Frequently Asked Question
Do you have any question?
Four-fold or four-high rolling is a metalworking process that involves passing a metal strip or sheet through a series of four rollers arranged in a specific configuration to achieve precise thickness reduction and improve the mechanical properties and surface finish of the material.
The four-high rolling configuration consists of two larger diameter working rolls positioned above and below the material, and two smaller diameter backup rolls positioned on either side. The material is passed between these rolls, and by adjusting the gap, speed, and pressure, the process achieves controlled reduction in thickness and ensures uniformity in the rolled metal product.
Four-fold or four-high rolling is widely used in industries such as automotive, aerospace, construction, and manufacturing. It is particularly suitable for producing thin and flat metal products, including sheets, foils, and plates, where precise thickness control and high-quality surface finish are crucial.
The four-fold rolling process is controlled and optimized by adjusting various parameters, including the gap between the rolls, roll speeds, and applied pressure. Advanced monitoring and feedback systems are often employed to ensure consistent and accurate thickness reduction, resulting in high-quality rolled metal products.
Four-fold rolling offers enhanced control and precision in thickness reduction, resulting in improved surface finish and mechanical properties of the rolled metal product. The configuration allows for better distribution of the applied forces, reducing the risk of material defects and providing greater uniformity in the final product.
