Glass Melt Furnaces

Glass Melt Furnaces

Not every furnace is suitable for glass melting. Glasses often have corrosive compositions whose fumes and splatter can attack fiberboard furnace linings and heating elements. You don’t want a furnace whose interior resembles the face of the moon; you don’t want the protective coating on the molydisilicide heating elements literally running down the element and dripping onto the load platform. Another potential problem that could occur is a molten glass breakout, which can lead to unplanned downtime and costly repairs.

Deltech Glass Melt Furnaces

Deltech glass melt furnaces will perform under the most rigorous environmental and cycling conditions. They were initially designed for use in national lab research setting in which the furnaces were continuously used and operated with many glass formulations. Today these furnaces are widely used in universities, government labs, and industrial settings for the research and development of bio, optical, nuclear waste containment, and other specialty glasses.

Key Benefits of Deltech’s Glass Melt Furnaces

Deltech’s glass furnace models boast a range of benefits to support your glass melting requirements. These lead to high-quality products, improved glass production and safer operations. The furnaces operate at temperatures of up to 1800 degrees Celsius and are fitted with a ceramic lining to resist glass attack. Our glass melt furnaces are designed to be idled at high temperature and to allow rapid dropping of the bottom for fast quenching.  The high thermal mass of the hot zone provides quick recovery from the quenching application.  A ceramic split plug and ceramic top cylinder allow easy access for a stir rod while protecting the furnace roof and top opening from corrosive elements.

There is also a range of optional features that can be recommended to you or that you can select. Deltech’s optional glass furnace features include:

  • Automated features such as melt pours
  • Drain plugs to support cooling
  • Element protection liners
  • Spill traps in place of hearth plates to contain small glass spills
  • Kiln cars
  • Sight ports
  • Manual or programmable stirring mechanisms for glass fining
  • “Atmosphere envelope” designs for applications requiring processing in inert atmospheres

Glass melt furnaces can be provided as they are manufactured, we can customize them to suit your requirements, or work with you to create a unique design suited to your unique application.  Contact us today for more information.
