Abstract

PURPOSE: To economize energy consumption and to minimize the size of an equipment, by applying a cooling-low temperature baking type finishing paint to a metallic strip after a baking-drying type primer is applied to the surface of the metallic strip to half harden through a heating-baking, and heating- baking the finishing paint to a temperature higher than its hardening temperature.
CONSTITUTION: A baking-drying type primer is applied to both surfaces of a pretreated metallic strip 21 with roll coaters 1 and 2, and the paint film is half hardened by heating the paint film at a temperature lower than its hardening temperature at which the paint is quickly hardened, in a drying oven 22. Then, a baking-drying type finishing paint is applied to both surfaces of the strip 21 with roll coaters 11 and 12, and both the paint films of the primer and the finishing paint are heated to a temperature higher than their hardening temperature in a hot air drying oven 14 and the paint films are hardened through the baking. After the paint films are hardened, the strip 21 is passed through a cold air cooler 15, a cold water cooler 16, and a drier 17, and thus, a painted metallic strip 24 is obtained. It is necessary to keep the finishing paint at a temperature ≥30°C by using a water cooling type cooling device 23.
