Deformation of coke-furnace heating walls under the action of nonsteady forces and temperatures

The hierarchical model of Dinas ceramic based on defining relations with a minimum of implicit parameters permits assessment of the viability of Dinas structures and prediction of the creep and long-term strength of the heating walls in coke furnaces. However, prediction of the cyclic creep is also required, on account of the cyclic variation in the heating-wall temperature and the load (the coking pressure). The prediction of the creep curves at hazardous points of the heating walls is considered, in the light of the simultaneous variation in stress and temperature during coke-battery operation.
