Structural characteristics of ladle refining furnace equipment The overall structure of the LF-20t ladle refining furnace adopts a ladle car moving scheme. It consists of two parts: mechanical equipment and electrical equipment. The mechanical part is composed of cover, heating station bridge and furnace cover lifting mechanism, feeding hopper, electrode lifting device, short net, hydraulic station, argon gas system, cooling water system, compressed air system, etc. Vertical double-barreled shotgun receiver vacuum heat treatmentThe heating station bridge is not only the installation support for the furnace cover lifting mechanism, the electrode guide device and the feeding hopper, but also the operation platform for the electrode extension. It is welded by section steel and has a certain bearing capacity. Electrode lifting device and short net are the core components of the ladle furnace.Vacuum quenching of KMN steel structure The short network adopts an optimized triangular arrangement, so that the three-phase power is in the best working state. The electrode lifting mechanism is not only the support body of the electrode, but also the carrier for conveying large current. The electrical equipment consists of high-voltage power supply system, transformer, low-voltage power supply control system, electrode lift automatic control system, ladle car travel control system, hydraulic control system, etc.Vacuum gas Quenching of 45CrNiMo1VA Steel Spinning Mandrel
