Description
Technical field
The utility model belongs to steelmaking equipment technical field, and in particular to a kind of novel baking of tundish device.
Background technique
Tundish is a molten steel transition tank in STEELMAKING PRODUCTION line between ladle and conticaster, and in the mistake of smelting iron and steel
It needs to toast tundish in journey, carries out down a series of operation again after baking of tundish to predetermined temperature.Existing
In technology, traditional continuous casting production roaster often involves great expense, and complete equipment position is fixed, and handling are inconvenient；In meanwhile
Between the burner of packet roaster be generally single hole through-hole, the burner being arranged in this way makes the burning of combustion gas insufficient at work, energy
Source waste is larger, while tundish is difficult to be well controlled in baking process Flame, and is difficult to according to specific intermediate
Packet toasts situation to be compared accurate adjusting to the intake of combustion gas and combustion-supporting gas.
Application No. is the utility model patents of CN201720089963.2 to disclose a kind of improved continuous casting tundish baking
Roasting device burner, including be arranged on continuous casting production roaster and save two burners of a burner and section, in continuous casting production roaster
Section one, interstitial hole is set on two burners of section, periphery hole is uniformly arranged on the periphery on interstitial hole periphery, wherein intermediate
The diameter in hole is 150-280mm, and the diameter of periphery hole is 50-120mm.Its is simple and reasonable, reliable performance, by burner by
Single hole through-hole originally is changed to distributing aperture, and baking coal gas is burnt by distributing aperture, toasts even flame, cured effect
Preferably, tundish service life is improved.
Although the patent can make fuel gas buring more uniform, improve the cured effect of tundish, if will in
Between hole be passed through combustion gas, periphery hole is passed through combustion-supporting gas, will cause flame firepower in this way and excessively concentrates, so that tundish various pieces
Baking is uneven, causes to occur bursting in tundish refractory material use process, fall off, influences the safety of continuous casting tundish
It uses；If periphery hole is passed through combustion gas, interstitial hole is passed through combustion-supporting gas, and it is uneven to will lead to combustion gas mixing in this way, leads to energy
Source waste.In addition, the cover board there are through-hole can be placed when toasting to tundish, on tundish, then burner is aligned
Through-hole is put down, and then carries out baking effect.In baking, because more closed, the specific baking situation of burner is difficult to obtain very
Good observation, in addition tundish internal temperature rises, and pressure also will increase, and is easy to happen and bursts equal accident.
Utility model content
The purpose of this utility model is that: baking of tundish device fuel gas buring is insufficient in the prior art for solution, tundish
Baking firepower concentration the problems such as be easy to causeing security risk, provide that a kind of combustion gas mixing is more abundant, and baking of tundish effect is more
Good novel baking of tundish device.
The technical solution adopted in the utility model is as follows:
A kind of novel baking of tundish device, including fuel gas conduit, combustion-supporting tracheae and burner, burner include multiple interstitial holes
And multiple periphery holes, periphery hole are separated by multiple first partitions, interstitial hole is connected to fuel gas conduit, and periphery hole and combustion-supporting tracheae connect
It is logical.
Wherein, interstitial hole includes being set to the first interstitial hole of center and being evenly distributed on around the first interstitial hole
The second interstitial hole, the first interstitial hole aperture be greater than the second interstitial hole aperture.
Wherein, first partition is arranged in parallel with burner surface.
Wherein, first partition is obliquely installed relative to burner, and first partition includes being inclined at fuel gas conduit outer tube wall
Intra vane and the outer leafs being connected with intra vane, outer leafs direction of twist are identical as intra vane inclined direction.
Wherein, it is additionally provided with outer housing, fuel gas conduit, combustion-supporting duct portion are set in outer housing, and outer housing is connected with lid
The upper cover plate of body, lid is connected with outer housing, and burner is set to outside the lower cover of lid.
Wherein, connected between upper cover plate and lower cover by multiple second partitions, between two neighboring second partition there are
Gap.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
1, in the utility model, by the way that multiple interstitial holes are arranged, combustion gas is dispersed, the mixed of combustion gas is further improved
It is right, so that burning is more abundant；Another aspect multiple groups interstitial hole is dispersed flame firepower when burning, and avoids fire
Power concentration damages tundish.The multiple periphery holes being arranged avoid combustion-supporting gas and form complete package work to combustion gas
With so that the combustion gas in centre is difficult to be mixed and burnt well, setting in this way makes the burning of combustion gas more later
Sufficiently, the service efficiency of combustion gas is improved；Regulate and control entirely through the situation that is passed through to combustion gas and combustion-supporting gas, just can
Situations such as baking temperature of roaster, is controlled well.
2, in the utility model, by opening up among first of the aperture in centre slightly larger than the second interstitial hole
Hole, the first interstitial hole play the role of a guiding to whole when being passed through combustion gas, surrounding uniform ring around the second interstitial hole institute
The combustion gas of pass-out follows the combustion gas of the first interstitial hole institute pass-out toward going out in vertical direction, enhances flame emission direction in this way
Stability shortens the time that relevant temperature is promoted to tundish.
3, in the utility model, by being arranged parallel to the first partition on burner surface, combustion-supporting gas is shunted, is kept away
Having exempted from the fully wrapped around combustion gas of combustion-supporting gas makes the combustion gas mixing degree in centre lower, to preferably improve combustion gas
Efficiency of combustion.
4, in the utility model, inclination, outer leafs setting distortion, so that combustion-supporting gas is arranged in the intra vane of first partition
The air-flow of rotation is formed when passing through burner；On the other hand, the setting of outer leafs direction of twist is identical as intra vane inclined direction, this
Sample can make combustion-supporting gas spiral inwardly to rotate, and combustion-supporting gas increases during toward burner axis direction helical rotation
The mixing of combustion-supporting gas and combustion gas further improves the utilization of combustion gas so that the fuel gas buring of interstitial hole pass-out is more abundant
Efficiency.
5, in the utility model, in the use process of roaster, the lower cover of lid is integrally carried out outer housing centainly
Supporting role, while lower cover being arranged using the very outstanding material of fire resistance, so that whole service life obtains
Very big extension；It is cheap in addition, the utility model overall structure is simple and practical, occupy little space, be easily installed and
Disassembly, conveniently moving, avoiding traditional baking of tundish device and tundish must being moved to fixed corresponding position just can be carried out very
Good baking effect, and only need to move roaster in the utility model and be just able to achieve to corresponding position and tundish is toasted,
Cost is saved.
6, in the utility model, by there are certain gaps between upper cover plate and lower cover, in this way convenient for observation in centre
Baking situation when packet baking adjusts and then the flame conditions to come up to rebound judge and is passed through combustion gas and combustion-supporting gas
Amount；On the other hand, the gap of setting facilitates the reduction of tundish internal pressure in baking, when avoiding baking of tundish
Internal pressure excessive situations such as exploding.
