>2. Electric arc furnace transformer
Used for furnace transformers used to smelt copper, copper alloys or graphite electrodes. Single or three-phase power supply can be used. The secondary voltage is generally lower than that of steel-making. This product is used alternately according to the melting cycle, full load and gap.
Working principle: This type of electric furnace transformer has a reactor, which can be directly connected to the power supply line when supplying power. The coil form is divided into cylindrical or disc type according to the capacity. The secondary coil is divided into two or four parallel connections. The product Except for those marked in the series table, there is no tap voltage regulation. When voltage regulation is required during use, the capacity transformers should be carried out through a voltage regulator. All transformers are oil conservator, and their accessories include bushings, conductive bars, thermometer seats, and oil drain valves. We wait for reference to the use of power transformers.
3. Power frequency induction furnace transformer
Overview Power frequency induction furnace directly uses power frequency power and uses the principle of electromagnetic induction to melt metal. It is widely used for melting ferrous and non-ferrous metals and various high-grade cast iron, malleable iron, ductile iron, etc.
Structural features: The load power supply of the power frequency furnace transformer is stable and generally has no overload requirements. In order to improve efficiency and have low impedance voltage and hard external characteristics, the structural design features are similar to those of power transformers of the same capacity, except for the voltage regulation method and voltage regulation range.
>4. Electroslag furnace transformer
It is a special power transformer for electroslag furnace. It is a product designed according to the process requirements of electroslag furnace method submerged arc remelting of high-quality steel, special steel and special steel products. It has The output voltage is low, the current is large, the voltage regulation range is large and fine, the external characteristics are smooth, and the operation is stable and reliable. The voltage regulation methods of electroslag furnace transformers are divided into two types: no-load or on-load tap-changer for graded voltage regulation and the use of saturated reactor for stepless smooth voltage regulation.
5. Industrial resistance furnace series
It is an electric heating equipment that uses the principle of converting electric current into heat energy through heating elements. It implements measurement, control and recording through the equipped automated instruments to heat and preserve the workpieces placed in the furnace according to process requirements to meet various usage requirements. There are many varieties and specifications of industrial resistance furnaces. Each series of models and their main technical parameters are listed in the product catalog. All products are supplied with supporting accessories and spare parts. Non-standard non-standard products for various purposes can be designed and manufactured according to the technical parameters required by users. Industrial resistance furnace.
