Description
Technical field
The invention belongs to technical field of steel rolling, relate to arrangement and the ultrasonic unit of strip post processing continuously dip coat production line Coating Weight Control device.
Background technology
The etch-proof important means of iron and steel is exactly by its plated surface last layer non-ferrous metal, and such as: aluminum, zinc etc., these non-ferrous metal Performance comparision are active, produce fine and close oxide layer with the oxygen reaction in air, thus play etch-proof effect.Generally having plating and hot dip two kinds, plating due to relatively costly and seriously polluted, to make to be used less, hot dip just becomes the main flow in this field.
The method of hot dip is by non-ferrous metal heating and melting in a pond high temperature resistant, corrosion resistant, commonly referred to as " zinc pot " or " aluminum pot ".The annealed stove of strip steel run continuously, annealing furnace is heated to the temperature of plating bath, carries out hot dip subsequently into zinc pot or aluminum pot after being annealed by strip steel.Strip steel leaves zinc pot after plating bath or aluminum pot enters air, and now, belt steel surface is attached to substantial amounts of non-ferrous metal liquid, needs through further processing so that uniformly and THICKNESS CONTROL is in rational scope at belt steel surface for coating.
Traditional coating controls to use air knife, big-flow high-pressure air-flow sprays from flat air knife nozzle, it is ejected into belt steel surface, form one gas type scraping knife, coating unnecessary for belt steel surface can be scraped and chip away by this type scraping knife, can also efficiently control the uniformity of coating, the scheme that this coating controls is used in hot dip non-ferrous metal field in a large number.But this scheme has following obvious a defect:
1, substantial amounts of slag is produced.Owing to big-flow high-pressure air-flow has violent washing away and stirring action to plating bath liquid metals, non-ferrous metal is made to generate " compound of non-ferrous metal-ferrum " and " non-ferrous metal-oxygen compound " with iron-based body and the air reaction of strip steel, these compounds can solidify generation slag, or swim in the surface of non-ferrous metal liquid, or sink to the bottom of a pan.These slags finally will become refuse and pull out from pot, on the one hand waste expensive non-ferrous metal, and on the other hand can remain in belt steel surface forms obvious surface defect.
2, noise pollution.Big-flow high-pressure air-flow can produce high-decibel noise, and the air knife of different model can produce the noise of 80～130 decibels.
3, dust pollution.Non-ferrous metal liquid is washed away by big-flow high-pressure air-flow, can produce substantial amounts of non-ferrous metal dust, and floating diameter is about the scope of 20 meters.
4, limit line speed, and thinner coating is not easily accomplished.Line speed is the highest, and the non-ferrous metal liquid that strip steel brings out from body lotion is the most, it is necessary to the bigger unnecessary coating of air pressure scraping.On the one hand due to noise and the impact of dust, the pressure limiting air knife promotes further；On the other hand high-pressure high-flow air knife can produce more slag, the most uneconomical, also can deteriorate surface quality.
Utility model content
The deficiencies in the prior art in view of the above, the purpose of this utility model is to provide a kind of plating control device and ultrasonic unit, it is possible to decrease produces the quantity of slag, promotes panel quality, solves to plate at high speeds a difficult problem for relatively thin coating.
For achieving the above object and other relevant purposes, technical solutions of the utility model are as follows:
A kind of plating control device, including strip steel and plating solution pond, the position leaving plating solution pond liquid level at strip steel is provided with ultrasonic unit, described ultrasonic unit be provided above air knife apparatus.
Utilize ultrasonic unit to reduce the viscosity of non-ferrous metal liquid in certain scope, thus reduce the weight of the non-ferrous metal liquid that operating strip steel is taken out of from plating solution pond (zinc pot or aluminum pot).The vibrations that ultrasound wave produces in metal liquid, can make to stick to the metal liquid generation splash effect of belt steel surface, and part metals liquid can be peeled off from belt steel surface automatically, thus further reduces the non-ferrous metal liquid that belt steel surface adheres to.It is provided above air knife device for scraping, under the same terms and operating mode, compared with tradition air knife, it is only necessary to less gas pressure and flow just can realize accurately controlling thickness of coating at ultrasonic unit.The product quantity of slag so can be greatly reduced, save non-ferrous metal, promote board surface quality；Reduce noise and the pollution of dust；Reduce air knife and the design of air sword blower fan and the cost of manufacture；Break through the bottleneck of speed of production；Solve to plate at high speeds a difficult problem etc. for relatively thin coating.
