Abstract

PURPOSE:To reduce a height necessary for the titled apparatus and to raise a line speed, by dividing an alloying furnace into two parts, one of which is located along a vertical direction above a coating bath, and the other of which is horizontally located or downwards inclined through a non-contact course-changing device. CONSTITUTION:A metal sheet strip P is guided by a sinking roll 2, introduced into a coating bath 1, coated, vertically raised, and then fed through a controller for thickness of a coated layer, e.g. a gas wiper, into the first alloying furnace 4.1. The sheet strip P heated at a predetermined temperature in the furnace 4.1 is rotated to the horizontal or is inclined downwards by air fed from a high- temperature high-pressure air feed pipe h and injected through the nozzles n of a non-contact course-changing device 7. Thereafter, the coated metal is subjected to alloying treatment in the second alloying furnace 4.2, and then solidified by a forcible cooler 5. According to this apparatus, productivity can be enhanced without injuring the coated surface.
