SORG: 50 electric years – 50 furnace facts – VI week

In the sixth week of its 50 furnace facts series SORG tells a few things you may or may not already know about the Vertical Super Melter® itself

SORG continues its 50 furnace facts series, with a few things you may or may not already know about the Vertical Super Melter® itself.

From the origins of SORG’s very first all-electric melter, to the many clever features that make it the most energy-efficient, eco-friendly technology currently available. As well as some interesting facts and figures to back it all up.

Smart from top to bottom – Week Six
By turning the design of furnace electrodes on its head, Sorg has made the whole melting process a lot quicker and easier, saving on wear and tear, as well as valuable downtime for inspections and repairs.

Fact 34
Specially developed SORG Top Electrodes are used for all VSM® furnaces.

Fact 35
Top Electrodes are inserted through the furnace superstructure and enter the glass bath through the batch layer.

Fact 36
Top Electrodes do not require holes or water-cooling in the furnace side wall like conventional horizontal electrodes. Therefore, the convection currents produced around the electrodes cause less wear on the refractory material.

Fact 37
Top Electrodes can be swung out of the furnace for inspection and exchange.

Fact 38
An exchange of a single electrode takes a two-man team 15 to 20 minutes.
