72% thiab 75% ferrosilicon yog ob hom kev siv ntau tshaj plaws ntawm ferrosilicon hauv khw. Lawv lub ntsiab sib txawv yog nyob rau hauv lawv cov ntsiab lus silicon.

Ferrosilicon 72: Silicon cov ntsiab lus 72% -74%, pheej yig dua. Haum rau cov pa roj carbon steel thiab cov khoom siv zoo tib yam.

Ferrosilicon 75: Silicon cov ntsiab lus 74%-80%, kim dua. Haum rau alloy steel thiab high-zoo castings.

Ntau lub sij hawm ntev - cov neeg siv khoom khaws cia ob qho tib si ntawm tes: 75% rau siab - cov khoom xav tau thiab 72% rau cov khoom qis dua - cov khoom xav tau. Qhov no ua kom zoo thaum tswj cov nqi.

Cov khoom siv

Steelmaking kev lag luam

Deoxidizer:

Ferro silicon 72% alloy thiab Ferro silicon 75% alloy feem ntau yog sivcov deoxidizers. Cov pa oxygen hauv cov hlau molten yuav ua rau muaj qhov tsis xws luag xws li pores thiab looseness hauv cov hlau. Cov silicon hauv lawv muaj kev sib raug zoo nrog cov pa oxygen thiab tuaj yeem deoxidized sai sai los tsim silica thiab nkag mus rau hauv slag, txhim kho cov purity ntawm cov hlau. Yog tias ntxiv rau theem tom ntej ntawm kev hloov pauv steelmaking, cov pa oxygen hauv cov hlau tuaj yeem txo tau . 75# FeSi muaj cov ntsiab lus silicon siab thiab muaj peev xwm deoxidizing me ntsis dua Ferrosilicon 72%. Cov hom hlau uas xav tau siab purity ntawm molten steel yuav nyiam Ferrosilicon 75%.

Alloying agent:

Ntxiv lialloying tus neeg sawv cevrau steel los txhim kho kev ua haujlwm. Silicon yog yaj nyob rau hauv ferrite los tsim cov khoom siv ntxiv zog, uas txhim kho lub zog, hardness thiab elastic txwv ntawm hlau. FeSi 75% feem ntau yog siv rau hauv kev tsim cov hlau tshwj xeeb xws li lub caij nplooj ntoos hlav steel thiab tshav kub-cov hlau tsis muaj zog. Vim nws cov ntsiab lus silicon siab, FeSi 75 # yuav ua tau zoo dua hauv kev txhim kho qee yam khoom ntawm cov hlau.

Kev lag luam Foundry

Inoculant:

Siv los ua ib qho inoculant hauv cam khwb cia hlau tsim los txhawb graphitization, tiv thaiv cov pob dawb, ua kom cov graphite zoo ib yam thiab zoo, thiab txhim kho cov khoom siv ntawm cov hlau cam khwb cia. Ob leeg ferro silicon 72 alloy thiab ferro silicon 75 alloy yog qhov tsim nyog, tab sis 75% ferrosilicon muaj cov ntsiab lus ntawm silicon siab thiab tej zaum yuav raug ntxiv rau me me, nyob ntawm seb cov hlau cam khwb cia thiab kev ua tau zoo.

Kho qhov muaj pes tsawg leeg:

Siv los kho cov ntsiab lus ntawm silicon hauv cov hlau molten kom ua tau raws li qhov xav tau ntawm cov khoom sib txawv. Cov castings sib txawv muaj cov kev xav tau sib txawv rau cov ntsiab lus silicon, uas tuaj yeem hloov kho los ntawm kev ntxiv FeSi 72 # lossis FeSi 75 # kom ruaj khov thiab ua haujlwm zoo ntawm cov castings.

FAQ

Q: Ntau npaum li cas 72% ferrosilicon nqi piv rau 75% ferrosilicon? Kuv yuav yuav qhov twg?

A: 75% ferrosilicon kim dua 72%, nyob ntawm kev ua lag luam, feem ntau yog ob peb puas yuan ntau dua ib tuj. Rau cov pa roj carbon zoo tib yam thiab castings, 72% txaus; rau alloy steel thiab export steel, 75% yog pom zoo.

Q: Kuv tau siv 75% ferrosilicon. Yog tias kuv hloov mus rau 72%, kuv puas yuav tsum tau hloov cov qauv?

A: Kev kho me ntsis yog xav tau. Cov ntsiab lus silicon ntawm 72% ferrosilicon yog 2-3 feem pua cov ntsiab lus qis dua 75%, yog li cov nyiaj ntxiv yuav tsum tau nce 5%-10%. Nws raug nquahu kom sim cov khoom me me ua ntej, sim cov ntsiab lus silicon ntawm cov khoom tiav, thiab tom qab ntawd kho kom zoo.

Q: Cov ntsiab lus ntawm silicon ntawm 72% ferrosilicon yog 72% -74%. Puas yog qhov kev hloov pauv loj dhau lawm?

A: Peb sim txhua batch ua ntej nws tawm hauv lub Hoobkas kom paub meej tias cov ntsiab lus silicon hloov pauv tau tswj tsis pub dhau ± 1%. Piv txwv li, yog tias koj xav tau 72%, cov khoom peb muab yuav nyob nruab nrab ntawm 71% -73%. Ib daim ntawv ntsuam xyuas yog suav nrog cov khoom.

Q: Kuv puas yuav tsum siv 72% lossis 75% ferrosilicon ua ib qho inoculant?

A: Ob leeg zoo. Lub ntsiab tseem ceeb rau inoculants yog qhov loj thiab cov ntsiab lus ntawm aluminium. Feem ntau, 1-3mm lossis 3-8mm hais yog siv, thiab cov ntsiab lus txhuas ntawm 1%-2% yog qhov zoo rau kev siv tshuaj. Raws li rau 72 lossis 75, qhov sib txawv yog tsawg.
