摘要：
A method for the manufacture of extended steel products. The steel product is initially contaminated by oils and by at least one of organic and inorganic particles that are suspended or dissolved in the oils. Following the shaping of the steel product by working but before the subsequent treatment of the steel product, burners emit exhaust gases that interact directly with the surface of the steel product. The burners are driven by an oxidant that contains at least 80% oxygen by weight, whereby oils that are present on the product are vaporized and combusted. The exhaust gases interact with the surface of the steel product with a speed that is sufficiently high to blow away organic and/or inorganic particles from the surface of the steel product.
