SGGT Hydraulik is currently installing a new Microline Descaling MD1500 D descaling system in the Bockenau/Germany plant of Musashi Europe GmbH for descaling of large-format, rotationally symmetrical forgings for cars and trucks.
The system works with a maximum water quantity of 1.5 l per part and thus achieves a temperature drop of only 10 °C even with small parts.
In combination with innovative conveyor and control technology, which takes over the entire process handling including the press quiver feeding, it descales up to 1,200 parts per hour.
Since the process pressure in the water circuit is only generated when it is needed, the system is exceptionally high in energy efficiency: With a drive power of just 22 kW, the hydraulic power compares to 115 kW.
The process water is recirculated in a closed circuit, taking care for scale separation, its disposal and filtration. A special feature, developed for the Microline Descaling, is the physical separation of process water and ultra-fine scale with particle sizes of less than 5 µm, which cannot be adequately separated by conventional filtration technology.
The system is currently being installed between the induction heater and the new “MT 5000”; eccentric forging press and is expected to start up operations in summer 2020.
