Numerical Simulation of Thermal Shock Tests of Carbon-Containing Refractories

Abstract:

To appraise the thermal shock resistance of carbon-containing refractories correctly, its thermal stress changes in thermal shock tests were analyzed by finite element method, and the mathematical model appraising its thermal shock fracture was built. The results show when the sample of carbon-containing refractory suffers thermal shock, the main damaged areas lie its centre during sharp heating process, but the sides during quenching process. The later is the main reason causing its damage. When appraising the thermal shock resistance of carbon-containing refractory by dip spalling method, the result matches fracture index.
