All-electric furnace rebuilt for German crystal specialist

F X Nachtmann has been producing hand- and machine-made goblets and gift articles since 1834. The company, which now has over 1200 employees and a turnover of around €80 million in 2018, offers the finest crystal glass from Bavaria, with all kinds of drinking glasses, vases, plates etc being part of the extravagant range.

In October 2019, HORN received an order to construct furnace two for the plant in Weiden, an all-electric furnace with seven production lines, which produces up to 25 tonnes of tableware per day.

The melting furnace represents a special feature, as the heating is carried out electrically by means of  tin oxide electrodes, as well as by means of an oxygen gas mixture.

The distributor and the forehearth were previously electrically-heated and have now been converted to the pure HORN CORA gas mixture heating.

HORN's scope of supply included the planning of the refractory requirement for the distributor and forehearths and the refractory structure of the melting furnace, distributor and forehearths.

Furthermore, the steel superstructure bracing and accessible platforms were planned, manufactured and erected. For the distributor as well as forehearths, the HORN  gas-air-mixture heating system CORA was planned, manufactured and installed, as well as a combustion air supply.

Furthermore, the whole plant was equipped with a measuring and control station and to simplify the control, the SCADA process control system developed by HORN including hardware and software was integrated.
