Product Specifications
Thickness: 0.2-20mm
Width: 600-3000mm
Formed coils are mainly hot-rolled coils and cold-rolled coils. Hot rolled coil is the processed product before the recrystallization of the steel billet. Cold rolled coil is the subsequent processing of hot rolled coil. The general weight of the steel coil is about 15-30T.
Product Classification
● Hotrolled, that is, hot-rolled coil, which is a slab (mainly for.
● Casting billet) as raw material, after heating, it is made into strip steel by rough rolling unit and finishing rolling unit.
● The hot strip from the last rolling mill of finishing rolling is cooled by laminar flow to the set point.
● The coil is rolled into a steel strip coil by a coiler, and the cooled steel strip coil can be used according to the different needs of users.
● After different finishing lines (leveling, straightening, cross-cutting or slitting, inspection.
● Weighing, packaging and marking, etc.) are processed into steel plates, flat coils and slit steel strip products.
production process
The production process of hot-dip galvanized sheet mainly includes: Original plate preparation → Pre-plating treatment → Hot dip plating → Post-plating treatment → Finished product inspection, etc. According to custom, often according to the pre-plating treatment method of.
The galvanized coil is composed of an aluminum-zinc alloy structure, which is composed of 55% aluminum, 43% zinc and 2% silicon solidified at a high temperature of 600 ° C. The entire structure is composed of aluminum-iron-silicon-zinc, forming a dense A kind of quaternary knot body.

Cold rolled coil (Coldrolled), commonly used in the steel industry, is different from hot rolled coil.
It refers to directly rolled into a certain thickness with a roll at room temperature and rolled into a whole roll with a winder
steel belt. Compared with hot-rolled coils, cold-rolled coils have a brighter surface and higher finish, but will
More internal stress is generated, and annealing treatment is often carried out after cold rolling.
Category: SPCC, SPCD, SPCE
Galvanized steel coils (Galvanized steel coils), galvanized refers to the metal, alloy or the surface of other materials is plated with a layer of zinc to play the role of beautiful, rust-proof and other surface treatment technology. Now the main method is hot-dip galvanizing.
