Description

A kind of slab CC tundish baking system
Technical field
The utility model relates to a kind of for toasting the device of slab CC tundish, belongs to metal casting technical field.
Background technology
Steel plant continuous casting tundish adopts coal gas to toast more; Fig. 1 is a kind of conventional baking of tundish device; mainly formed by burner, PLASTIC LAMINATED (being made by the corrosion resistant plate that 3mm is thick), middle bag clad, gas piping and air duct; PLASTIC LAMINATED is welded on roaster bottom, is mainly used in roaster to protect.Find in actual use, gap between burner and middle bag clad can constantly increase, the larger gap of general also existence between PLASTIC LAMINATED and middle bag clad, when baking flame can from PLASTIC LAMINATED and gap between bag clad leak, not only cause the waste of coal gas, but also can make PLASTIC LAMINATED temperature distortion, cause the raising of roaster operation and maintenance cost.In addition, in order to save coal gas, in middle water-coating port general using, wrap the high-temp waste gas producing in bake process and toast, but the high-temp waste gas that injection is discharged can pollute mouth of a river external environment condition, cause huge harm to workman's health.
Utility model content
The purpose of this utility model is the drawback for prior art, and a kind of slab CC tundish baking system is provided, and to reduce the operation and maintenance cost of roaster, reduces environmental pollution.
Problem described in the utility model realizes with following technical proposals:
A kind of slab CC tundish baking system, formation comprises middle bag clad, burner, PLASTIC LAMINATED and suspension rod, described middle bag clad and PLASTIC LAMINATED cover successively on tundish, described burner is connected with the source of the gas of coal gas and air with air duct by gas piping, its flame ejection end successively through hole on PLASTIC LAMINATED and middle bag clad is inserted in tundish, on described PLASTIC LAMINATED, be provided with up-thin-low-thick shoulder hole, described suspension rod penetrate in the shoulder hole of PLASTIC LAMINATED and with PLASTIC LAMINATED matched in clearance, its lower end is provided with anti-disk stripping, and upper end is fixedly connected with air duct.
Above-mentioned slab CC tundish baking system, in formation, also comprise mouth of a river apparatus for baking, described mouth of a river apparatus for baking comprises furnace shell, injecting tube and draught fan, described furnace shell is sleeved on the outside of middle water-coating port, the inlet end of described injecting tube is connected with the air outlet of draught fan, exhaust end is communicated with the air duct of burner through airduct, and two air entries on its sidewall connect respectively the lower openings of atmosphere and furnace shell.
Above-mentioned slab CC tundish baking system, the surface of described PLASTIC LAMINATED scribbles refractory material.
Above-mentioned slab CC tundish baking system, described suspension rod at least arranges three, and they are evenly arranged on PLASTIC LAMINATED.
PLASTIC LAMINATED of the present utility model can slide up and down along suspension rod, under Action of Gravity Field, this PLASTIC LAMINATED can fit tightly with middle bag clad, roaster is being protected simultaneously, also improve the sealing of tundish, thereby effectively prevent a large amount of wastes of the energy, reduced the operation and maintenance cost of roaster, reduced environmental pollution.
The utility model utilizes in high-temp waste gas baking water-coating port and final waste gas is introduced to air duct and reuses, and has also improved worker's operating environment in saving coal gas, has eliminated the danger of worker's gas poisoning.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the structural representation of traditional baking of tundish system;
Fig. 2 is structural representation of the present utility model.
In figure, each label is: 1, burner, 2, PLASTIC LAMINATED, 3, middle bag clad, 4, middle water-coating port, 5, tundish, 6, Electrohydraulic push rod, 7, pull bar, 8, gas piping, 9, injecting tube, 10, air duct, 11, suspension rod, 12, flame, 13, furnace shell, 14, draught fan, 15, compressed air inlet.
The specific embodiment
Design philosophy:
(1) first can meet the requirement of baking of tundish temperature homogeneity.
(2) secondly can reduce baking time, the loss of heat, improves the thermal efficiency.
(3) be easy to change on the basis of existing roaster, meet environment protection requirement, guarantee after transformation environmental sound.
Based on above design philosophy, the utility model improves the structure of roaster PLASTIC LAMINATED, adopts heat resistant fireproof material to replace original steel plate, and by changing its fixed form, the sealing while increasing baking of tundish, improves the thermal efficiency.When the mouth of a river baking, outer row's high-temp waste gas is recycled simultaneously, in increasing the thermal efficiency, improves environment, improves air quality, reaches the object of energy-conserving and environment-protective.
Referring to Fig. 2, the utility model comprises burner 1, PLASTIC LAMINATED 2, middle bag clad 3, gas piping 8, injecting tube 9, air duct 10, suspension rod 11, furnace shell 13, draught fan 14.
PLASTIC LAMINATED 2 not only protects roaster, also plays the effect of tundish being carried out to fire proof seal, makes up the not tight defect of middle bag clad.The outside of PLASTIC LAMINATED 2 scribbles refractory material, for weight reduction as far as possible, the THICKNESS CONTROL of PLASTIC LAMINATED 2, at 100mm, is considered to the fixing reliability of bulk strength and PLASTIC LAMINATED 2, suspension rod 11 is done closelyer as far as possible, guarantee that in use PLASTIC LAMINATED 2 does not come off.In order to make PLASTIC LAMINATED and to fit tightly with middle bag clad, change the fixed form of PLASTIC LAMINATED 2 into flexible connection by original welding, in the time that baking arm drops on tundish, PLASTIC LAMINATED can be fitted with middle bag clad automatically, effectively stops flame to leak.
The baking of middle water-coating port, the high-temperature gas centering water-coating port that Bao Baonei in the extraction of suction method is penetrated in employing toasts, the gas handling system repetitive cycling that the high-temp waste gas of extracting out during by middle water-coating port baking is introduced baking arm by pipeline is utilized, so just improved the temperature of mixing air, indirectly improve efficiency of combustion, and make the whole baking system of tundish there is no extra outer waste air, improved site environment.When high-temp waste gas collects to air duct, adopt and penetrate absorbing method mixing, solved the problem of two kinds of gas pressure difference.
The utility model is simple in structure, does not have too large input, can effect ideal, can reduce gas consumption, reduces manufacturing cost, improves operating environment.
It should be noted last that: although above-described embodiment has been described in detail this technology, those of ordinary skill in the art is to be understood that: still can modify or be equal to replacement this technology, and do not depart from any modification or partial replacement of the spirit and scope of this technology, all should be encompassed in the middle of the claim scope of this technology.
