Anchors are an indispensable and important part of the ceramic fiber furnace lining system. They are of various types and have different performances. When selecting, factors such as the structural form, operating temperature and operating environment of the industrial kiln should be comprehensively considered to ensure the safety and stability of the anchoring system.
(1) Overview of anchors
Anchors are commonly used connecting and fixing components in the installation and construction of ceramic fiber modules. Their main function is to firmly fix the module lining or prefabricated components in the specified position, effectively withstand external forces such as static loads, thermal stress and mechanical vibration, and prevent the structure of the refractory lining from loosening or collapsing. At the same time, the reasonable arrangement of anchors can also help to evenly release the stress of thermal expansion and contraction, reducing the risk of crack concentration.
When selecting anchors, the basic principle of "easy installation, stable structure and reliable performance" should be followed.
(2) Types of heat-resistant steel anchors
According to different module structures and installation methods, common anchor types include:
Module prefabricated anchors:
Angle iron anchors, diamond anchors, butterfly anchors, hanging anchors, corner anchors, etc. Anchors for folding blocks:
H-shaped anchors, quick clips, rotating clips, ribs, screws and nuts, U-shaped nails, V-shaped nails, etc.
(3) Classification by temperature resistance
According to the high temperature resistance of the material, anchors are mainly divided into the following categories:
201 stainless steel anchors: Suitable for environments below 600℃;
304 stainless steel anchors: Recommended operating temperature is 600℃ to 1100℃;
310 stainless steel anchors: Can withstand working temperatures up to 1200℃;
316 stainless steel anchors: With excellent heat and corrosion resistance, suitable for high temperature conditions up to 1400℃.
