Technical field
The utility model relates to a kind of low frequency electromagnetic field envelope stream device that is used for hot dip process, belongs to the hot dip process field.
Background technology
Hot-dip galvanizing sheet steel has been widely used in building, household electrical appliances, automobile industry.The main technical process of continuous hot galvanizing technology is: raw material preparation → plating pre-treatment → hot dip process → plating aftertreatment → inspection after construction etc., hot-dip coating installation is the key equipment of unit.At present, the zinc pot major part that the hot dip process production line sold on the market uses is the ceramic zinc pot of closed bottom, and the steel part that is immersed in zinc liquid is too much, comprises the sinking roller, stablizes the fire grate of roller, the supporting structure of the two and reductive annealed oven.This zinc pot system is complex structure but also have a lot of drawbacks not only: on the one hand, device in the zinc pot can be subjected to the etch of zinc liquid, even use the manufacturing of anti-zinc corrosive material, the wearing and tearing of sinking roller and stable roller roll surface and axle sleeve and corrosion are still very serious, need often to change and maintenance, so not only reduce operating efficiency, and improved labour intensity; On the other hand, after the device in the zinc pot was subjected to the etch of zinc liquid, a large amount of ferro elements entered the zinc pot, influences the purity of zinc liquid, the remote effect galvanizing quality; In addition, the sinking roller is passive deflector roll, relies on the frictional force of band steel and roller surfaces to drive fully, and roll surface has deviation slightly or produces relative movement, and the band steel easily is scratched, and reduces quality product.
At present, mainly concentrate on about the research of continuous hot galvanizing equipment and to improve sinking roller, axle sleeve on the life-span, the carbon tungsten alloy coating that the bulk material of the roller that for example sinks adopts the stainless steel, heat-resisting steel material or the spraying abrasion-proof that contain multiple alloying constituent to decrease; Carbon tungsten alloy or the advanced ceramic bearing of use in dip-roll neck slipper surface spraying abrasion-proof damage.
Summary of the invention
The purpose of this utility model is to provide a kind of production efficiency height, cost low, the low frequency electromagnetic field envelope stream device that is used for hot dip process of good product quality.
Technical solution: the utility model zinc pot below is provided with roll chamber, is provided with the envelope circulation road between zinc pot bottom and the roll chamber top, and the envelope circulation road outside is symmetrically arranged with electromagnetic inductor; Have band steel hand-hole on the roll chamber sidewall, be provided with down deflector roll and following tension device in the roll chamber, following tension device is positioned at the top of deflector roll down, is filled with low dew point nitrogen in the roll chamber; Zinc pot top is provided with air knife, and the air knife top is provided with deflector roll, and last deflector roll one side is provided with tension device, and last tension device is arranged at the steel hand-hole face that stands facing each other mutually of being with.
Envelope circulation road cross section is the rectangle or the rectangle of corner arc transition, and envelope circulation road thickness is 5-80mm, and width is greater than strip width.
The low-frequency range of electromagnetic inductor: 30-400hz.
The zinc pot is that metal or stupalith are made.
The envelope circulation road adopts pottery or non-conducting material to make.
The utility model adopts the electromagnetic enclosed slot mode, and no any device in the zinc pot can omit sinking roller system, can also realize that the indifference of different coating such as pure zinc coating, alloying coating, zinc-aluminium coating, aluminium-zinc coating is switched, and improves zinc-plated efficient.
The utility model is owing to rely on the electromagnetic force of inductor block to seal plating bath, solved the etch of zinc pot interior arrangement and band steel and a series of problems of being brought such as contacted with the roller that sinks, and has epoch making significance for raising steel band quality and output.
The utlity model has following advantage:
(1) cancellation sinking roller, thus some coating surface defectives of sinking roller strap can be eliminated, for example scuffing that causes of coating surface cadmia and steel band and sinking roller relatively sliding etc.
(2) the zinc pot is littler than traditional zinc pot volume, thereby has reduced the total amount of zinc liquid.
(3) save the off-time that brings because of maintenance sinking roller and fire grate, thereby improved product production, reduced waste product rate and labour intensity.
(4) reduced product cost,, also do not needed preheating sinking roller because there is not the maintenance problem of sinking roller and fire grate.
(5) can improve tension force in the reductive annealed oven, improve the plate shape of hot dip process steel plate, open roller arrangement because removed the heat in the reductive annealed oven.
