Process Efficiency Improvement TRIZ Cases

Selective stripping with nitrobenzene derivative, ethylenediamine, and ammonia removes Ni plating while preserving magnet properties.

Alternating laser irradiation directions curb stress variation from absorber thickness changes, producing more uniform compressive residual stress.

Real-time sulfuric acid flow adjustment keeps laterite nickel leaching at the optimal acid-to-ore ratio, improving efficiency and lowering cost.

Superheated twin-roll casting with controlled Si and C preserves θ-fiber texture and magnetic properties in thin electrical steel strip.

Low final cold reduction and optional inter-annealing balance alpha and beta fibers to reduce anisotropy, roping, earing, and spoilage.

Continuous casting and annealing keep recycled-can aluminum within target chemistry, delivering strong, low-earing sheet for drawn and ironed cans.

Recycled aluminum pellets with carbon compounds cut deoxidizer cost and energy use while avoiding organic pollutant generation in steelmaking.

Controlled alloy chemistry and heat treatment turn recycled aluminum scrap into formable sheet with spherical intermetallics and strong ductility.

Multi-direction laser spot expansion reduces residual stress variation along a target surface area during laser peening.

Increasing moving average laser intensity during spot scanning curbs residual stress variation and keeps surface treatment more uniform.

A two-stage cold rolling route with optional inter-annealing balances alpha and beta fibers to reduce anisotropy and improve sheet formability.
