Major furnace repair completed !

During the annual holiday season, we managed to strip down & renew the entire hot zone of an old Ferro enameling furnace with 14 radiant tubes within 14 working days.

Below two pictures of respectively before and after the furnace repair.

Major furnace repair

Ditmer Trading & Consulting B.V. has received the order for a major furnace repair at a manufacturer of major appliances in the United Kingdom.

This repair will include the replacement of the radiant tubes, metal flue and insulation inside the hot zone of a Ferro GB enameling furnace.

See Ditmer Enameling Technology for more information about our services for the enameling industry.

Thermal imaging of enameling furnaces

The performance of industrial enameling furnaces may gradually decline over time.

This may result in higher energy consumption (read increased enameling cost) and reduced quality of the coated surface.

In extreme cases the enameling furnace may even unexpectedly break down, because insulation has been damaged and/or worn out.

Therefore we suggest regular inspections & thermal imaging to identify major heat bridges and other spots with possible insulation issues.

Enameling furnaces

Enameling furnaces

Curing or firing a porcelain (vitreous) enameling coating is done in high temperature enameling furnaces.

In the early days these enameling furnaces were made of refractory bricks, due to the required firing temperature between 800 and 850 degrees Celsius.

However, such bricks are sensitive for thermal shocks and need to be heated up & cooled down very slowly.

Therefore modern enameling furnaces are nowadays made of Low Thermal Mass insulation materials, like stone wool, vermiculite & ceramic fibers. Continue reading “Enameling furnaces”
