Charge Composition/State TRIZ Cases

Sulfurization fuming and electric settling recover tin and precious metals from hazardous tin smelting intermediates while avoiding discounted waste sales.

Aligned electrodes measure molten bath resistivity in real time, replacing delayed manual copper sampling in smelting furnaces.

Matrix-adjustable blow zones tune air pressure and electric current to address coated-glass heating differences, shorten heating time, and limit bending.

A cylindrical shell, circumferential airflow, and guide members improve heat exchange while reducing heater size and complexity.

Vibrating cleaning elements retract during discharge to prevent contamination, maintaining seal integrity and reducing downtime.

Using hot recycle gas as propellant eliminates nitrogen consumption and prevents condensation in pneumatic ore charging systems.

Opposed lances inject solid feed materials into a molten bath to create overlapping plumes that agitate the liquid metal.

Segmented induction coils in a vertical furnace heat oily solid waste, resolving uneven temperature distribution and energy waste.

Decarburization section in ceramsite kilns recovers heat from raw material combustion, reducing energy consumption and improving thermal efficiency.

A tiltable hood-like housing with a gas-tight flue gas removal system captures emissions during metal melting.

Localized contact joule heating sinters ceramic coatings above 1000°C while keeping the substrate bulk cool to prevent thermal stress damage.

Flexible compensating elements decouple bearing assemblies from housing walls, reducing thermal stress and extending service life.

A flow measurement system with differential-pressure sensors monitors operating atmosphere velocities between fiber carpets in an oxidation furnace.

Staged post-combustion via internal shaft injection recovers exhaust gas heat while minimizing iron oxidation in continuous steel production.
