Abstract
The utility model discloses a zinc terminal sealing system. Nitrogen and hydrogen mixed shielding gas is heated by a heating box and then is led to a gas inlet of a zinc terminal; a glow heater is arranged in the zinc terminal, and the leaked oxygen and hydrogen in the led shielding gas can be heated by the glow heater and mutually react, so that the occurrence of explosion caused by the overhigh oxygen concentration inside the zinc terminal is prevented. Before the shielding gas is led to the zinc terminal, the shielding gas is heated by the heating box; when the temperature of the shielding gas is 50 DEG C higher than that of strip steel, heating is stopped; the strip steel cannot be cooled after the shielding gas is led, the leaked oxygen and the hydrogen in the led shielding gas are heated by the glow heater and mutually react, and the occurrence of explosion caused by the overhigh oxygen concentration inside the zinc terminal is prevented.
Description
Technical field
The utility model relates to a kind of tightness system, especially a kind of zinc nose tightness system.
Background technology
Zinc nose is a seal channel that connects hot bridle rolls chamber and zinc pot, with steel, completes and by this passage, enters zinc pot after thermal treatment and complete surperficial galvanizing process.Existing zinc nose is generally the passage of the rectangular parallelepiped being formed by Plate Welding, in order to guarantee that sealing prevents that outside air admission passage from making to be with steel oxidation, is provided with seal protection gas and passes into hole to maintain in passage as malleation on passage.To the temperature with steel, need to control within the specific limits when with the reacting of steel and zinc liquid in zinc pot, but the temperature that the shielding gas of a large amount of normal temperature can cooling zone steel after passing into makes galvanizing process be not easy to control, and affects surface quality.
Summary of the invention
Main purpose of the present utility model is to provide a kind of zinc nose tightness system, to the protection gas heating passing into, and temperature that can cooling zone steel after therefore passing into, and the oxygen reaction of zinc nose inside can be fallen.
In order to achieve the above object; the utility model adopts following technical scheme: a kind of zinc nose tightness system; nitrogen hydrogen hybrid protection gas passes into the gas inlet on zinc nose after adopting heating container heating again; in zinc nose, be provided with glow heater; glow heater is the hydrogen reacting by heating in the oxygen bleeding and the shielding gas that passes into, to prevent that the inner oxygen concentration of zinc nose is too high, blasts.
As further preferably, in described heating container, be furnished with resistance wire.
As further preferred, described glow heater is arranged on zinc nose wall, and its heater strip stretches into zinc nose inside.
The beneficial effects of the utility model are: the utility model is before protection gas passes into zinc nose; adopt heating container will protect gas heating; be heated to than the high 50 degree left and right of belt steel temperature; therefore temperature that can cooling zone steel after passing into; and glow heater is the hydrogen reacting by heating in the oxygen bleeding and the shielding gas that passes into, to prevent that the inner oxygen concentration of zinc nose is too high, blast.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram.
Being described as follows of mark in accompanying drawing: 1-heating container, 2-gas inlet, 3-zinc nose, 4-glow heater, 5-gas pipeline, 6-band steel, the hot bridle rolls of 7-chamber, 8-zinc pot, 9-flange connections.
Embodiment
Realization, functional characteristics and the beneficial effect of the utility model object, be described further below in conjunction with specific embodiment and accompanying drawing.
Below in conjunction with the drawings and specific embodiments, technical scheme described in the utility model is described in further detail, so that those skilled in the art can better understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.
As shown in Figure 1; the zinc nose tightness system of the utility model embodiment; wherein nitrogen hydrogen hybrid protection gas passes into the gas inlet 2 on zinc nose after adopting heating container 1 heating again; in zinc nose 3, be provided with glow heater 4; glow heater 4 is the hydrogen reacting by heating in the oxygen bleeding and the shielding gas that passes into, to prevent that the inner oxygen concentration of zinc nose is too high, blasts.
In heating container 1, be furnished with resistance wire.
In prior art, zinc nose flange connections 9 is conventionally poorly sealed, so must adopt air seal protection.
Claims (3)
1. a zinc nose tightness system, is characterized in that: after nitrogen hydrogen hybrid protection gas passes into heating container, be connected to the gas inlet on zinc nose again, in zinc nose, be provided with glow heater.
2. zinc nose tightness system according to claim 1, is characterized in that: in described heating container, be furnished with resistance wire.
3. zinc nose tightness system according to claim 1, is characterized in that: described glow heater is arranged on zinc nose wall, and its heater strip stretches into zinc nose inside.
