Abstract
The utility model relates to a furnace nose device, solving the problems of the conventional furnace nose that zinc residues in the furnace nose are mainly drawn out based on the siphon principle or by utilizing a power pump, the amount of drawn-out zinc residues is limited in fact, and the pump is easily out of work due to being blocked by the zinc residues during the actual use. The furnace nose device comprises a fixed section (20), a flexible section (24) and a movable section (25), wherein the fixed section is flexibly connected with the movable section through the flexible section; a hydraulic cylinder (23) is hinged with the fixed section (20) by a mounting pedestal (22) of the hydraulic cylinder (23); a push-pull end of the hydraulic cylinder is hinged with the movable section, and cantilevers (21) are arranged on two sides of the fixed end; the cantilevers are connected with trunnions (26) on two sides of the movable section; and a nozzle (27) for injecting nitrogen is formed on the inner wall of the movable section. The furnace nose device is applied to a cold-rolled hot galvanizing production line and is used for removing residues on the surface of a zinc pot.
Description
Technical field:
The utility model relates to a kind of stove nose device that the cold rolling hot dip galvanizing production line can be removed zinc pot face slag that is applied to, and belongs to technical field of metallurgical machinery.
Background technology:
Referring to Fig. 1, in existing Continuous Production Line of Galvanizing by Dipping, after annealing by annealing furnace 1 through the band steel 5 of cleaning surfaces in advance, enter in the zinc pot 3 that fills high temperature zinc solution 4 by the stove nose 2 that is connected with annealing furnace subsequently and carry out immersion plating, control again thickness and the quality of coating by the air knife 7 of zinc pot sinking roller 6 tops.But the zinc liquid 4 in normal hot dip process process in the stove nose 2 is because of high temperature and easy zinc gray and the zinc liquid level slag of producing of zinc-iron reaction, because the area of stove nose 2 interior zinc liquid levels is little, these float over, and the cadmia on the zinc liquid level is easy to adhere to thus process band steel 5 surfaces in the stove nose, causes being with steel 5 coating surfaces the cadmia defective to occur.The way that the pump of the main a kind of siphon principle of dependence of cadmia removing or employing power is extracted the cadmia in the stove nose out in the existing stove nose solves.Because stove nose inner face slag becomes block, limited space in the stove nose is the fluctuation that reduces zinc liquid liquid level in addition simultaneously, so the existing pumping hole footpath that these take out cadmia is less, the actual cadmia that can extract out is very limited, and pump is easy to be stopped up by cadmia and lost efficacy in actual use.
Retrieve the hot dip coating method that one kind of patent CN147999A can remove the interior zinc gray of stove nose and scum silica frost, the clearing device of zinc gray cadmia in the CN200820150769.1 pot galvanize unit stove nose, the applied environment that these two kinds of public technologies are related and the subject matter that will solve are similar to present technique, but these two kinds of described devices of public technology are structurally obviously different from the present technique existence, and there is above-mentioned defective in varying degrees in these two kinds of public technologies simultaneously.
The utility model content:
The purpose of this utility model is that the problem for above-mentioned existence provides a kind of stove nose device, online utilize the band steel initiatively to contact with cadmia and the cadmia band is come out of the stove in the nose, reduced the shortcoming of taking out pulp pump obstruction, zinc liquid liquid fluctuating, weak effect that the traditional method scarfing cinder causes, and the method can directly be taken stove nose inner face slag out of the zinc pot.
Above-mentioned purpose realizes by following technical scheme:
Stove nose device, comprise canned paragraph and compliant section and active segment, described canned paragraph and active segment flexibly connect by compliant section, hydro-cylinder is hinged by its mounting seat and described canned paragraph, push-and-pull end and the described active segment of described hydro-cylinder are hinged, the both sides of described inboardend are provided with cantilever, and described cantilever is mounted on the gudgeon of described active segment both sides, are provided with the nozzle of nitrogen-blow on the inwall of described active segment.
Described stove nose device, the below end of described active segment is provided with snub pulley and upper supporting roller.
Beneficial effect:
1. the utility model is by making stove nose active segment realize the rotary oscillation of above-below direction under the effect of hydro-cylinder, realize that the stove nose inserts the slightly gradually change at inclination angle in the zinc pot, under the effect of nozzle nitrogen-blow, the zinc liquid level slag in the stove nose blowed to simultaneously the upper and lower surface with steel, thereby realize that the band steel initiatively contacts with cadmia and with the cadmia band nose of coming out of the stove.Prior art is compared, the utility model utilizes online the band steel initiatively to contact with cadmia and the cadmia band is come out of the stove in the nose, reduced the shortcoming of taking out pulp pump obstruction, zinc liquid liquid fluctuating, weak effect that the traditional method scarfing cinder causes, and the method can directly be taken stove nose inner face slag out of the zinc pot.
2. the utility model is provided with the wire nozzle of nitrogen-blow at the up and down inwall of stove nose active segment, can rapidly the face slag in the stove nose be gathered the surface with steel when utilizing this device scarfing cinder.
3. the utility model end below stove nose active segment is provided with two carrying rollers, the unusual scratch of belt steel surface in the time of can avoiding utilizing this device scarfing cinder.
