Esithandweni Iziko kanye nekubaluleka kwalo ekukhiqizeni steel

The main sokuncibilikisa iyunithi embonini steel iyona esithandweni evulekile-kwemizi. Yenzelwe steelmaking predetermined amakhemikhali ukwakheka kanye nezici ezithile ngokomzimba futhi lokukhanda. Vula-Iziko esithandweni, okuyinto usebhekene linemibhikisho eziningana zezimboni nezobuchwepheshe, okuvumela ukukhiqizwa eyinkimbinkimbi kunazo lezinsimbi, kuhlanganise elixutshiwe.

Ukuqeda esithandweni kwemizi uhlobo ilangabi ahlula iyunithi okuzivuselela isinyathelo isimiso siqukethe izinto ezilandelayo kwesakhiwo:

• Yokusebenzela kuhlanganise ezingemuva futhi front udonga nophahla.
• Amabhithi ngeziteshi mpo lapho supply fuel futhi emoyeni ingxube ekamelweni ukusebenza kanye ukudedelwa imikhiqizo amandla omlilo therefrom.
• Gas emoyeni slag bamakamelo Iqoqo ekuqongeleleni amafraktjhini ezinkulu encibilika uthuli.
• Regenerators ukuze kulondolozwe izinga lokushisa njalo ngokubeka amalahle uphethiloli gaseous nomoya ingxube nge ukushisa asalile imikhiqizo amandla omlilo ukuthi ophumayo esuka egumbini ukusebenza.
• System shintsho reversibly eziqondisayo valve, eklanyelwe ukushintsha kokuqondisa supply uphethiloli gaseous nomoya ingxube esikhaleni obekusetshenzwa ngalo, uthathe therefrom imikhiqizo amandla omlilo.
• HRSG.
• Ngefasitele.

esithandweni Iziko kuyinto iyunithi ziyalingana, okusho ukwakhiwa efanayo ilungelo layo futhi ohlangothini lwesobunxele eksisi eqonde ngqo phezulu. Kulayishwa izinto zokusetshenziswa ezivezwa ukuvuleka ekhethekile - ukushaja amafasitela, ivaliwe valve, okuyizinto obukhulu steel plate. On kususwa udonga lwangemuva iyunithi athambekele kunesikhala esidayisa okuyothi ngalo steel siphelile kukhishelwa ibe ladle. Phakathi encibilika esidayisa avimbekile caking ubumba refractory, esimelela out at ukukhululwa kwe ukuncibilika kwezinguzunga esiphelele.

Vula-Iziko esithandweni ivumela cishe zonke izinhlobo carbon lezinsimbi nezinhlobo eziningi ingxubevange steel. Kodwa ukusetshenziswa ezahlukene ophethe izinto ezidingekayo ukuze inqubo evulekile-eziko, metal oncibilikisiwe igcwalisa esibalulekile contaminants. Ngisho nengxenyana encane izithasiselo ezifana nesibabule, i-phosphorus, i-arsenic futhi ezinye izici, laba kanjani nesandla ukuwohloka emibi izakhiwo physico-amakhemikhali steel, plastic izinga metal ephansi, lona fragility yayo ngokweqile.

kagesi arc esithandweni eyenzelwe ukuncibilika eliphezulu steel amamaki. Lonke umlando ukuthuthukiswa isiqoqi sama-softwe nelesimbi sehliselwe ukushikashikeka ngenxa izici qualitative of izinsimbi, ekuthuthukiseni izindawo yabo mechanical, ngokomzimba futhi amakhemikhali. Futhi imfihlo esezingeni metal itholakala ebumsulweni nasebunyeni zamakhemikhali. Electrometallurgy kusiza ukuthola okumsulwa amakhemikhali, okusho ukuthi eliphezulu izinsimbi kanye Alloys. Kwenqwaba doped eliphezulu steel Incibilikile e kagesi arc amaziko.
