In following study the analysis of ring preform swelling and piercing process is carried out. The preform for ring rolling is produced with HRP 4000 press. The plastometric research of steel for its production was performed. The temperature field in preform preparing process was examined on the basis of research results, using FORM-2D program. A batch temperature variation during forming process was determined for currently applied technology, and for a batch which changed dimensional and a die with new construction. The new construction of a die and the changed batch allow for determining a risk of defects, which are caused by overcooling of half-products surface and a low plasticity in these conditions.
