**LCC vs ULCC castables:** Low cement castables (LCC) contain 4–8% CaO, bulk density
2.7–3.0 g/cc, apparent porosity 8–14% — the workhorse for steel ladle working linings and
tundish covers. Ultra low cement castables (ULCC) contain under 1% CaO, hot MOR 12–18 MPa at
1400°C — specified for ladle impact pads and torpedo car wear zones. Both require disciplined
dry-out (25°C/hr with holds at 110°C, 350°C, 600°C) to avoid explosive spalling.

**MgO-C / magnesia-carbon bricks for BOF and EAF:** 74–90% MgO with 8–20% graphite and
metallic antioxidants (Al, Si, B₄C). Carbon level matched to duty: 8–10% for the metal line and
general lining, 14–18% for the slag line.

**Acid proofing systems:** Acid-proof brick (IS 4860) protects to 300°C; acid-resistant tiles
to 120°C. Potassium-/sodium-silicate cement joints (>96% acid resistance) handle concentrated
H₂SO₄, HCl, HNO₃. Carbon bricks (>90% C) specified for hydrofluoric acid and strong alkalis.

**EAF refractories for the green steel transition:** EAF steelmaking is ~30% of global
production today, projected to exceed 50% by 2035 (World Steel Association short range outlook).
India's EAF capacity is expanding at roughly 4–5% CAGR with 20+ million tonnes of announced
capacity by 2030, concentrated in the Odisha–Jharkhand–Chhattisgarh sponge iron corridor.

**Refractory consumption benchmark:** Steel production consumes roughly 60–70% of world
refractory output; modern steel plants use about 8–15 kg of refractories per tonne of crude
steel produced.
