Description
Technical field
The utility model relates to a kind of hot-galvanizing equipment, especially a kind of centrifugal zinc-extracting liquid slag removal device.
Background technology
Full-fledged along with modern pot galvanize technology, the quality of hot-dip galvanizing sheet steel is more and more near electrogalvanizing steel plate.Because hot-dip galvanizing sheet steel cheap for manufacturing cost, make and more and more use the field of electrogalvanizing steel plate then adopt hot-dip galvanizing sheet steel originally, for example: automobile, household electrical appliances, food etc.And the principal element of restriction hot-dip galvanizing sheet steel in the high-grade application field is surface quality.The hot galvanizing surface quality is subjected to the influence of the zinc pot technology of continuous hot galvanizing line to a great extent.Heat zinc coating plate in process of production, zinc liquid surface can constantly produce scum silica frost and zinc gray in the zinc pot, these scum silica frost and zinc gray can stick to and form surface imperfection on the steel plate, thereby have a strong impact on subsequent applications.Therefore the scum silica frost and the zinc gray that how to remove zinc pot liquid level are the keys of producing high-grade heat zinc coating plate.
As everyone knows, continuous hot galvanizing line is online reduced anneal, and that finishes that the steel plate of reduced anneal seals after leaving the annealing furnace cooling section enters the nitrogen cover, enters the zinc pot by the nitrogen cover that is full of nitrogen then, and the lower end of nitrogen cover is by zinc liquid sealing in the zinc pot.Therefore the zinc liquid level is divided into two zones, the regional zone that covers with the nitrogen cover that is filled nitrogen of exposed aerial liquid level.Exposed aerial zinc liquid level is easy to generate a kind of scum silica frost of mixing element, and it mainly consists of zinc oxide, aluminum oxide and Fe2Al5.In actual production, exposed aerial scum silica frost is generally taked artificial or machinery is fished for operation and removed.And the liquid level that is sealed in nitrogen cover inside also can produce scum silica frost, and it mainly forms part is that the ash that zinc liquid level evaporable zinc fume condenses into is called for short zinc gray.In actual production, can't directly fish for the scum silica frost on the inner zinc liquid level of nitrogen cover, this has just seriously restricted the surface quality of hot-dip galvanizing sheet steel.
For the high-grade heat zinc coating plate of continuous and stable production, often there are two kinds of physical constructions can realize extracting the inner zinc liquid of nitrogen cover surface scum at present.A kind of is that nitrogen blows belt, and another kind is a mechanical pump.Nitrogen blows a U type communicating pipe in the belt, the zinc liquid level nitrogen cover that the end opening of this communicating pipe is immersed in place, below slightly is used for taking out zinc, and the other end opening of communicating pipe outside the nitrogen cover zinc liquid level slightly above locate to be used for discharging zinc liquid, opening part outside the nitrogen cover inserts a nitrogen tube and also immerses zinc liquid.During device work, the nitrogen of pressure regulation is blown into the U type pipe at zinc outlet place, because nitrogen kinetic energy and buoyancy and viscid effect, zinc liquid is taken out of by nitrogen from zinc outlet endlessly, the other end in U type communicating pipe constantly replenishes zinc liquid simultaneously, cadmia and zinc gray that mobile zinc liquid has also driven zinc liquid surface enter U type pipe, thereby are discharged from the nitrogen cover.The advantage that this nitrogen blows belting is that cost is low, and equipment is simple.Its shortcoming is: the zinc flow quantity is little, and the efficient of taking the cadmia zinc gray out of is low, and the zinc liquid that low temperature nitrogen blows out easily becomes slag and causes the zinc consumption to increase, and nitrogen pressure causes zinc liquid to splash more greatly, has hidden danger; The device that utilizes mechanical pump to extract cadmia zinc gray in the nitrogen cover comprises three parts: take out zinc pipe, take out zinc pump, drive unit.Take out zinc pipe one end and take out the zinc pump intake and join, the zinc liquid level that an end opening is immersed in the nitrogen cover is used for inhaling zinc liquid in the place, below slightly.Drive unit can be pneumatic or electronic, and its output shaft and the blades axes of taking out pump zinc be by mechanically coupled together, gives to take out pump zinc power is provided.Take out the zinc pump and be immersed in the outer zinc liquid of nitrogen cover, the zinc liquid relief outlet of taking out the zinc pump can be immersed in the zinc liquid, also can expose the zinc liquid level slightly so that judge whether take out new pump works.During work, the drive unit action is taken out the zinc pump zinc liquid is extracted out from the nitrogen cover is inner endlessly, and the cadmia zinc gray is also taken out of simultaneously.The characteristics of this method are, adopt the material (as SUS316L) of corrosion-and high-temp-resistant to make the pump housing, and flow is big, and it is strong to take cadmia zinc gray ability out of, can work continuously.Its shortcoming is: cost cost height, high temperature creep and corrosion cause the pump housing life-span short, and the easily sticking cadmia of pump is stuck, interrupts the quantity-produced process, influences ordinary production.
