Klasifikasi dasar 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.

The tungku lebur dibagi kana frékuénsi luhur, frékuénsi panengah jeung frékuénsi kakuatan.

(1) tungku lebur frékuénsi luhur

Kapasitas tungku frékuénsi luhur umumna handap 50 kg, nu cocog pikeun smelting baja husus sarta alloy husus di laboratorium jeung produksi skala leutik.

(2) tungku lebur frékuénsi panengah

Kapasitas sareng kakuatan tungku smelting frékuénsi panengah langkung ageung tibatan tungku frekuensi tinggi. Utamana dipaké pikeun smelting steels husus, alloy magnét sarta alloy tambaga. Kusabab jenis ieu tungku merlukeun parabot konversi frékuénsi mahal, éta geus switched kana tungku coreless frékuénsi kakuatan dina sababaraha kasempetan kapasitas badag. Sanajan kitu, dibandingkeun jeung tungku frékuénsi industri, tungku frékuénsi panengah ogé mibanda fitur unik sorangan. Salaku conto, pikeun tungku kapasitas anu sami, kakuatan input tungku frékuénsi panengah langkung ageung tibatan tungku frekuensi industri, janten laju lebur langkung gancang. Tungku frékuénsi panengah henteu kedah ngangkat blok tungku nalika tungku tiis mimiti ngalembereh. logam molten bisa dituang kaluar, jadi pamakéan leuwih The tungku frékuénsi kakuatan anu fléksibel tur merenah; Sajaba ti éta, leyuran dina tungku smelting frékuénsi panengah ngabogaan scour torek dina crucible nu, nu mangpaat pikeun pinding tungku. Ku alatan éta, sanggeus ngembangkeun-kakuatan luhur sarta mirah suplai kakuatan frékuénsi panengah, tungku frékuénsi panengah masih ngajangjikeun.

(3) tungku lebur frékuénsi kakuatan

The tungku smelting frékuénsi kakuatan nyaéta panganyarna na panggancangna ngembang diantara sababaraha furnaces smelting. Ieu utamana dipaké pikeun smelting tina beusi tuang jeung waja, utamana-kakuatan tinggi tuang beusi jeung alloy beusi tuang, kitu ogé pemanasan, pelestarian panas sarta adjustment komposisi leyuran beusi tuang; Sajaba ti éta, ogé dipaké pikeun smelting logam non-ferrous kayaning tambaga jeung aluminium sarta alloy maranéhanana. Lamun kapasitas tungku leutik, teu ekonomis ngagunakeun frékuénsi kakuatan. Candak beusi tuang sabagé conto. Nalika kapasitasna kirang ti 750 kg, efisiensi listrik bakal turun sacara signifikan. Tungku lebur induksi vakum dipaké pikeun ngalembereh alloy tahan panas, alloy magnét, alloy listrik jeung steels-kakuatan tinggi. Ciri tina tipe tungku ieu téh nya éta leuwih gampang pikeun ngadalikeun hawa tungku, gelar vakum sarta waktu lebur salila prosés lebur, jadi degassing tina muatan tiasa pisan cukup. Sajaba ti éta, jumlah tambahan tina bahan alloy ogé bisa akurat dikawasa, jadi eta mangrupakeun tungku leuwih cocog pikeun smelting alloy panas-tahan jeung alloy precision ngandung unsur aktif kayaning aluminium sarta titanium.
