Umahluko phakathi kwesithando sokunyibilikisa induction kunye nesithando sombane se-arc, yeyiphi i-steelmaking engcono? Okuhle nokubi? …

1. Iimpawu ngokubhekiselele kwisakhono sokusulungekisa

Izixhobo zombane ze-arc zingcono kuneziko zokunyibilika kwe-induction malunga nokususwa kwe-phosphorus, isulfure kunye ne-oxygen.

2. Izinga eliphezulu lokubuyisela izinto ze-alloy ezincibilikisiweyo

Imveliso yezinto ezixutywayo ezinyibilikisiweyo nge-intduction melting furnace iphezulu kunombane we-arc furnace. Ukulahleka kwe-volatilization kunye ne-oxidation yezinto zikhulu phantsi kobushushu obuphezulu be-arc. Isantya esivuthayo sokulahleka kwezinto ze-alloy ngexesha lokunyibilika kwi-induction melting furnace iphantsi kunesithando sombane se-arc. Ngokukodwa, isantya sokutshisa ilahleko yezinto ze-alloy kwizinto ezibuyiswayo ezilayishwe kwisithando somlilo ziphezulu kakhulu kunezo ziko lokunyibilikisa induction. Kwi-induction yokunyibilikisa isithando somlilo, inokubuyisela ngokufanelekileyo izinto zokudibanisa kwizinto ezibuyiswayo. Ngethuba lokunyibilika kwesithando sombane se-arc, i-alloying elements kwizinto ezibuyiswayo ziqala ukuxutywa nge-oxidized kwi-slag, kwaye ziyancipha ukusuka kwi-slag ukuya kwintsimbi etyhidiweyo, kwaye izinga lokulahleka kokutshisa linyuka kakhulu. Ireyithi ye-alloy element recovery rate of induction melting furnace iphezulu kakhulu kuneye-arc yombane xa izinto ezibuyiswayo zinyibilikiswa.

3. Ukunyuka kwekhabhoni ephantsi kwintsimbi etyhidiweyo ngexesha lokunyibilika

Isithando somlilo esinyibilikayo se-induction sixhomekeke kumgaqo wokufudumala kwe-induction ukunyibilikisa intlawulo yesinyithi ngaphandle kokunyuka kwekhabhoni yentsimbi etyhidiweyo. Isithando sombane se-arc sixhomekeke kwi-electrode yegraphite ukutshisa intlawulo nge-arc yombane. Emva kokunyibilika, intsimbi etyhidiweyo iya kwandisa ikhabhoni. Ngaphantsi kweemeko eziqhelekileyo, xa unyibilikisa i-high-alloy nickel-chromium steel, ubuncinci bekhabhoni kwi-arc yombane yokunyibilikisa i-arc smelting yi-0.06%, kwaye kwi-induction melting smelting, inokufikelela kwi-0.020%. Ukonyuka kwekhabhoni kwinkqubo yokunyibilikisa i-arc yombane yi-0.020%, kunye ne-induction melting furnace yi-0.010%.

4. I-electromagnetic stirring yensimbi etyhidiweyo iphucula iimeko ze-thermodynamic kunye neziguquguqukayo zenkqubo yokwenza i-steelmaking Iimeko zokunyakaza kwentsimbi etyhidiweyo kwisithando somlilo se-induction ingcono kunezo ze-arc zombane zombane. Isithando sombane se-arc kufuneka sixhotyiswe nge-low-frequency electromagnetic stirrer ukulungiselela le njongo, kwaye isiphumo saso asikabi sihle njengesithando somlilo sokunyibilikisa.

5. Iiparamitha zenkqubo yenkqubo ye-smelting kulula ukuyilawula. Iqondo lobushushu, ixesha lokucoca, ukunyanzeliswa koxinzelelo kunye nobushushu obungaguqukiyo besithando sokunyibilikisa i-induction ngexesha lokunyibilikisa zonke zilunge ngakumbi kuneziko zombane ze-arc kwaye zinokuqhutywa nangaliphi na ixesha. Ngenxa yeempawu ezikhankanywe ngasentla zesithando somlilo sokunyuswa kwe-induction, sithatha indawo ebaluleke kakhulu ekunyibilikeni kweentsimbi eziphezulu ze-alloy kunye ne-alloys.
