Klasifikasi dhasar saka tungku induksi

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.

Tungku leleh dipérang dadi frekuensi dhuwur, frekuensi penengah lan frekuensi daya.

(1) Tungku lebur frekuensi dhuwur

Kapasitas tungku frekuensi dhuwur umume ngisor 50 kg, sing cocog kanggo lebur baja khusus lan paduan khusus ing laboratorium lan produksi skala cilik.

(2) Tungku lebur frekuensi menengah

Kapasitas lan daya tungku peleburan frekuensi penengah luwih gedhe tinimbang tungku frekuensi dhuwur. Utamane digunakake kanggo leburan baja khusus, wesi magnetik lan wesi tembaga. Amarga tungku jinis iki mbutuhake peralatan konversi frekuensi sing larang, mula diowahi dadi tungku tanpa inti frekuensi daya ing sawetara kesempatan sing luwih gedhe. Nanging, dibandhingake karo tungku frekuensi industri, tungku frekuensi penengah uga nduweni fitur unik dhewe. Contone, kanggo tungku kapasitas sing padha, daya input saka tungku frekuensi penengah luwih gedhe tinimbang tungku frekuensi industri, supaya kacepetan leleh luwih cepet. Tungku frekuensi penengah ora perlu ngangkat blok tungku nalika tungku kadhemen wiwit leleh. Ing logam molten bisa diwutahake metu, supaya nggunakake luwih The daya tungku frekuensi fleksibel lan trep; Kajaba iku, solusi ing tungku peleburan frekuensi penengah nduweni scour korek ing crucible, kang ono gunane kanggo lapisan pawon. Mulane, sawise pangembangan sumber daya frekuensi menengah dhuwur lan murah, tungku frekuensi penengah isih janjeni.

(3) Daya tungku leleh frekuensi

Tungku peleburan frekuensi daya paling anyar lan paling cepet berkembang ing antarane sawetara tungku peleburan. Utamane digunakake kanggo peleburan wesi lan baja, utamane wesi wesi lan wesi wesi kanthi kekuatan dhuwur, uga minangka pemanasan, pengawetan panas lan penyesuaian komposisi larutan wesi; Kajaba iku, uga digunakake kanggo peleburan logam non-ferrous kayata tembaga lan aluminium lan wesi. Yen kapasitas tungku cilik, iku ora ekonomi nggunakake frekuensi daya. Njupuk wesi cast minangka conto. Yen kapasitas kurang saka 750 kg, efisiensi listrik bakal mudhun kanthi signifikan. Tungku lebur induksi vakum digunakake kanggo nyawiji wesi tahan panas, wesi magnetik, wesi listrik lan baja kekuatan dhuwur. Karakteristik jinis tungku iki yaiku luwih gampang ngontrol suhu tungku, derajat vakum lan wektu leleh sajrone proses leleh, saengga degassing saka muatan bisa cukup banget. Kajaba iku, jumlah tambahan saka bahan campuran uga bisa dikontrol kanthi akurat, saengga dadi tungku sing luwih cocok kanggo peleburan paduan tahan panas lan paduan presisi sing ngemot unsur aktif kayata aluminium lan titanium.
