Unless the ring by design will have restriction for any outward expansion. The hole will get larger / bigger as you heat this up. The more you heat an object the more it expands, thus the larger the hole gets. The only case is when outward expansion is restricted, the expansion will be inward as it is the only direction the ring can expand to.
