Abstract

The use of the ribbon test method in conjunction with measurement of M.O.E. by transient vibration has proved of significant assistance in the comparison of various refractory grades for thermal shock resistance and is now proving a useful tool in the development of new products. It is hoped that, once the parameters of the test are more fully understood and standardised, it will be only necessary to measure elastic modulus before and after 10 cycles or perhaps even 5 cycles will be sufficient.
