The use of a Gleeble device for measuring the hot strength of coke was evaluated. The hot strength of coke was decreased from 15.1 to 12.1 MPa when heated from 1000 to 1600°C. The strength of coke was homogenized at high temperatures. The deformation behavior of coke was brittle at 1000°C, but partially plastic at 1600°C. The decreased strength at high temperature could explain the decrease of coke size observed in quenched blast furnaces.
