    摘要: A method is disclosed for preheating a metal strip in at least one direct fired preheating section of a furnace for limiting the oxidation of the metal strip. The method includes installing burners in the preheating section along its length for establishing a plurality of preheating sub-zones of unit length corresponding to one burner. The air and fuel settings for each burner are adjusted in accordance with a desired heat demand. Subsequent steps include operating a variable number of downstream burners at full power to establish a preheating zone of variable length to produce the desired heat demand, and extinguishing a second variable number of upstream burners to establish a corresponding variable recovery zone.

    摘要: A process is disclosed for the continuous thermochemical treatment of metal strip. It is useful with steel strip, of the oxidation-reduction type, in which the strip moves through a furnace in a protective atmosphere. The strip passes through at least one partial or total isolation device positioned within one or more sections of the furnace. The strip is heated in this isolation device in atmospheres having a dew point tailored to each strip according to the specific composition of the steel so that the atmosphere is oxidizing in the case of certain addition elements, but remains reducing in the case of iron.

    摘要: A process for the protective or decorative coating of a continuously moving metal sheet, in which the sheet, after having received its coating, is heated by electromagnetic induction in a tunnel oven in order to evaporate the solvents and to cure the coating. The solvents are continuously extracted from the chamber of the oven, wherein a gas at a temperature greater than the dew point of the solvents is injected into the oven and which is gastight and thermally insulated in order to keep the hot internal walls above this dew point.
