Refractory anchor

Introduction:

Refractory anchor means a member used to join an integral refractory lining, a refractory preform, a refractory fiber mat to a furnace shell or furnace steel structure. The role of the anchor is to fix the connected lining in a position to resist static load, thermal stress, mechanical rotation or vibration. The anchor helps to prevent the collapse of the material before the formation of the ceramic during construction and heating, and also helps to make the material shrink evenly and avoid large and concentrated cracks in the liner.

Classification:

The anchor material is available in both metal and ceramic. The metal anchor is made of low carbon steel, heat resistant alloy steel, nickel chrome alloy and the like. Ceramic anchors are made from refractory raw materials that are shaped and fired. Metal anchors have many shapes, such as Y-type, V-type, T-type, and S-type. Metal anchors are refractory castables, refractory plastics and refractory spray coatings used to support and secure thinner liners. Which shape of metal anchor is used is determined by the structure of the liner. The upper and lower ends of the ceramic anchor must be flat, and the other four sides are toothed to increase the occlusal area and friction with the lining, and play the role of suspension and support.
