Sintering txheej txheem rau molybdenum rods

Molybdenum pas nrig ua tiav sintering txheej txheem (hmoov hlau metallurgy hydrogen siab -kub sintering)

Tag nrho cov txheej txheem ntws Molybdenum hmoov batching thiab sib tov → Isostatic nias molding / Moulded molding → Raw khoom decontamination thiab lubricant tshem tawm → High -kub hydrogen sintering → Txias thiab tawm → Tiav lawm sintered molybdenum pas nrig

Sintered molybdenum rods ceev yog 9.5 - 10.1 g/cm³. Porosity defects (qhov txawv tshaj plaws):

Crystal ciam teb yog npog nrog ntau cov dot dub -zoo li / ntev strip- zoo li lub qhov, nrog interconnected cua pores, txheeb ze ntom ntom 92% - 98%, Crystal ciam teb yog them nrog me me interconnected cua pores.

Coarse equiaxed nplej, grain loj 45-60 μm, grain ciam yog ncaj thiab unoriented, tsis muaj fiber ntau streamlines;

Daim duab saum toj no yog qhov ntev polishing nto ntawm ntug thiab cov tub ntxhais ntawm sintered billet ntawm molybdenum pas nrig

Oxygen ntsiab lus: 40-60 ppm;

Kev ua tau zoo hauv paus chiv keeb: Qhov txiav los ntawm matrix, tsis zoo thermal thiab hluav taws xob conductivity, siab nqus degassing rau sintered blanks, siab brittleness, yooj yim nkag los ntawm molten nruab nrab, siab nqus degassing.

1. Nws tuaj yeem tsim tau ultra-loj- txoj kab uas hla thiab ultra- ntev molybdenum rods uas tsis tuaj yeem ua tiav los ntawm cov khoom siv forging thiab tsuas tuaj yeem sintered;

2. Cov txheej txheem luv luv, kev siv hluav taws xob tsawg dua forging, thiab cov nqi tsim khoom tsawg;

3. Cov cuab yeej siv tau yooj yim thiab nws tsim nyog rau loj - nplai qis - tus nqi ntxhib blanks.

Yog li, Tus nqi qis, nws tuaj yeem ua qhov loj me, tab sis nws muaj micro- pores sab hauv, tsis muaj zog, thiab tsis muaj zog. Nws tsuas yog tsim nyog rau lub teeb -load, sib quas ntus siab - kub, tsis muaj zog yaig, thiab luv luv - lub sij hawm siv scenarios. Nws tsis tuaj yeem siv rau lub sijhawm ntev -cov kabmob, iav lub ntsiab electrodes, lossis cov khoom ua tiav.

1. Sab hauv qhov tsis tuaj yeem raug tshem tawm tag nrho, ua rau muaj qhov ntom ntom ntom ntom ntom ntom;

2. Lub zog, toughness, thiab siab -kub creep kuj yog qhov qis dua rau cov forged molybdenum;

3. Micro- qhov pores yog qhov ua rau cua ntxiab, thiab cov roj tso tawm ntim loj hauv lub tshuab nqus tsev; molten iav thiab hlau ua kua yog yooj yim nkag tau mus rau lub pores, thiab lub electrode lifespan yog luv.

1.High-kub sintering furnaces, hydrogen furnaces, lub tshuab nqus tsev vacuum, yooj yim kev pab cuam xws li me me pins, partitions, base pads, coj tus tuav, yuav tsis raug rau siab heev thiab yuav siv sij hawm intermittently.

2. Lub molybdenum cua sov sawb txuas nrog tus pas ntsuas hluav taws xob, cov hlau lead yooj yim - tawm electrode, thiab qis - lub zog hluav taws xob hluav taws xob cov khoom siv hluav taws xob. Nws yog powered rau ib lub sij hawm luv luv, tsis muaj kev pheej hmoo ntawm molten kua yaig.

3. Cov ceramic thiab hard alloy sintering tooling blanks yog siv los tuav cov pas nrig thiab kev txhawb nqa, tsis tuaj yeem cuam tshuam nrog cov hlau / iav, thiab tsuas yog cov khoom siv raw khoom.

1.Tsuas yog siv rau auxiliary electrodes, me me sab electrodes, thiab luv luv-term test electrodes; tsis tuaj yeem siv los ua lub ntsiab electrode rau iav fiber ntau kos duab:

Cov pas nrig conductive rau cov iav me me melting kilns hauv chav kuaj;

2. Cov iav me me me me rauv, ib ntus electrodes rau qhov cub ntsuas;
qhov tsis zoo: Micro-porous iav permeation, nruam ntau lawm ua rau corrosion sai thiab luv lifespan. Rau kev tsim khoom loj, txhua tus siv forged molybdenum rods.

1.Small conductive cathode thiab anode rods rau lub ntiaj teb tsis tshua muaj electrolytic hlwb (rau cov uas tsis tshua muaj tam sim no thiab ntiav molten ntsev tej yam kev mob)

2. Yooj yim thauj khoom-cov kabmob rods rau sintering ntawm tungsten, molybdenum thiab nyuaj alloy preforms;

3. Internal positioning thiab limiting Cheebtsam ntawm cov hlau txo qhov cub.

1. Nplaim txau thiab plasma txau ntawm molybdenum raw khoom rods (tsis muaj kev txwv nruj rau qhov ceev hauv cov txheej txheem txau);

2. Tus thawj loj - txoj kab uas hla sintered molybdenum rods ua ntej forging thiab dov yog siv los ua raw khoom blanks rau lub forging Hoobkas. Tom qab ntawd, lawv yog forged ntawm qhov kub thiab txias rau hauv ntom molybdenum rods, molybdenum xov hlau, thiab molybdenum daim hlau.

1. Tej yam yooj yim rwb thaiv tsev txhawb cov kab thiab qhov chaw rods rau lub tshuab nqus tsev vacuum zoo tib yam; tsis haum rau ultra- lub tshuab nqus tsev siab hauv semiconductor thiab
2. Yooj yim molybdenum lead-nyob rau hauv lub hauv paus rau cov teeb me me thiab halogen teeb (rau qhov tsis tshua muaj tam sim no thiab lub teeb load).

1. Rau cov machining ntxhib blanks uas tsis muaj qhov yuav tsum tau muaj zog thiab toughness, tsuas yog ua ntxhib tig;

2. Tsawg- nrawm, qis- thauj khoom hnav- tiv taus bushings thiab pins (tsis raug cuam tshuam lossis hloov pauv); Tsis txhob ua nyias- cov phab ntsa, cov xov zoo, los yog cov shafts, vim tias lawv yuav ua rau tawg thiab tawg.

1. Forging cua sov rauv, ntsev da dej rauv, thiab sab hauv yooj yim kev txhawb nqa rods thiab txhawb tuav rau cov khoom siv;

2. Titanium thiab npib tsib xee-raws li kev kho cua sov ntawm cov cuab yeej cuab tam qhov chaw, haum rau luv luv - lub sij hawm siab - kub siv.
