Anchors are generally divided into two types: metal and non-metal. One end of the anchor is welded to the kiln iron shell and the supporting steel frame, and is embedded in the refractory castable to support and connect. The setting of the anchors of the refractory castable should be in accordance with the design regulations. Usually, metal anchors are used at low temperature parts, and ceramic anchor bricks are used at high temperature parts.
The metal anchors adopt different forms according to different parts of the furnace structure. Generally, the front end of the metal anchors is buried to 2/3 of the thickness of the furnace wall; the anchoring bricks are generally exposed on the heating surface.
The installation spacing of metal anchors depends on the thickness and height of the furnace wall. Generally, the horizontal spacing is about 550~600mm, and the vertical spacing is about 450~500mm. When using anchor bricks, the spacing of the side wall parts is mostly 300~500mm, and the furnace top part is about 200~300mm.
