Drying behavior of dense refractory castables. Part 2 Drying agents and design of heating schedules

Autor: Luz, A. P., Moreira, M. H., Salomao, R., Braulio, M. A. L., Pandolfelli, V. C.

Publikováno v: Ceramics International, 48 (2022) 2965-2987

Drying is the most critical process of the first heating cycle of monolithic dense refractories, as the reduced permeability of the resulting microstructure may lead to explosive spalling and mechanical damage associated with dewatering. The first pa

Report

Drying behavior of dense refractory ceramic castables. Part 1 General aspects and experimental techniques used to assess water removal

Autor: Luz, A. P., Moreira, M. H., Braulio, M. A. L., Parr, C., Pandolfelli, V. C.

Publikováno v: Ceramics International, 47 (2021) 22246-22268

Despite the continuous evolution on the performance of refractory ceramic products, monolithic materials still require special attention during their processing steps as various phase transformations may take place during the curing, drying and firin

Considerando-se as dificuldades para a utilização de MgO em concretos refratários, técnicas anti-hidratação têm sido propostas com o objetivo de minimizar os efeitos deletérios causados pela reação da magnésia com a água. Em paralelo, sur

Thermodynamic evaluation of spinel containing refractory castables corrosion by an industrial secondary metallurgy slag

Autor: Luz, A. P., Tomba Martinez, Analia Gladys, Braulio, M. A. L., Pandolfelli, V. C.

This work addresses the thermodynamic evaluation of different spinel-containing refractory castable compositions in contact with a basic steel ladle slag (CaO/SiO2 ~ 9). The main differences among the castable compositions were the amount of silica f

Concretos refratários alumina-magnésia são comumente ligados por cimentos de aluminato de cálcio. Estes materiais apresentam, em temperaturas elevadas, uma reação de caráter expansivo decorrente da espinelização in-situ (MgAl2O4). Quando lig
