摘要

Eleven commercially available magnesia-chrome refractories have been tested. Their basic properties have been determined along with bending strengths at 20,950 and 1400 °C, linear thermal expansion coefficients at 950 °C and 1400 °C, Young's modulus by the static method and the work of fracture at 950 °C. Young's modulus was determined within the temperature range 20-1000 °C, in the process of heating and cooling. The values of thermal shock resistance R_(st) and R_4 were calculated and correlated to thermal shock resistance (TSR). It has been demonstrated that the R_(st) criterion is a useful tool to forecast TSR, no matter whether the value of the E modulus is determined by the static or dynamic method. The values of Young's modulus obtained by various methods at 20 °C and 950 °C have been compared. It has been proven that Young's modulus dependence on temperature is a specific feature of a given material.
