VID, acronym of Virtual Inertia Drive, is the new hydraulic drive that Danieli proposes in forging open die applications.
His aim is to keep the same size and performances of a conventional forging machine, but reducing the total electrical power installed, the n° of motor-pumps unit and the energy consumption.
System is made by the following components :
1. Hydraulic...
Typical heat treatment of structural steel forgings consists of quenching and tempering (QT). However, in case of heavy forgings (thickness above 120 mm), made of steels with carbon content less than 0.25% and low hardenability, the required strength can be achieved, but low temperature impact toughness could be not fully adequate. In this work, an intermediate intercritical quenching (IIQ)...
Radial axial (RAW) ring rolling is a well-established incremental forging process producing seamless rings and shells, both with rectangular as well as profiled cross sections, with high demands in terms of mechanical properties and microstructure, standing out for its productivity. Rolled rings and shells are applied in many industrial fields, e.g. wind power, nuclear industry, general...
Hot Radial Axial Ring Rolling is a crucial process in seamless ring production for various industrial sectors, ranging from oil & gas to aerospace. To configure and optimize this complex process, modern rolling mills rely on computerized controls, where operators must input process parameters derived from multiple sources-including tables, formulas, experience, and time-consuming FEM...
Nowadays, titanium (Ti) alloys play a pivotal role in aerospace and energy production sectors due to their specific mechanical properties. To date, the design of forged components in Ti alloys has been based on the experience of operators and engineers, and on the use of industrial tests to optimise production processes. However, the high production costs of these components and their possible...
