galvanized steel suppliers

Galvanizing refers to a rust-proof method of laying metallic zinc on the surface of iron or steel. Zinc is a metal with high corrosion resistance. It can insulate iron from oxygen and water, so that iron cannot undergo the chemical reactions required for rusting. Because zinc is more mobile than iron, even if the zinc plated appears Even if damaged, zinc can still prevent rust by electrochemical means of sacrificial protection. The main galvanizing methods include hot dip galvanizing (HDG), electro galvanizing (EG) and cold galvanizing.

Galvanizing methods include hot-dip galvanizing, hot-spray galvanizing, electro-galvanizing, cold galvanizing, powder hot-dip galvanizing, mechanical galvanizing and vacuum evaporation galvanizing, etc.

  • 1. Stainless steel crude steel smelting process

    At present, the smelting processes for producing stainless steel in the world are mainly divided into one-step, two-step and three-step methods, as well as new integrated production methods. The one-step smelting method is: molten iron + AOD (argon oxygen refining furnace); the two-step method is: EAF (electric arc furnace) + AOD (argon oxygen refining furnace). The three-step method is: EAF (electric arc furnace) + AOD (argon oxygen refining furnace) + VOD (vacuum refining furnace). In addition to several traditional production processes, the current integrated production process, that is, the production process from molten iron directly to stainless steel, is also adopted by many companies. The production process is: RKEF (rotary kiln electric furnace) + AOD (argon oxygen refining furnace).

  • 2. Stainless steel hot rolling process

    The stainless steel hot rolling process uses slabs (mainly continuous casting billets) as raw materials, and after heating, the rough rolling unit and the finishing rolling unit make strip steel. The hot steel strip coming out of the last rolling mill of finishing rolling is cooled to the set temperature by laminar flow, and is rolled into steel coils by the coiler. The surface of the cooled steel coils has oxide scale and appears black, commonly known as “stainless steel black coils” . After annealing and pickling, the oxidized surface is removed, which is called “stainless steel white roll”. Most of the hot-rolled products circulating in the stainless steel market are stainless steel white rolls.

  • 3. Stainless steel cold rolling process

    After hot rolling of stainless steel, some hot-rolled stainless steel products are directly used downstream, and some hot-rolled products need to be processed into cold rolling before use.

    For stainless steel cold rolling, stainless steel hot-rolled products with a thickness of 3.0-5.5mm are mostly used. After rolling processing by cold rolling equipment, stainless steel cold-rolled products are produced. Currently, there are two main production processes for stainless steel cold rolling: stainless steel single-stand cold rolling and stainless steel multi-stand cold rolling.

  • 4.Annealing and pickling unit

    After stainless steel is cold rolled, it needs to go through annealing and pickling units. The annealing of stainless steel after cold rolling is to eliminate work hardening through the recrystallization process to achieve the purpose of softening; the purpose of pickling is to remove the oxide layer formed on the surface of the steel strip during the annealing process, and to passivate the surface of the stainless steel. , improve the corrosion resistance of steel plates.

Flat Coils Into Steel Plate
For the final application, the coil needs to be flattened and cut into steel plates, so we flatten the coil and cut the coil into the required size of steel plate. In order to save the cost of container loading, it is loaded into a 20-foot container, so the cutting length is below 5800mm, usually cut into lengths of 2440mm and 5800mm according to requirements, and the width is usually 1220mm and 1500mm. After cutting the steel coil into steel plates, we can do black paint on the surface of the plates to make the plates rust-proof. Coil Cut Into Strip Service
