STEBGUT – Furnace roller

Initial situation:

• The heating of fine plates for hot-dip galvanizing and / or heat treatment takes place in continuous furnaces.
• The plates are transported through the furnaces using metal good transport rollers.
• The high furnace room temperatures of approx. 1,300 ° C. now require water cooling of these rollers.
• This results in cooling losses of approx. 300 kW per roll.

Working topics:

• Exact measurement-technical recording of the operating conditions of current good transport rollers.
• Development of a new material transport on the basis of further developed materials.
• Experimental investigation of the new transport role in the pilot plant.
• Operational testing of the new material transport roller at two continuous furnaces in production operation.

Results:

• Energy savings of 10-20% by reducing the energy-intensive water cooling of the material transport rollers.
• Ensuring the surface qualities and strength of the steels by means of further developed high-temperature steels.
