Melt-Holding Vessels TRIZ Cases

Rotating permanent magnets induce eddy currents in molten aluminum to drive fluid flow, reducing macrosegregation and oxide defects.

An immersion heater uses a heat-resistant outer cover to protect internal heating elements from corrosive molten metal.

Multi-part nozzle design manages thermal expansion through segmented refractory blocks and sealing elements.

Oval cross-section distribution duct dissipates flow energy to calm melt turbulence and stabilize the meniscus during steel casting.

A sliding gate device uses a contact pressure control mechanism to maintain sealing force between plates.

Segmented crossbars move independently to lift ladles, reducing energy consumption and maintenance time.

A tube exchange device applies transverse clamping force to secure a pouring nozzle within a casting frame.

Segmented immersion nozzle design eliminates neck regions, preventing crack formation from thermal stress concentration in continuous steel casting.

A pourable silicate and ester mixture hardens in situ to form a solid refractory lining.
