摘要： A method of heat treating stainless steel in the form of blanks, piping, tubing, strip, or wire-like material, after rolling the material, and in a heat treatment furnace at a temperature higher than about 900° C. The material is subjected to a preheating stage and a final heating stage, wherein in the preheating stage flames from burners are directed toward the surface of the material to impinge on the surface. Burners situated in the preheating stage are supplied with a fuel that burns with the aid of an oxidizing gas that contains gaseous oxygen. The material is held in the preheating stage long enough to obtain at least some degree of oxidation on the surface of the material, and the material is heated further in a following, final heating stage by burners situated in a furnace and that are supplied with a fuel and an oxidizing gas.

A related furnace is also provided.

摘要： Method for homogenizing the heat distribution as well as decreasing the amount of NOx in combustion products when operating an industrial furnace with at least one conventional burner using air as an oxidant. An additional oxidant including at least 50% oxygen gas is caused to stream into the furnace through a lance. The total amount of oxygen supplied is balanced against the amount of fuel being supplied through the air burner. Firstly, the combination of at least 40% of the supplied oxygen is supplied through the additional oxidant, the lance is arranged at a distance from the air burner of at least 0.3 meters, and the additional oxidant streams into the furnace through the lance with at least sonic velocity, and secondly the additional oxidant is supplied only when the air burner is operated at a certain lowest power or at a higher power.

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.

摘要： A method and apparatus for heating extended steel products, such as pipes, tape, or wire products or rods following working such as rolling or extrusion, to a heat treatment temperature, normally to approximately 50 to 900 degrees Celsius. The heating takes place as a result of the product being fed through a burner that has a central through channel into which the product is fed. Fuel and oxidant are supplied through channels that are outside of the central channel and are supplied at such a rate that the combustion of the fuel takes place in front of an outlet opening of the burner head of the burner.
