Machine Concepts specializes in the integration of air bearing shape roll technology to provide superior shape measurement and strip flatness.
Machine Concepts continually develops and implements air bearing shape roll technology to respond to increasing mill speeds, changing properties of metal and increasing demands for improved quality of strip flatness.
Thrust bearing featuring our exclusive wear resistant Hy-Comp composite material
The output signal of all rotors is measured before and after repairs on a Test Stub, Machine Concepts’ proprietary test fixture. These measurements quantify each rotor’s performance characteristics and are used to meet exact manufacturing dimensions. Complete inspection reports are provided to the customer with all repairs.
Infinite variable height retract mechanism (picture above)
The infinite variable height retract mechanism is equipped with a variable motor and machine screw jacks for adjusting the position of the shape meter assembly and hence the load on the rotors. The load control from the automation sets the height of the shape meter assembly based on the average rotor load into the pass-line of the strip while limiting the maximum rotor load. This gives maximum resolution possible for any strip thickness and metal properties.
Skewing device – illustration above (in blue)
The skewing device adjusts laterally to keep the strip perpendicular to the roll. The gear reducer motor is controlled by the mill automation through a signal from the thrust sensing bearings on each end of the rotor stack. This can be very beneficial for mills that have dual rewinds that are not exactly parallel, or a rewind that starts to droop from the weight of the coil.
