Description

Whenever there is a very high temperature in the furnace lining or a severe corrosive attack is to be expected, ceramic anchoring elements are used because metallic anchoring systems reach their limits here.
The anchoring elements in the CA series, based on sillimanite / andalusite, have an alumina content of approximately 60%, which has an excellent thermal shock resistance.

The largely dimensioned head with various claws attached ensure that large retention forces can be transferred reliably onto the outer casing of this section of the system. The generously proportioned symmetrical corrugation on the shaft of the anchor ensures that the monolithic lining is firmly retained by the anchoring element.

For the attachment to the outer casing vhi offers a large selection of curved (B series) and welded (WAC series) retaining claws. They are made of wrought alloy and are therefore ductile and adapt flexibly to changes in loading conditions, which is a great advantage compared to the cast parts frequently used today, which break abruptly at critical load. The multiplicity of the different combinations of materials offers for every application the best technical and economical solution.

The BF5B-Set developed by vhi allows the anchoring system to be assembled easily, securely and with precision. It ensures precise positioning of both the claw (WAC-5) within the retaining bracket (BF5B) as welded to the casing and of the refractory anchor centrally within the actual claw. The design allows for simple cost effective installation when compared to potentially problematic alternates. - e.g. installation of wooden wedges.
The plastic elements used in the assembly become soft / melt in use allowing for necessary movement.
