Abstract

The invention relates to the maintenance of a quenching furnace, a tempering furnace and a normalizing furnace, in particular to the replacement of burners of the quenching furnace, the tempering furnace and the normalizing furnace. A device for replacing lower rows of burners of the quenching furnace, the tempering furnace and the normalizing furnace comprises a support, two elevating chain blocks and a horizontally moving chain block link, wherein the support comprises cross beam; one end of the cross beam is erected on a furnace wall; the other end of the cross beam is provided with an A-shaped support frame; the two elevating chain blocks are connected with the cross beam in a right-left moving manner; and the horizontally moving chain block link is fixed on a cross rod of the A-shaped support frame. The burners can be elevated or laid down through the elevating chain blocks and can be pulled out or pushed in through the horizontally moving chain block link, so that the lower rows of burners are replaced quickly and safely.

Description

Glowing furnace, tempering furnace and normalizing furnace are arranged burner more changing device and replacing method down
Technical field
The present invention relates to the maintenance of glowing furnace, tempering furnace and normalizing furnace, relate in particular to the replacing of a kind of glowing furnace, tempering furnace and normalizing furnace burner.
Background technology
Glowing furnace, normalizing furnace and tempering furnace on the smelter Wide and Thick Slab steel rolling finishing heat-treatment lines divide the two rows burner, but because next arranges burner below flat board, and burner general stove when changing all is also producing sometimes of heat.Temperature is very high, and the position is bad.Overhead also has the distance more than 1.5 meters.Whole burner has about 100 kilograms.Adopt the people directly to draw to be easy to scald the people and speed is very slow with crowbar sledge scheme.
Summary of the invention
The present invention is intended to address the aforementioned drawbacks, and provides and arranges burner more changing device and replacing method under a kind of glowing furnace, tempering furnace and the normalizing furnace.The present invention can guarantee this project of completion of highly effective and safe.
The present invention is achieved in that and arranges more changing device of burner under a kind of glowing furnace, tempering furnace and the normalizing furnace that it comprises:
A support, it comprises end hypothesis on the furnace wall, an end is provided with the crossbeam of A font bracing frame,
Two lifting jacks, but their move left and right be connected on the said crossbeam;
One moves horizontally jack even, and it is fixed on the cross bar of said A font bracing frame.
Described glowing furnace, tempering furnace and normalizing furnace are arranged more changing device of burner down; Said crossbeam is an I-steel; But crossbeam is provided with the dolly of two move left and right; Dolly two scroll wheels on one side welds together, and said jack one end that moves horizontally hangs on the travelling car, and the other end hangs on the A font bracing frame.
A kind of glowing furnace, tempering furnace and normalizing furnace be row's burner replacing method down, and it comprises:
Step 1 is removed the Turbogrid plates on the stove platform, removes and is connected the pipeline on the burner, on the furnace wall, removes the connection spiral shell of burner to the support of said more changing device hypothesis;
Step 2 is suitably lifted and is moved horizontally jack, pulls out, and burner pulling out slowly, with crowbar sledge outward, pulls out at 2/3 o'clock the pull-up of lifting jack simultaneously, makes burner maintenance level, is pulled outwardly with moving horizontally jack again;
Step 3 after burner is pulled out body of heater, is walked with day handlebar replacing device and burner one lifting.Be put on the assigned address, pull down burner;
Step 4 is returned and is adorned new burner, is connected burner on the said more changing device; Hang the installation site together with day handlebar burner and changing device more, aligned position puts down burner with the lifting jack again; Moving dolly of sliding inward and burner after just putting; The back put in place with promoting jack adjusting height, to good screwed hole; Remove more changing device, connect bolt, connect all pipelines, build Turbogrid plates.
The dimensional requirement of the present invention according to the position of burner, structure and when installing done, and steel plate, I-steel, angle bar and pulley are material, is made with the method for welding etc.Change burner be with the step of end frame at stove on, an end A frame supports all on Turbogrid plates, promotes jack and fixes burner, the translation jack burner that pulls outward lifts by crane with overhead traveling crane one when burner is all pulled out.The new burner one lifting frame of coming is good in the replacing, pushes away burner inward.Install burner.Through changing the implementation result of burner several times; Use simple change the burner dolly after, change the number that the burner below the furnace roller uses and just can change what a burner in 1 hour with 3 people, former minimum 4 people 2 hours of wanting; And be easy to scald hand, by heat radiation burn face.Safe and reliable now, the workman can also avoid positive heat radiation.Change also light.
Description of drawings
Below, in conjunction with accompanying drawing the present invention is further described:
Fig. 1 is a working state schematic representation of the present invention.
Fig. 2 is said support and jack sketch map.
The specific embodiment
As shown in Figure 1, the present invention makes a kind of special replacement device, can guarantee this project of completion of highly effective and safe.A kind of glowing furnace, tempering furnace and normalizing furnace are arranged more changing device of burner down, and it comprises:
A support 1, it comprises that an end is erected on the furnace wall 2, an end is provided with the crossbeam of A font bracing frame,
Two lifting jacks 3, but their move left and right be connected on the said crossbeam;
One moves horizontally jack and connects 4, and it is fixed on the cross bar of said A font bracing frame.
Described glowing furnace, tempering furnace and normalizing furnace are arranged more changing device of burner down; Said crossbeam is an I-steel; But crossbeam is provided with the dolly 5 of two move left and right; Dolly two scroll wheels on one side is connected together, and said jack 4 one ends that move horizontally hang on the travelling car 5, and the other end hangs on the A font bracing frame.
Specific practice is:
1., remove the Turbogrid plates on the platform, remove and be connected the pipeline on the burner, frame is changing device better, the jack of on changing device more, registering.Remove the connection spiral shell of burner.
2., be connected the suitable pull-up of jack of burner tail end, the jack that pulls outward is pulled outwardly, burner pulling out slowly.With crowbar sledge outward, pull out at 2/3 o'clock simultaneously, make burner maintenance level the pull-up again of the jack of the inside.Be pulled outwardly with the jack that pulls outward again.
3., pull out body of heater after, change device with day handlebar and lift by crane with burner one.Be put on the assigned address, pull down burner.
4., return and to adorn new burner, be connected burner more above the changing device.With day handlebar burner and more changing device hang together.The position is to good, and two jacks put down burner again.Moving dolly of sliding inward and burner after just putting.Shift the jack of the inside that comes loose when jack contacts with the furnace wall onto, push away inward again.The back put in place with outside jack adjusting height, to good screwed hole.
5., remove more changing device, connect bolt, connect all pipelines, build Turbogrid plates.
