METHOD AND FACILITY FOR COATING ON METAL BLANK BY MEANS OF HOT DIPPING Russian patent published in 2008 - IPC C23C2/00 C23C2/24 C23C2/40 

FIELD: metallurgy.

SUBSTANCE: metal blank is vertically passed through tank with melt and through located before tank guiding channel of specified height. In the area of guiding channel there are provided two located by both sides of inductor blank, creating electromagnetic field. Into guiding channel in the area of its extent by height it is fed melt with specified volume flow, which corresponds to part or all additional melt volume, fed at time unit, for supporting of wished melt level in tank. Facility contains tank with melt and located before the tank guiding channel, in the area of which by both sides of blank there are provided inductors for creation electromagnetic field, and into area of extent by height of this channel it is provided, at least, one pipeline for feeding of melt with specified volume flow, at that pipeline, coming into guiding channel is provided in the area of long side and in the area of butt end side of guiding channel. Quality of coating plating is increased at the expense of tank with melt which stay immovable at usage of electromagnetic lock.

EFFECT: increasing of coating quality.
