Fireproof steel anchor, fireproof needle

Tamin Sanat Hafad Company supplies various types of anchors, supports and refractory bolts in various forms (rods – strips – castings, etc.) for various applications. The material of these anchors is made of refractory and stainless steel in the classes (1.4828)309, (1.4841)310, (1.4571)316, (1.4541)321, (1.4301)304, INCONEL, etc., depending on the type of application and the environment used. The characteristics of these anchors include resistance to chemical and oxidation environments, non-deformation under mechanical load, and stability at high temperatures. Depending on the type and thickness of the refractory layer used, the shape and density of the anchors per unit area also change. Refractory anchor bolts are used in all thermal departments in various industries, including cement, steel, oil, gas, petrochemical, etc.

The Tasf Industrial Group offers a complete range of metal and ceramic anchors for the installation of monolithic refractories. The correct selection of anchor quality and spacing between them is one of the essential criteria for achieving a quality refractory layer.

Metal Anchors

Metal anchors are one of the most common anchoring systems due to their lower price and easier installation. Metal anchors can be used at temperatures below 1100ºC; at higher temperatures, a combination of metal and ceramic anchors should be used. The thickness and dimensions of metal anchors depend on the type of refractory material, the thickness of the refractory layer, and the working conditions, including temperature and chemical environment.

Information on some heat-resistant alloys is given in the table below:

The correct selection of metal anchor alloy is very important. Considering the working conditions of the cement industry, Negar Tamin Engineering Group recommends the use of AISI 304 and AISI 310 alloys for anchoring. You can contact our experts to select the right anchor based on your working conditions.

Ceramic Anchors

If the refractory layer is exposed to very high working temperatures or there is a possibility of severe chemical corrosion, the use of ceramic anchors is recommended. Ceramic anchors are used in walls, ceilings and facades to hold the refractory layer.
