HORN Glass: Hot repair at HEINZ-GLAS in Piesau

HORN Glass' subsidiary hot repairs glass melting furnace

With a family glassmaking tradition dating back to 1523, the HEINZ-GLAS company is today one of the world´s leading manufacturers and finishers of glass flacons and caps for the perfume and cosmetics industry.

HORN Bau & Service GmbH, a subsidiary of HORN Glass Industries AG, was contracted for the hot repair of the glass melting furnace at HEINZ-GLAS in Piesau, Germany. Here, the entire 250 tonnes per day glass melting furnace was drained to carry out repairs at the doghouse and the throat.

To avoid consequential damage, the furnace temperature was kept at 1200 degrees Celsius. At these temperatures, the service experts started to remove the remaining doghouse palisades and plating in this area as well as in the throat.

As a next step, new doghouse palisades and corners were replaced and various critical areas were re-plated. Continuous endoscopies were carried out during the repair process to assess the extent of the repair and to ensure HORN’s own quality standards.

After fill up by HORN, the furnace was successfully put back into operation after a few days. Parallel to this work, the complete colouring forehearth was reinstalled and heated up by HORN.
