What is the difference between a power frequency induction furnace and a medium frequency induction furnace?

Chekutanga, simba frequency induction furnace

Iyo magetsi frequency induction furnace ndeye induction vira inoshandisa yazvino yemaindasitiri frequency (50 kana 60 Hz) sesimba sosi. Iyo magetsi frequency induction furnace yakagadziridzwa kuita simbi yekunyungudutsa ine huwandu hwakawanda hwekushandisa. Inonyanya kushandiswa sechoto chinonyunguduka chekunyungudutsa grey cast iron, inogoneka yakakandwa simbi, ductile iron uye alloy cast iron. Mukuwedzera, inoshandiswawo sechoto chekubata. Sekare, iyo magetsi frequency induction furnace yakatsiva iyo cupola sechinhu chikuru chekugadzira kugadzirwa. Kuenzaniswa nekapu, iyo yemagetsi frequency induction vira ine kuumbwa kwesimbi yakanyungudutswa uye tembiricha, uye gasi mukukanda iri nyore kudzora. Pane zvakawanda zvakanakira zvakadai seyakaderera inclusions, hapana kusvibiswa kune zvakatipoteredza, kuchengetedza simba uye kuvandudzwa kwemamiriro ekushanda. Naizvozvo, mumakore achangopfuura, iyo magetsi frequency induction furnace yakagadziridzwa nekukurumidza.

Iyo simba frequency induction furnace yakazara seti yemidziyo inosanganisira zvikamu zvina.

1. Chikamu chevira

Icho chikamu chemagetsi emagetsi induction vira chesimbi yakanyungudutswa inoumbwa nechoto chekunyungudutsa (mayuniti maviri, imwe yekunyungudutsa uye imwe yekumira), chivharo chechoto, furemu yevira, silinda inonyungudika, uye chivharo chinofamba chinovhura uye. kuvhara mudziyo.

2. Zvikamu zvemagetsi

Chikamu chemagetsi chine simba rekushandura, main contactor, balanced reactor, balancing capacitor, compensation capacitor, uye magetsi console.

3. Cooling system

Kutonhodza mvura masisitimu anosanganisira capacitor kutonhora, inductor kutonhora, uye yakapfava tambo kutonhora. Iyo yekutonhodza mvura system inoumbwa nepombi yemvura, dziva rinotenderera kana shongwe yekutonhodza, uye vharafu yepombi.

4. Hydraulic maitiro

MaHydraulic masisitimu anosanganisira matangi emafuta, pombi dzemafuta, mota dzepombi dzemafuta, hydraulic system piping uye mavharuvhu, uye hydraulic consoles.

Second, the intermediate frequency induction furnace

Induction furnaces ine yepakati frequency induction furnaces ine frequency yesimba muhuwandu hwe150 kusvika 10,000 Hz inonzi yepakati frequency induction furnaces, uye mafrequency avo makuru ari muhuwandu hwe150 kusvika 2500 Hz. Domestic diki frequency induction choto chemagetsi emagetsi frequency ndeye 150, 1000 uye 2500 Hz.

The medium frequency induction furnace is a special equipment suitable for smelting high quality steel and alloy. Compared with the power frequency induction furnace, it has the following advantages:

1) Fast melting speed and high production efficiency. The power density of the medium frequency induction furnace is large, and the power configuration per ton of molten steel is about 20-30% larger than that of the power frequency induction furnace. Therefore, under the same conditions, the medium frequency induction furnace has a high melting speed and high production efficiency.

2) Kuchinja uye kushandiswa kushandiswa. Muchoto chepakati frequency induction, simbi yakanyungudutswa yevira yega yega inogona kucheneswa zvachose, uye zviri nyore kutsiva simbi. Nekudaro, iyo simbi yakanyungudutswa yemagetsi frequency induction furnace haibvumidzwe kucheneswa, uye chikamu chesimbi yakanyungudutswa chinofanira kuchengeterwa kutanga choto. Nokudaro, hazvibatsiri kutsiva simbi, inoshanda chete. Kunyungudutsa rudzi rumwe chete rwesimbi.

3) Electromagnetic inosimudzira mhedzisiro iri nani. Sezvo simba remagetsi resimbi yakanyungudutswa yakaenzana neskweya midzi yemagetsi emagetsi frequency, simba rinokurudzira repakati pemagetsi emagetsi idiki pane iro rekutengesa frequency magetsi magetsi. Nekubvisa kusvibiswa uye yunifomu yemakemikari kuumbwa musimbi, yunifomu tembiricha, iyo inosimudzira mhedzisiro yepakati frequency magetsi ekupa zviri nani. Kuwedzeredza kuwedzeredza kwesimba remagetsi frequency magetsi kunowedzera simba rekunyungudutsa resimbi yakanyungudutswa kune lining, izvo zvisingangodzikisire kunatsa asi zvakare zvinoderedza hupenyu hweiyo crucible.

4) Zviri nyore kutanga uye kushanda. Sezvo ganda mhedzisiro yepakati frequency ikozvino yakakura zvakanyanya kupfuura simba frequency ikozvino, yepakati frequency induction furnace haina zvakakosha zvekuchaja kana uchitanga, uye inogona kupisa nekukurumidza mushure mekuchaja; nepo iyo magetsi frequency induction choto inoda yakanyatsogadzirwa yakavhurika zvinhu block. (Inenge simbi yakakandwa kana simbi yakakandwa, iyo inenge saizi yecrucible, iyo inenge hafu yehurefu hwe crucible) inogona kutanga kupisa uye kupisa kwekushisa kunononoka zvikuru. Naizvozvo, yepakati frequency induction furnace inowanzoshandiswa pasi pemamiriro ekushanda nguva nenguva. Imwe mukana weiyo nyore kutanga-up ndeyekuti inochengetedza simba panguva yekutenderera mashandiro.

Due to the above advantages, the medium frequency induction furnace has not only been widely used in the production of steel and alloys in recent years, but also in the production of cast iron, especially in the casting workshop of the cycle operation.

Auxiliary equipment for medium frequency induction furnace

Iyo yakazara seti yepakati frequency induction furnace inosanganisira: magetsi uye magetsi ekudzora chikamu, choto chikamu, kutapurirana uye kutonhora kwemvura system.
