Installation for the continuous coating of a strip, especially for the galvanizing of sheet steel

An installation for the continuous coating of a strip, comprising means for successively causing the strip to enter and pass through a molten bath of coating material and for causing the strip to leave the bath in an ascending and approximately vertical direction;

• means for equalizing the thickness of liquid coating material carried by the strip on leaving the bath;
• an enclosure surrounding the equalizing means, said enclosure being open towards the bottom and having side walls which dip into the bath, and having an upper wall provided with a narrow slit through which the strip leaves;
• means for maintaining a protective atmosphere in the enclosure;
• and at least one nozzle for blasting nuclei, arranged so as to blast onto the strip, above the equalizing means, a jet of gas charged with crystal nuclei of the coating material, the nozzle being placed inside the enclosure from which the strip leaves through said narrow slit and which is provided with means for maintaining a protective atmosphere inside the enclosure.
