  The aim of this paper is to analize the structure of BL-algebras using
commutative rings. From computational considerations, we are very interested in
the finite case. We present new ways to generate finite BL-algebras using
commutative rings and we give summarizing statistics.
  Furthermore, we investigated BL-rings, i.e., commutative rings whose the
lattice of ideals can be equiped with a structure of BL-algebra. A new
characterization for these rings and their connections to other classes of
rings are established. Also, we give examples of finite BL-rings for which
their lattice of ideals is not an MV-algebra and using these rings we construct
BL-algebras with $2^{r}+1$ elements, $r\geq 2,$ and \ all BL-chains with $k$
elements, $k\geq 4.$
