Rolls TRIZ Cases

A felt-faced composite stripper removes cooling fluid from roll surfaces, improving sealing and preserving lubricant on rolling stock.

Solid-jet lower nozzles cut through coolant pools while flat-jet spray bars spread flow evenly for more uniform upper work roll cooling.

A compressible polyurethane-coated folding roller adapts the nip to changing signature thickness, avoiding manual adjustment and fold defects.

Specific Ca and rare earth additions let magnesium alloys keep conventional rolling productivity while improving room-temperature formability and corrosion resistance.

Full-jet nozzles keep coolant streams concentrated, cooling roll stands effectively at lower pressure with less energy use and nozzle wear.

A reverse-directed liquid curtain wipes strip or roll surfaces without contact, blocking roll gap leakage and reducing scraper wear.

Internal coolant channels and inward sealed bearings protect continuous casting roll mantles from heat, humidity, and contamination to extend service life.

Ca and Gd tuned Mg-RE alloy composition enables conventional rolling while improving room-temperature formability, strength, ductility, and corrosion resistance.

Axial cooling channels and integrated distributor rings cool the press roller bandage evenly, cutting wear, maintenance, and overheating.

Two-stage rolling preforms the pipe surface before final threading, cutting non-roundness while preserving zinc coating and boosting yield.

A form-fit rotary engagement transfers ram rotation and pressure directly to the roller, enabling compact, precise sheet forming across varying thicknesses.

Vertical splits in rolling disperse Mn segregation across H-shaped steel flanges, improving fillet toughness without heat treatment.

Profiled-roll indentations create high-strength zones in ductile austenitic steel, improving elongation, fatigue resistance, and thickness use.

A water-jet pump removes coolant pooled at the upper work roll wiper, preventing overflow, protecting strip edges, and allowing wider strip rolling.

An intermediate Fe-alloy layer controls solidification in centrifugally cast rolls, preventing boundary shrinkage voids and extending roll life.

Fe-based binder chemistry and fast cooling create bainite or martensite cemented carbide that resists dents and extends roll life in cold rolling.

Transferred MC carbides harden inner-layer shaft portions, extending composite roll life without sacrificing graphite cast iron toughness.

Pre-applying additive lubricant at a set distance before the rolling gap improves adhesion, lowers friction, and supports higher strength rolling.

A compressible elastic roller coating adapts the effective gap to varying signature thickness, maintaining fold quality without manual adjustment.

Carrier-gas lubricant and water-based cooling cut rolling fluid use while preserving thickness reduction, skin pass quality, and material toughness.

Electron beam welded journals let large HIP composite rolls keep a wear-resistant working layer while limiting base-body thermal stress.

Frustum-profile mill rolls use axial shifting to offset wear, prevent edge contact, and extend ESP rolling campaigns while holding thickness.
