Description
Technical field
The present invention relates to hot dip galvanized zinc alloy technique and apparatus field used thereof, be specially a kind of stove nose for pot galvanize many mouthfuls of deslagginves and using method thereof.
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, zinc liquid, also (Zn and Al that the zinc liquid in zinc pot is respectively 97% and about 3% by mass ratio forms to produce cadmia after zinc liquid and band steel react, the Fe ion on a top is brought again after entering zinc pot with steel, Zn, the metal ion such as Al and Fe jointly react and generate the compound and cadmia that mass ratio Zn:Fe:Al is 4:7:9, because the Al content that density is less is higher in cadmia, therefore density is less than the density of zinc liquid), these zinc grays, the density ratio zinc liquid of cadmia is little, zinc liquid surface can be floated up to.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.
Have at present to adopt and bottom stove nose, mark deslagging funnel and scum pipe is set to discharge the structure of dregs, but, due to the viscosity ratio of zinc liquid, comparatively large fluidity is poor, in order to shorten scum pipe length, a scum pipe can only be arranged on the end of deslagging funnel, cause the zinc liquid pump drainage deleterious away from scum pipe side, especially width is greater than to the stove nose of 2.5 meters, the stove nose of a scum pipe is difficult to reach satisfied deslagging effect.
Summary of the invention
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 invention discloses a kind of stove nose for pot galvanize many mouthfuls of deslagginves and using method thereof.
The present invention reaches goal of the invention by following technical solution:
For a stove nose for pot galvanize many mouthfuls of deslagginves, comprise stove nose body, stove nose body is located at the exit end of annealing furnace chute, it is characterized in that: also comprise dividing plate, base plate, scum pipe, the suction pump of zinc liquid and zinc liquid vent pipe,
Lower part of stove nose chamber body is provided with dividing plate, two sides of dividing plate are separately fixed on the inner side-wall of stove nose body, lower part of stove nose chamber body is separated into two intervals by dividing plate, an interval in described two intervals is as deslagging funnel, the open top of deslagging funnel, the bottom of deslagging funnel is closed with base plate, and on base plate, compartment of terrain is provided with at least two scum pipes, and the inner chamber of scum pipe and deslagging funnel is through;
The exit end of each scum pipe respectively establishes the suction pump of a zinc liquid, and the liquid pumping hole of zinc liquid suction pump is located at the exit end of scum pipe, and the leakage fluid dram of every platform zinc liquid suction pump connects a zinc liquid vent pipe, and the exit end of zinc liquid vent pipe is located at stove nose, and this is external.
The described stove nose for pot galvanize many mouthfuls of deslagginves, it is characterized in that: lower part of stove nose chamber body is separated into unequal two intervals of section area by dividing plate, the ratio of described two interval section area is 1.5 ~ 5, and the less interval of the section area in described two intervals is as deslagging funnel.
The using method of the described stove nose for pot galvanize many mouthfuls of deslagginves, is characterized in that: implement successively as follows:
Under the bottom of stove nose body being inserted the zinc liquid level of zinc pot, due to the principle of communicating vessels, the zinc liquid level comprising zinc liquid level in deslagging funnel and zinc pot in stove nose body flushes, the top of dividing plate is made to be positioned at the below of deslagging funnel zinc liquid level, under making the exit end of zinc liquid vent pipe be located at this external zinc pot zinc liquid level of stove nose;
Open the suction pump of zinc liquid, zinc liquid in deslagging funnel is evacuated in this external zinc pot of stove nose by the suction pump of zinc liquid, zinc gray, cadmia to take out of in deslagging funnel to this external zinc pot of stove nose and to be skimmed after zinc liquid level, are made the zinc liquid level in deslagging funnel reduce by zinc liquid simultaneously; Like this in stove nose body, zinc liquid level outside deslagging funnel is higher than the zinc liquid level in deslagging funnel, zinc liquid flows in deslagging funnel from the top on stove nose body internal partition top, and this external zinc liquid of stove nose is then flowed in stove nose body by the bottom of stove nose body, thus completes and once take out the circulation of zinc liquid; The suction pump of zinc liquid continues suction and makes to take out zinc liquid circulation continuous and carry out, the intrinsic zinc gray of stove nose, cadmia by continue take out of after skimmed.
Zinc gray, the mobility of cadmia is poor, general abstracting method can only extract most zinc liquid, and be difficult to zinc gray and cadmia to be released, and the present invention is by the lasting suction function of zinc liquid suction pump, the liquid level difference of zinc liquid level is created between inside and outside the intrinsic deslagging funnel of stove nose, making to take out while zinc liquid circulation continuous carries out, also make the flowing kinetic energy of zinc liquid larger by potential energy and dynamic transformation of energy, mobility is stronger, carry zinc gray, the ability of cadmia is also stronger, under the continuous service taking out the circulation of zinc liquid, zinc gray, cadmia is taken out of in the zinc pot of stove nose body exterior by zinc liquid from stove nose body interior more up hill and dale, by zinc gray after floating to zinc liquid level, cadmia skims, thus guarantee strip surface quality.
Stove nose body inserts in zinc pot by the present invention, the zinc liquid in zinc pot is utilized to implement sealing to annealing furnace chute, utilize the intrinsic partial section of stove nose as deslagging funnel, on deslagging funnel, be provided with at least two scum pipes simultaneously, every root scum pipe connects the suction pump of zinc liquid respectively, deslagging excellent result, effectively the dregs such as zinc gray, cadmia floating over zinc liquid upper surface in stove nose body can be discharged completely, especially the stove nose body effect of 2.5 meters is greater than for width even more ideal, can guarantees to stably produce high-quality galvanized sheet.
The invention has the beneficial effects as follows: deslagging is effective, galvanizing quality is high, easy to operate.
