Abstract
The utility model discloses a kind of strip zinc grays used for hot dip galvanizing to obstruct dust-extraction unit, including stove nose, the stove nose is inclined at the top of zinc pot, it is characterized in that, air knife dust pelletizing system is provided on the stove nose, the air knife dust pelletizing system includes nitrogen interface and two groups of high pressure air knives, and two groups of high pressure air knives are arranged intranasal in stove one on the other, the nitrogen interface is connected with high pressure air knife, and there are two downward opening air knives to export for every group of high pressure air knife.The zinc gray of belt steel surface adherency is being removed to belt steel surface blown inert gas nitrogen simultaneously, additionally it is possible to which effectively barrier zinc gray continues, toward stove nose upper direction, to efficiently solve the problems, such as the defect caused by zinc gray is to product in strip both sides using high pressure air knife.
Description
Technical field
The utility model is related to hot galvanizing line production equipment, specifically a kind of strip zinc gray barrier dedusting dress used for hot dip galvanizing
It sets.
Background technology
In hot galvanizing line production, when the zinc liquid in zinc pot is heated to 475 DEG C or more, the temperature that strip enters zinc pot is
460 DEG C or so, it is intranasal to enter stove when strip goes out zinc pot with micro dust zinc, rise to after certain altitude due to in stove nose
Displacement reaction occurs for moisture and the factor of micro oxygen generation oxidation reaction forms Zinc oxide particles, and here it is the zinc that we often say
Ash.Practical aborning zinc gray is the mixture of pure zinc, zinc oxide and some other impurity.
Zinc gray is suspended in the surface of zinc liquid in stove nose, when strip longtime running zinc gray can adhere to belt steel surface, according to zinc gray
It is different in the distribution of liquid level, zinc gray defect of different shapes can be generated in the different location of strip.Brought into the zinc of zinc pot by strip
Ash can also adhere to the surface of sinking roller, cause sinking roller roll marks.If zinc gray enters sinking roller, stabilizing roller, correct roller
The rotary resistance that three rollers are also resulted between axis and axle sleeve increases, and sinking roll marks has been further aggravated, has seriously also resulted in sinking roller
It scratches and axle sleeve serious wear is even worn out.Zinc gray defect is the main bottleneck that current product quality improves.Due to zinc gray defect
Presence, prevent hot dip zinc product from meeting higher product requirement, to produce the product of great surface quality, zinc gray defect must
It need to thoroughly be solved.
Utility model content
To solve the above problems, the utility model provides a kind of strip zinc gray barrier dust-extraction unit used for hot dip galvanizing, it can be effective
Solve zinc gray defect, Improving The Quality of Products.
The technical solution adopted in the utility model is：
A kind of strip zinc gray barrier dust-extraction unit used for hot dip galvanizing, including stove nose, the stove nose are inclined at the upper of zinc pot
Side, is provided with air knife dust pelletizing system on the stove nose, and the air knife dust pelletizing system includes nitrogen interface and two groups of high pressure air knives, and two
Group high pressure air knife is arranged intranasal in stove one on the other, and the nitrogen interface is connected with high pressure air knife, and every group of high pressure air knife has
Two downward opening air knife outlets.
Further, ash slot and fishing ash are disposed on the stove nose below the air knife dust pelletizing system from top to bottom
Hole.
The utility model has the beneficial effects that：Utilize high pressure air knife to belt steel surface blown inert gas nitrogen in strip both sides
Gas is removing the zinc gray of belt steel surface adherency simultaneously, additionally it is possible to which effectively barrier zinc gray continues, toward stove nose upper direction, effectively to solve
The problem of defect caused by zinc gray is to product of having determined.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Wherein：1, stove nose, 2, zinc pot, 3, nitrogen interface, 4, high pressure air knife, 5, air knife outlet, 6, ash slot, 7, fishing ash
Hole, 8, strip.
Specific implementation mode
In order to deepen the understanding to the utility model, the utility model is made below in conjunction with embodiment and attached drawing further
It is described in detail, which is only used for explaining the utility model, does not constitute the restriction to the scope of protection of the utility model.
As shown in Figure 1, a kind of strip zinc gray used for hot dip galvanizing obstructs dust-extraction unit, including stove nose 1, stove nose 1 tilts 45° angle and sets
It sets in the top of zinc pot 2, air knife dust pelletizing system is provided on the centre position of stove nose 1, air knife dust pelletizing system includes that nitrogen connects
Mouth 3 and two groups of high pressure air knives 4, two groups of high pressure air knives 4 are arranged one on the other in stove nose 1, nitrogen interface 3 and 4 phase of high pressure air knife
Connection, there are two downward opening air knives to export 5 for every group of high pressure air knife 4.
When production, strip 8 passes through stove nose, while strip 8 passes through high pressure air knife, and the air knife outlet 5 of every group of high pressure air knife is
The both sides of strip are distributed in, by being filled with high pressure nitrogen in nitrogen interface 3, air knife outlet 5 is dried to belt steel surface, removed simultaneously
The zinc gray for going belt steel surface to be taken out of from zinc pot 2, while zinc gray continuation can be obstructed and up moved.And the zinc gray blown off falls on and connects
In ash-pit 6, after production, strip shuts down, by manually taking out the zinc gray in ash slot 6 from fishing ash hole 7.
Claims (2)
1. a kind of strip zinc gray used for hot dip galvanizing obstructs dust-extraction unit, including stove nose, the stove nose are inclined at the top of zinc pot,
It is characterized in that, being provided with air knife dust pelletizing system on the stove nose, the air knife dust pelletizing system includes that nitrogen interface and two groups are high
