STEELFLEX® : TECHNICAL DATA SHEET - ENGLISH

Flexible microporous insulation panels up to 1000 °C

STEELFLEX® panels are specially designed for steel industry & other hot metal applications. The flexible microporous insulation panels have very good thermal and mechanical properties. The formulation is an opacified blend of filament reinforced pyrogenic silica (alumina for 1200 grade). The product range consists of three temperature grades, all available in different covering types. All coverings are water repellent to assure the stability of the microporous core when moisture might occur due to castables, mortar, …

STEELFLEX®-1000X has superior thermal conductivity values and can resist continuous temperatures up to 1000 °C.

STEELFLEX® panels can be shaped easily with a simple cutter and taped off with aluminium tape. The panels can be fixed in place with the same adhesives that are used for the refractory lining.

Typical applications
< #Back#
Microporous insulation offers an extremely low thermal conductivity, close to the lowest theoretically possible at high temperatures. Microporous materials are the preferred choice when a large temperature reduction is required within a limited space, or when strict heat loss or surface temperature requirements are specified.

  • Ladles
  • Torpedo cars
  • Tundish
  • EAF (Electric Arc Furnace)
  • Degassers
