Transport rollers are used in steel mills with annealing lines for cold-rolled stainless steel strip to transport the goods through the annealing furnace. These come into direct contact with the glowing steel strip and guarantee a high-quality strip surface. The isoplan® STEEL ROLLER product range is specifically designed for these high temperature and quality requirements in the steel industry. The conventionally water-cooled steel core of the transport roller has excellent thermal insulation when equipped with isoplan® rings, which saves a great degree of heating energy of the furnace.
