Kala soocida aasaasiga ah ee foornada induction

Induction furnaces can be divided into high frequency furnaces, intermediate frequency furnaces and industrial frequency furnaces according to the power frequency; according to the process purpose, they can be divided into melting furnaces, heating furnaces, heat treatment equipment and welding equipment; according to their structure, transmission mode, etc. sort. Commonly used induction furnaces are habitually grouped into hearted induction melting furnaces, induction melting furnaces, vacuum induction melting furnaces, induction hardening equipment and induction head thermal equipment, etc. The name of the smelting furnace is relative to the induction smelting furnace. The molten metal is contained in a crucible, so it is also called a crucible furnace. This type of furnace is mainly used for smelting and heat preservation of special steel, cast iron, non-ferrous metals and their alloys. The coreless furnace has many advantages such as high melting temperature, less impurity pollution, uniform alloy composition, and good working conditions. Compared with the cored furnace, the coreless furnace is easier to start and change the metal varieties, and it is more flexible to use, but its electric and thermal efficiency is far lower than that of the cored furnace. Due to the low surface temperature of the coreless furnace, it is not conducive to smelting that requires high-temperature slagging processes.

Foornada dhalaalaysa waxay u qaybsantaa soo noqnoqoshada sare, soo noqnoqoshada dhexdhexaadka ah iyo inta jeer ee awoodda.

(1) Foornada dhalaalaysa ee soo noqnoqota

Awoodda foornada-soo-celinta-sare waxay guud ahaan ka hooseysaa 50 kg, taas oo ku habboon in la dhalaaliyo birta gaarka ah iyo alaabada gaarka ah ee shaybaarada iyo wax soo saarka yaryar.

(2) Foornada dhalaalaysa inta jeer ee dhexdhexaadka ah

Awoodda iyo awoodda foornada dhalaalidda soo noqnoqda ee dhexdhexaadka ah ayaa ka weyn tan foornada soo noqnoqda ee sarreeya. Inta badan waxaa loo isticmaalaa dhalaalinta biraha gaarka ah, birta birta ah iyo daawaha naxaasta. Sababtoo ah foornada noocan oo kale ah waxay u baahan tahay qalab beddelaad joogto ah oo qaali ah, waxa loo beddelay foorno aan badnayn oo inta jeer ee tamarta ah marmarka qaarkood awoodda. Si kastaba ha noqotee, marka la barbardhigo foornada soo noqnoqda ee warshadaha, foornada soo noqnoqda ee dhexdhexaadka ah waxay sidoo kale leedahay sifooyin gaar ah. Tusaale ahaan, foornada awoodda isku midka ah, awoodda gelinta ee foornada soo noqnoqda ee dhexdhexaadka ah ayaa ka weyn tan foornada soo noqnoqda ee warshadaha, sidaas darteed xawaaraha dhalaalku waa dhakhso. Foornada inta jeer ee dhexdhexaadka ah uma baahna inay kor u qaaddo xannibaadda foornada marka foornada qabowgu bilaabato inay dhalaasho. Birta dhalaalaysa waa lagu shubi karaa, markaa isticmaalku wuu badan yahay Foornada soo noqnoqda ee awoodda ayaa ah mid dabacsan oo habboon; Intaa waxaa dheer, xalka ku jira foornada dhalaalaysa ee soo noqnoqda dhexdhexaadka ah ayaa leh dharbaaxo khafiif ah oo ku yaal qulqulka, taas oo faa’iido u leh daboolka foornada. Sidaa darteed, ka dib horumarinta sahayda tamarta sare iyo raqiis ah ee dhexdhexaadka ah, foornooyinka inta jeer ee dhexdhexaadka ah ayaa weli rajo leh.

(3) Foornada dhalaalka inta jeer ee awoodda

Foornada dhalaalaysa ee inta jeer ee korontadu waa tan ugu dambaysay uguna dhakhsaha badan ee ka dhex jirta dhowr foornood oo dhalaalaysa. Waxaa inta badan loo isticmaalaa dhalaalidda birta iyo birta, gaar ahaan birta birta ah ee xoogga badan iyo birta kabka, iyo sidoo kale kuleylinta, ilaalinta kulaylka iyo hagaajinta ka kooban ee xalka birta kabka; Intaa waxaa dheer, waxaa sidoo kale loo isticmaalaa dhalaalidda biraha aan biraha ahayn sida naxaasta iyo aluminiumka iyo alaabtooda. Haddii awoodda foornada ay yar tahay, maaha mid dhaqaale in la isticmaalo inta jeer ee tamarta. Tusaale ahaan birta shubka ah u qaado. Marka awooddu ay ka yar tahay 750 kg, waxtarka korantada ayaa si weyn u yaraan doona. Foornada dhalaalaysa ee Vacuum induction waxaa loo isticmaalaa in lagu dhalaaliyo alloys kulayl u adkaysta, daawaha birlabeedka, daawaha korantada iyo birta xoogga badan. Dabeecadda nooca foornada noocan ah waa in ay fududahay in la xakameeyo heerkulka foornada, shahaadada vacuum iyo wakhtiga dhalaalka inta lagu jiro habka dhalaalidda, sidaas darteed soo-saarka kharashka ayaa noqon kara mid aad ugu filan. Intaa waxaa dheer, qadarka dheeriga ah ee walxaha daawaha ah ayaa sidoo kale si sax ah loo xakameyn karaa, sidaas darteed waa foorno ku haboon oo lagu dhalaalinayo kuleyliyeyaasha kulaylka u adkaysta iyo qalabka saxda ah ee ka kooban walxaha firfircoon sida aluminium iyo titanium.
