ANDRITZ to supply key process equipment for new hot-dip galvanizing lines for Tangshan Iron and Steel Group, China

Monday, Oct 26, 2015

International technology Group ANDRITZ has received an order to supply two continuous furnace plants for two new hot-dip galvanizing plants at Tangshan Iron and Steel Group, China. The two lines will have a combined annual total capacity of 670,000 tons and are designed to produce high-strength steel grade for the automotive industry. Start-up is scheduled for the first quarter of 2017.

The furnaces, which form the heart of the plant, are fitted with highly efficient low-NOx burners. In order to guarantee maximum cooling rates, the plant uses the new fast cooling system DRJC (Differential Rapid Jet Cooling) patented by ANDRITZ METALS. DRJC sets new international standards compared to existing plants through highest cooling rates with constant and controlled cooling across the entire strip width. In addition, the new technology adjusts to the respective strip width, thus helping to save energy. The scope of supply also includes automation equipment and key process components, such as the zinc stripping air-knife system and shears. Both lines are designed to handle strip with thicknesses ranging from 0.18-3 millimeters and widths from 850-1,600 millimeters.

This order follows the successful supply and start-up of furnaces and process equipment for another hot-dip galvanizing system and a continuous annealing line at Tangshan Iron and Steel Group that were ordered from ANDRITZ METALS two years ago. Only 21 months passed between the contract entering into force and the production of the first coil.
