Method and equipment for hot rolled plate colored forming continuous production

Abstract

The invention provides a method for the continuous production of the color-coated forming of hot-rolled plates and a device thereof. The method is characterized in that all processes are continuously completed on line. The method comprises the following steps: the head and tail of a hot-rolled steel band are welded together; the steel band enters a pickling tank to remove the oxide of the steel band surface and then the steel band enters a hot air drying segment to remove the moisture of the steel band surface; the steel band enters a roll coater 11 to coat the band surface, and then transmitted into a paint curing furnace 12 to cure and dry the band after coating, and the steel band with a certain temperature is blown by cold wind 14 to reduce the temperature of the steel band; the steel band enters the roller forming stage, so the steel band is transmitted into the roller 19 to carry out the roller forming; the steel band is allowed to has a certain waveform; the waveform steel band after the roller forming is transmitted into a flying shear 22 for definite distance cutting, in order to cut the steel plate according to the requirement; finally, the steel band is transmitted into a dual stacking to perform the stacking according to the height. The method improves the efficiency of production and saves the cost.

Description

technical field [0001] The invention belongs to the field of color coating production in the metallurgical industry, in particular to the field of forming plate production. Background technique [0002] At present, some of the original domestic production of formed plates use cold-rolled plates as the original plate, and the cost is high, which is 30-40% higher than that of hot-rolled plates as the original plate. With hot casting (Giesshitze), the continuous expansion and rapid development of the range of hot-rolled sheets makes it possible to use hot-rolled sheets as the original sheet. In ZL00811204.5, it is a hot-dip galvanizing production process using hot-rolled sheets as raw materials. In The date of disclosure is that the application number published on March 16, 2005 is 03146908.6, a hot-dip galvanized color-coated plate with a hot-rolled plate as a raw material plate. At present, the forming plate technology using hot-rolled plate as the original plate in China fi...

Problems solved by technology

The entire production process cannot be operated continuously, and the intermediate transportation links are complicated. Because of the need for atomization during painting, aerosol treatment wastes a lot of paint. However, this production method occupies a large area, high cost, low production efficiency, and high labor intensity.
