The production process of C, Z, U purlin rolling forming line mainly includes the following steps:
1. Material preparation: select the metal materials that meet the requirements, such as galvanized steel plate, aluminum alloy plate, etc., and cut them according to the production requirements to ensure that the material size meets the requirements of subsequent processing.
2. Pretreatment: Rrust and cleaning to ensure the clean and smooth surface of the material and improve the quality of subsequent processing.
3. Rolling molding: send the pretreatment material into the rolling molding machine, and gradually press the material into the required C, Z, U type purlins through a series of rolling molds. In this process, the parameters of the roller machine, such as pressure, speed, temperature, etc., need to be strictly controlled to ensure the molding quality.
4. Post-treatment: the formed purlin needs to be cut, punched and other subsequent processing to meet the needs of installation and use. At the same time, also need to carry out quality inspection, such as size inspection, appearance inspection, to ensure that the product is qualified.
5. Packaging and storage: Quality inspected purlins are packaged to prevent damage during transportation and storage. Packed purlins should be stored in a dry, ventilated place to avoid moisture and corrosion.
In general, the production process of C, Z, U purlin rolling forming line includes material preparation, pretreatment, rolling forming, reprocessing, and packaging and storage. Through the strict control of the quality and operation specifications of each link, we can ensure that the production of high-quality purlin products, to meet the needs of the construction industry.
