The arc template is a testing tool used to check whether the bending radius of each section of the continuous casting machine meets the design requirements. It is also a key measuring tool to ensure that the continuous casting machine can successfully pull the billet in one go. Due to the particularly high requirements for the design accuracy of arc templates, the manufacturing accuracy of bending radius is generally required to be ± 0.02~0.05mm, the flatness requirement is ± 0.05mm, and the parallelism requirement is ± 0.03mm. Before our company produced arc templates, qualified ones were imported from abroad, which were expensive, made of carbon steel and stainless steel, very bulky, and difficult to detect.
Through extensive exploration and practice, and based on our company's technical expertise, we have discovered a material that is particularly suitable for processing and manufacturing curved templates for aircraft beams. That material is super strong aluminum alloy, with a foreign grade of 7075. It is made through cold processing and does not require heat treatment during the processing. The arc template processed with this material is lightweight, high-precision, and can be stored at normal temperatures, ensuring technical requirements. Our company has manufactured arc templates for metallurgical enterprises such as Ansteel, Benxi Iron and Steel, Wuhan Iron and Steel, Maanshan Iron and Steel, Taiyuan Iron and Steel, etc., all of which have achieved a success rate of 100%. It has saved a large amount of foreign exchange for enterprises and the country, filling the gap in the domestic market.
