Walking beam furnaces have traditionally been used for very heavy applications in steel mills for re-heating billets and blooms for in some cases throughputs of 400 tons per hour.

Prestige Thermal Equipment have, based on this principle, developed units that can provide a processing capability from a few kilograms to many tons utilising the walking beam principle.

The main advantage of the walking beam is that once the furnace is at temperature the material transmission device requires no further energy thus all energy available in the furnace is committed to the product. With this system we have, in some cases, reduced the clients operational costs by way of doubling the throughput and halving the energy input when compared to alternative transmission systems.

Eleven such walking beam furnaces have been supplied within a period of 2 years by Prestige Thermal Equipment. Applications ranging from hardening and tempering, normalising, heating prior to forming and annealing.

If you need to heat process ceramics, metals or glass in various ways and require flexible production schedules, or different cycles to different temperatures, then a Prestige Thermal Equipment's Walking Beam Oven may be the best choice for your application.

Today, cycle flexibility is often essential for successfully achieving high productivity, better quality and low cost. That's why so many Prestige Thermal Equipment Drying Ovens are specified and routinely used for production at temperatures from 80°C up to 700°C with a temperature uniformity from ± 5°C.

Models are available in a wide selection of sizes from 1 m to over 28 m capacity. In addition, Prestige Thermal Equipment offers a Gas Fired Modular System concept which features an easily expandable design that can grow as your needs increase.

Standard units have programmable microprocessor based controls and strategically positioned high velocity excess air burners to regulate heat input that surrounds and penetrates the load to provide close temperature control and uniformity.

An energy efficient, low thermal mass, end stack fibre module lining allows for rapid heating and cooling. This is especially important when production needs are variable, and range from dense, tightly packed small items to large, heavy parts which require complicated heating schedules or quick turnaround.
