Metal plate rolling equipment manufacturer

In the field of metal plate rolling equipment ,thickness accuracy directly determines product quality and performance.Whether it is automotive steel plates,aviation aluminum materials,or electronic copper foils,a thickness deviation exceeding±0.01mm may lead to product failure.Therefore,manufacturers of metal plate rolling equipment manufacturer to introduce intelligent sensors and high-precision actuators to achieve thickness control.
1.Rolling mill stiffness and dynamic compensation technology
The vertical stiffness of the rolling mill is increased to 1500kN/mm by using a prestressed frame structure and high-strength alloy cast steel,which is 40%higher than traditional rolling mills and reduces thickness deviation caused by rolling force fluctuations.By using finite element simulation and laser displacement sensors to monitor the bending deformation of the rolling mill in real time,reverse hydraulic prestress is applied to the rolling mill bearing seat to reduce the lateral thickness fluctuation of the 2000mm wide plate to within±2μm.
2.Millisecond level response of hydraulic servo system
Manufacturers of metal plate rolling equipment manufacturer use 35MPa grade electro-hydraulic servo valves,combined with nanoscale polishing hydraulic cylinder inner walls,to shorten the response time of the pressing system to 8ms and achieve thickness transient compensation during sudden changes in rolling force.
3.Roller system accuracy and thermal deformation control
This product uses an online electrolytic dressing grinder to machine the surface roughness of the work roll to Ra≤0.01μm and the cylindricity error≤1μm/m,eliminating periodic thickness fluctuations caused by roll surface morphology;Embedding semiconductor refrigeration chips and fiber Bragg grating temperature measurement networks in roller bearings,shafts,and other parts to control the temperature gradient of the roller system within±1℃and avoid thickness drift caused by thermal expansion.
The goal of sheet thickness control for metal rolling equipment manufacturers is to achieve the coupling of"force heat shape"at the atomic scale.Continuously breaking through from three dimensions of metal plate rolling equipment manufacturer,multi physics field coupling modeling,and intelligent algorithm engineering,we aim to build a collaborative innovation system of"millimeter level equipment accuracy,micrometer level process control,and nanometer level quality perception".
