摘要： Device for heating metal material includes an elongated DFI burner arranged to be driven with gaseous oxidant and gaseous fuel and to be displaceable and longitudinally arranged with respect to the metal material. The burner includes longitudinal tubular vessels for fuel and for oxidant, arranged in parallel to one another and relative to the surface of the metal material. Each of these vessels has an opening through which the fuel and oxidant flow out and then converge in an ignition zone outside the respective vessels, where a flame is generated. Supply devices are arranged via a regulator to keep the pressure constant throughout the respective vessel during operation. Each of the vessels has a longitudinally displaceable piston for controlling the longitudinal extension of the flame in the longitudinal direction of the vessels.

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： Method for measuring the local temperature in an industrial furnace (1) equipped with a burner (3), where at least two temperature sensors (21, 22) are arranged at different locations in the furnace (1). A virtual temperature measuring point is created by the association of each temperature sensor (21, 22) with a certain weight factor, in that the measurement values from each temperature sensor (21, 22) are weighted together using these weight factors in order to thus achieve a virtual measurement value, in that the weight factors at every given point in time are individually controlled based upon the momentarily emitted power of the burner (3), and in that the virtual measurement value in turn constitutes control parameter for the control of the emitted power of the burner (3).

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.
