    • The invention concerns heating metal strips or other coilable strand metal object to an elevated temperature, wherein the metal object is passed in a heating section (5) through a furnace chamber (17) that is made at least partly of an insulating and electrically non-conductive material while being heated through transverse flux induction heating (TFIH) by means of transverse flux induction heating elements (15, 16) located outside of said chamber which contains a protective non-oxidising gas or gas mixture. The invention is characterised in that the metal object is a stainless steel object that has been cold rolled to a very high degree of surface reflectively, that the cold rolled stainless steel object is passed through said furnace chamber and is heated in said chamber to a processing temperature between 700 and 1200 DEG C, that the cold rolled stainless steel object is maintained at said temperature between 700 and 1200 DEG C for long enough for the steel to recrystallize completely, and that the heat treated metal object then is rapidly cooled directly from the processing temperature, in an airtight cooling section (6, 27) through which the non-oxidising gas is passed, to below a temperature of 600 DEG C.
    • 本发明涉及将加热金属带或其他可卷曲的金属丝物体加热至高温,其中金属物体在加热部分(5)中通过炉腔(17),所述炉腔至少部分由绝缘且不导电的金属制成, 同时通过横向磁通感应加热元件(15,16)通过横向磁通感应加热(TFIH)加热,所述横向磁通感应加热元件(15,16)位于包含保护性非氧化气体或气体混合物的所述室外部。 本发明的特征在于,所述金属物体是不锈钢物体,所述不锈钢物体已被冷轧成具有高度反射性的表面,所述冷轧不锈钢物体通过所述炉腔并在所述腔室中被加热到加工 温度为700-1200℃,冷轧的不锈钢物体在700-1200℃的温度下保持足够长的时间,以使钢完全再结晶,然后热处理的金属物体直接从 在非氧化性气体通过的气密冷却部分(6,27)中的处理温度降至600℃以下
