Investigation of thermal shock behaviour of MgO-C refractories by incorporation of pyrolytic liquid as a binder

Tire waste is a serious problem for environment, health, and safety due to growing in volumes of its production. Recycling and recovery of waste tire as a useful product has a real importance. In this study, pyrolytic liquid obtained by waste tire pyrolysis was incorporated into MgO-C refractory as a binder to investigate the effects of its utilization on the thermal shock resistance of MgO-C refractories. The physical properties such as open porosities, densities, and mechanical properties such as Cold Crushing Strength (CCS) and 3-Bending Strength were investigated before and after thermal shock test at 1000 degrees C. The microstructure and fracture surfaces were characterized by using the Scanning Electron Microscopy (SEM). Elemental analysis of those refractories were examined by the Energy Dispersive X-Ray (EDX) analysis. Experimental studies showed that refractories produced by the use of pyrolytic liquid as a binder could have less reduction in their strength values after the thermal shock test.
