Roll (roller) build-up welding
Surface modification for the new roll through hardening overlay has also been implemented! Welding overlay for heat-resistant and wear-resistant superalloys is also supported.
Build-up welding is a technique that involves welding different metals onto the surface of various metal materials (base materials) to restore the shape of areas that have been worn or damaged due to wear, cracks, corrosion, etc., and to improve surface properties such as wear resistance, corrosion resistance, and heat resistance. In particular, rolls and rollers used in continuous casting and rolling equipment related to steelmaking are subjected to harsh operating environments, and the extent of wear and damage due to heat, wear, and corrosion is significant. Our company not only focuses on restoring these base materials but also leverages the strengths of specialized welding material manufacturers to select welding materials that can withstand these operating environments, performing build-up welding to deliver products that match our customers' equipment. 【Features】 - Conduct surface modification aimed at restoring the shape of worn or damaged areas and improving wear resistance, corrosion resistance, and heat resistance. - Implement hard-facing build-up not only for worn rolls but also for surface modification of new rolls. - Utilize PTA welding to accommodate build-up welding of heat-resistant and wear-resistant superalloys based on Co and Ni. *For more details, please refer to the related link page or feel free to contact us.
