Product Description

The intermediate frequency coreless induction melting furnace is an equipment used for melting and insulation of non-ferrous metals.
This equipment is a medium frequency coreless induction melting furnace (non vacuum) that uses a controllable silicon static medium frequency power supply for induction heating. It is used for melting and insulation of non-ferrous metals such as copper, aluminum, and stainless steel.Generally, it is divided into two types based on the furnace capacity: aluminum shell structure and steel shell structure. The aluminum shell structure generally adopts a tilting furnace method powered by a reducer, while the steel shell structure generally adopts a tilting furnace method powered by hydraulic pressure.

Rectifier transformer
The rectifier transformer model used in this equipment is ZSSB-20000KVA/35-1.65 * 4, including the transformer body, expansion oil pillow, and all accessories accompanying the transformer body. The cooling method is strong oil water cooling.
The transformer is equipped with protection functions such as heavy gas, light gas, and pressure relief, and is also equipped with oil temperature detection components, which can achieve high temperature alarm and over temperature trip protection. The relevant protection signals can be transmitted to the high-voltage switchgear.
The transformer capacity of this equipment is 20000KVA, which is composed of a ZSSB-20000KVA/35-1.65 * 4 transformer combination. Used to reduce the 35KV high voltage of the power grid to 1650V. The primary voltage of the transformer is 35KV, the secondary voltage is 1650V, with 12 phase output, and the secondary connection is △/Y four sets of voltage output.
Medium frequency power cabinet
The power cabinet adopts the GGD standard cabinet structure, with three segmented cabinets fixed on a groove base and connected to each other through fixing parts, forming a whole. The electrical components installed internally mainly include low-voltage vacuum circuit breakers, fast fuses, rectifiers, inverters, as well as various control transformers and drive components. There are various display instruments and operation buttons installed on the door of the electrical cabinet. The main control board, which serves as the core of the control system, is also installed on the door of the electrical cabinet.
The output of the intermediate frequency power supply can be manually switched by changing the furnace, allowing either one of the two electric furnaces to work while the other furnace body is used for tying furnace lining and maintenance. (Transformers and high-voltage cabinets to be provided by users themselves)
