Chii chinonzi inoculant?
Inoculant is alloyadditive inoshandiswa kuvandudza zvinhu zvesimbi yakakandwa.
Basa guru reinoculant nderekuvandudza simba, kuoma uye kupfeka kusagadzikana kwesimbi yakakandwa nekusimudzira graphitization, kuderedza maitiro ekuchena, kuvandudza morphology uye kuparadzirwa kwegraphite, kuwedzera nhamba yemapoka eutectic, nekugadzirisa matrix structur.e.
Inoculants inowanzoshandiswa mukuita inoculation yekugadzirwa kwesimbi yakakandwa.Vanowedzerwa musimbi yakanyungudutswakuti vagovanise zvakaenzana musimbi yakakandwa, nokudaro vachivandudza zvinhu zvesimbi yakakandwa.Mhando uye kuumbwa kweinoculants kunosiyana zvichienderana nerudzi rwesimbi yakakandwa uye zvinodiwa zvekugadzira.Kusarudzwa kweanoculants akakodzera kunokosha zvikuru pakuvandudza kushanda kwesimbi yakakandwa.
Mukuwedzera, inoculants inogonawo kushandiswa mukurapa inoculation yezvinhu zvesimbi kuvandudza mashandiro avo uye chimiro chesangano.
Ndeapi marudzi einoculantsikoko?
Mhando dzeinoculants dzinosiyana zvichienderana nemishonga yavo uye kushandiswa.Heano mamwe marudzi akajairika einoculants:
1. Silicon-based inoculant: kunyanya ferrosilicon, kusanganisira calcium silicon, barium silicon, etc. Iyi inoculant inonyanya kushanda kukurudzira graphitization, kuderedza tsika yekuchenesa, kuvandudza morphology uye kuparadzirwa kwegraphite, kuwedzera nhamba yemapoka eutectic, kunatsa matrix maitiro, etc.
2. Carbon-based inoculants: kunyanya kabhoni, kusanganisira yakaderera-kabhoni inoculants uye high-carbon inoculants.Iyi mhando yeinoculant inovandudza zvinhu zvesimbi yakakandwa zvakanyanya nekudzora kabhoni.
3. Rare earth inoculant: zvikuru zvisingawanzo itika pasi pano, zvakadai secerium, lanthanum, etc. Iyi inoculant ine mabasa ekusimudzira graphitization, kunatsa zviyo, nekuvandudza simba, kusimba uyed kupfeka kusagadzikana kwesimbi yakakandwa.
4. Compound inoculant: inoculant inoumbwa nezvinhu zvakawanda, zvakadai se calcium silicon, barium silico.n, rare earth, etc. Mhando iyi yeinoculant ine simba rezvinhu zvakawanda uye inogona kunyatsogadzirisa zvinhu zvesimbi yakakandwa.
Nzira yekushandisa inoculant
Kushandiswa kweinoma culants anonyanya kuenderana nemhando yesimbi yakakandwa uye zvinodiwa zvekugadzira.Dzinotevera ndedzimwe nzira dzakajairika dzekushandisa inoculants:
Inoculation mu bag: Isa inoculant mubhegi, wozodira musimbi yakanyungudutswa kuti inyunguduke zvakaenzana wodira.
Surface inoculation: Mwaya inoculant zvakaenzana pamusoro pesimbi yakanyungudutswa kuti ishande nekukurumidza.
Inoculant spraying: Mushure mekudzikisa inoculant muchiyero, ipfapfaidze pamusoro pevhu rekugadzira mold kuburikidza nepfuti yekupfapfaidza kuitira kuti ipinde muforoma.
Inoculation panguva yekudira: Isai inoculant mu tundish, uye simbi yakanyunguduka inoyerera ichipinda mumhango ye mold panguva yekudira kuti iite basa rekudyisa.
