Fire-resistant and wear-resistant cast anchors

The surface of Metallic Anchors should usually be coated with asphalt or paraffin, or wrapped with electrical plastic tape with a thickness of 1-2mm. Since the thermal expansion coefficient of refractory castables is far from that of metal anchors, in order to prevent excessive tensile stress in the refractory castables due to large expansion during the heating process of Refractory Casting Anchors, the surface of Refractory Casting Anchors is coated with on asphalt etc. These coatings burn off during heating, leaving room for the anchor to expand freely. Anchor is made of ribbed steel or ordinary steel bar, and the diameter of the steel bar is selected according to the thickness of the castable, usually between 6-12mm. If the castable thickness is 100mm, choose 6-8mm steel bars; if the castable thickness is more than 200mm, choose 10-12mm steel bars. The height of Metallic Anchors is 70-80% of the castable thickness. The inward distance of the row of anchors is about 200mm, the distan…
