Ceramic pressure rollers are critical components in galvanizing lines, designed to guide and stabilize steel strips while resisting extreme heat, corrosion, and abrasion. Made from high-performance alumina ceramics, these rollers offer superior wear resistance, thermal stability (withstanding temperatures up to 1,200°C), and anti-stick properties, preventing zinc adhesion. Their smooth surface ensures uniform coating thickness and minimizes strip scratches. Compared to traditional steel rollers, ceramic rollers extend service life by 3-5 times, reducing downtime and maintenance costs. Widely used in continuous galvanizing (CGL) and annealing lines, they enhance production efficiency and strip quality. Customizable in size and composition, they suit high-speed, high-precision industrial applications.
