For 50 years VELCO GmbH/Germany has been building a solid reputation as a reliable partner of the foundry, steel and refractory industries.

It started in 1971, when VELCO was established by Kurt Wolf, father of the today’s owner Christian Wolf, in the city of Velbert located at the border of the Ruhr industrial area. This town formerly was an important center of the foundry industry. And so the first rotor gunning machine of type Rotamat was launched in 1971 for this branch of industry. Still today this machine type is built and nearly 1300 Rotamat machines are in use all over the world.

During the decades VELCO improved and broadened its machine technique, respecting industry’s demand for cost savings, improved efficiency and rising safety importance. Besides the rotor gunning machine VELCO’s delivery program now comprises also pressure vessel gunning machines and gunning robots for the refractory repair of the different aggregates.

Based on the know-how of this machinery and its use in steel plants VELCO built up a second business line; the pneumatic transport of dry bulk materials. In steel plants this is mainly the injection of carbon or lime for slag foaming in the EAF.

Project highlights are a pneumatic transport line of 1000 m distance and approvals for different ATEX zones. Lowest achieved feed rate for an application was 20 g/h highest was up to 500 kg/min.

As environmental demands became more important VELCO used its know how for developing equipment for pneumatic transport of filter dusts and other residues for injection into furnaces.
