Shanghai Xinyan Industrial Equipment****.

Shanghai Xinyan Industrial Equipment Co., Ltd. is a manufacturer of intermediate frequency electric furnace and induction heating equipment invested and controlled by Shanghai Dingxin Investment (Group) Co., Ltd., which integrates R&D, production and sales.

Ningbo's Shen electric furnace, Suzhou's Zhenwu, Hangzhou's Sida, etc., the quality of these electric furnace factories is good, and the staring potato is only higher than the average small factory.

The difference between intermediate frequency furnace and high-frequency furnace] induction furnace can be divided into three types: power frequency electric furnace, intermediate frequency electric furnace and high-frequency electric furnace according to the frequency of the alternating current used. The difference between an intermediate frequency furnace and a high frequency furnace is:

1. The frequency of the alternating current used is different: the intermediate frequency furnace refers to a power supply device that converts the power frequency of 50Hz alternating current into intermediate frequency (above 300Hz to 10000Hz); High-frequency furnaces usually have a current frequency between 100 and 500 kHz under clear conditions;

2. The higher the frequency, the lower the diathermy capacity;

3. The effective hardening depth of the intermediate frequency furnace is 2 to 10 mm, and the main application range is the parts that require a deep hardening layer; The effective hardening depth of the high-frequency furnace is between 0.5 and 2 millimeters.

4. It can be used to smelt all kinds of metals from 5 kg to 60 tons in an intermediate frequency furnace; High-frequency induction heating is suitable for melting and refining precious metals from one to five kilograms.

5. The intermediate frequency furnace is large in size and mature in technology; The high-frequency furnace is small in size, runs fast, and is cheap.

Hopefully, the following information will be useful to you:

Does the simultaneous use of intermediate frequency furnace and power frequency furnace have an impact? Hello, happy to answer your <>. Pro, the simultaneous use of intermediate frequency furnace and power frequency furnace has the following effects: 1. Intermediate frequency furnace has high power density and high productivity.

That is, under the same stirring force and the same capacity, the intermediate frequency furnace can input 3 times the power of the power frequency furnace, in other words, the crucible size of the intermediate frequency furnace with the same power is only one-third of the size of the power frequency furnace crucible. In larger furnaces, due to the influence of the current and voltage of the inductor line, the input power of the intermediate frequency furnace is about two continents of the input power of the power frequency furnace. Therefore, the average power consumption of the intermediate frequency furnace is lower than that of the power frequency furnace.

2. The intermediate frequency furnace can empty the charge every time it is smelted, which is easy to replace the molten metal species, fast melting, no need to melt, and easy to use. The power frequency furnace needs to keep part of the remaining molten iron for the next furnace 4 melting, otherwise it is necessary to use frit. 3. Under the same productivity conditions, the selected intermediate frequency furnace has a small capacity, so it occupies a small area, the amount of lining material is small, and the operating cost is low 4. The operation reliability of the intermediate frequency furnace is high and the equipment utilization rate is improved.

5.Compared with the power frequency furnace, the mixing force of the intermediate frequency furnace is small, the metal scouring of the furnace lining is small, and the lining life is long. In recent years, with the development of thyristor intermediate frequency power supply technology, large-scale high-power intermediate frequency furnaces have been developed rapidly, and have been adopted by more and more users, and there is a trend of gradually replacing small and medium-sized power frequency furnaces.

The energy consumption of power frequency furnace and intermediate frequency furnace is compared and analyzed, and the necessary technical data are provided as a reference for feasibility analysis and scheme selection. In the case of the same smelting metal, the main factors affecting the power consumption of the two furnaces are: furnace capacity, daily output, frequency and power density, electric frequency and thermal efficiency of the furnace, etc. Hope mine can help you <>
