Fast curing method and device used after electrostatic coating performed on surfaces of strip steel with powder

Abstract

The invention relates to a steel strip coating method and device, in particular to a fast curing method and device used after electrostatic coating performed on the surfaces of strip steel with powder, and belongs to the technical field of steel strip coating. The fast curing method used after electrostatic coating performed on the surfaces of strip steel with the powder comprises the following steps that (1) a steel strip is uncoiled by an uncoiling device; (2) precleaning is performed with a degreasing device; (3) cleaning is performed with a secondary cleaning device; (4) chemical coating is performed with a chemical coating device; (5) curing is performed with a curing furnace; and (6) coiling is performed by a coiling device; the strip steel passes a melting unit of the curing furnaceafter being chemically coated, so that powder coatings of the upper surface and the lower surface of the strip steel are each in a molten state; then, the strip steel passes a levelling device of thecuring furnace to make the coatings of the strip steel cured evenly; the cured coatings of the strip steel enter a cooling device and are cooled; the melting unit is heated and radiated by using radiant plates; and the levelling device is vibrated by using an ultrasonic vibration device.

Description

technical field [0001] The invention relates to a steel strip coating method and a device thereof, in particular to a rapid solidification method and a device thereof after electrostatically coating powder on the surface of a strip steel, and belongs to the technical field of steel strip coating. Background technique [0002] The continuous coiled steel strip is painted before being cut, shaped and made into finished products, and the pre-coated steel plate is called color coated steel plate. Now the color coated board technology has become the main industrial coating technology. The production line for strip coating is: uncoiling auxiliary support, uncoiler, coiling trolley, saddle, 1# uncoiling pinch machine, whole line bracket, 2# uncoil pinch machine, converging pinch machine, flattening machine , 1# tensioner, independent steering roller, front looper, 1# small idler, 1# centering machine, detection device bracket, 2# tensioner, 1# idler, pre-processing unit, power squ...

Problems solved by technology

[0006] Although the above-mentioned patents solve the coating technology of large-size plate spraying and "replacing paint with powder" and improve the production efficiency of color steel, there are still problems that the coating of the strip steel cannot be uniformly coated and cured after the coating is cured.
