PFI Tirumala steel uses Tempercore technology. Each TEMPCORE™ equipment is designed by CRM Group on the basis of precise calculations complemented with a very large experience (more than 70 mills equipped around the world, for rebar diameters up to 75 mm). Such design guarantees excellent process controllability (giving consistent product properties) and high flexibility (allowing to produce several grades with the same chemistry). Equipment manufacturing is then often carried-out locally at low cost.
