Anchoring parts refer to the components used to connect the overall refractory lining, refractory prefabricated parts, refractory fiber felt and furnace shell or furnace steel structure. The function of the anchor is to fix the connected lining in a certain position to resist static load, thermal stress, mechanical rotation or vibration. The anchors help prevent the material from collapsing before the ceramic bond forms during construction and heating. It also helps to uniformize the shrinkage of the material and avoid the formation of large, concentrated cracks in the lining.
