BEARING ARRANGEMENT FOR A DEFLECTION OR GUIDE ROLLER IMMERSEDLY ARRANGED IN A MOLTEN METAL BATH

摘要

The invention relates to a bearing arrangement for a deflection or guide roller (1) which is immersedly arranged in a molten metal bath (1) for a metal strip that is to be coated and which is rotatably arranged on roller carrying arms (3) by means of bearings (9). The bearings (9) are sealed off from the molten metal bath by means of at least one induction coil (25) which surrounds an axis (5), shaft or lifting lug associated with the deflection or guide roller (1) and which defines an annular sealing gap (32). In order efficiently seal the bearings against penetration of molten metal yet to avoid subjecting the bearings (9) to excessive thermal stress (9), a sheath (33) made of a ceramic material is arranged inside the sealing gap (32) at a distance to the induction coil (25).
