Work Cleaning Devices TRIZ Cases

A learned prediction model estimates post-rolling shape and adjusts cold rolling conditions to keep sheet crown stable at high productivity.

Parallel slot-nozzle guide surfaces keep coolant exit geometry stable under wear, enabling even work roll cooling without runoff onto rolled material.

Multiple shallow pits with dredging separate coarse and fine scale from process water, cutting civil works, maintenance, and build time.

Counterflow liquid spraying between tandem mill stands removes metal particles before embedment, improving cold-rolled surface quality.

Reverse-direction fluid spray between tandem mill stands removes metal particles and emulsion residues before they are rolled into the strip.

A slit nozzle with controlled gap, angle, and pressure removes liquid from steel sheets while avoiding wringer rolls, dryers, and unstable air suction.

A liquid-curtain nozzle array wipes coolant from moving strip or roll surfaces without contact, preventing lubricant mixing, wear, and leakage.

A downstream-to-upstream gas jet strips liquid from moving steel sheets, while gap measurement keeps removal effective without wringer rolls or dryers.

High-pressure abrasive slurry jets clean steel sheets and adjust surface roughness, replacing complex skin-pass processes.

Staggered rollers on parallel axes distribute pressure continuously across the strip width, preventing localized marking caused by single-axis bearing blocks.
