Description
Technical field
The utility model, which is related to, belongs to process for making and field of Environment Protection, and more particularly to LF stoves feed silk station dust arrester.
Background technology
LF (Ladle Furnace, ladle furnace) stove is the refining equipment grown up in Japan the initial stage seventies, equipment letter
Single, investment cost is low, and operation is flexibly widely used and developed well with refining effect.Steel grade handled by LF stoves is almost
It is related to all steel grades from special steel to general steel, in production the need for visual quality control, using different technological operating systems.
LF stove technical process：
(1) ladle that converter is tapped in driving is hung on refined molten steel tank car, is connected ladle BOTTOM ARGON BLOWING and is quickly connect
Head, starts Argon；
(2) refined molten steel tank car is opened to heating station, falls ladle bell, and thermometric, sampling are fallen electrode and heated,
And slag charge is added portionwise.
(3) heating is reached after predetermined value, is had a power failure and is carried out alloy regulation, and alloy regulation finishes progress thermometric, sampling.
(4) fall electrode to add after heat, ladle car is opened to silk station is fed, carried out feeding at silk according to steel grade quality requirement
Reason.
(5) after hello silk has been handled, several minutes of progress molten steel of molten steel strong mixing take off [S], further make molten steel composition, temperature equal
Homogenize, and input carbonization rice husk or other heat preserving agents into ladle.
In LF stoves feed silk processing procedure, the vapour pressure of the calcium constituent in silk volume is higher, easily vaporization, following and diffuse into
Calcium bubble floating in molten steel is to slag-gold interface or slag-vapor interface；Calcium constituent easily with FeO, Al2O3、SiO2And oxygen reaction is simultaneously
Big calorimetric is released, the calcium line top of the slag is fed and splashes, produce volume of smoke.
The LF stoves of most domestic steel mill are only provided with the 4th hole or mobile cover dedusting method in refining position, but in soft blow rank
Duan Jinhang does not set dust excluding hood when feeding silk operation, easily produces substantial amounts of flue dust when feeding silk at the scene, not only Field Force is good for
Health constitutes a threat to, and also affects the operation sight of driving personnel in workshop.
Utility model content
The utility model provides a kind of LF stoves and feeds silk station dust arrester, and setting movement on silk station is fed for two in LF stoves
Dust removal installation, not only solves and feeds generation volume of smoke problem during silk, and improve the security of driving plant operations.
A kind of LF stoves described in the utility model feed silk station dust arrester, and movable dust removal cover is half overhead arrangement, described
Movable dust removal covers on aerial conveyor, run on ground rail, and aerial conveyor is arranged on LF stove platforms, and ground rail is arranged in ground
Level ground.
Preferably, the movable dust removal is moved between covering on the position fed between silk position and handling ladle.
Preferably, the movable dust removal cover body is divided into two layers, and it is thick inside to set 25~60mm of heat shield liner, outside for steel plate 12~
16mm is thick.
Preferably, the movable dust removal cover is driven using reducing motor.
The utility model creatively proposes to set half overhead system movable dust removal cover, technique on two hello silk stations of LF stoves
With it is rational in infrastructure, solve the problems, such as well feed silk during produce flue dust.It is mainly to understand that LF stoves, which feed silk station dust removal installation,
Enter soft blow after certainly refining and feed the flue dust produced during wire process, and improve the security of driving plant operations.This practicality is new
Type is not only suitable for newly-built workshop, is also suitable for the upgrading of existing steelshop, there is good application prospect, good economy
Benefit and social benefit, it is very worth to be subject to promotion and application in steel mill upgrading project from now on.

Embodiment
Embodiment described in the utility model described below with reference to the accompanying drawings.One of ordinary skill in the art can recognize
Know, can be with a variety of modes or its combination to institute in the case of without departing from spirit and scope of the present utility model
The embodiment of description is modified.Therefore, accompanying drawing and description are inherently illustrative, rather than for limiting claim
Protection domain.In addition, in this manual, accompanying drawing is drawn not in scale, and identical reference represents identical portion
Point.
The present embodiment is described in detail with reference to Fig. 1-3.
Ladle 4 after tapping is hung on ladle car 3 by shop traveller 7, and ladle car 3 is travelled along tank car track 5
Progress double refining operation is stopped to the refining of LF furnace bodies 6 position.After refining treatment is complete, ladle car 3 returns to 1# along tank car track 5
Feed silk position to stop, movable dust removal cover 1 moves to 1# hello silks position along the high rail 9 on low rail 2 and high trestle 8 and stopped, electric butterfly valve
