Pusher synchronism control
Customer type
- Steel industry
Application
Profile pusher in furnace
Specifications
The customer contacts us so that we can propose an alternative solution to the existing synchronism system, based on a rotary flow divider, according to the weight distribution the synchronism error between the 2 pusher cylinders exceeded 25mm, deforming profiles and making them useless for commercialization.
Proposal
Synchronism system based on 2 servo-performance proportional valves EATON AXISPRO and a closed loop controller DELTA MOTION RMC75P, with Profibus communication. Existing cylinders, their position sensors and other valves are used.
Result
System with higher productivity and reliability, with a synchronism error of less than 1mm along the entire 1,500mm stroke and continuous monitoring of the operation, integrating our controller into the customer’s control system. The picture shows 4 curves: the position targets for each of the 2 cylinders and their actual position.
Installation in a short maintenance shutdown, with start-up and adjustments in half a day.
