On January 2, Shandong Guanzhou Zinc-Aluminum-Magnesium Unit Project succeeded in the hot commissioning at the first attempt. CERI is the contractor of the project. The technical indexes of the finished coil meet the design requirements, marking that the unit officially entered the trial production stage.

CERI undertook the overall design, supply and commissioning of the project, and provided a tailored aluminum-zinc (GL)/zinc-aluminum-magnesium (ZAM) product unit for Shandong Guanzhou. This is CERI's first aluminum-zinc (GL)/zinc-aluminum-magnesium (ZAM) product unit. Taking "quality production expansion, energy conservation and consumption reduction, environmental protection" as the core design concept of the project, CERI adopted the improved Sendzimir process to realize continuous hot-dip of strip steel after cleaning and reduction annealing. The maximum production speed of the unit process section is 180m/min, which meets the requirements of producing strip steel products with a thickness of 0.8mm and a width of 1,250mm; In order to meet the requirements of production of magnesium-containing (medium-aluminum and high-magnesium) coated products, the design of open flame heated all-fiber module is adopted, the combustion control is accurate and stable, the furnace temperature adjustment response is rapid and accurate, and the quality of the strip steel surface is excellent after open flame heating; The cooling section adopts a special bellows structure design to ensure the accurate temperature of the strip steel entering the zinc pot. The post-coating cooling is provided with several plate temperature measuring devices, and the cooling rate of each section fully ensures the formation of zinc-magnesium alloy crystal phase structure and grantees that the quality of zinc-magnesium coat meets the standard. The coating products include CQ, DQ and FH industrial products.
