Refractory materials must be anchored in place to support the lining ie roof/nose arch and to fix the refractory lining to the furnace casing. IMS provide a vast range of fixings for this purpose. Anchors are available in metalic and ceramic format.

Floating Wall Anchors – Wiggly ‘V’ type. Used in walls: Cleat is welded to casing, anchor sits in cleat.

Rotary Kiln Anchors – A ‘V’ tack welded to a square cleat, which is welded to the casing.

Hex-mesh Anchors – For thin linings, petrochemical applications.
pic13
Crook Anchors –  For tight/different spaces. Used for veneered/patch repairs, with a wedge anchor.
pic14
Y-Anchors – 2 part anchor for multi-component linings. The stud part of the anchor will retain back-up layers of board, whilst the V can anchor castable

V-Anchors – For single component lining or back up layer.

Features: Ceramic Anchors

  • Suitable for high temperature applications
  • Used when anchorage is required through to the hot face lining
  • Greater cross sectional area/key

Ceramic Anchors – Temperature Rating

Alumina Content

40-50%                                           1400°C

60-70%                                            1500°C

Roof hangers available in different lengths. Can be custom made to fit different beam sizes & profiles

Features – Metalic Anchors:

  • Generally economical and practical to use
  • Temperature limitations can restrict application

Metalic Anchors – Fixing Methods:

  • Stick welding – usual method
  • Stud welding – when large quantities are involved to reduce installation time
  • Bolt on via Drill casing – for ease of future replacement or demolition
  • Cleat Welded to casing – to accept floating anchor
  • Wedge Anchor – for veneering repairs where the anchor is wedged directly into the refractory
