Hauhinco has been contracted by a customer to engineer a descaling system for a new rolling mill for stainless steel panels. The new descaling system should reach the best power and energy efficiency combination for the current requirements but should also have enough reserves for future work piece sizes.
Hauhinco mastered this challenge through an indirect drive solution
consisting of a redundant high pressure pump system and a high pressure
accumulator system. As a drive station, two EHP-3K200 high pressure
plunger pumps with a reduced input speed are used. By these measures a
continuous pump operation for the current conditions is reached on the
one hand and on the other hand enough power reserves for future
enhancements are given. The automatization solution is specifically
designed for the system and includes a typical charging mode of the high
pressure accumulator system in correlation with the storage level,
however also allows a decrease and increase of the pressure level
through parallel controls of the compressor and high pressure pump. With
regards to valve technology, Hauhinco uses the metal seat technology
which has been proven in water hydraulics for decades. The valves use a
wear resistant sealing system consisting of a special PU-compound, which
has less seal friction and thus less heat development.
Besides the delivery of the mentioned products, Hauhinco supports the partner from the nozzle design and the performance calculations up to the commissioning including the integration of external delivery scopes. The support during the first days of operation after the commission guarantees the customer a sustainable optimization of the production.
