# Blast furnace linings

Graphite blocks and parts for blast furnace lining: hearth, stack, bosh and sidewalls.

Family: Metallurgical applications

## Description
Blast-furnace linings need graphite with high thermal conductivity, low ash and good machinability in large formats. ESGRAF advises the grade by zone (hearth, stack, bosh, tuyeres) and thermal cycle.

## Processes
- Refractory lining
- Blast furnace

## Challenges
- Thermal shock
- Oxidation
- Wear from liquid metal

## Advantages
- High thermal conductivity
- Low ash in selected grades
- Machining of large blocks

## Limitations
- Service life depends on atmosphere and zone
- Requires drawing or block format
- Oxidation in air at high temperature
