# Foundry pouring spouts

They direct the flow of molten metal into molds, preventing spills and losses.

Family: Metallurgical applications

## Processes
- Liquid-metal conduction
- Casting distribution

## Challenges
- Flow erosion
- Thermal leaks
- Metal contamination

## Advantages
- Thermal shock resistance
- Machined geometries
- Lower sticking than many refractories

## Limitations
- Erosion wear
- Grade selection by metal
- Service life depends on cycles
