Embodiment Construction
[0029] Below in conjunction with embodiment and accompanying drawing thereof, further explain:
[0030] See attached picture. figure 1 The main process steps and conditions of the embodiment are listed in the block diagram. The production process of the color steel strip automatic coating line of the present invention, its process flow includes the pretreatment process of the steel strip, the primer coating process, the primer baking process, the top paint coating process, the top paint baking process and The traction and winding process sections, the pre-treatment process section is mainly composed of degreasing spray washing, water rinsing, drying, passivation and re-drying process. According to the characteristics of the equipment not moving and the workpiece moving, the following improvements are highlighted: In the treatment process section, two-stage hot water spray washing and three-stage clear water spray washing processes are added, which improves the surface cleanli...

The invention discloses an improved full-automatic color steel plate coating device. A production process comprises a steel belt pretreatment process section, a priming paint coating process section,a priming paint stoving process section, a finish paint coating process section, a finish paint stoving process section and a traction coiling process section. In the pretreatment process section, thedrying process executed after spray washing and passivation is reinforced, the process path is designed upward to be in a space S shape, the priming paint stoving and finish paint stoving processes are carried out in a paint stocking room in an integrated mode, and the drying and paint film stoving temperature is automatically controlled in corresponding equipment devices. A main shaft roller setof a traction device and a steering main shaft roller motor are cooperated so as to facilitate variable frequency control, and stable traction of a steel belt can be easily achieved. The plant production line ground occupation length is shortened, energy consumption is reduced, and the product percent of pass is improved. The product percent of pass reaches 95-98%. The production line is applicable to the automatic coating process of small-specification steel color belts.
Description
technical field [0001] The invention relates to the coating of the surface of metal materials, specifically a production process including degreasing and passivation pretreatment on the surface of the steel strip, coating primer and topcoat with a roller, and post-treatment of the coating after baking and equipment. Background technique [0002] Color steel belt products are widely used in the production of rolling gates. Existing color steel strip production line equipment and processes are commonly found in affiliated enterprises of major steel plate factories. The price of imported equipment is extremely high. Although the degree of automation is high, the advantage in production efficiency is not obvious, and the specifications are also too large. Small-sized equipment is often found in self-made, but there are problems such as large equipment footprint, long routes, high energy consumption, and low production efficiency. The process is also relatively simple, resultin...
