On August 28, the galvanized aluminum-magnesium unit in Cold Rolling Project of Shanxi Jingang contracted by CERI, the EPC contractor, successfully completed one-time hot load test run and produced the first coil of steel. The unit operates well, the system is stable, and various indicators such as product plate type, thickness and surface quality meet the contract requirements. The galvanized aluminum-magnesium unit officially enters the trial production stage.

The galvanized aluminum-magnesium unit is designed with an annual output of 350,000 tons of zinc-aluminum-magnesium (6%-11%Al) coating products, which can be widely used in photovoltaic, household appliances, equipment manufacturing, new energy and other industries. The unit is completely independently designed by CERI and it can realize the application of new technological achievements. It is equipped with advanced equipment technologies such as full-automatic coiling, narrow lap welding, efficient cleaning + electrolysis, RTF vertical annealing furnace, low energy consumption-low NOx-high-precision radiant tube heating, high-precision plate temperature control, high-precision nitrogen gas knife, zinc ash control at furnace nose, ceramic induction zinc pot, special rapid cooling after plating, automatic control of zinc layer, flatness control of large roll system finishing + tension leveling, chromium-free roll coating passivation, online roll surface cleaning, etc. It can realize automatic control of the whole process to ensure that the process equipment is leading in China, and the maximum process speed can reach 180 m/min.

The Cold Rolling Project of Shanxi Jingang is the first full-process cold rolling project in China undertaken by CERI, representing the highest level of domestic cold rolling equipment construction.
