Göteborg – Swedish fastener manufacturer BULTEN has commissioned the Austrian heat treatment specialist AICHELIN with the production of a cast link belt furnace for the refinement of high-strength steel screws and nuts. At 80 meters length, the furnace plant has a performance of 2 tons per hour and is scheduled to be shipped by December 2018. It is the second industrial furnace plant for the Swedish Hallstahammar site.
Ten years after its first delivery for this site, AICHELIN has now been able to land the follow-up order for a second 2000 kg/h cast link belt furnace plant. Thanks to the positive references at Bulten, the current project was finalized within a few months only between the first request and the final negotiation. The plant line measures 80 x 10 meters and weights around 180 tons; counting liquids and components, even 230 tons.
AICHELIN is delivering the electrically heated high-temperature hardening furnace and the protective-gas-tight tempering furnace with oil or emulsion hardening baths. Moreover, measuring and switching systems are included, as well as the process control system FOCOS 4.0 for the new plant (as well as an update of the data acquisition of the existing plant) and a protective gas generator. As with the previous order, the customer provides the loading and unloading device and the component washing machines under their own direction.
