FIELD: metallurgical heat power engineering, possibly bath-furnaces for melting easy-to-melt metals and applying coatings of such metals onto ready metallic articles, for example applying zinc coating onto nails.
SUBSTANCE: pre-chamber is mounted along the same axis with bath-furnace in its mean part and it is provided with lengthwise movable blinds. At lateral sides of furnace there are working zones - technological recesses open at side of environment. Heating is realized in mean part of bath-furnace and coating is applied onto articles in lateral working zones of bath-furnace.
EFFECT: enhanced efficiency of bath-furnace.
