Hot rolled coils contain iron oxide layers and scales, making them unsuitable for direct use. At Prompt, we offer pickling and oiling services for HR coils to remove these rusty layers and scales, resulting in a bright surface finish. The application of oil and superior packaging ensures that the coils and sheets remain rust-free. Our HCL pickling line, with a width of 1650mm and a capacity of 0.72 Mtpa (60,000 tons per month), uses proven and reliable technology to process hot rolled carbon steel according to technical specifications. The pickling process involves removing oxide scales from the surface of the hot rolled steel by treating it with dilute hydrochloric acid. This process combines chemical reactions and mechanical separation of scales due to the evolution of hydrogen.
Skin pass roiling slightly reduces the thickness of the pickled coil to restore the desired thickness as per customer requirement.
