Zeitzer Guss GmbH uses OTTO JUNKER melting equipment

Equipment technology Cast iron & steel

The successful company Silbitz Guss GmbH established a new foundry for the production of large hand-moulded castings of up to 30 metric tonnes unit weight in Zeitz, Germany. These castings are primarily used in the energy field (power stations/wind power plants). Only 20 km from the company's headquarters, an all-new foundry was erected on the premises of ZEMAG Zeitz, a former company with a very long tradition.

Solemn inauguration of the new foundry on 25th June 2009

The new 25-tonne furnace in action

The melting plant was ordered from OTTO JUNKER mid-2008 and successfully commissioned in April this year. The formal inauguration ceremony for the new foundry was solemnly conducted by the two managing directors, Dr. Wolfgang Maruschky and Dr. Frank Göttert, on June 25, 2009. Saxony-Anhalt's Minister-President, Professor Dr. Wolfgang Böhmer, pushed the starting button of the new furnace plant after the first pour had been initiated by Dr. Göttert following the tradition.

The foundry is equipped with a 25-tonne medium-frequency melting furnace plant. With its electrical power rating of 6,000 kW, the unit provides a melt output of 11.5 tonnes/hour. The furnace itself has a power consumption of 505 kWh/t at a melt temperature of 1,500 °C. The furnace features a back-tilting system and a deslagging spout to facilitate the slag removal operation. An additional slag gripper has likewise been integrated. Advanced exhaust hoods with bidirectional tilting action ensure a full extraction of furnace gases and dusts.

The weighing system supplies all data needed by the JOKS melting processor to control the power input and avoid overheating at any point of the process cycle. Our scope of delivery further comprised a longitudinally movable charging chute plus the entire water recooling system. The latter is equipped with separate systems for the furnace circuit and the switchgearcircuit. The furnace circuit has a glycol-free air-to-water cooler developed by OTTO JUNKER.
