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. . .
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. . .
What are monolithic refractories, classification of monolithic refractory products done on the basis of different criteria
Castables, Ramming Mass, Coating Mass, Fettling Mass, Gunning Compound, Injection Mass, Refractory Mortar, Patching Mass, Plastic Mass
‘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.
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.
An article about how the classifications of refractories and refractory materials are done into various types - Acid, Basic, Neutral, Special, Cermet, Insulating refractories and Cermet ..
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.
