Painting refers to covering metal and non-metal surfaces with protective or decorative layers. With the development of industrial technology, painting has shifted from manual to industrial automation, and the degree of automation is increasing. As an indispensable component of the painting production line, the oven board plays a key role in energy-saving and insulation of the entire production line. At present, the oven board mainly uses high-density rock wool oven board, which is mainly suitable for drying ducts, ovens, ovens, tunnel furnaces, etc. of large and medium-sized coating production lines with high fire prevention and insulation requirements. United Crown Rock Wool Drying Board commonly adopts the process of side punching and double-sided embossing, with high-density rock wool core built-in. The thickness of the steel plates on both sides can reach 0.4mm to 12mm, and for stainless steel, it can reach 0.3mm to 1.0mm. The entire board thickness can reach 200mm, with excellent insulation effect and the ability to customize non-standard products. It is a leading enterprise in this field in China. The coating production line mainly consists of pre-treatment electrophoresis line, sealing primer line, intermediate coating line, surface coating line, finishing line and its drying system. The entire workpiece conveying system of the painting production line adopts a mechanized conveying method combining aerial suspension and ground sled, which runs smoothly, quickly and conveniently. It adopts PLC controllable programming and is programmed and controlled according to the actual requirements of the production process - implementing fieldbus central monitoring and automatic transfer operation in different zones.
