W11S vs W12 plate rolling machine
When comparing the W11S and W12 plate rollers, it’s important to note that both machines are commonly used for plate rolling but differ in their design and capabilities. Here’s a comparison between the W11S and W12 plate rollers:
W11S Plate Roller
The W11S plate roller is a three-roll machine, also known as a three-roll asymmetrical plate rolling machine. It consists of three rolls, two lower rolls, and one upper roll. The W11S plate roller is primarily designed for medium to heavy-duty plate rolling applications. Here are some key features and characteristics of the W11S plate roller:
- Design: The W11S plate roller has an asymmetrical design, meaning that the two lower rolls are fixed in position, while the upper roll can be adjusted vertically to achieve different bending results.
- Rolling Capacity: The W11S plate roller is capable of rolling thicker plates and handling higher bending forces compared to some other plate rollers. It is suitable for rolling medium to heavy gauge plates.
- Bending Flexibility: The asymmetrical design of the W11S plate roller allows for different bending processes, such as pre-bending, rolling, and post-bending, depending on the requirements of the specific application.
- Ease of Operation: The W11S plate roller is relatively straightforward to operate, with intuitive controls for adjusting the position of the upper roll and controlling the rolling process.
W12 Plate Roller
The W12 plate roller is a four-roll machine, also known as a four-roll symmetrical plate rolling machine. It features four rolls, two lower rolls, and two upper rolls. The W12 plate roller is commonly used for various plate rolling applications and offers several advantages over the W11S plate roller. Here are some key features and characteristics of the W12 plate roller:
- Design: The W12 plate roller has a symmetrical design, with two upper rolls and two lower rolls arranged in a symmetrical configuration. This design provides improved balance and distribution of forces during the bending process.
- Rolling Capacity: The W12 plate roller has a wide range of rolling capacities, suitable for both light and heavy-duty plate rolling. It can handle various plate thicknesses and is capable of rolling thinner plates compared to the W11S plate roller.
- Bending Precision: The symmetrical design of the W12 plate roller ensures consistent and precise bending results. It offers superior control over the plate during the rolling process, resulting in higher accuracy and better-quality bends.
- Greater Bending Flexibility: The W12 plate roller allows for more complex bending operations due to its symmetrical configuration. It can perform operations like double pre-bending, pyramid rolling, and cone rolling more efficiently than the W11S plate roller.
Both the W11S and W12 plate rollers are reliable machines for plate rolling applications. The choice between the two depends on the specific requirements of the project, including the plate thickness, bending precision needed, and the complexity of the bending operations. While the W11S plate roller is suitable for medium to heavy-duty applications, the W12 plate roller offers greater bending flexibility and precision, making it ideal for a wider range of plate rolling tasks.
