Abstract
The utility model relates to a connecting structure for sealing an annealing heating furnace and a molten hot galvanizing pot on a continuous hot galvanizing production line, in particular to a novel furnace nose structure for a continuous hot galvanizing steel strip. The novel furnace nose structure is characterized in that a heating device is arranged on the outer side of a furnace nose liner, and a heat insulating material is coated outside the heating device. The furnace nose liner is made of a molten-zinc corrosion resistant metallic material or fireproof material. The heating device can be arranged around or on one side of the furnace nose liner. Compared with the prior art, the novel furnace nose structure has the advantages that on the basis of the conventional rectangular or irregular furnace nose structure, a heating and heat-insulating device is arranged on the furnace nose structure, so that the furnace nose structure has enough temperature to inhibit saturated zinc vapor from being condensed into zinc powder, and then the product quality is effectively improved.
Description
Technical field
The utility model relates to the syndeton of sealing between Annealing furnace and the melting heat galvanizing kettle on the Continuous Hot Dip Galvanizing Line, and the steel band that is heated to certain temperature with its assurance gets into zinc pot and don't oxidized device smoothly.
Background technology
To before getting into fused zinc liquid, be heated to certain temperature by the steel band of pot galvanize, and need be controlled at approximately about 460 ℃ when getting into zinc liquid, and therefore will have an airtight device to be connected between process furnace and the zinc pot, not oxidized to guarantee the steel band that therefrom passes through.Our custom be referred to as " stove nose ".Conventional stove nose, except two ends connect process furnace and zinc pot, middle through outside the steel band, other side all seals, and can't open, to guarantee that shielding gas is not revealed in the stove.Because the inner zinc liquid level of stove nose constantly produces zinc fume, is condensed into zinc powder in stove nasal cavity inside, hangs over the nasal cavity inner surface.Zinc powder is fallen surface of steel plate, must influence plate surface quality.
Summary of the invention
The purpose of the utility model is to provide a kind of continuous hot galvanizing steel band with novel stove nose structure; This structure is on traditional rectangular or special-shaped stove nose architecture basics; Increase heating and attemperator; Make it have sufficient temp to suppress saturated zinc vapor condensation and become zinc powder, thereby can effectively improve the quality of products.
For realizing above-mentioned purpose, the present invention realizes through following technical scheme:
A kind of continuous hot galvanizing steel band is characterized in that with novel stove nose structure, is provided with heating unit in the outside of stove nose inner bag, is covered with lagging material in the heating unit external packets.
Described stove nose inner bag adopts the metallic substance or the refractory materials of liquid zinc corrosion resistant to process.
Described heating unit, can be arranged on stove nose inner bag around or a side.
Compared with prior art, the beneficial effect of the utility model is:
This structure increases heating and attemperator on traditional rectangular or special-shaped stove nose architecture basics, make it have sufficient temp to suppress saturated zinc vapor condensation and become zinc powder, thereby can effectively improve the quality of products.

Embodiment
Below in conjunction with accompanying drawing the technology contents of the utility model is done further explain.
See Fig. 1, a kind of continuous hot galvanizing steel band is provided with heating unit with novel stove nose structure in the outside of stove nose inner bag, is covered with lagging material in the heating unit external packets.Described stove nose inner bag adopts the metallic substance or the refractory materials of liquid zinc corrosion resistant to process.Described heating unit can be arranged on stove nose inner bag around or a side.Heating unit can adopt resistance heating element or other arbitrary type of heating.
When the pot galvanize steel band normally moved, stove nose inner and upper had a large amount of zinc fumes and produces, and runs into stove nose sidewall, before this structure produces, can be condensed into zinc powder; The utility model heating can avoid saturated zinc vapor condensation to become zinc powder with the setting of insulation construction.This device Heating temperature is controlled, and TR is generally between 100-800 ℃.
