Krosno Glass SA, one of Poland’s premiere makers of exclusive glassware, has selected Forglass again to perform upgrades on one of its main furnaces. The work, planned for November 2020, will include partial replacement of refractories, heat-up, fill-up and hot sealing.

Making extensive use of computer modelling, Forglass has also prepared the design of a forehearth that the customer has requested for a future upgrade. Krosno’s high end glassware products require the delivery of molten glass with very strict parameters of not only chemical composition but also extreme uniformity of temperature.

To achieve this uniformity, Forglass has designed the forehearth with two rows of burners, with the upper row capable of both heating and cooling functions (by delivering pure air).

Additionally, the forehearth will feature ceramic stirrers positioned strategically along the path of glass flow.

All of the functions of this atypical forehearth are controlled automatically by customised software, also designed by Forglass.
