Steel Wire Rods By Uic Wires Limited

We have gained trust of our esteemed clients in exporting, manufacturing and supplying an extensive range of Steel Wire Rods for our valued clients in Kolkata, West Bengal, India. Steel wire rods which are received at the factory gate contain mill scale. Mills scales are rust, oxides of iron, mainly FeO, Fe2O3 and Fe3O4, which develop on the surface of the rods when they are stored for prolonged periods. Before the rods are taken for processing on the wire drawing machine, these mill scales and rust have to be removed. The removal of such scale and rust is done through chemical cleaning. In this process, the rod coil is immersed in acid solution of Hydrochloric acid (HCl). Acid penetrates through the cracks in the rust and scale and reacts with the virgin steel. The rust and scales become loose and fall off the surface.
