Intshayelelo yezitofu:Izitofuluhlobo lunokukhuthaza i-graphitization, ukunciphisa ukuthambekela komlomo omhlophe, ukuphucula i-morphology kunye nokusabalalisa i-graphite, ukwandisa inani leqela le-eutectic, ukucokisa isakhiwo se-matrix.
Inoculant yeparticle yeFerrosilicon (isitofu esikhethekileyo sokugalela)
Ferrosiliconamasuntswana ayile ferrosilicon inoculant, isetyenziselwa ukwenza intsimbi, ukwenza intsimbi,ukuphosaisitofu.
Iimpawu ze-ferrosilicon inoculant:
(1) Ukubunjwa kweengqungquthela ze-ferrosilicon zifana kwaye ulwahlulo luncinci;
(2) ubukhulu becala le-ferrosilicon lifanayo, akukho mgubo ococekileyo, kwaye umphumo we-inoculation uzinzile;
(3) Impembelelo ye-inoculation yeengqungquthela ze-ferrosilicon zinamandla kuneengqungquthela eziqhelekileyo ze-ferrosilicon, kwaye ukuthambekela kokuvelisa i-slag kuncinci;
(4) bandise ubomi besikhunta kunye nokunciphisa iziphene ezingaphezulu;
(5) Nciphisa umngxuma wepinki, uphucule umgangatho womphezulu wombhobho wokuphosa, kwaye uphucule izinga lokupasa konikezelo lokuqala;
(6) ukuphelisa i-microshrinkage ebonakalayo kunye nokuphucula ukusebenza komatshini wokuphosa.
I-silica-barium (i-calcium) inoculant
I-silica-barium inoculant,(BA-SI)Ingaba iisiliconumgubo kunye ne-barium powder ngokuxuba ngokomlinganiselo wemfuno, kwaye emva koko ngokusebenzisa i-steelmaking yeziko lobushushu eliphezulu kwizinto ezininzi ze-metallurgical.Luhlobo lokudibanisa kwinkqubo yokuphosa ye-Foundry, enokukhuthaza i-graphitization, ukunciphisa ukuthambekela komhlophe. umlomo, ukuphucula i-morphology kunye nokusabalalisa kwegraphite, ukwandisa inani lamaqela e-eutectic, kunye nokucoca isakhiwo se-matrix.
I-silica-bariumumsebenzi wokutofa:
I-1, yandisa kakhulu i-core graphitization, coca i-graphite, ikhuthaze isinyithi esimpunga ukufumana i-graphite yohlobo lwe-A, ukuphucula amandla, kuba i-ductile iron inokwenza i-graphite kwi-ductile iron icolise, ijikeleze, iphucule ibakala le-spheroidization.
2. Inokunciphisa ngokufanelekileyo idigri ye-supercooling yentsimbi etyhidiweyo, ikhuthaze imvula yegraphite, inciphise kakhulu ukuthambekela komlomo omhlophe, ukunciphisa ubunzima obunxulumeneyo, kunye nokuphucula ukusebenza komatshini wokuphosa.
3. Ubuchule obunamandla bokuchasana nokudodobala koqoqosho, ixesha lokuchasana nokudodobala koqoqosho ngamaxesha angama-275 isilicon, inani le-silicon bariumisitofuingaphantsi kwesiqingatha se-75 inoculant ye-ferrosilicon, ngelixa ikhusela ukudodobala kwe-spheroidification ehambelanayo.
I-4, ubuthathaka bodonga luncinci, ukuphucula ukufana kwecandelo, ukunciphisa ukuthambekela kokunciphisa kunye nokukhululeka.
I-5, ukubunjwa kweekhemikhali kuzinzile, i-granularity yokucubungula ifana, ukubunjwa kunye nokuphambuka komgangatho kuncinci.
6. Iqondo lokunyibilika liphantsi (ngaphantsi kwe-1300 °), kwaye kulula ukufunxa kunye nokunyibilika xa utofa, kwaye i-scum imbalwa kakhulu.
