Provided are a method and a device for predicting a roller gap in a non-steady-state process. The method includes: obtaining a plurality of first rolling parameters; dividing, based on the plurality of first rolling parameters, a rolling deformation zone into an inlet elastic compression zone, a plastic deformation zone, and an outlet elastic recovery zone; determining a rolling force of the inlet elastic compression zone and a rolling force of the outlet elastic recovery zone through function calculations using a predetermined elastic mechanics calculation model; determining a rolling force of the plastic deformation zone through function calculations using a predetermined energy technique; determining, based on a coupling relationship between the rolling forces and a roller flattening radius, a first total rolling force of the non-steady-state process deformation zone that satisfies a predetermined convergence condition; obtaining the roller gap through function calculations using a first predetermined function model.
