Towed ladle ferrum bag apparatus for baking of the present invention includes that seat 2 fixed by mobile base 1 and ladle, and seat fixed by ladle
Arranging at least 2 ladle locating supports 3 on 2, mobile base 1 can fix seat 2 closer or far from ladle, on mobile base 1 with
The position of each ladle locating support 3 correspondence respectively sets a lid 4, is all interconnected by hot blast pipe network between each lid 4, hot blast
In in pipe network, installation air-heater and hot blast control valve door, air-heater and hot blast control valve door can make any one lid 4
Steam enter in other lid 4 by hot blast pipe network 5, each lid 4 is respectively provided with burner 6, each burner 6 all with gas piping 7
Connecting with air line 8, gas piping 7 arranges control valve for coal gas 9 near one end of each burner 6, and air line 8 is near each burner
One end of 6 arranges air shut-off valve 10, and each lid 4 all connects with exhaust stack 18, and each exhaust stack 18 is respectively provided with diffusion valve 21.This
Invention can arrange many group burners 6 on lid 4, and the quantity of burner determines according to the diameter of ladle or ferrum bag.The mobile end
Seat 1 is when seat 2 fixed by ladle, and the ladle on each self-corresponding ladle locating support 3 or ferrum can be encapsulated and close by each lid 4,
When mobile base 1 fixes seat 2 away from ladle, each lid 4 divides with the ladle on each self-corresponding ladle locating support 3 or ferrum bag
From.During use, the burner 6 on any one lid 4 burns, and the diffusion valve 21 of this lid 4 is closed simultaneously, corresponding to this lid 4
Ladle or the ferrum bag of position toast, and the burner 6 of remaining lid 4 is turned off control valve for coal gas 9 and air shut-off valve 10 and beats
Open diffusion valve 21, after ladle or ferrum bag are toasted by the hot blast that the burner 6 carrying out toasting produces, enter it by hot blast pipe network
Other ladle or ferrum bag are preheated by its ladle of lid 4 correspondence or the waste heat of ferrum bag, beneficially hot blast, straight by burner 6
Connect the ladle of baking or temperature, generally at 1000 DEG C-1100 DEG C, now utilizes this ladle or the heat of ferrum bag time ferrum bag has toasted
Wind carries out the temperature of ladle or the ferrum bag preheated and also can reach 600 DEG C-800 DEG C, after ladle or ferrum bag have toasted, will toast
The ladle or the ferrum bag that become hang away, then the ladle to be baked that new is placed in this position, the ladle being preheated before now starting
Or the burner 6 on lid 4 corresponding to ferrum bag, close the diffusion valve 21 of this lid 4, the burner 6 of remaining lid 4 is turned off coal gas control
Valve 9 processed and air shut-off valve 10 also open diffusion valve 21, start new baking process, and this baking process can be from 600 DEG C-800 DEG C
Left and right starts to warm up, and also utilizes the waste heat of hot blast to preheat other ladle or ferrum bag with stylish baking process, above-mentioned baking
Roasting process alternately, with existing burner compared with ladle or ferrum bag roasting plant one to one, each ladle of the present invention
Average baking time can foreshorten to 3 days from 7 days, greatly improve baking efficiency, effectively enhance the utilization ratio of heat energy, heat
Gas exhaust temperature have also been obtained reduction further, is effectively reduced the impact on ambient temperature, and each burner 6 is spaced work, will not
It is chronically in the working environment of high-temp combustion, is conducive to extending the service life of burner 6.Ladle of the present invention or ferrum bag and lid
Take the connected mode of pressure-bearing type between 4, vertical steel ladle baking device issuable hot blast short circuit problem can be prevented effectively from.
Mobile base 1 of the present invention can use various structures to realize moving back and forth, for example with motor-driven walking
Wheel etc., but the degree of accuracy of these structures is slightly worse, situation about skidding easily occurs, and the present invention moves base 1 and moves back and forth preferably
Structure is: arranges guide rail 11 below described mobile base 1, arranges road wheel 12, road wheel 12 and guide rail 11 bottom mobile base 1
Coordinating, mobile base 1 is connected with the piston rod of hydraulic cylinder 13.The advantage that this structure has registration compared with other structure.
Hot blast pipe network of the present invention can use various structures, and wherein preferably structure is: all pass through between adjacent caps 4
Hot air duct 5 connects, and each hot air duct 5 is respectively mounted forward air-heater 14, forward hot blast control valve door 15, reverse hot blast wind
Machine 16, reverse hot blast control valve door 17, wherein forward air-heater 14, forward hot blast control valve door 15 and reverse air-heater
