Melt-Holding Vessels TRIZ Cases

A dual-port valve uses vacuum suction for hose retraction while sealing the unused port and supplying grounding, power, and debris protection.

Breaker blades on the central draw valve agitate packed ice crystals, preventing passageway clogs during simultaneous two-flavor dispensing.

Controlled angular repositioning lets a ladle shroud reuse multiple preset orientations, spreading internal wear and extending casting life.

Rotating a ladle tube to three set angular positions spreads thermal and mechanical wear, extending service life in liquid metal casting.

A conductive shield captures heat-induced leakage current and returns it through neutral, preventing nuisance GFCI trips in heated components.

A conductive shield intercepts leakage from heated components and returns it to the GFCI neutral path to prevent nuisance trips.

Top-down die heating and precise electromagnetic pump pressure improve rotor aluminum feeding, reducing pores and shrinkage while boosting throughput.

Controlled chromium addition and magnetic-field casting reduce segregation, converter contamination, and press roll manufacturing cost.

Using a stainless steel converter, this case shows how controlled Cr addition and magnetic solidification reduce segregation, cracks, and cost.

A modular cutter with radial and circumferential members breaks hardened steel residue in furnace tapholes to keep liquid steel flowing.

A Cu-based sliding layer uses coarse Bi near the surface and finer Bi near the base to improve seizure resistance without sacrificing fatigue life.

Rapid twin-roll casting and single-stand rolling turn 100% scrap steel into ultra-thin strip while suppressing grain boundary segregation.

A piston-driven sleeve and locking balls secure plate alignment without hydraulic locking circuits, improving stability and lowering system complexity.

Electromagnetic stirring and optimized temperature control improve semi-solid slurry uniformity while reducing contamination, defects, and process instability.

Position deviation correction and automatic holding keep tundish lifting cylinders synchronized despite leakage, uneven load, and component variation.

Coarse Bi near the sliding surface and finer Bi near the base help a Cu alloy member resist seizure while maintaining fatigue resistance.

A movable blocking member limits carriage stroke during casting and allows service overstroke, reducing liquid metal loss risk.

Locking balls, a shaft, and a pneumatic piston create secure plate coupling without continuous pressure, reducing hydraulic complexity and wear.

Rapid thin-strip casting and inline rolling use 100% scrap steel without pre-sorting, limiting segregation, cost, and process complexity.

Cryogenic cooling solidifies the melt pool at 100°C/s or more, enabling in-situ solution treatment of aluminum alloys with less distortion.

Defined torque on the carrier ring lets a robot replace sliding-closure discharge sleeves reliably despite tolerances and impurities.

Thermocouple-guided actuator control keeps the diffuser near the solidification front to reduce macrosegregation in continuous metal casting.

A moving electromagnetic stirrer and electroslag heating improve solidification in large ingots, reducing segregation, shrinkage, and mold sticking.

Temperature feedback and linear actuation keep the diffuser near the solidification front to reduce macrosegregation in continuous casting.

Automatic coupling and hydraulic locking let a molten metal sliding gate actuator be installed, fixed, unlocked, and removed with less casting downtime.

A heat-swelling seal closes gaps between sliding refractory elements, blocking air intake in metal casting nozzles without high clamping force.
