PLANT FOR THE CONTINUOUS HEAT TREATMENT OF STEEL STRIPS OR THE LIKE

摘要

A plant for the continuous heat treatment of steel strips (4) 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) 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. 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). The inductively heated steel strip is quenched by the first roller and the supplied steel in order to improve the energy efficiency of the process and to minimize the discharge of cooling agent to the environment.
