The new Vai Siemens De-Bars/Wire Rod Plant in Russia, will have a design capacity of 315,000 t of bars and 135,000 t of angles and channels per year.
The rolling line will comprise a walking hearth furnace, a continuous rolling mill with 18 Red Ring stands and quick-change system in the finishing area, a cooling bed, straightening and cutting machines and finishing equipment for bundling, tying and dispatching. Bars are in-line quenched for enhancing the mechanical properties.
The plant will be able to produce reinforced steel in bars of 10 to 40 mm diameter, spooled bars of 10 to 16 mm diameter and sections. Smaller diameters will be produced via a multi slitting process to maximize productivity. The spooled bars will be produced on a spooling line operating at a maximum finishing speed of 23 m/s, with a four-stand finishing mono-block, shears, in-line cooling, two spooling machines, as well as automatic tying and weighing machines.
To support the melting process, we have the BSE technology 3 lateral combined oxygen gas burners in operation, plus 3 post combustion burners and 1 lance manipulator with 3 probes (oxygen, carbon and lime)
