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 ...

Corrosion mechanisms of Al2O3-SiC-C refractory castables by iron and slag based on post-mortem analysis of industrial samples

Open Ceramics, 2023
The Al2O3-SiC-C or ASC castables are used in the main runners of blast furnaces. Most of the papers published to date focus on laboratory corrosion tests because access to the post-mortem samples of ASC castables is difficult.

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 (

Reasons for crack propagation and strength loss in refractory castables based on changes in their chemical compositions and micromorphologies with heating: special focus on the large blocks

Journal of Asian Ceramic Societies, 2019
Among the most significant problems in industrial refractory manufacture, especially of monolithic refractories, are the formation of cracks and loss of strength in green bodies or during heating of the refractory castables.

Permeabilidade de concretos refratários multifuncionais Permeability of multifunctional refractory castables

Cerâmica, 2001
Concretos multifuncionais oferecem como principal vantagem a possibilidade de aplicação do material refratário através de diversas técnicas de instalação (p.e. socagem, vibração, projeção, auto-escoamento) variando-se apenas o teor de água.

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.

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.
