Description
Technical field
Technical field of auxiliary equipment, more particularly to a kind of dress for clearing up electric arc furnaces fire door slag are smelted the present invention relates to molten steel
Put.
Background technology
At present, during most of steel-casting foundry's electric-arc furnace steelmakings, before the heat of oxidation starts, arc furnace need to be risen
Door, condenses the slag to be formed in the molten steel of stove gate by melting stage splash or spilling and gets rid of, and sends into stove, to ensure continuous oxygen
Rifle smoothly out of the insertion of arc furnace doorway stove, completes oxygen blast.
The method that tradition removes arc furnace doorway slag, is to be assisted mutually by several operative employees, uses long 4m or so
The instrument such as oxygen lance, molten steel condensation slag sled is removed.Because electric arc furnaces melting stage splash or spilling molten steel duration are longer,
Molten steel can slow cooling Layer by layer solidification, so condensed slag is bonded at stove gate, size is very big, tend to reach 500mm~
600mm, is fallen a bulk of slag sled with manpower, especially arduously, time-consuming, and is risen electric arc furnaces fire door for a long time and can also be caused electricity
Arc stove dissipated heat is big, increases power consumption, meanwhile, because molten steel temperature is up to 1600 DEG C or so in arc furnace, operative employee prizes slag
When it is nearer from fire door, so molten steel heat radiation injures very big to operative employee, and when slag is prized, may occur in stove
Collapse material, causes high-temperature molten steel to be spilt from arc furnace doorway, if operative employee hides too late, easily occurs security incident.
The content of the invention
The present invention proposes that one kind can improve slag cleaning efficiency, save manpower, avoid electric arc furnaces molten steel in the stove to operation
Work produce fire damage, the splash that causes of material of collapsing in reduction stove hurt sb.'s feelings risk cleaning electric arc furnaces fire door slag device.

Embodiment
Referring to Fig. 1 to Fig. 3, the device of electric arc furnaces fire door slag, including crowbar portion 1, supporting part 2, fixed part 3, sled are cleared up
The tail end in thick stick portion 1 is fixed on supporting part 2, and the tail end of supporting part 2 is fixedly connected with fixed part 3, and crowbar portion 1 includes elongated sled stove
Door rod 10, the tail end of sled fire door bar 10 sets positioning through hole 211, and supporting part 2 includes support baseboard 20, locating cover 21, fixing groove
24, locating cover 21 is fixed on the upper surface of support baseboard 20, is formed between locating cover 21 and support baseboard 20 and is accommodated sled fire door
The space of the tail end insertion of bar 10, fixing groove 24 is fixed on the lower surface of support baseboard 20, opened on the top surface of locating cover 21
If positioning through hole 211, positioning through hole 211, positioning through hole 211, the support baseboard of locating cover 21 are also opened up on support baseboard 20
20 positioning through hole, the positioning through hole of sled fire door bar 10 are at least two, the positioning through hole 211 of at least two locating covers 21,
It is just right up and down between the positioning through hole of at least two support baseboards 20, the positioning through hole of the tail end of at least two sled fire door bars 10,
And coaxial same footpath, fixing groove 24 is to be fixedly installed on the lower surface of support baseboard 20 to put down with prizing the length direction of fire door bar 10
Capable elongated slot, fixing groove 24 is two, and fixed part 3 includes two pieces of fixed boards be arrangeding in parallel, respectively the first fixed board
30 and second fixed board 31, the first fixed board 30 is vertical with the tail end of support baseboard 20 to be fixedly connected, and fixes vertical first
Screw 32 is opened up on plate 30, the position faced in the screw 32 of the second fixed board 31 and the first fixed board 30 also opens up spiral shell
Hole, connection is detachably fixed between the first fixed board 30 and the second fixed board 31 by inserting bolt.
Further, the width of support baseboard 20 is more than the two of the fork truck for the device for being used for mobile cleaning electric arc furnaces fire door slag
The distance between individual jaw.So that the device for clearing up electric arc furnaces fire door slag to be placed to two installed in fork truck by support baseboard 20
On individual jaw.
Further, locating cover 21 is fixed on the center line of the width of the upper surface of support baseboard 20.When sled fire door bar
During 10 insertion locating cover 21 on the center line in support baseboard 20, so ensure the uniform force of support baseboard 20, whole cleaning electricity
The device of arc furnace door slag is in stress balance position.
Wherein, the U-type groove that locating cover 21 is made up of three pieces of flat boards, the opening relative with the bottom land of U-type groove is fixed on branch
Support on bottom plate 20, one piece of closure flat board 22 is fixed at the opening of the tail end of sled fire door bar 10 in U-type groove.Such U-type groove with
The receiving space for the insertion of sled fire door bar 10 is formed between support baseboard 20, because that prizes that fire door bar 10 bears in real work touches
Hit that power is very big, closure flat board 22 can further avoid the tail end for prizing fire door bar 10 from being ejected from locating cover 21.
Further, two pieces of reinforcing plates 23 are fixed between closure flat board 22 and support baseboard 20, reinforcing plate 23 is shaped as
Isosceles right triangle, two right-angle sides of each reinforcing plate 23 are fixedly connected with closure flat board 22, support baseboard 20 respectively.From
And further strengthen blocking the barrier force of the tail end of 22 pairs of sled fire door bars 10 of flat board.
Further, sled fire door bar 10 is slender cylinder or elongated oval cylinder.Because the length of sled fire door bar 10 is about
4m, on the jaw for be fixed on fork truck during mobile working, impact force when tapping the slag of stove gate is very big, cylinder or ellipse
Cylinder is smooth due to its surface, the position concentrated in the absence of stress or weak spot, reduces what sled fire door bar 10 bent or damaged
Risk.
Further, the front end of sled fire door bar 10 is cone 101, the round and smooth mistake of body of cone 101 and sled fire door bar 10
Cross, the drift angle of cone 101 is fillet.The design of fillet reduces the contact area of sled fire door bar 10 and slag, and stress is concentrated.
It is safer when the drift angle for being compared to cone 101 is wedge angle, because if during operative's error, fire door bar 10 will be prized
When the shaft of body of heater is arrived on imprudence top, shaft bursting can be caused security incident by wedge angle, so considering, by drift angle
Being made fillet, not only efficiency is high and safer.
Further, because the length for prizing fire door bar 10 is longer, conduct oneself with dignity heavier, its weight is supported in order to stablize, and in order to
Fully contact to support the weight of sled fire door bar 10 with the jaw of fork truck, the length of support baseboard 20 is the length for prizing fire door bar 10
At least the 1/4 of degree, the length of locating cover 21 is at least the 3/4 of the length of support baseboard 20.
During using the present invention, two jaws of fork truck are stretched into two fixing grooves 24 so that the first fixed board 30 with
The inner side of the side wall of jaw is closely pressed close to, then the outside of the second fixed board 31 and the side wall of jaw is closely pressed close to, by screw rod
Tightened in the screw for inserting the first fixed board 30 and the second fixed board 31, device is fixed on jaw, then moved
The jaw of fork truck, will prize the slag that fire door bar 10 is inclined upwardly just to electric arc stove gate, is pushed away, head into furnace interior, such as
It is cleaned at this stove gate blocked originally by slag, then continuous oxygen rifle can be just stretched into body of heater from stove gate and blown
Oxygen.
