  • Method for enhancing the metallurigcal quality of products treated in a furnace
    Patent number: 6955730
    Abstract: The method and apparatus for enhancing the metallurgical quality of products treated in a furnace with several zones, wherein the temperature and the atmospheric conditions can be controlled. The applies to any type of product treated in a furnace, such as billets, blooms, slugs or slabs. Alternatively, this may be used by iron and steel manufacturers in the production line for sheets, plates, tubes, etc.
    Type: Grant

  • Combustion method comprising separate injections of fuel and oxidant and burner assembly therefor
    Patent number: 6910879
    Abstract: A method of combustion and a burner assembly wherein at least one fuel and at least one oxidizer are injected separately. The oxidizer comprises a primary oxidizer stream and a secondary oxidizer stream. The primary oxidizer stream is divided into at least two portions. One portion is injected close to the fuel whereby generating a first incomplete combustion. The second portion is injected downstream of the first injection point with the fuel source consisting of the remaining uncombusted fuel of the first incomplete combustion in addition to the fuel. The secondary oxidizer stream is injected downstream from the primary oxidizer stream, whereby resulting in combustion with the unreactive fuel gases remaining from the first combustion.

  • Method for enhancing the metallurgical quality of products treated in a furnace
    Publication number: 20040140024
    Abstract: The invention concerns the modification of the thermal profile developed by a product during treatment, in particular in a reheating furnace. The invention is characterised in that it consists in decreasing the treating time of the products, while increasing the available heating power, thereby enabling to reduce the thickness of the decarburized layer and/or the thickness of the calamine layer, hence decreasing melting losses.
