INSTALLATION FOR CONTINUOUSLY APPLYING COATING ONTO METALLIC STRIP Russian patent published in 2005 - IPC

FIELD: metallurgy, namely continuous application of coating onto rolled strip by dipping it in melt metal, possibly in aggregates for continuous hot zinc plating.

SUBSTANCE: installation includes arranged according to manufacturing process heat insulation box with inclined duct; guiding member in the form of pair of rollers; bath with melt; fluidic device; pair of discharging rollers arranged with possibility of vertical motion in zone between fluidic device and tensioning rollers. Pair of discharging rollers and roller pair of guiding member are mounted with possibility of motion along their axes; barrels of their rollers have sections that may be rotated separately. Generatrix of boundary sections of barrel of one roller of roller pairs is concave and generatrix of boundary sections of barrel of other roller of roller pairs is convex. Radius of concave and convex generatrices is no less than 0.004 α L_b, where α - inclination angle relative to horizon of line being tangent to lateral edge of barrel, L_b - length of roller barrel.

EFFECT: enhanced quality of coating due to stability of strip at applying coating provided by normalized elastic bending of lateral portions of strip.
