METHOD AND DEVICE FOR BLOWING A GAS ONTO A MOVING STRIP

Postupak kojim se djeluje puhanjem plina ili mješavine vode i plina na temperaturu trake (4) koja se kreće, u skladu s kojim postupkom se veliki broj mlazova usmjerava na svaku stranu trake, pri čemu su mlazovi usmjereni prema površini trake i tako su usmjereni da su točke udaranja (24, 34) mlazova plina ili mješavine vode i plina na površinu trake raspoređene na čvorišta dvodimenzionalne mreže, pri čemu se točke udaranja (24) mlazova na jednoj površini (A) trake ne podudaraju s točkama udaranja (34) mlazova koje se nalaze na drugoj strani (B) trake, naznačen time što mlazovi plina ili mješavine vode i pline dolaze iz mlaznica (23, 33) koje imaju oblik cijevi i koje se napajaju iz najmanje jednog spremnika za razdiobu (21, 31) i mlaznice se nalaze na takvom odstojanju od spremnika za razdiobu da se ostavlja jedan slobodan prostor za cirkulaciju plina ili mješavine vode i plina koji se odbija prema natrag paralelno s uzdužnim smjerom trake i okomito na uzdužni smjer trake.

The process comprises projecting gas jets or water/gas mixture jets on each side of the strip, and distributing the impacts of gas or water/gas mixture jets on each surface of the strip in nodes of a two-dimensional network. The jet impacts on one side (A) of the strip, and does not impact on the other side (B) of the strip. The gas or water/gas jets are obtained from tubular nozzles (23, 33) fed by a distribution box (21). The tubular nozzles extend away from the distribution box so as to leave a free space for gas or water/gas circulation.

The gas or water/gas jets are obtained from tubular nozzles (23, 33) fed by a distribution box (21). The tubular nozzles extend away from the distribution box so as to leave a free space for gas or water/gas circulation that is parallel or perpendicular to the longitudinal direction of the strip. The axis of gas or water/gas mixture jet forms a perpendicular angle with the strip surface. The two-dimensional networks for distribution of jet impacting on each side of the strip are hexagonal, periodical, same type and same pace. The impacts of jets on the same face of the strip distributed in
