AI Technical Summary

Technical Problem

Existing rolling mill technologies face inefficiencies in lubricant removal, leading to contamination and surface damage of laminated strips, particularly stainless steel belts, due to imperfect wringing and rapid roller wear.

Method used

A spin-drying process using hydrodynamic pads that slide on a fluid layer to perform initial wringing without contact, followed by suction and optional fluid injection and projection to ensure complete lubricant removal, minimizing contact and wear.

Benefits of technology

The process effectively removes lubricant without surface damage, maintaining the strip's finish and reducing roller wear, ensuring readiness for subsequent industrial processes.

Abstract

TITLE: WRINGING METHOD AND WRINGING INSTALLATION The invention relates to a method for wringing a rolled strip, the method comprising: / A / Providing a wringing installation comprising two hydrodynamic pads, extending lengthwise over a width of the rolled strip, / B / Advancing said rolled strip between two hydrodynamic pads in a defined direction of advance from upstream to downstream, / C / Applying pressure to the hydrodynamic pads, one towards the other, on either side of the rolled strip, along a clamping plane transverse to the strip, during the advance of said rolled strip, the hydrodynamic pads sliding on the rolled strip by means of a layer of fluid, each of the hydrodynamic pads performing a first wringing operation by blocking at least a part of a lubricant layer of the strip coming from upstream to downstream, / D / Aspiration,through a suction orifice located downstream of the hydrodynamic pads, at least part of a residual layer of fluid is removed, thus performing a second wringing operation on the belt. The invention also relates to an associated wringing installation. Figure 3,
