1, equipment type: This equipment is a power-saving type product, which uses a half-bridge series inverter intermediate frequency power supply (voltage resonance). When the electric furnace is cold, hot, half-filled or filled, the half-bridge series inverter can output rated power with a constant power factor of 0.98. It has the characteristics of fast melting speed, low energy consumption and stable and reliable operation. The equipment consists of a series resonant intermediate frequency power supply and two coreless steel shell induction melting furnaces and auxiliary equipment required for the normal operation of the system.    A series resonant dual output power supply with two electric furnaces can work at the same time (commonly known as one to two), that is, the output power can be randomly distributed between the two furnace bodies, and the two furnace bodies can be simultaneously powered, one insulation , one smelt. 2, 12-pulse rectification inverter series 5T / 3500kw melting furnace main technical indicators Melting furnace working mode: 1.1 One set of furnace body is smelted and the other set is spared. Power setting is 3500kw, melting time (5T molten iron to 1550 °C) â?¤ 55 minutes / furnace 1.2 A set of furnace body melting, a furnace body insulation (refining), melting power of 3200kw insulation power â?¤Â 3 00KW / furnace. In this state, the melting time (5 T iron water to 1 5 5 0 â??) â?¤Â 60 minutes. 1.3 The two furnace bodies are simultaneously smelted and produced.
