Abstract

Experimental study using a small scale blast furnace model as well as theoretical study based on the elastic-plastic theory were made to elucidate the characteristics of the stress field formed inside blast furnace and following results were obtained.<BR>1) The stress distributions both on the furnace wall and on the furnace bottom measured in the experiment agreed approximately with those obtained through the numerical analysis based on the elastic-plastic theory.<BR>2) The shape of deadman and the vertical distribution of the horizontal stress inside the cold model furnace observed in the experiment also agreed with those obtained through the same analysis.<BR>3) Followed by the results presented in 1) and 2), the elastic-plastic theory was confirmed to be useful to elucidate the stress field formed inside blast furnace.
