Hydraulic system is a classic nonlinear system in rolling mill vibration system, but it often manifested weakly nonlinear. For high-precision position control mill vibration system, nonlinearity is also not negligible. Considering of strip hardening, elastic deformation of the work roll, non-linear friction, transfer delay of the strip, and ...
Prevent servo valve and pump failures caused by contamination related surface degradation. Applications include: Melt shop DC furnace. Automatic gauge control. Roll stand hydraulic system. Planetary & ring rolling, cold pilger mill. Caster & Oscillator. LMS hydraulics. Tundish gate.
The same hydraulic system also controls the side skirts, scrapers, and flaking rolls. Soaptec hydraulic three roll mills are equipped with a conveyor, located underneath the rolls, to collect the discarded soap. Pressurised coolant is pumped into each roll through the rotary coupling. The temperature is controlled by modulating valves.
The hydraulic system of the rolling mill is presented in Figure 1. Condition monitoring and diagnosis of a steel rolling mill requires a variety of measurement techniques.
