Further, described union lever is telescopic rod.By the distance regulating telescopic rod to reach Distance geometry two air knife baffle plate devices of adjustment two heating units, adapt to the band steel of different in width.
Further, the cross section of described heating unit is Horseshoe, and steel edge portion can stretch into the hollow space of the Horseshoe of described heating unit.
Further, described heating unit is two slab constructions be arranged in parallel, and steel edge portion is positioned in the middle of described two slab constructions.
Further, radiator tube, electrothermal tube, hot air apparatus or inductor block is provided with in described heating unit.
Further, described union lever is provided with magnet setting device, and described magnet setting device comprises governing screw and setting nut, and described magnet is connected on described union lever by described governing screw and described setting nut.Governing screw on regulating magnet and setting nut can carry out between regulating magnet and band steel distance.
The advantage that the present invention has and positively effect are: owing to adopting technique scheme, heated, slow down the speed of cooling of steel edge portion coating by heating unit to steel edge portion coating, thus prevent the blocked up phenomenon of edge coating from occurring; Outlet pipe is provided with in air-knife baffle inside, and the buffering cavity connected with inlet pipe, in buffering cavity, be filled with high pressure gas from inlet pipe and form malleation through outlet pipe ejection, making the gaseous tension of steel edge portion more concentrated, better contact with steel edge portion; Before and after band steel, both sides are provided with magnet, prevent the shake of band steel by the magnetic attracting force of magnet to band steel, stabilized zone steel, prevent band steel from touching air knife, thus avoid air knife to produce damage to band steel, be with steel to stablize the thickness also contributing to control strip coating simultaneously.
