment, air valve system 1 is an air valve station, and oxygen gauge 8, nitrogen pressure table are provided with air valve station
9th, oxygen control valve 10 and nitrogen gas control valve 11, it can monitor and control in real time the oxygen in the inner tube 6 and outer tube 7 of burning torch shower nozzle
With the pressure of nitrogen, so as to control blow down air-flow width and length, to adapt to the section dimension requirement of different steel billets.And pass through
Nitrogen pressure sensor is set, detects whether thoroughly to blow down burr.Wound on the outer surface of oxygen hose 2 and nitrogen flexible pipe 3
Asbestos cloth, to prevent casting billet surface high temperature from burning out flexible pipe.
In use, moving cart 4 and burning torch shower nozzle 5 are arranged on the lower section of ejection roller way, make the jet direction of burning torch shower nozzle 5
Moved together towards the burr on steel billet, and with the steel billet after cutting, pass through the oxygen molten steel that the inner tube 6 of burning torch shower nozzle sprays
Burr on base, then the nitrogen for the ejection of outer tube 7 for passing through burning torch shower nozzle will be blown down to molten metal burr.If nitrogen or oxygen
The pressure of gas is not reaching to setting value, then by moving cart transverse shifting, to reach the purpose for thoroughly removing flash removed.
