A problem of crystallizing steel ingot creep is considered. The ingot is undergone to load action, distributed uniformly between the supports in the cases when the ingot rests and moves over the supports. Accident and steady state processes are computed via simulation of ingot by multispan beam. The problem is solved with the use of theory of flowing with exponential creep law. The equations are deduced to define the stresses in the beam fibers and support responses.
