Basic classification ntawm induction rauv

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.

Lub qhov cub melting yog muab faib ua ntau zaus, nruab nrab zaus thiab lub zog zaus.

(1) High-frequency melting rauv

Lub peev xwm ntawm lub tshuab hluav taws xob siab feem ntau yog qis dua 50 kg, uas yog tsim rau smelting tshwj xeeb hlau thiab alloys tshwj xeeb hauv cov chaw soj nstuam thiab cov khoom me me.

(2) Intermediate zaus melting rauv

Lub peev xwm thiab lub zog ntawm qhov nruab nrab zaus smelting rauv yog qhov loj dua li ntawm lub tshuab hluav taws xob siab. Feem ntau yog siv rau smelting tshwj xeeb steels, sib nqus alloys thiab tooj liab alloys. Vim tias qhov cub hluav taws xob zoo li no yuav tsum tau siv cov khoom siv hluav taws xob ntau zaus, nws tau hloov mus rau lub tshuab hluav taws xob tsis muaj hluav taws xob hauv qee lub sijhawm muaj peev xwm loj dua. Txawm li cas los xij, piv nrog rau lub tshuab hluav taws xob ntau zaus, qhov nruab nrab zaus qhov cub kuj muaj nws tus kheej tshwj xeeb. Piv txwv li, rau lub cub tawg ntawm tib lub peev xwm, lub hwj chim input ntawm lub nruab nrab zaus rauv yog loj dua li ntawm cov muaj zaus rauv, yog li ntawd lub melting ceev yog ceev. Lub tshuab hluav taws xob nruab nrab tsis tas yuav nqa lub cub tawg thaum lub qhov cub txias pib yaj. Cov hlau molten tuaj yeem nchuav tawm, yog li kev siv ntau dua Lub tshuab hluav taws xob zaus hloov tau yooj yim thiab yooj yim; Nyob rau hauv tas li ntawd, cov tshuaj nyob rau hauv nruab nrab zaus smelting rauv muaj ib tug sib zog scour ntawm lub crucible, uas yog zoo rau lub qhov cub hauv ob sab phlu. Yog li ntawd, tom qab kev loj hlob ntawm high-power thiab pheej yig intermediate zaus fais fab mov, intermediate zaus furnaces tseem pheej.

(3) Lub zog zaus melting rauv

Lub hwj chim zaus smelting rauv yog qhov tseeb thiab kev txhim kho sai tshaj plaws ntawm ntau lub qhov cub smelting. Nws yog tsuas yog siv rau smelting ntawm cam khwb cia hlau thiab hlau, tshwj xeeb tshaj yog high-strength cam khwb cia hlau thiab alloy cam khwb cia hlau, raws li zoo raws li lub cua sov, tshav kub preservation thiab muaj pes tsawg leeg ntawm cov cam khwb cia hlau tov; Tsis tas li ntawd, nws kuj yog siv rau smelting ntawm non-ferrous hlau xws li tooj liab thiab txhuas thiab lawv cov alloys. Yog tias qhov cub muaj peev xwm me me, nws tsis yog kev lag luam los siv lub zog zaus. Coj cam khwb cia hlau ua piv txwv. Thaum lub peev xwm tsawg dua 750 kg, qhov hluav taws xob efficiency yuav txo qis. Lub tshuab nqus tsev induction melting rauv yog siv los yaj tshav kub-resistant alloys, magnetic alloys, hluav taws xob alloys thiab high-strength steels. Cov yam ntxwv ntawm lub cub tawg no yog tias nws yooj yim dua los tswj lub qhov cub kub, lub tshuab nqus tsev kawm ntawv thiab lub sijhawm melting thaum lub sij hawm melting, yog li lub degassing ntawm tus nqi yuav txaus txaus. Tsis tas li ntawd, qhov sib ntxiv ntawm cov khoom siv hlau kuj tuaj yeem raug tswj kom raug, yog li nws yog qhov tsim nyog rau qhov cub rau smelting tshav kub-resistant alloys thiab precision alloys uas muaj cov ntsiab lus tseem ceeb xws li txhuas thiab titanium.
