Anchors

Refractory anchor systems are manufactured for all types of monolithic and brick refractory linings confirming that the exact grade of material, dimensions, spacing patterns and welding methods are selected for an anchorage system which is very necessary for retaining the refractory material and ensures the lining performance.

Types of Anchors

SS Anchor Ceramic Anchor
SSAnchor

All refractory anchor hardware is wire formed,die stamped, roll threaded and welded into a variety of anchoring products for castable monolithic, abrasion resistant and ceramic fibre refractory linings.

  • AISI 304: As our recommendation, AISI 304 is can be used in the area withtemperature less than 7000C.
  • AISI 310: AISI 310, due to the increase in Nickel and Chromium ascompared to AISI 304, can be used in the temperature up to 1,1000C, however, due to highnickel content, AISI 310 is weak against sulphur, which try to combine with the nickel of the alloy and weaken the alloy.
  • AISI 253MA: AISI 253MA (MA stands for MicroAlloy), which is a better solution for refractory castable lining of today's operation of cementplant.253MA is an austenitic stainless steel designed primarily for use at maximum temperatures upto 1,1500C (slightly than that of AISI 310).
 CeramicAnchor

A premium super duty, Ceramic anchor finds application in Cement, Boilers and lime kilns, reheat furnaces, non-ferrous furnaces, and a variety of other applications.

  • C-Series: C-Series Ceramic Anchors are designed for VC/VCX -Series clips and the R-604/VR and VT/VTP -Series Roof Hanger type Attachments. Various grades are available along with several mounting assemblies.
  • T-Series: T-Series Ceramic Anchors are designed for the ER-Bolt washer assembly. These are primarily used in thick wall constructions or for special applications.
  • Ceramic Anchor qualities:
  • PR-45 - A premium super duty, fireclay anchor designed for severe super duty refractory applications
  • PR-70 - A mullite/andalusite based high alumina anchor with excellent hot properties, alkali resistance and thermal shock resistance.
  • PR-85 - A premium 85% alumina brick anchor exhibiting excellent strength and good alkali and slag resistance.
  • PR-90 - A high purity, 90% alumina brick anchor designed for severe service conditions.
ShimPlates

Shim Plates

The main functions on the Shim Plate are to fuse the brick and the other to conduct the heat to the shell to promote the formation and solidification of the eutectic elements of the Clinker and there by providing the initial requirements for building up the coating.
 
 

Shapes of Anchors

FlatAnchor

Flat Anchors

Flat Anchors were the most common shape in the past, because they are very easy to fabricate, so any steel workshop can make them. Flat Anchors are made by cutting stainless steel sheet into strips, and then the trips are bent into Y-shape.
Wire Anchor

Wire Anchor

Wire Anchors are more complicated to fabricate. Due to round cross-section, Wire Anchors offer round cross-section to support the weight of castable. Even after corrosion from long usage, the remaining part of WireAnchors is still bigger than that of the Flat Anchors.
Y-shape Anchor

Y-shape Anchor

The idea is to join 2 pieces of wires by welding to form Y-Shape, hoping that it will hold the castable. However, due to low melting point ofthe welding material (only around 5000C) that is used to join the 2 wires together, when inoperation the welding joint is mostly broken apart, resulting in separation of the two wires.
