Anchor-loc® 3 Ceramic Fiber Modules

Refractory Ceramic Fiber (RCF). Temperature Grade:  1260°C  (2300°F), 1425°C (2600°F).

The Anchor-Loc® 3 Insulating Fiber Module is designed to meet a wide range of application requirements in many types of heat processing equipment.

Unifrax specifications require inorganic spun fiber blankets for construction of the Anchor-Loc 3 module. The spinning process produces a long, tough fiber that contributes to the strength and stability of the needled blanket. Anchor-Loc 3 modules are manufactured from either ceramic fiber or soluble fiber chemistries to meet customers’ specifications or regional product requirements.

The two ceramic fiber blanket chemistries used for Anchor-Loc 3 construction are Durablanket® S and Durablanket Z  with temperature grades of 1260°C  (2300°F) and 1425°C (2600°F)  respectively. Anchor-Loc 3 modules are also constructed from biosoluble insulating blankets.

Anchor-Loc 3 modules are formed by folding a continuous strip of insulating blanket in a serpentine pattern. Next, the folded blanket is compressed and banded to assure close dimensional control of the finished block. A stainless steel base bar is inserted into the back surface of the block. For ease of attachment in the field, an access tube extends from the center of the module surface to the alloy base bar. This access tube is removed after installation is complete. Two stainless steel tubes are inserted through each fold of blanket to attach the insulating fiber to the module base bar.

EACH MODULE IS SUPPLIED WITH A D-2 THREADED FASTENER ASSEMBLY TO ATTACH THE MODULE TO THE FURNACE CASING. THE D-2 WELD STUD AND HEX NUT ASSEMBLY PROVIDES ALL OF THE FEATURES AND BENEFITS OF A PRE-WELDED FASTENER:

  • Compatibility with mastic coatings, backup insulation and foil vapor barriers.
  • Built-in compression due to the pre-engineered weld stud layout.
  • Access to the welded fastener for inspection or testing prior to module installation.

In addition, the D-2 weld stud features a pilot thread that attaches to an alignment tool for ease of module placement and fast installation. During installation the alignment tool and D-2 socket prevent cross-threading of the hex nut and stud even if studs are welded at a slight angle to the casing.
