摘要： PURPOSE:To reduce a concentration of a thermal stress by a method wherein a first slit is arranged at a first connecting part where a furnace wall and a sub-side wall crossed to each other in a three-dimensional manner and further a second slit is arranged at a connecting part where the sub-side wall and a rear heat transmitting wall are crossed to each other in a three-dimensional manner. CONSTITUTION:A first connecting part 8a is arranged at a corner part where a side wall 11 of a furnace wall 1, a bottom wall 4 of a sub-side wall 2 and a side wall 5 are connected to each other in a three-dimensional manner. In turn, a second connecting part 8b is arranged at a corner part where the bottom wall 4 of the sub-side wall 2, the side wall 5 and a front wall 6 of a rear part heat transmitting wall 3 are connected to each other in a three-dimensional manner. A slit 14-1 having a predetermined length is formed in a direction where the sub-side wall bottom wall 4 extends from the connecting part 8a while this connecting part 8a being applied as a starting point. A slit 26-1 having a predetermined length is formed in an upward direction where a side wall 5 of the sub-side wall 2 extends from the connecting part 8b while the connecting part 8b being applied as a base point.

摘要： PURPOSE:To clearly evaluate the characteristics of a machinery constitutional material by expressing the relation between the degree of the superposition of the magnitutes of various influence factors exerted on the phenomenon such as the environmental damage of the machinery constituting material and the life of the material as an index. CONSTITUTION:Noticing an arbitrary influence factor with respect to various influence factors exerted on the phenomenon of a machinery constituting material, the degree of other influence factors is made constant and the first relation between the magnitude of the noticed influence factor and the degree of the phenomenon is calculated to determine the degrees of the standards of various influence factors to calculate the second function of the degree of the phenomenon when various influence factors take a standard value. The ratio of the first and second functions is operated to be set to the function of the fragmenting index of the noticed influence factor and the product of each influence factor and the function of the fragmenting index is multiplied by a correction factor to be set to an index showing possibility to generate the phenomenon.
