The authors test for the deformation and strength characteristics of dinas samples taken from liners of blast furnaces before and after service under uniaxial tension and compression at temperatures ranging to 1600 C in the interest of increasing furnace temperature and optimizing time and efficiency factors. They establish that the ultimate strength decreases with increasing temperature and that when subjected to cyclic heating under alternating oxidizing and reducing atmospheres the dinas bricks exhibit embrittlement and softening. The temperature at which the strength properties decrease abruptly is found to be 1600 C.
