  The behavior of the Landau gauge gluon and ghost propagators is studied in
pure SU(3) gauge theory at non-zero temperature on the lattice. We concentrate
on the momentum range [0.6, 2.0] GeV. For the longitudinal as well as for the
transverse component of the gluon propagator we extract the continuum limit. We
demonstrate the smallness of finite-size and Gribov-copy effects at
temperatures close to the deconfinement phase transition at T=T_c and within
the restricted range of momenta. Since the longitudinal component D_L(q) turns
out to be most sensitive with respect to the phase transition we propose some
combinations of D_L(q) signalling the transition much like "order parameters".
