Background technique
Metal smelt technology is widely used in China, and especially steel-smelting technology is the project that China endeavours research.
Domestic enterprise mostly uses greatly electric-arc furnace steelmaking mode at present, and electric arc furnaces (abbreviation EAF) steel-making is using electric energy as heat
The method for making steel in source, it be so that electric energy is changed into thermal energy in arc light by the electric arc of generation of discharging between electrode and furnace charge, and by
The direct effect of arc radiation and electric arc heats and melts metal charge and clinker, smelts the steel and alloy of various composition qualification out
A kind of method for making steel.
The filler into furnace is needed in steel-making course of the electric arc furnace, general filler mode is to open bell from top to bottom blanking,
Such mode can not only lose a large amount of thermal energy, but also be easily destroyed the slag layer on surface, so that refining material efficiency reduces, slow down smelting
Refining progress.
Summary of the invention
The technical issues of present invention provides a kind of sealed electric arc furnaces filler device of band, solved is by electric arc furnaces side
Charging reduces heat-energy losses in furnace, improves efficiency.
The present invention, which solves its technical problem, to be achieved through the following technical solutions: with sealed electric arc furnaces filler device,
Including electric arc furnaces, inserted block, belt transport unit and device for discharging, the device for discharging is installed on belt transport unit, skin
It is connected with the fire door of transport device blanking end and electric arc furnaces, the inserted block one side fitting fire door, and bottom and belt transport unit
It is in contact；The two sides of the belt transport unit are additionally provided with bracket, and the bracket is connected with runner, the runner its close to wheel rim
Locate hinged push rod one end, the hinged inserted block top of the push rod other end；The driving wheel of the runner and belt transport unit difference
Connect different driving device.
Further, the device for discharging further includes baffle, fire door is connected at the baffle butt end and is provided with slotting
Slot, the protrusion that two short side of slot is also arranged oppositely.
Further, two side lower part of inserted block is additionally provided with sliding slot, the ledge width phase of trough width and the slot
Adaptation.
Further, the fire door has gradient.
Compared with prior art, the beneficial effects of the present invention are:
1, small to the clinker damage layer on furnace liquid level by the feeding of electric arc furnace sidewall, guarantee the thermal efficiency in smelting process.
2, inserted block setting not only ensure that confined space in furnace well, and moveing freely property also makes filler become more square
Just.

Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
As shown, with sealed electric arc furnaces filler device, including electric arc furnaces 1, inserted block 3, belt transport unit 5 and discharging
Device 7, the device for discharging 7 are installed on belt transport unit 5, the fire door at belt transport unit 5 blanking end and electric arc furnaces 1
2 connections, the inserted block 3 is bonded fire door 2 on one side, and bottom is in contact with belt transport unit 5；The belt transport unit 5
Two sides are additionally provided with bracket, and the bracket is connected with runner 6, its hinged 4 one end of push rod at wheel rim of the runner 6 is described to push away
Hinged 3 top of inserted block of 4 other end of bar；The driving wheel of the runner 6 and belt transport unit 5 is separately connected different driving device.
Above scheme is main scheme for implementing said method, the electric arc furnaces 1 with foundation structure, connects furnace by belt transport unit 5
Filler at mouthfuls 2 is installed on device for discharging 7 on belt transport unit 5, broken furnace charge is discharged into belt by device for discharging 7
On the belt of transport device 5.Belt transport unit 5 is that general belt-conveying structure includes belt, driving wheel and motor, discharging dress
It sets including dump skip and connecting plate.3 front of inserted block or the back side and the upper fire door of fire door 2 fit, and 3 bottom of inserted block and skin
Band transport device 5, which is in contact, to seal, and all structures are all made of heat-resisting material resistant to high temperatures.Above and below realization inserted block 3
The two sides of free movement, the belt transport unit 5 are additionally provided with bracket, and runner 6 is socketed on the bracket.It also cuts with scissors on 3 top of inserted block
It is connected to push rod 4,4 other end of push rod is hinged on runner 6 at wheel rim, and driving runner 6 rotates, and drives push rod 4 to move, in push rod
The up and down motion that inserted block 3 is realized under the action of 4, when 6 turns of a runner complete circles, inserted block 3, which returns to initial position, to be continued to close.Runner 6
