Abstract
The utility model relates to a furnace nose, in particular to a furnace nose for an aluminum-zinc-silicon-plated annealing furnace. The utility model aims to solve the problems that zinc steam is quite easy to enter a furnace-nose cavity of the furnace nose for a traditional aluminum-zinc-silicon-plated annealing furnace, the zinc steam is condensed into zinc powder to fall onto a steel plate after entering the furnace-nose cavity, and the plate quality is influenced. The furnace nose comprises a furnace-nose shell, an outer heat-preserving lining sleeve, a plurality of heating plates, an installing sleeve and a hanger, wherein the installing sleeve is sleeved on the furnace-nose shell, the outer heat-preserving lining sleeve is sleeved on the installing sleeve, the heating plates are arranged on the outer wall of the installing sleeve, a refractory fiber-material layer is arranged between the outer heat-preserving lining sleeve and the installing sleeve, and the outer heat-preserving lining sleeve is installed on a furnace body through the hanger. The furnace nose is used for reducing the zinc steam entering an inner cavity of the furnace nose and preventing the zinc steam from being coagulated into the zinc powder.
Description
Technical field
The utility model relates to a kind of stove nose, is specifically related to a kind of aluminum-zinc alloy annealed silicon stove stove nose.
Background technology
In the continuous zinc coating production line; because the fusing point of zinc solution is 420 ℃; the hot galvanizing liquid temperature should be controlled at about 460 ℃; but temperature must be controlled at more than 600 ℃ in the aluminum-zinc alloy silicon production line; under high-temperature like this; the zinc liquid highly volatile that does not have oxide protective layer in the zinc pot; form zinc fume; existing annealing furnace is not provided with heating unit with the stove nasal cavity of stove nose; very easily being condensed into zinc powder after zinc fume enters drops at steel plate; influence steel plate and contact, thereby the plating leakage defective of formation pin hole shape influences board quality with the direct of plating bath solution; and existing annealing furnace is simple in structure with the stove nose; prevent the aspect though zinc condenses, poor effect, and zinc fume very easily enters the stove nasal cavity.
The utility model content
The utility model is in order to solve existing aluminum-zinc alloy annealed silicon stove stove nose, and zinc fume very easily enters the stove nasal cavity, is condensed into zinc powder after zinc fume enters and drops at steel plate, influences the problem of board quality, and then proposes a kind of aluminum-zinc alloy annealed silicon stove stove nose.
The utility model is to address the above problem the technical scheme of taking to be: the utility model comprises stove nose shell, outer insulation lining tube, a plurality of hot-plates, installing sleeve and suspender member, serve as reasons the down cone table of supreme flaring of described stove nose shell, described outer insulation lining tube is the cone table of the assembled flaring from the bottom to top of polylith steel plate, described installing sleeve is the cone table of the assembled flaring from the bottom to top of polylith steel plate, described installing sleeve is sleeved on the stove nose shell, described outer insulation lining jacket casing is contained on the installing sleeve, the polylith hot-plate is arranged on the outer wall of installing sleeve, between described outer insulation lining tube and the installing sleeve one deck refractory fibrous material layer is arranged, described outer insulation lining tube is installed on the body of heater by suspender member.
The beneficial effects of the utility model are: the utility model is well controlled stove nasal cavity temperature; protection gas purity; hydrogen purity and protection gas dew point have obtained better control; thereby improved the quality of product; reduce steel band and formed the plating leakage defective that drops and on steel plate, produce behind the zinc powder owing to zinc fume; and running cost is low; it is convenient to change; the cone table of supreme flaring because the utility model is served as reasons down; lower port is very narrow; zinc fume is difficult for entering, even there is zinc fume to enter the stove nasal cavity, hot-plate has guaranteed that stove nasal cavity temperature is higher than the zinc fume temperature; make zinc fume can not be condensed into zinc powder, steel plate can not produce the plating leakage defective.
