No-Cement High-Alumina Self-Flow Castable
The physicomechanical properties of heat-treated high-alumina
castables were studied Swapan Kr. Das, Ritwik Sarkar, Pradip Kr. Mandal and Somnath

Mullite-Based
Refractories for Molten-Metal Applications
A mullite-based refractory tube was fabricated using three methods:
extrusion, isostatic pressing and ramming. The ramming method was
found to be the most cost-effective. Sadanand Achari and L.N. Satapathy
Use of Steel Fibers in the Refractories Industry
Steel-fiber-reinforced castables are widely used under severe
conditions because of their high mechanical strength and thermal
shock resistance. Hamed Samadi

Effect
of Polymeric Fibers on Refractory Castable Permeability
Polypropylene fibers were added to a castable to determine
their effects on permeability and porosity. R. Salomão, F.A. Cardoso, M.D.M. Innocentini, V.C.

Aluminum-Containing Refractory Castables: Part
1, Evaluation of Hydrogen-Gas Generation
A comprehensive study of the parameters that affect
the generation of hydrogen-gas in aluminum-containing
castables. M.D.M. Innocentini, L.A. Nascimento, A.E M. Paiva,
V.C. Pandolfelli, B.A. Menegazzo and L.R.M. Bittencourt
Effect
of Synthetic Aggregate on Alumina Castables Swapan
Kumar Das, Pradip Kumar Mandal and Ritwik Sarkar
Three synthetic refractory aggregates–based on fly
ash, kyanite and sillimanite sand–were used in high-alumina
no-cement self-flow castables. Hot strength (MOR) of the
castables improved remarkably and self flow, densification
and cold crushing strength were not significantly affected. View Article
PSD,
Polymeric Fibers and the Permeability of Refractory Castables R.
Salomão, C.S. Isaac, F.A. Cardoso, M.D.M. Innocentini and
V.C. Pandolfelli
The permeability of castables designed using various
PSDs was affected in distinct ways by the addition of polymeric
fibers having the same diameter but variable lengths. View Article
High-Carbon-Content
Refractory Castables I.R.
Oliveira, R. Salomão, V.C. Pandolfelli and A.R. Studart
The use of appropriate surfactants is an effective approach
to obtain high-carbon-content castables with minimal water
consumption. View Article
The
Refractories Industry–Worldwide and China Liu
Jiehua and Zhou Ningsheng
The present situation of the worldwide refractories
industry, in terms of production volume, steel industry consumption,
marketing, trading and structural change, is reviewed. View Article
Reaction
Sintering of Alumina-Rich Magnesium Aluminate Spinel Arup
Ghosh and Ritwik Sarkar
Refractories Div., Central Glass & Ceramic Research Institute, Kolkata, India.
Alumina-rich
magnesium aluminate spinels were reaction-sintered by changing
the reactivity of alumina through calcination. A calcination
temperature of 1200°C was found to be optimum. View Article
