Abstract
The invention relates to a method of heating tanks, such as galvanizing tanks, containing a bath of molten metal. Use is made of at least one element made of a refractory material which is thermally conducting and substantially gas-tight, particularly in relation to oxygen. The element is put into direct and permanent contact with the upper surface of the bath. A source of heat is positioned above or inside this element, making it possible to heat the latter and, by conduction, the bath itself
