The blast furnace is the core ironmaking unit; linings face 1100–1500°C heat, slag/metal attack and alkali damage, with long campaigns relying on hearth ceramic cups and bosh cooling staves.
View Problems & Solutions →The hot metal ladle transports and holds molten iron; its bottom suffers impact and its slag line suffers slag attack, making it one of the most frequently relined refractory zones.
View Problems & Solutions →The hot blast stove preheats blast air to 1150–1300°C via checker bricks; checker service life and hot-blast main lining integrity determine achievable wind temperatures.
View Problems & Solutions →The iron runner guides blast-furnace hot metal to ladles; its slag line endures alternating metal/slag scouring, with Al2O3-SiC-C castable throughput being the key metric.
