Method for the manufacture of extended steel products

A method for the manufacture of extended steel products, wherein an extended steel product surface is contaminated by oils and by at least one of organic and inorganic particles that are suspended or dissolved in the oils, said method comprising the steps of:

• following the shaping of the extended steel product by working, but before a subsequent treatment of the steel product, emitting from burners exhaust gases that interact directly with the surface of the steel product, fueling the burners with a fuel and an oxidant that contains at least 80% oxygen by weight, vaporizing and combusting oils that are present on the surface of the product, and directing the exhaust gases at the surface of the steel product at a velocity that is sufficiently high to blow away organic and/or inorganic particles from the surface of the steel product.
