Analysis of DTA and dilatometric data used to study the behaviour of a mould flux
(2019-06-01)In the present work a casting powder containing ≈ 36 wt% SiO2, ≈ 31 wt% CaO, 13 wt% Na2O, and 10 wt% CaF2, was used as starting material. A mass of 10 g of the mould powder was placed in a graphite crucible and melted at ... -
Structural evolution of an Al2O3-MgO•Al2O3 castable in the range 1000-1600°C
(Mind Authors Inc., 2020-11-10)Thermal and structural characteristics of an alumina-spinel castable (containing 2.5 wt.% CaO) was studied. The specimens were cast (8.0 wt.% water), cured in air at ambient temperature (48 h), then dried at 100°C (24 h) ... -
Thermal analysis techniques applied to study wear mechanisms of black refractories used in the steel continuous casting process
(Springer, 2019-06-01)In this paper, the results are correlated with information obtained through conventional techniques such as optical microscopy (OM) and scanning electron microscopy (SEM) including EDS analysis and EBSD, that are used to ...
