Indlela yokukhetha igesi yokusika kumatshini wokusika iplasma?

Oomatshini bokusika iplasmangokubanzi babe namandla ombane aphezulu angenamthwalo kunye namandla ombane asebenzayo, kwaye ukunyuka kwamandla ombane kuthetha ukunyuka kwe-arc enthalpy.Ngelixa ukwandisa i-enthalpy, ukunciphisa ububanzi be-jet kunye nokwandisa izinga lokuhamba kwegesi kunokuphucula isantya sokusika kunye nomgangatho wokusika.Amandla ombane aphezulu afuneka xa usebenzisa iigesi ezinamandla amakhulu e-ionization, njengenitrogen, ihydrogen okanye umoya.Zeziphi iingcebiso ezahlukeneyo zokukhetha igesi kunye namanqaku?Makhe sijonge uhlalutyo olucacileyo lwerhasi ngabavelisi bomatshini wokusika iplasma.

I-Hydrogen isetyenziswa ngokubanzi njengegesi encedisayo exutywe nezinye iigesi, kwaye igesi i-H35 yenye yeegesi ezinamandla kakhulu zokusika i-arc ye-plasma.Xa i-hydrogen ixutywe ne-argon, iqhekeza le-hydrogen lihlala li-35%.Ekubeni i-hydrogen inokunyusa kakhulu i-arc voltage, ijethi ye-hydrogen plasma ine-enthalpy ephezulu, kwaye ikhono lokusika i-jet ye-plasma liphuculwe kakhulu.

Ioksijeni inokunyusa isantya sokusika izinto zetsimbi ezithambileyo.Xa usika nge-oksijeni, imodi yokusika ifana kakhulu neyomatshini wokusika umlilo we-CNC.I-high-temperature kunye ne-high-energy plasma arc yenza isantya sokusika ngokukhawuleza, kodwa kufuneka sisetyenziswe ngokubambisana ne-electrodes ephezulu yokumelana ne-oxidation.Yandisa ubomi bee-electrodes.

I-slag eyenziwe ngokusika umoya kunye nokusika i-nitrogen iyafana, kuba umthamo we-nitrogen emoyeni umalunga ne-78%, kwaye kukho malunga ne-21% ye-oksijini emoyeni, ngoko ke isantya sokusika i-carbon steel ephantsi kunye nomoya nayo kakhulu. phezulu, kunye noMoya yeyona gesi isebenzayo inoqoqosho, kodwa ukusika ngomoya wodwa kuya kubangela iingxaki ezifana nokuxhoma kwe-slag, i-kerf oxidation, kunye nokunyuka kwe-nitrogen.Ubomi obuphantsi be-electrode kunye nemilomo buya kuchaphazela ukusebenza kakuhle kunye neendleko zokusika.

Ngaphantsi kwemeko yamandla ombane aphezulu, i-nitrogen plasma arc inozinzo olungcono kunye namandla ejethi aphezulu kune-argon.Ngokomzekelo, xa usika insimbi engenasici kunye ne-nickel-based alloys, kukho i-slag encinci kumgca ophantsi, kwaye i-nitrogen ingasetyenziswa yodwa.Isenokuxutywa nezinye iigesi.I-nitrogen okanye umoya isoloko isetyenziswa njengegesi esebenzayo ekusikeni ngokuzenzekelayo, kwaye ezi zimbini zeegesi ziye zaba yigesi eqhelekileyo yokusika i-carbon steel.

Ukusebenza kwe-argon kuzinzile, kwaye ayifuni nayiphi na isinyithi nakwiqondo lokushisa eliphezulu, kwaye i-nozzle kunye ne-electrode esetyenzisiweyo inobomi obude benkonzo.Nangona kunjalo, i-voltage ye-argon plasma arc iphantsi, i-enthalpy ayiphezulu, kwaye amandla okusika anqunyelwe.Xa kuthelekiswa nokusika komoya, ubukhulu bokusika buya kuncitshiswa malunga ne-25%.Ukongeza, ukuxinana komphezulu wesinyithi esinyibilikisiweyo kuphezulu kakhulu, okumalunga ne-30% ephezulu kunoko kwindawo ye-nitrogen, ngoko kuya kubakho iingxaki zokuxhoma kwe-slag.Nokuba ukusika ngegesi exutyiweyo yezinye iigesi kuya kuthanda ukunamathela kwi-slag.Ke ngoko, i-argon ecocekileyo ayifane isetyenziswe yodwa ukusika iplasma.
