Gulu loyambira la ng’anjo yolowera

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.

Ng’anjo yosungunuka imagawidwa mufupipafupi, mafupipafupi apakati ndi mafupipafupi amphamvu.

(1) Ng’anjo yosungunuka kwambiri

Mphamvu ya ng’anjo yothamanga kwambiri nthawi zambiri imakhala pansi pa 50 kg, yomwe ili yoyenera kusungunula zitsulo zapadera ndi ma alloys apadera m’ma laboratories ndi kupanga pang’ono.

(2) Ng’anjo yapakatikati yosungunuka

Mphamvu ndi mphamvu ya ng’anjo yapakatikati yosungunula ndi yayikulu kuposa ya ng’anjo yothamanga kwambiri. Amagwiritsidwa ntchito makamaka kusungunula zitsulo zapadera, maginito aloyi ndi ma aloyi amkuwa. Chifukwa ng’anjo yamtunduwu imafuna zida zosinthira pafupipafupi, yasinthidwa kukhala ng’anjo yamagetsi yopanda mphamvu nthawi zina zazikulu. Komabe, poyerekeza ndi ng’anjo yamagetsi yamagetsi, ng’anjo yapakatikati yapakati imakhalanso ndi mawonekedwe ake apadera. Mwachitsanzo, kwa ng’anjo ya mphamvu yomweyo, mphamvu athandizira wa wapakatikati pafupipafupi ng’anjo ndi lalikulu kuposa mafakitale pafupipafupi ng’anjo, kotero kusungunuka liwiro mofulumira. Ng’anjo yapakatikati ya ng’anjo siyenera kukweza chipika cha ng’anjo pamene ng’anjo yozizira ikuyamba kusungunuka. Chitsulo chosungunula chikhoza kutsanulidwa, kotero ntchitoyo imakhala yochuluka Mng’anjo yamagetsi yamagetsi imasinthasintha komanso yosavuta; Komanso, yankho mu wapakatikati pafupipafupi smelting ng’anjo ali mkuwala scour pa crucible, amene amapindulitsa pa ng’anjo akalowa. Chifukwa chake, pambuyo pakukula kwamagetsi apamwamba komanso otsika mtengo wapakati pafupipafupi, ng’anjo zapakatikati zimalonjezabe.

(3) Ng’anjo yosungunuka yamagetsi yamagetsi

Ng’anjo yosungunula yamagetsi ndiyo yaposachedwa kwambiri komanso yofulumira kwambiri pakati pa ng’anjo zingapo zosungunulira. Amagwiritsidwa ntchito kwambiri posungunula chitsulo chosungunula ndi chitsulo, makamaka chitsulo chosungunuka champhamvu kwambiri ndi chitsulo chosungunula, komanso kutentha, kuteteza kutentha ndi kusintha kwapangidwe kwa chitsulo chosungunuka; Kuonjezera apo, amagwiritsidwanso ntchito kusungunula zitsulo zopanda chitsulo monga mkuwa ndi aluminiyamu ndi ma alloys awo. Ngati mphamvu ya ng’anjo ndi yaying’ono, sikuli ndalama kugwiritsa ntchito mafupipafupi a mphamvu. Tengani chitsulo chosungunula mwachitsanzo. Pamene mphamvu ili yosakwana 750 kg, mphamvu yamagetsi idzachepa kwambiri. Vuto la ng’anjo ya vacuum induction melting limagwiritsidwa ntchito kusungunula ma alloys osagwira kutentha, maginito aloyi, ma aloyi amagetsi ndi zitsulo zolimba kwambiri. Makhalidwe a mtundu wa ng’anjo iyi ndikuti ndi kosavuta kulamulira kutentha kwa ng’anjo, digiri ya vacuum ndi nthawi yosungunuka panthawi yosungunuka, kotero kuti kutulutsa mpweya wamoto kungakhale kokwanira kwambiri. Kuphatikiza apo, kuchuluka kwa zinthu za aloyi kumatha kuwongoleredwa bwino, kotero ndi ng’anjo yoyenera kusungunula ma aloyi osagwira kutentha ndi ma aloyi olondola okhala ndi zinthu zogwira ntchito monga aluminium ndi titaniyamu.
