High temperatures and variable loads on rolling mills, continuous casting, blowers and crane systems.
In steelmaking, equipment works under high temperature, impact loading and scale. Rolling stand bearings produce signals that are hard to judge by classic trending because of the variable load.
EVAM evaluated vibration analysis and rule-based evaluation (RBE) are particularly valuable here: measurements are normalised against machine speed and load so that they become comparable.
Ready-made package solutions that not only monitor critical equipment but keep it running at its most efficient operating point.
We collect vibration and shock pulse data from your rotating equipment on site and interpret it through spectrum, time waveform and envelope analysis. We report bearing, gear, unbalance, misalignment, looseness and resonance faults together with their root cause.
We balance fans, impellers, rotors, crusher rotors and similar rotating parts in place, at operating speed and in their own bearings. Single and dual plane balancing is performed to ISO 21940 (formerly ISO 1940) tolerance grades.
We align coupled machine trains such as motor-pump and motor-gearbox sets with a laser system. Soft-foot checking, thermal growth compensation and precut shims deliver a lasting result.
