When the crate is moving at a constant speed, it means that the forces acting on the crate are in a state of equilibrium. This means that the force of friction acting against the crate, which is equal in magnitude and opposite in direction to the force you are applying to the crate, is also constant. Therefore, the force of friction is the same as your pushing force.
