    摘要: A method continuously creates a bainite structure in a carbon steel, especially a strip steel by austenitizing the carbon steel; introducing the austenitized carbon steel into a bath containing a quenching agent; adjusting the carbon steel to the transformation temperature for bainite and maintaining the transformation temperature for a certain period of time; and then cooling the carbon steel. The carbon steel stays in the bath until a defined percentage of the bainite structure relative to the total structure of the carbon steel has formed. Residues of the quenching agent are removed from the surface of the carbon steel by blowing the same off when the carbon steel is discharged from the bath, and the remaining structure components of the carbon steel are then transformed into bainite in an isothermal tempering station without deflecting the carbon steel at all.

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 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: 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).

    摘要: A method is described for batchwise heat treatment of goods to be annealed which are heated in a heating chamber after scavenging air with a scavenging gas under protective gas to a predetermined treatment temperature, with the protective gas being conveyed through the heating chamber depending on the occurrence of impurities in different quantities. In order to enable the economic use of protective gas, it is proposed that the protective gas which is withdrawn from the heating chamber after the main occurrence of impurities and which is loaded with a residual quantity of impurities is conveyed, optionally after intermediate storage, into the heating chamber during the main occurrence of impurities of a subsequent batch before non-loaded protective gas is introduced into the heating chamber.
