    摘要: The invention relates to a heat exchanger (1) for an annealing furnace for exchanging heat between two fluids, comprising a tubular profile which comprises heat exchanger fins on its outside jacket and which is associated on at least one face side (3) with a connecting flange (4) with at least one flow opening (8) for one of the two fluids, especially a hot gas. In order to provide advantageous constructional conditions it is proposed that the profile is a profile tube made of a folded sheet whose heat exchanger fins (7) aligned in the longitudinal direction of the profile are formed by the corrugated profile, especially the corrugated flanks, of the folded sheet.

    摘要: A plant for the continuous heat treatment of steel strips (4) or the like has a nonmagnetic insulated housing (1), in which two axially parallel unheated rollers (2, 3) are disposed at a distance from each other. To the first roller (2), the steel strip (4) or the like is supplied, which is then wound around the second roller (3) and as a secondary winding gets back to the first roller (2) through a transformer plate assembly (7) and is discharged from said second roller. The primary winding (10) with a corresponding number of turns is disposed outside the housing (1). The housing (1) is filled with a protective gas and has means (11, 12) to ensure a uniform temperature level and distribution in the housing (1).

    摘要: The invention relates to a method for continuously creating a bainite structure in a carbon steel, especially a strip steel. The method comprises the following steps: the carbon steel (1) is austenitized (3) at a temperature exceeding the austenitizing temperature; the austenitized carbon steel (1) is introduced into a bath (2) containing a quenching agent (21) in order to cool the carbon steel (1) to a temperature lying below the austenitizing temperature; the carbon steel (1) is adjusted to the transformation temperature for bainite and is maintained (13) at the transformation temperature for a certain period of time; and the carbon steel is then cooled (17). In order to further develop the method, the carbon steel (1) penetrates a bath (2) containing a quenching agent (21) until a defined percentage of the bainite structure relative to the total structure of the carbon steel (1) has formed in the bath (2) containing the quenching agent (21) following the austenitizing process, residues of the quenching agent (21) are removed from the surface of the carbon steel (1) by blowing the same off when the carbon steel (1) is discharged from the bath (2), and the remaining structure components of the carbon steel (1) are then transformed into bainite in an isothermal tempering station (13) without deflecting the carbon steel (1) at all when the same penetrates the isothermal tempering station (13).

    摘要: A tower furnace for heat treatment of metal strips having a pre-heating section (3) and a high-temperature section (5) connected thereto at the top forming a housing (4) separate from the pre-heating section (3) is described, whereby the pre-heating section (3) equipped with a preferably gas-heated muffle (7) exhibits a connecting stopper (6) made of heat-insulating material for the high-temperature section (5) inserted into the muffle (7). To create advantageous structural conditions it is proposed that the high-temperature section (5) is also fitted with a preferably gas-heated muffle (12) which encloses the connecting stopper (6) externally and connects to this in a gas-tight manner preferably by way of a fluid seal (14).
