Calcium silicon lumps
Cov khoom lag luam
Calcium silicon (Casi) Lumps yog ib qho tseem ceeb heev hauv kev ua haujlwm me me, ua pov thawj cov khoom lag luam hlau, thiab txawm tias muaj hlau manloy. Cov lumps no, ua los ntawm kev sib xyaw ntawm cov calcium (ca) thiab silicon (si), xa tsis tau kev ua hauj lwm zoo hauv deoxidation, thiab cov txheej txheem inoculation.
Calcium silicon lumps yog ferrroalloloy muaj cai ntawm:
- 28-35% calcium (ca) - txhim kho cov deoxidation thiab desulfurization.
- 55-65% silicon (Si) - txhim kho folicity thiab tswj impurities.
- Me me ntawm cov hlau, txhuas, thiab cov carbon - nyob ntawm qib.
Cov qog no yog tsim nyob rau hauv hluav taws xob arc los ntawm carbothermic txo cov khoom nyoos zoo li txiv qaub, quartz, thiab coke. Qhov tshwm sim yog ib qho kev hloov siab heev, ua rau muaj txiaj ntsig uas tau hloov kho Molten hlau.
Cov ntawv thov tseem ceeb ntawm calcium silicia silic silic silic silicia lumps
1. Steelmaking: muaj zog dua, nqus tsev ntxhua khaub ncaws hlau 🔥
Deagidation - tshem tawm cov oxygen los ntawm Molten hlau, tiv thaiv porosity thiab tej yam tsis xws luag.
Desulfurization - txo cov lus faj sulfur, txhim kho steel nyuaj thiab weldability.
Cov kev hloov pauv hloov pauv - Hloov pauv cov roj oxides / sulfides rau hauv cov kab mob uas tsis sib haum.
2. Cia Hlau Ntau Lawm: Zoo Casting Zoo 🛠️
Inoculation - txhawb nqa graphite tsim, txhim kho tshuab luam ntawv thiab lub zog.
Nodularization - qhov tseem ceeb hauv cov hlau uas tseem ceeb hauv cov hlau ntau lawm rau kev lag luam thiab kev lag luam yeeb.
3. Tsis - ferrous alloys & Cov hlau tshwj xeeb �
Siv hauv cov hlau nplaum ntau dua li tus neeg sawv cev txo qis.
Pab ua kom ua kom ua kom paub cov alloys alloys los ntawm kev tshem tawm impurities.
4. Cored Hlau Txhaj Tshuaj 📈
Tsoo Casi tau ntim rau hauv cov xov hlau cored rau kev kho ntaiv zoo.
Saib xyuas kev tswj cov khoom siv tsawg heev.
Vim li cas thiaj xaiv cov qog hla cov hmoov lossis cov granules?
Thaum casi muaj nyob rau hauv hmoov, granules, thiab cored hlau cov ntaub ntawv, lumps kev xaiv ib qho kev xaiv rau ntau qhov kev lag luam vim tias:
Density ntau dua - tsis tshua muaj kev nplua me me thiab zoo dua tawm los.
✅ Txo cov hluav taws xob qis nrog huab cua - txo cov oxidation thaum lub sijhawm khaws cia.
✅ Yooj Yim Tshaj & Chaw Cia Khoom - Cov plua plav tsis muaj plua plav, kev nyab xeeb.
In {-}}} Ua tau zoo - qis dua kev poob peev txheej piv rau cov hmoov zoo.
Qauv Qauv & Qib Kawm Qib Zoo
Cov lag luam sib txawv yuav tsum muaj cov kev ua haujlwm cas. Cov qib kawm muaj xws li:
| Teem nqi | Calcium (ca)% | Silicon (si)% | Thawj siv |
|---|---|---|---|
| CASI 30 | 28-32% | 58-62% | Steelmaking, desulfurization |
| Casi 35 | 33-37% | 55-60% | High - Daim ntawv thov tshuaj calcium |
| Tsawg - ib tug casi | <1.5% Al | 60-65% SI | Hwm Hlau Qib |
Cov Qauv Kev Lag Luam:
ISO 5445 (Thoob Ntiaj Teb)
ASTM A495 (USA)
GB / T 3419 (Suav Teb)
Cov lus qhia yuav: Yuav ua li cas rau cov chaw zoo tshaj plaws calcium silicon lumps
Thaum kos duab casi lumps, xav txog:
Purity purity qib - Tsawg Aluminium & carbon rau high - qib steel.
🔹 Qhov loj me me - feem ntau 10-50mm rau kev ua siab zoo melting.
🔹 Cov Khoom Siv Hluav Taws Xob - Chaw Tsim Tshuaj Txhim Kho Kom Ntseeg tau zoo.
🔹 Ntim - noo noo - tsis kam, ntim hnab lossis ntim ntim.
Lub neej yav tom ntej ntawm calcium silicon hauv kev lag luam
Nrog Rising thov kom high - Performation Steel thiab Hnav Nyuaj Hlau, calcium silicon lit yuav nyob hauv:
- Ntsuab steel ntau lawm (qis - cov roj carbon steelmaking).
- Lub tsheb fais (EV) (ductiles hlau seem).
- Infrastructure tej yaam num (corrosion - tsis kam rebars).
