[China's First Garrett Coiler Completes Hot Commissioning]
Recently, the Garrett coiler independently developed by Qingdao Leiting Heavy Industry Co., Ltd., the first of its kind in China, successfully completed hot commissioning and passed steel on the first attempt at Severstal in Cherepovets, Russia. All equipment operating parameters and coil forming indicators met the standards, marking a major localisation breakthrough in China's core coiling equipment for large bar coils and a successful entry into the high-end metallurgical market outside China. The Garrett coiler is the core key equipment of large bar coil production lines, and its core technology has long been monopolised by overseas producers. To break through the technical barriers, the Leiting Heavy Industry R&D team carried out sustained research, completing multiple technical innovations in structural optimisation, coil stripping mechanisms, and automatic control logic, and obtained a series of independent patents. The team overcame industry pain points of conventional models, such as unstable coil shape, coil stripping jams, and poor reliability under high-temperature conditions. The equipment is adaptable to twist-free, tension-free coiling of multiple wire rod specifications, with neat coil forming, stable operation, and convenient maintenance, fully meeting the continuous production needs of steel mills in China and overseas.
