Iyini i-inoculant?
Inoculant iyingxubevangei-additive esetshenziselwa ukuthuthukisa izakhiwo ze-cast iron.
Umsebenzi oyinhloko we-inoculant ukuthuthukisa amandla, ukuqina nokumelana nokugqoka kwensimbi ekhonjiwe ngokukhuthaza i-graphitization, ukunciphisa ukuthambekela kokuba mhlophe, ukuthuthukisa i-morphology nokusatshalaliswa kwe-graphite, ukwandisa inani lamaqembu e-eutectic, nokucwenga isakhiwo se-matrix.e.
Ama-inoculants avame ukusetshenziswa ohlelweni lokujova lokukhiqizwa kwensimbi ekhonjiwe.Zenezelwa ensimbi encibilikisiweukuwasabalalisa ngokulinganayo ensimbi ekhonjiwe, ngaleyo ndlela kuthuthukiswe izakhiwo ze-cast iron.Uhlobo nokwakheka kwezitofu ziyahlukahluka kuye ngohlobo lwensimbi ekhonjiwe kanye nezidingo zokukhiqiza.Ukukhethwa kwama-inoculant afanelekile kubaluleke kakhulu ekuthuthukiseni ukusebenza kwe-cast iron.
Ngaphezu kwalokho, inoculanI-ts ingasetshenziswa futhi ekwelapheni kwe-inoculation yezinto zensimbi ukuze kuthuthukiswe ukusebenza kwazo kanye nesakhiwo senhlangano.
Yiziphi izinhlobo zokujovaLapho?
Izinhlobo zokujova ziyahlukahluka kuye ngezithako kanye nokusetshenziswa kwazo.Nazi ezinye izinhlobo ezivamile zokujova:
1. Inoculan esekelwe ku-silicont: ikakhulukazi i-ferrosilicon, okuhlanganisa i-calcium silicon, i-barium silicon, njll. Lolu hlobo lwe-inoculant lusebenza ngokuyinhloko ukukhuthaza i-graphitization, ukunciphisa ukuthambekela kokuba mhlophe, ukuthuthukisa i-morphology nokusabalalisa kwe-graphite, ukwandisa inani lamaqembu e-eutectic, ukucwenga isakhiwo se-matrix, njll.
2. I-ino esekelwe kwikhabhoniama-culants: ikakhulukazi ikhabhoni, okuhlanganisa izijovo ezinekhabhoni ephansi kanye nezijovo ezinekhabhoni ephezulu.Lolu hlobo lwe-inoculant luthuthukisa izakhiwo ze-cast iron ngokuyinhloko ngokulawula okuqukethwe kwekhabhoni.
3. I-inoculant yomhlaba engavamile: ikakhulukazi izakhi zomhlaba ezingavamile, njenge-cerium, i-lanthanum, njll. Lolu hlobo lwe-inoculant lunemisebenzi yokuthuthukisa i-graphitization, ukucwenga okusanhlamvu, nokuthuthukisa amandla, ukuqinad ukugqoka ukumelana nensimbi.
4. Isitofu esihlanganisiwe: isitofu esakhiwe ngezinto eziningi, njenge-calcium silicon, i-barium silicon, umhlaba ongavamile, njll. Lolu hlobo lwe-inoculant lunomphumela wezakhi eziningi futhi lungathuthukisa ngokugcwele izakhiwo ze-cast iron.
Ungayisebenzisa kanjani i-inoculant
Ukusetshenziswa kwe-inoama-culants ikakhulukazi ancike ohlotsheni oluthile lwensimbi ekhonjiwe kanye nezidingo zokukhiqiza.Nazi ezinye zezindlela ezijwayelekile zokusebenzisa ama-inoculant:
Inoculation ku-bag: Faka isitofu esikhwameni, bese uthela insimbi encibilikisiwe ukuze inyibilike ngokulinganayo bese uyithela.
I-surface inoculation: Fafaza isitofu ngokulinganayo phezu kwensimbi encibilikisiwe ukuze isebenze ngokushesha.
Inoculant spraying: Ngemva kokuhlambulula i-inoculant ngokulingana, yifafaze ebusweni bomgodi wokubunjwa ngesibhamu sokufutha ukuze singene esikhunjeni.
Ukujova ngesikhathi sokuthela: Faka isitofu ku-tundish, bese insimbi encibilikisiwe igelezela emgodini wesikhunta ngesikhathi sokuthululwa ukuze idlale indima yokudla.
