Furnace rolls and conveyor rollers for metallurgy and mechanical engineering

ENCE GmbH company offers and is ready to deliver the following rolls or their separate components (such as roll barrels and journals) separately:

  • Furnace rolls

Furnace rolls are key components in furnace roll tables used in continuous heating and thermal furnaces, including roller-hearth furnaces in metallurgy.

Heat-resistant rollers with a diameter of 50 mm to 2000 mm, which are made of high-alloy with chromium Cr and nickel Ni are usually cast by centrifugal casting.

Furnace rolls Furnace rolls
  • Conveyor rollers

Conveyor rollers are of cylindrical shape and rotate on ball bearings on fixed axles. Conveyor roller shells are usually made of a steel pipe

Conveyor rollers Conveyor rollers

Conveyor rollers are delivered with outer diameter of 41 mm and roller length up to 2600 mm in various axle edge designs at the customer’s discretion. Bearing assemble case has two versions: turned, for heavy operation conditions, and made of steel sheet by pressing for moderate to light-duty operation conditions; as a result, this case has lower weight than turned one.

Custom made couplings

We offer you to consider the following, as an example of an individual approach to the customer problems from the part of the specialists of ENCE GmbH (ЭНЦЕ ГмбХ) company.

Centrifugal compressors, K-890-121-1 model, with gear couplings, have been in operation at the enterprise. During operation, surfaces of teeth and couplings were permanently affected by severe pitting corrosion; also, seasonal temperature variations have resulted in misalignment and high vibration in compressor’s assemblies. ENCE GmbH (ЭНЦЕ ГмбХ) company specialists have replaced gear couplings by the newly designed plate couplings; as a result, all problems were resolved, and the equipment operation was stabilized.
