Magnesia-carbon brick is the core working-lining route for many converter, ladle, EAF, and refining positions. HANHENG’s route is built on fused or sintered magnesia, flake graphite, resin bonding, and antioxidant additions, which is why it remains the standard choice where slag attack, thermal shock, and hot strength have to be handled at the same time.

Alumina-magnesia-carbon brick is widely used in steel ladle walls, bottoms, and coordinated working-lining positions where system balance is more important than pushing every area to slag-line severity. It is a practical route for buyers who need the full ladle to run as a stable lining system rather than as one aggressive brick family used everywhere.

Magnesia checker brick is used in regenerator and thermal-storage structures where heat retention, dimensional stability, and long-term cycling behavior are critical. Buyers evaluate this route on operating efficiency over time, not on one-off high-temperature claims.

Magnesia-chrome brick remains necessary for selected severe-duty furnace sections where corrosion resistance, hot strength, and microstructural stability need to be reviewed more precisely. HANHENG’s product system covers four practical route levels: common, direct-bonded, rebonded, and semi-rebonded.
