Description
Technical field
The utility model relates to hot dip galvanized zinc alloy technique and apparatus field used thereof, is specially a kind of stove nose blowing slagging structure for pot galvanize band.
Background technology
Iron and steel answers the most a kind of metal with the most use at present in the world; but ferrous materials is easily corroded under the acting in conjunction of empty G&W; in order to reduce the corrosion of ferrous materials; comparatively general method is armor coated on steel surface at present; because zinc has good erosion resistance in an atmosphere; simultaneously price also metal inexpensively, make protective layer cost by zinc layers lower, therefore pot galvanize becomes most widely used metal rust preventing method.
Generally all will through stamping procedure when modern galvanized sheet is produced; very high requirement is proposed to the ductility of band steel; so Continuous Hot Dip Galvanizing band steel all wants annealed technique before entering into zinc pot; not oxidized at high-temperature condition for ensureing band steel in annealing furnace; general all pouring is protected by nitrogen, hydrogen mixed gas; stove nose is the key equipment that annealing furnace is deep in zinc pot, plays the effect to annealing furnace sealing.Band steel from annealing furnace out after directly go deep into completing zincincation in zinc pot.Temperatures as high in zinc pot 450 DEG C, at this temperature, zinc liquid can form zinc gray by evaporation and condensation in stove nose, also (in zinc pot, zinc liquid is made up of the Zn of about 97% and the Al of about 3% to produce cadmia after zinc liquid and band steel react, enter into zinc pot with steel and can bring certain Fe ion, these meeting of Fe ion and Zn, Al ion generation chemical reaction, generate compound (numerical value in bracket is mass percent) the i.e. cadmia of Zn (20%)+Fe (35%)+Al (45%), these cadmias due to Al content higher, than zinc solution light specific gravity, zinc liquid surface can be floated over always.Inner at stove nose, because zinc liquid is in the space of a relative closure, therefore, supernatant zinc gray, cadmia can adhere to belt steel surface, form zinc gray print, cadmia print.At present, present industrial expansion makes day by day to improve the surface quality requirements of galvanized sheet, galvanized sheet as automobile exterior panel requires that reaching naked eyes cannot tell defect, therefore zinc gray print, cadmia print and the defect such as impression, scuffing that causes thus can have a strong impact on the surface quality of band steel, are not suitable with the demand of modern industry.
In order to effectively discharge zinc gray in stove nose and cadmia, devising the stove nose of band slagging structure, comprising single deslagging pipe furnace nose, the stove nose of band both sides scum pipe, the stove nose etc. with four limit slagging structures.These stove noses are all with one or two scum pipe, scum pipe is welded to above stove nose deslagging funnel soleplate, the stove nose of this spline structure is applicable to liftable zinc pot, but be applied to the zinc pot just very large difficulty of horizontal shifting, because scum pipe blocks the movement of zinc pot, move zinc pot and must first dismantle stove nose, and the dismounting of stove nose once needs 8 to 12 hours consuming time, so cause the movement of zinc pot must stop production for a long time, adds additional again a large amount of labor workload, but also there is the problem that zinc gray cadmia is easily gathered in stove nose minor face two side areas.
Utility model content
In order to overcome the defect of prior art, providing the pot galvanize utility appliance that a kind of deslagging is effective, galvanizing quality is high, easy to operate, the utility model discloses a kind of stove nose blowing slagging structure for pot galvanize band.
The utility model reaches goal of the invention by following technical solution:
A kind of stove nose blowing slagging structure for pot galvanize band, comprise zinc pot, annealing furnace chute and stove nose, zinc liquid is held in zinc pot, annealing furnace chute and stove nose are all located at the top of zinc pot, the top joint flange of stove nose is removably fixed on the bottom of annealing furnace chute, the bottom of stove nose stretches into below the zinc liquid liquid level in zinc pot obliquely, zinc liquid in zinc pot injects the zinc liquid being formed in stove nose and be positioned at stove nose, it is characterized in that: also comprise and take out zinc liquid pump base, take out zinc liquid pump, suction tube, vent pipe, blow zinc liquid pump base, blow zinc liquid pump and blow liquid pipe
Two opposites on outer side bottom stove nose symmetrically and with bolt removably fix one take out zinc liquid pump base and one blow zinc liquid pump base;
The pump housing bolt taking out zinc liquid pump is removably fixed on to be taken out on zinc liquid pump base, the aspiration end of suction tube is located on the liquid level of interior zinc liquid, the drain side of suction tube connects the liquid pumping side of taking out zinc liquid pump, the drain side of taking out zinc liquid pump removably connects the liquid feeding end of vent pipe with flange, under the outlet end of vent pipe is located at the liquid level of zinc liquid in zinc pot;
The pump housing bolt blowing zinc liquid pump is removably fixed on and blows on zinc liquid pump base, and the outlet of blowing liquid pipe is located on the liquid level of interior zinc liquid, the import of blowing liquid pipe connect blow zinc liquid pump blow liquid mouth, under the fluid inlet of zinc liquid pump is located at the liquid level of zinc liquid in zinc pot;
Suction tube and blow two opposites place that stove nose medial surface is located at symmetrically by liquid pipe.
The described stove nose blowing slagging structure for pot galvanize band, is characterized in that:
The aspiration end of suction tube is splay end mouth, and the liquid level of suction tube aspiration end center in the vertical direction and interior zinc liquid flushes; The liquid level of the end face center in the vertical direction and interior zinc liquid of blowing the outlet of liquid pipe flushes.
The described using method of blowing the stove nose of slagging structure for pot galvanize band, is characterized in that: implement successively as follows:
Arrange: below the zinc liquid liquid level of the bottom of stove nose insertion zinc pot, the zinc liquid in zinc pot injects the zinc liquid being formed in stove nose and be positioned at stove nose;
Blow liquid: open and take out zinc liquid pump and blow zinc liquid pump;
Slagging-off: blow zinc liquid pump and interior zinc liquid is blowed to opposite side from the side of stove nose inside, takes out zinc liquid pump and is discharged to stove nose outside by blowing over the zinc gray cadmia extraction floating over interior zinc liquid surface come.
The utility model can up to long term operation in the zinc pot of 450 DEG C, can very effective the zinc liquid pump drainage of upper surface in stove nose be come out of the stove outside nose, because scum pipe of the present utility model, zinc pump and zinc pump mounting seat can dismounting separately, so, can dismantle separately before zinc pot moves, such zinc pot moves just does not need dismounting stove nose, dismounting scum pipe, zinc pump and base only need 1 to 2 hour, so each zinc pot moves the time just decreasing a large amount of dismounting stove noses, also greatly reduces labor workload:
The utility model is provided with two zinc liquid pumps, the zinc liquid level position of zinc liquid from stove nose minor face side blows side to other one by one of them zinc liquid pump, another zinc liquid pump is responsible for extracting out blowing over the zinc gray cadmia floating over zinc liquid surface come and being discharged to stove nose outside, so just can the problem of very effective solution stove nose inner zinc gray cadmia localized clusters, make stove nose inside not have zinc gray cadmia to assemble dead angle.In order to obtain better pump drainage effect, the structure that aspiration end adopts and zinc liquid level is at 45 ° of suction tube, can not affect pump drainage zinc liquid effect like this when zinc liquid level has slight fluctuations.
The beneficial effects of the utility model are: deslagging is effective, and galvanizing quality is high, easy to operate, save manpower and man-hour.
