Okokuqala, izinto eziphambili ezichaphazela umphumo wonyango
Iziqwenga zemibhobho kaMary ezijongene nobungakanani obufanelekileyo ngenxa yoluhlu lwemetamorphism element ifuna emxinwa kakhulu, kwaye ngaloo ndlela kunzima ukuzinzisa kune-ductile iron.Oku kufuna ukuba iimeko zenkqubo efanelekileyo kufuneka zizame ukwenza ukuguquguquka okuncinci.Isiphumo sonyango lwezifakelo zemibhobho yentsimbi enyibilikayo yimiba emikhulu yenkqubo ikakhulu yile miba ilandelayo.
I-1, umxholo wesulfure wentsimbi yokuqala eshushu
Ukuwohloka kokusetyenziswa kwesulfure.Inamandla kakhulu esinyithi eshushu sulfur kunye ne-magnesium ephezulu, i-cerium, i-calcium, kukho i-modifier eninzi i-vulcanized kwi-slag, ngaloo ndlela inciphisa amandla okubangela ukuwohloka konyango olungaphumeleli.Ngoko ke, ekuveliseni izifakelo zemibhobho yentsimbi ethambileyo kufuneka zizame ukusebenzisa intsimbi yehagu enesalfure ephantsi kunye necoke.Iimeko, thatha amanyathelo kwangethuba ukuze desulphurization kuyingenelo.Oku akuthethi ukuba ngomxholo wesulfure ophezulu wentsimbi etyhidiweyo ayinakusetyenzwa ngempumelelo izifakelo zemibhobho yentsimbi ethambileyo.Iifektri ezininzi zasekhaya nezangaphandle ezinomxholo wesulfure ukuya kuthi ga kwi-0.06-0.08% yecupola yentsimbi eshushu inokuveliswa ngokuzinzileyo imibhobho yentsimbi ethambileyo, kodwa ukuwohloka kwealloyi kuya kusetyenziswa kwisixa esingaphezulu.Ulwazi ngamava kunye 0.07-0.13% imveliso yesalfure eshushu yesinyithi yentsimbi ehlanganisiweyo yegraphite ukuba phantsi kweemeko ezithile, ezifana ne-titanium yokwandisa umda wesenzo ukusuka ekusebenziseni i-anti-ball effect yesulfure.Nangona kunjalo, ubungakanani besulfure luzinzile ukusetyenzwa kwemibhobho yentsimbi ethambileyo kunye neemfuno eziyimfuneko.
2, ubushushu bokusebenza kwentsimbi etyhidiweyo
Xa intsimbi enyibilikisiweyo unyango ubushushu obuphantsi Gao waba nefuthe elibonakalayo izinga lokufunxa ingxubevange, ingakumbi vermicularizing magnesium-based ngakumbi.Okukhona iqondo lobushushu liphezulu, kokukhona ukubilisa igesi ye-magnesium enobundlobongela, ukutshisa kokukhona ngaphantsi, ezinye ziphantsi kangangoko ukuze iqondo lobushushu lokucubungula ngokunjalo.Uxwebhu luchaza xa kusetyenziswa i-magnesium titanium composite modifier processing izifakelo zentsimbi ezithambileyo, iimpembelelo zobushushu bonyango olwahlukileyo ekusebenzeni konyango.Ukulungiswa kwi-1400 ℃, igraphite efana nentshulube ngaphezu kwe-95%, ibhola kunqabile;kunyango lwe-1280 ℃, ngaphezu kwesiqingatha samaqhuqhuva egraphite.Isixa se-alloy siyafana, iqondo lokushisa lokulungiswa kwesantya esikhulu sokufunxa esibonakalayo.
Kwimveliso yokwenyani, iqondo lobushushu kufuneka liqwalaselwe ukumisela inkqubo yokugalela iimfuno zobushushu.Nangona kunjalo, iqondo lokushisa lokucubungula kufuneka libe lizinzile ngokusemandleni, ukuba ukuguquguquka kweqondo lokushisa kukhulu, isixa kufuneka silungiswe i-alloy, ngaphandle koko kunzima ukuqinisekisa umgangatho wonyango.
I-vermicularizing esekwe emhlabeni enqabileyo, iqondo lokushisa liphezulu Ngokufanelekileyo, iqondo lobushushu lisezantsi kakhulu akukho lula nokuba, akukho nokuba i-alloy enyibilike ngokupheleleyo, ngaloo ndlela ichaphazela isiphumo sonyango.
3. Ukulungiswa kwemisebenzi
Ekubeni inkqubo yokungena yenkqubo ngenxa yokuguquguquka kwimpendulo tangled enovakalelo, ngaloo ndlela ifuna umsebenzi ucetyiswa ukuba ichaneke ngokungqongqo.Ukufana kwe-alloy composition, i-alloy egubungela ityala, i-quantitative and iron alloys, i-slag slag kunye namanye amanyathelo, afana nefuthe elithe ngqo kwisiphumo sonyango.
