The Behaviour of Monolithic Refractory and its Importance for the Design of Refractory Structures

Abstract Understanding the behaviour of monolithic refractory concrete is critically important for engineers when designing refractory linings for high temperature environments. As cement plants, power plants and other industries push for longer runtimes to reduce maintenance costs, the performance of refractory linings is critical in maintaining plant reliability. A successful refractory lining requires consistent quality […]

Designing and Failure of Monolithic Refractory Structures – Part 2

Introduction Part 1 of this paper has highlighted the errors in refractory design methodology and a general methodology for the design of monolithic refractory structures is presented. In particular it has been shown that traditional concepts or guidelines are erroneous which are not based on engineering science can leave open the risk for catastrophic failure. […]

Refractory Concrete Reinforced With Stainless Steel Fiber

Abstract Concrete materials like refractories are strong in compression and very weak in tension. This generally means that their fracture toughness is low. Stainless steel fibres are commonly used in an endeavour to improve refractory fracture toughness. Considerable emphasis has been placed on measuring fracture energies of refractory materials to reduce cracking and improve in-service life. Fracture energies […]

Designing and Failure of Monolithic Refractory Structures – Part 1

Introduction The design of static refractory structures has traditionally been based on empirical or trial and error methods and has evolved over the years. Design methodology has been based on heat transfer analysis for material selection and the most common selection criteria are the published scaling temperatures of the anchor steel in an oxidization environment […]

Selecting Steel Anchors for Monolithic Refractory Linings

Abstract The reliability of stainless steel refractory anchors in refractory lined process vessels is becoming more critical as companies chase greater efficiencies and safety. Therefore understanding the failure mechanism of stainless steel refractory anchors is the key to improved production efficiencies and better safety. The most common refractory anchor failure is at the interface between […]
