Abstract
A method for introducing a cored wire into a bath of molten metal includes extracting the cored wire from a reel, and making it run into the molten metal bath, one part of the path traveled by the cored wire being formed in a guide tube with a distal end at a defined height above the metal bath's surface. The cored wire is driven and straightened under conditions practically not altering its substantially circular cross section and allowing it to be vertically introduced and penetrate into the depth of the bath. Elements for driving the cored wire from a reel, a guide tube for guiding the cored wire, and elements for straightening the cored wire are placed in front of its entry into the guide tube, the straightening elements giving the cored wire a straight direction without altering its circular cross section.
