About production

Designed to remove oxide from the surface of hot-rolled steel. The leading and trailing ends of the metal are trimmed with guillotine shears, then the steel passes through pickling and rinsing baths to remove hydrochloric acid. After edge trimming, the metal is wound into a coil. The output is hot-rolled pickled steel in coils.

• Capacity500,000 tons per year
• Strip width800–1300 mm
• Strip thickness2.2–5.0 mm
• Pickling speedup to 150 m/min

Designed to roll hot-rolled pickled metal to the required thickness. The coil is loaded onto the uncoiler and the metal is rolled on the two-stand mill. When finished, the coil is strapped and passed to the continuous hot-dip galvanizing line.

• Capacity500,000 tons per year
• Strip width800–1250 mm
• Entry strip thickness2.2–5.0 mm
• Exit strip thickness0.28–1.2 mm

Heat treatment of work-hardened metal and application of a zinc coating. After alkaline washing, the strip passes through a thermochemical furnace, is immersed in a zinc bath, cooled and skin-passed. An anti-corrosion solution and preservation oil are applied — the finished coil is shipped to the customer.

• Capacity500,000 tons per year
• Strip width800–1250 mm
• Strip thickness0.29–1.2 mm
• Strip speed210 m/min

Application of a polymer coating to galvanized steel. The strip passes through alkaline washing, a conversion solution for adhesion, and primer and topcoat enamel on the face and reverse sides. The color is chosen at the customer's request; drying in the finishing furnace up to 245 ℃.
