HOT-DIP COATING INSTALLATION

摘要

The invention relates to a hot-dip coating installation for coating a strip with a liquid metal. A roll embodied as a hollow body is provided in the liquid metal for deflecting or stabilising the strip. The roll is mounted in a bearing on a carrier arm of the hot-dip coating installation by means of a journal. The aim of the invention is to reduce the rotational resistance, the angular momentum and the slip incline of the roll in relation to the strip. To this end, the inside of the roll is sealed against the liquid metal and a channel is provided for connecting the inside of the roll to the spatial area on the periphery of the roll journal. In this way, an excess pressure inside the roll and therefore an unwanted deformation of the roll are prevented.
