摘要

Short-term creep data at 1300℃ for Dinas samples cut from the brick lining of the heating walls in coke furnaces after prolonged operation (up to 31 years) indicates that, on the basis of generalized creep diagrams, the primary creep curves ε~cr(t) may be described by a power law: ε~cr = ct~a. The generalized creep diagrams are also described by a power law ε~cr=(1/αηA)~a(σ~2t)~α with the same exponent a. Values of a-the slope of the generalized creep diagram-are measured at different times: it increases from 0.314 before operation to 0.334 after prolonged service. The increase in a indicates restructuring of the material, accompanied by decrease in the remaining life of the refractory.
