EFFECT OF STEEL FIBERS ON REFRACTORY CASTABLES

open access: yesJournal of Engineering, 2002
Reinforcement of refractory castables with steel fibers improves their strength for cracking and spalling and expands the service life. The results show that raising the temperature from 700°C to 900°C causes an increase in porosityand decrease in ...

Thermomechanical Characterization of Monolithic Refractory Castables [PDF]

open access: yesAdvances in Science and Technology, 2010
This paper deals with the characterization of the thermomechanical behavior of monolithic refractory castables in a wide temperature range, up to 1200°C. Different test types are considered: tensile tests, compression tests, bending tests and tests on more complex shapes and geometries.

Investigation of fracture behavior of typical refractory materials up to service temperatures

open access: yesInternational Journal of Ceramic Engineering & Science, 2022
In service, refractory linings experience thermal stresses typically exceeding their mechanical strength. However, this does not lead to the catastrophic failure of modern well‐designed refractory linings. They rather undergo a more or less stepwise wear

Corrosion of bauxite‐based refractory castables and matrix components in hydrogen containing atmosphere

open access: yesInternational Journal of Ceramic Engineering & Science, 2022
For the transformation to a CO2 neutral industry, fuel of traditionally fossil‐fired furnaces is substituted by the subsequently addition of hydrogen.

Deflocculants for refractory castables (review)

open access: yesScientific research on refractories and technical ceramics, 2020
Review and analysis of foreign studies aimed at researching the influence of various deflocculants on properties of refractоry castables have been executed. Technological efficiency of deflocculants application had been shown:– ADS/W brands comparison to polyacrylate and sodium threepolyphosphate in alumina-cement-based mixture in terms mass`s humidity

Corrosion Mechanism of A Density-Reduced Steel Ladle Lining Containing Porous Spinel-Calcium Aluminate Aggregates

open access: yesCeramics, 2020
Refractory monolithics for steel ladle linings are typically products with low porosities and high bulk densities. They achieve high temperature, penetration, and corrosion resistance.

Influence of deflocculants on the cement hydrate phase formation and technological properties of CAC-bonded castables during the first heating process

open access: yesOpen Ceramics, 2023
The mechanism of growth and decomposition of calcium aluminate cement hydrate phases (CAH phases), which determine the drying behaviour of calcium aluminate bonded castables are not well understood.

Evaluation of the combined addition of aluminum lactate and calcium carbonate to alumina-based castables [PDF]

open access: yesCerâmica, 2021
Calcium aluminate cement (CAC) can induce the development of high green mechanical strength to refractory castables in a short period of time (24 h). However, the production of this hydraulic binder is energy-intensive and releases a large content of ...

Crack-free caustic magnesia-bonded refractory castables [PDF]

open access: yesCeramics International, 2021
A growing interest in designing high-alumina MgO-bonded refractory castables has been identified in recent years due to the magnesia ability to react: (i) with water at the initial processing stages of these materials (inducing the precipitation of brucite phase) or (ii) with alumina, giving rise to in situ MgAl2O4 generation at high temperatures ...
