SLM-1000 High-Strength Nano Insulation Board
1000 °C high-strength nano insulation board for steel ladles, tundishes and industrial kiln walls. 30–50 % energy saving, vacuum-packed for export. — Suleiman Refractory.
SLM-1000 High-Strength Nano Insulation Board is a next-generation microporous insulation panel engineered by Nantong Suleiman Refractory Co., Ltd. for service temperatures up to 1000 °C. It is widely used in steel ladle and tundish linings, petrochemical crackers, ceramic kiln walls, and industrial furnace backing, replacing traditional calcium silicate and ceramic-fiber boards.
Why SLM-1000
- Ultra-low thermal conductivity — 0.024 W/m·K at 600 °C, cutting shell heat loss by 30–50 %.
- Lightweight & high compressive strength — density 280–320 kg/m³ with ≥ 0.6 MPa cold-crushing strength, accepts anchor welding and machining.
- Clean, fiber-free — no respirable crystalline silica; safer handling than traditional boards.
- Export-ready vacuum pack — foil-sealed and palletized, saving ~40 % container volume.
