Abstract
In this study, pyrolytic liquid obtained at 500 °C temperature, 15 °C /min. heating rate and 0,5 lt/min. nitrogen flow rate pyrolysis parameters and then 2 times extraction with 10% H2SO4 solution to decrease sulfur content was used as a binder in MgO-C refractory brick. Open porosity (%), density, cold compressive strength (CCS) and three point bending strength and elastic modulus values of the produced refractory materials were determined, and were compared with the properties of MgO-C refractory bricks produced by incorporation of phenolic resin in the refractory sector. In addition, microstructure images by scanning electron microscopy (SEM) were investigated and correlated with the mechanical properties of those refractories. Elemental analysis by X-ray fluorescence (XRF) spectroscopy and phase analysis by X-ray diffraction (XRD) were performed.
