Ulwahlulo olusisiseko lwe-furnace 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.

Isithando somlilo sokunyibilika sahlulwe saba ngamaza aphezulu, amaza aphakathi kunye namaza ombane.

(1) Isithando somlilo esinyibilikayo esinesantya esiphezulu

Umthamo we-furnace ye-high-frequency jikelele ungaphantsi kwe-50 kg, efanelekileyo yokunyibilikisa isinyithi esikhethekileyo kunye ne-alloys ezikhethekileyo kwiibhubhoratri kunye nemveliso encinci.

(2) Iziko lokunyibilikisa eliphakathi

Umthamo kunye namandla e-intermediate frequency smelting furnace inkulu kuneyo ye-high frequency smelting. Ikakhulu isetyenziselwa ukunyibilikisa iintsimbi ezikhethekileyo, iialloyi ezinomagnetic kunye nealloys zethusi. Ngenxa yokuba olu hlobo lwesithando somlilo lufuna izixhobo ezibiza imali eninzi zoguqulo, iye yatshintshelwa kwisithando somlilo esingenaziko ngamaxesha athile amakhulu. Nangona kunjalo, xa kuthelekiswa ne-furnace ye-industrial frequency, isithando somlilo esiphakathi sineempawu zayo ezizodwa. Umzekelo, kwisithando somlilo somthamo ofanayo, amandla okufakelwa kwesithando somlilo esiphakathi sikhulu kuneso somlilo we-industrial frequency, ngoko ke isantya sokunyibilika sikhawuleza. Isithando somlilo esiphakathi akufuneki siphakamise ibhloko yesithando somlilo xa isithando somlilo esibandayo siqala ukunyibilika. Isinyithi esityhidiweyo sinokugalelwa, ngoko ke ukusetyenziswa kuninzi I-furnace yamandla aphindaphindiweyo iyaguquguquka kwaye ilungele; ukongeza, isisombululo kwi-intermediate frequency smelting furnace ine-smelting scour kwi-crucible, enenzuzo kwi-furnace lining. Ke ngoko, emva kophuhliso lwamandla aphezulu kunye nonikezelo lwamandla oluphakathi olusezantsi, iziko eliphakathi lisathembisa.

(3) Isithando sokunyibilikisa samandla

Iziko lokunyibilikisa lamandla lelona xesha litsha kwaye lelona likhawulezayo phakathi kwezitofu ezininzi zokunyibilikisa. Isetyenziselwa ikakhulu ukunyibilikiswa kwentsimbi kunye nentsimbi, ngakumbi amandla aphezulu aphezulu kunye ne-alloy cast iron, kunye nokufudumeza, ukugcinwa kobushushu kunye nokulungelelaniswa kokwakheka kwesisombululo sentsimbi; Ukongeza, ikwasetyenziselwa ukunyibilikiswa kweentsimbi ezingezizo i-ferrous ezifana nobhedu kunye ne-aluminiyam kunye neengxube zazo. Ukuba umthamo wesithando somlilo uncinci, akukho qoqosho ukusebenzisa i-frequency yamandla. Thatha intsimbi etyhidiweyo njengomzekelo. Xa umthamo ungaphantsi kwe-750 kg, ukusebenza kombane kuya kuncipha kakhulu. I-vacuum induction melting furnace isetyenziselwa ukunyibilikisa i-alloys ekwazi ukumelana nobushushu, i-alloys magnetic, i-alloys yombane kunye nentsimbi ephezulu. Isici solu hlobo lwesithando somlilo kukuba kulula ukulawula ukushisa kwesithando somlilo, i-vacuum degree kunye nexesha lokunyibilika ngexesha lokunyibilika, ngoko ke ukuchithwa kwentlawulo kunokwanela kakhulu. Ukongeza, isixa esongezelelweyo semathiriyeli ye-alloy sinokulawulwa ngokuchanekileyo, ke liziko elifanelekileyo ngakumbi lokunyibilikisa i-alloys ukumelana nobushushu kunye neealloyi ezichanekileyo eziqulethe izinto ezisebenzayo ezifana ne-aluminiyam kunye ne-titanium.
