>> Sampling of Refractory Specimens for Inspection

Drawing refractory samples commonly known as Sampling of Refractories is an important function done before inspection. The inspection procedure starts by selecting, generally a minimum number of units, called a ‘Sample’, from the refractory lot ... Methods of Samplling Inspection ..

3 Golden Rules to achieve better Refractory Life and Performance

3 simple processes which can significantly improve the performance of refractories and refractory life . . 

Importance of Tundish Design and Flow Modifier Refractories in Steel Making

One of the major functions of steel making tundish is to enhance inclusion floatability and thereby, produce clean steel. For the removal of inclusion through floatation, wall adhesion and agglomeration the flow patterns inside the tundish play an important role, which in turn is a function of tundish design. . . 

Type of Monolithic Refractories - Monolithic Refractory Products

What are monolithic refractories, classification of monolithic refractory products done on the basis of different criteria

Nomenclatures and Terminologies of Monolithic Refractory Products based on their setting or installation methods

Castables, Ramming Mass, Coating Mass, Fettling Mass, Gunning Compound, Injection Mass, Refractory Mortar, Patching Mass, Plastic Mass 

Calcination of Refractory Raw Materials in different Kilns

‘Calcination’ is the heat treatment below the melting point to which a material is subjected, preparatory to further processing or use, for the purpose of eliminating chemically combined volatile constituents and to ensure stability through high temperature volume changes - purpose, process of calcining refractory raw materials in different kilns - its benefits.

Pyrometric Cone Equivalent (PCE) Test in ORTON or SEGAR to Determine Refractoriness of a Refractory Material

Heat resistance capacity (refractoriness) of a refractory material is determined by Pyrometric Cone Equivalent (PCE) test by comparing ceramic specimen of known softening behaviour in ORTON or SEGAR Cone with the Cone of the refractory material.

​​Standard Methods for Testing of Refractories and Refractory Materials

The necessity of refractory standards and also setting standard methods for testing of refractories and refractory materials such as ISO, ASTM, DIN, BS, IS, GOST as followed in different countries by refractory producers and end-users depending on the specific requirements or suitability.  

Refractory Industry in India struggling to survive 

The refractory industry in India, reached a comfortable position after having achieved a growth of more than 25 per cent in exports just a few years ago is now struggling hard for survival. Refractories are the fundamental pre-requisites (raw materials) for any high temperature operation. . .
