Refractory liner for molten metal flow control valves, providing thermal insulation and erosion resistance in extreme temperature applications.
A refractory liner is a specialized component installed within molten metal flow control valves to withstand extreme temperatures (typically 1200-1600°C), chemical corrosion from molten metals, and mechanical erosion during metal transfer operations. It maintains valve structural integrity while preventing heat transfer to external components.

Typically 6-18 months depending on operating temperature, metal composition, and maintenance practices, with regular inspections recommended every 3 months.
Yes, specialized refractory patching materials can be applied for minor repairs, but significant damage usually requires complete liner replacement.
Proper expansion joints and installation gaps (typically 1-2% of dimensions) must be maintained to accommodate thermal expansion during heating cycles.
