Intshayelelo yezitofu:Izitofu luhlobo 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)

Ferrosilicon amasuntswana ayileferrosilicon inoculant, isetyenziselwa ukwenza intsimbi, ukwenza intsimbi,ukuphosa isitofu.

Iimpawu ze-ferrosilicon inoculant:

(1) Ukubunjwa kweengqungquthela ze-ferrosilicon zifana kwaye ulwahlulo luncinci;

(2) ubukhulu be-particle ye-ferrosilicon bufana, akukho mgubo ococekileyo, kunye nefuthe le-inoculation lizinzile;

(3) Impembelelo ye-inoculation yeengqungquthela ze-ferrosilicon inamandla kuneengqungquthela eziqhelekileyo ze-ferrosilicon, kwaye ukuthambekela kokuvelisa i-slag kuncinci;

(4) ukwandisa ixesha lokungunda 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 ngokuhambelana nomlinganiselo wemfuno, kwaye emva koko ngokusebenzisa i-steelmaking yesithando sobushushu esiphezulu kwi-bulk metallurgical materials.It 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 esingwevu 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, phucula ukufana kwecandelo, ukunciphisa ukuthambekela kokunciphisa kunye nokukhululeka.

I-5, ukubunjwa kweekhemikhali kuzinzile, i-granularity yokucubungula ifana, ukubunjwa kunye nokuphambuka komgangatho kuncinci.

6. Indawo yokunyibilika iphantsi (ngaphantsi kwe-1300 °), kwaye kulula ukufunxa kunye nokunyibilika xa utofa, kwaye i-scum imbalwa kakhulu.
