EFFECT OF STEEL FIBERS ON REFRACTORY CASTABLES

Journal 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 ...

Mullite macro-needles for reinforcement of refractory castables

Cerâmica, 2022
Ceramic macro-needles incorporation as reinforcement in commercial refractory castable was studied. Ceramic macro-needles (Ø2x20 mm) were made from kaolinite clay and gibbsite to obtain mullite as the main crystalline phase.

Analysis of the Formed Protective Layer Inhibiting Alkali Corrosion in Aluminosilicate Refractory Castables

Ceramics, 2022
This article analyzes the mechanism of the protective layer formation under the action of alkali in a refractory castable when ground quartz sand (GQS) is used as an admixture to produce refractory conventional castables (CC) and medium cement castables (

Investigation of the milling route for the development of colloidal suspensions to be used as binder in refractory castables

Open Ceramics, 2023
Refractories castables bonded with CAC (calcium aluminate cement) have a limitation when they are used at high temperature in micro-silica containing system and/or in acidic corrosive environments.

Phase Transformations and Properties Evolution of Alumina-Based Refractory Castables Containing ZnO and SiO2

Materials Research, 2022
Although most of the studies presented in the literature are focused on MgAl2O4 formation and its role on alumina-based refractories performance, ZnO has been reported as a promising spinel inducer. Aiming to investigate the influence of ZnAl2O4 (ZA) and
