Abstract

An automatic coating technology for the color steel band includes such steps as pretreating which includes spray washing, passivating and baking, coating priming paint, baking, coating surface paint, baking and coiling. Its equipment features that its technological route is arranged in space shape for smaller size, the baking temp is automatically controlled, and the motors for main roller group and changeover rollers are cooperated for high attracting stability. Its advantages are less possessed ground, low energy consumption and high quality of product.

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...
