Embodiment Construction

[0006] The present invention will be further described below in conjunction with specific embodiments.

[0007] The strip steel coating process of color steel plate includes: (1) After the strip steel is dried in the chemical coating drying furnace, it enters the primary coating machine through the deviation correction and centering machine, and the surface of the strip steel is coated for the first time; (2) After the steel is coated with paint, it enters the primary coating furnace to dry the primer, and the strip steel coming out of the primary coating furnace is soaked in the cooling device and cooled by the centering machine to harden the coating (3) and then the strip steel enters the finishing coating machine For the second coating, there are 2 fine coating machines on the line, which can be used alternately; (4) then enter the fine coating furnace, heat the strip steel, and dry and solidify the coating; (5) the strip coming out of the fine coating cooling device Steel,...

Abstract

A strip steel coating technology for a color steel plate comprises steps of first, placing the strip steel into a primary coating machine via a correction centering machine after dried the strip steel via a coating drying furnace and coating the surface of the strip steel for the first time, second, drying the base coat by the primary coating furnace after the strip steel is coated with paint, immersing the strip steel into a cooling device after discharged out of the primary coating machine and cooling the centering machine to harden (3) a coating layer, third, placing the strip steel into a refined coating machine for secondary coating, fourth, heating the strip steel and drying and solidifying the coating layer, and fifth, immersing and cooling the strip steel after discharged out of a refined coating cooling device via the centering machine. Two refined coating machines are provided on line and can be alternatively used.

Description

technical field [0001] The invention belongs to the field of manufacturing color steel plates, and in particular relates to a strip coating process for color steel plates. Background technique [0002] The coating process of strip steel is an important process section in the manufacture of color steel plates. The strip steel is coated with a finish coater. The color change time of the topcoat is long and the process is complicated; the production cost is high. Contents of the invention [0003] The object of the present invention is to provide a steel strip coating process for color steel plates, which has high production efficiency, safety and reliability. [0004] The technical solution of the present invention is: the steel strip coating process of color steel plate, comprising: (1) after the strip steel passes through the chemical coating drying oven and dries, it enters the primary coating machine through a deviation correcting and centering machine, and the surface o...
