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. Here, the entire 250 t/d 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°C. At these temperatures, our 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.
We wish good glass at all times and look forward to further projects.
We would like to thank all the subcontractors involved, as well as HEINZ-GLAS in particular, for the always very pleasant collaboration and cooperation!
