内容简介

An evaluation test for plasticity of tap-hole clay was carried out focusing on the shearing rate, and a difference in the properties between specimens A and B could be shown. However, the test was executed under the condition that the shear stress loading was in the direction of the gravitational force and therefore it had to be carried out at room temperature. It is necessary to investigate the test method with the tap-hole clay at the temperature of an actual infilling operation in an iron-making blast furnace.
