Txheej txheem cej luam ntawm cov txheej txheem Flow
Lub tshuab ua cov ferrotitanium hmoov feem ntau muaj tsib theem tseem ceeb: kev kho cov khoom siv raw, kev npaj alloy, shaping, sintering, thiab kho deg. Txhua theem tswj cov yam ntxwv zoo, thiab cov kab ke yog tsim los hloov cov khoom siv raw ferroalloy rau hauv cov hmoov nplej tiav los yog hmoov- metallurgy qhov chaw nrog cov lus piav qhia, qhov loj me thiab cov khoom siv tshuab.
Raw khoom kho
Alloy npaj (smelting)
Shaping (nias lossis txhaj tshuaj molding)
Sintering (kev kho cua sov)
Kev kho deg (sib tsoo, polishing, plating)
Raw Material Treatment thiab Alloy Preparation
Nyob rau hauv thawj theem, siab - zoo ferrotitanium raw khoom raug xaiv thiab raug crushing, sieving thiab sib tov kom huv si thiab uniformity. Cov hmoov kho yog ces them rau hauv lub qhov cub melting ua ke nrog cov ntsiab lus alloying nyob rau hauv kev tswj qhov sib piv thiab smelted ntawm qhov kub thiab txias, kom cov khoom sib xyaw kom huv si los ua kua alloy. Cov qib ferrotitanium feem ntau txhais tau los ntawm cov ntsiab lus titanium - piv txwv li FeTi30 (Ti txog 25-35%), FeTi40 (Ti txog 35-45%) thiab FeTi70 (Ti txog 65-75%) - thiab cov nqi txiav txim siab. Tom qab solidification, cov hlau yog crushed thiab milled, thiab cov hmoov yog cais los ntawm sieve loj kom tau raws li cov neeg siv khoom qhov particle loj specification.
Shaping thiab Sintering
Nyob rau hauv lub shaping theem, cov molten alloy tuaj yeem cam khwb cia ncaj qha, los yog hmoov tuaj yeem tsim rau hauv cov khoom ntsuab los ntawm kev nias lossis txhaj tshuaj molding, nyob ntawm seb cov khoom kawg ntawm daim ntawv. Cov khoom zoo li no tau muab tso rau hauv qhov cua sov- kho qhov cub rau sintering. High -kub sintering zoo tag nrho cov alloy crystallization, nce ceev, zog thiab hardness; rau titanium-cov kabmob alloys, sintering feem ntau yog ua nyob rau hauv lub tshuab nqus tsev lossis inert cua ntawm qhov kub ntawm li 1,100-1,400 degree, nyob ntawm seb muaj pes tsawg leeg, los tiv thaiv oxidation ntau dhau.
Kev kho deg thiab ua tiav
Sintered ferrotitanium cov khoom yuav muaj qhov ntxhib los yog nto oxidation. Sib tsoo thiab polishing rov qab qhov tseeb qhov tseeb thiab qhov chaw tiav, thaum plating lossis lwm yam txheej txheem tuaj yeem txhim kho cov tsos thiab corrosion kuj. Rau cov khoom siv hmoov, qhov chaw txias xws li deoxidation thiab passivation pab tswj cov pa oxygen thiab kev ruaj ntseg cia, uas yog ib qho tseem ceeb rau kev siv qis qis.
Kev Tswjhwm Zoo thiab Cov Txheej Txheem Tseem Ceeb
| Parameter | Hom Kev Tswj Lub Hom Phiaj |
|---|---|
| Cov ntsiab lus titanium | Matched rau qib (piv txwv li FeTi30 / FeTi40 / FeTi70) |
| Particle loj faib | Tswj los ntawm sieving thiab huab cua kev faib tawm ib qho tshwj xeeb |
| Qib impurity | Tsis tshua muaj oxygen, nitrogen thiab cov khoom seem rau cov hlau tsis sib xws |
| Pom meej ceev thiab flowability | ruaj khov rau kev pub noj, noj tshuaj thiab nias ua haujlwm |
| Deg mob | Ntxuav, oxidation -dawb nto rau hmoov thiab sintered qhov chaw |
Vim tias ferrotitanium yog siv rau hauv cov ntawv thov xws li titanium alloy master alloys, vuam consumables thiab hmoov metallurgy qhov chaw, batch-rau-batch sib xws thiab cov ntaub ntawv tsom xam yog qhov tseem ceeb ntawm cov txheej txheem tswj.
Cov lus nug nquag
Q1: Dab tsi yog cov kauj ruam tseem ceeb ntawm ferrotitanium hmoov ua?
Cov kauj ruam tseem ceeb yog kev kho cov khoom siv raw, kev npaj alloy (smelting), shaping, sintering thiab kho deg.
Q2: Cov qib twg ntawm ferrotitanium muaj?
Cov qib sib piv yog txhais los ntawm cov ntsiab lus titanium, piv txwv li FeTi30, FeTi40 thiab FeTi70, nrog cov npe titanium ntawm kwv yees li 25-35%, 35-45% thiab 65-75% feem.
Q3: Vim li cas sintering nqa tawm hauv lub tshuab nqus tsev lossis inert cua?
Titanium yog heev reactive nrog oxygen ntawm qhov kub thiab txias; lub tshuab nqus tsev los yog inert cua tiv thaiv ntau oxidation thaum sintering.
Q4: Particle loj tswj tau li cas?
Tom qab crushing thiab milling, cov hmoov yog cais los ntawm sieving thiab huab cua kev faib tawm kom tau raws li qhov xav tau mesh ntau.
Q5: Cov kev kho deg twg yog siv rau cov khoom ferrotitanium?
Sib tsoo, polishing thiab plating yog siv los txhim kho qhov chaw tiav, qhov tseeb qhov tseeb thiab corrosion kuj.
Q6: Vim li cas kev tswj xyuas zoo tseem ceeb hauv ferrotitanium hmoov ntau lawm?
Vim hais tias cov khoom siv yog siv nyob rau hauv daim ntawv thov uas muaj pes tsawg leeg thiab sib xws ncaj qha cuam tshuam rau qhov kawg alloy kev ua tau zoo, cov ntaub ntawv batch tsom xam yuav tsum tau.
