Activity Description

The production process of hot-dip galvanized coil includes pre-treatment of cold-hardened coils, hot-dip galvanizing, cooling, leveling, cutting, packaging, and other processes. It covers energy consumption, material consumption, waste treatment, and environmental emissions required during the production process.

Process Description

Q235B carbon steel hot-dip galvanized coil is a material of carbon structural steel treated by the hot-dip galvanizing process. Q235B is a grade in the Chinese standard GB/T 700, referring to low carbon steel, which boasts outstanding ductility, toughness, and weldability. The hot-dip galvanizing treatment is a process in which the Q235B carbon steel coil is dipped into molten zinc to form a tightly adhered zinc layer on its surface. This layer of zinc not only effectively protects the steel from rust but also provides a certain level of wear resistance and impact resistance. This protective mechanism of hot-dip galvanized coil is particularly suitable for applications in outdoor or corrosive environments, such as construction, automotive, bridges, power facilities, and other various industrial structures.

Technology comment

This technology is an efficient steel processing method that combines two crucial steps, annealing and galvanizing, to produce galvanized steel with superior corrosion resistance and good mechanical properties. The cold-hardened coil is heated to a certain temperature and then slowly cooled in a controlled environment to improve the mechanical and processing properties of the steel. The annealing process can eliminate internal stresses in the steel, making the material softer and easier to process. Next is the galvanizing process, in which the steel is dipped into molten zinc. This step forms a zinc coating on the surface of the steel, providing anti-corrosion protection. Before galvanizing, the surface of steel needs to be thoroughly cleaned to ensure that the zinc coating can adhere uniformly to the surface. After galvanizing, the steel coil undergoes cooling and surface treatments (such as passivation or applying rust-preventative oil) to further enhance its corrosion resistance and appearance quality. Finally, the hot-dip galvanized coil, which has undergone annealing, is inspected for quality assurance to ensure it meets specific standards, and then it is packaged for subsequent use or processing. The raw material for the hot-dip galvanized coil is processed from short-process steelmaking products.
