Pickling and Oiling Process
Steel pickling is a chemical cleaning process that eliminates rust, scale, and impurities from the steel surface. Our continuous coil-to-coil and sheet picklers use hydrochloric acid tanks to remove scale formed during steel production. The scale-free surface is then treated with electrostatic oiling or other controlled oiling methods for protection. We also offer non-oil alternatives like dry lube and Pickled Dry.
Pickling Vs. Blasting
Pickling and blasting both aim to remove mill scale from the steel surface and apply a rust inhibitor for protection. However, the impact of these processes on fabrication and finishing differs.
Effects of Blasting
The blasting process involves abrasive particles that create small micro-craters on the steel surface, leading to an uneven surface that affects laser cutting precision and paint finish quality.
Pickling and Surface Characteristics
Pickling removes the flaky scale from hot-rolled steel, resulting in a smooth and consistent surface ideal for painting and enameling. HRPO steel is also easier to weld due to fewer surface contaminants affecting the weld integrity.
Hot Rolled Pickled and Oiled steel, or HRPO, is a versatile material in steel manufacturing, offering improved properties and surface finish through a specific production process. HRPO steel is hot rolled, pickled, and oiled to achieve the desired results. The steel is heated to high temperatures, passed through rollers, dipped in acid to remove impurities, and coated with oil for corrosion protection
