Dab tsi yog Sintered hlau qhov chaw:
Sintered hlau qhov chaw yog tsim los siv cov txheej txheem hmoov metallurgy hu ua sintering. Nyob rau hauv txoj kev no, hlau hmoov yog compressed rau hauv ib tug meej zoo, thiab ces tshav kub yog siv los txuas cov hlau hais nyob rau hauv cov khoom tsim, ua kom nws tswj nws cov duab tshiab. Sintering tuaj yeem siv los tsim ntau hom hlau thiab sib xws nrog ntau yam hlau thiab alloys.
JIEHUANG Sintered Metals yog cov kws tshaj lij hauv cov txheej txheem sintering uas hloov cov hmoov hlau rau hauv cov khoom siv hlau ruaj khov thiab ruaj khov. Kawm paub ntxiv txog cov txheej txheem hlau sintering thiab nws yuav pab tau koj li cas los ntawm kev nyeem ntawv.
Dab tsi yog qhov txheej txheem sintering:
Sintering txheej txheem yog npaj cov hlau ore hmoov, flux, roj thiab hloov raws li qhov yuav tsum tau ntawm moj tej tawg rauv smelting, raws li ib tug tej feem ntawm batching, sib tov, ntxiv dej lubrication. Regranulation, tis ignition, nrog kev pab los ntawm tus kiv cua, kom nyob rau hauv qhov kev txiav txim ntawm ib tug tej yam kub kub, nto ntawm ib co hlau ore hmoov softening thiab melting, tsim ib tug tej yam kua theem, thiab lwm yam kawg melting ore hais, tom qab txias, cov kua theem yuav lo cov ntxhia hmoov hmoov rau hauv blocks txheej txheem no yog sintering txheej txheem.
Basic sintering txheej txheem
hmoov nias → them (kev npaj ua ntej thauj khoom thiab sintering) → sintering (preheating, preheating thiab txias) → tawm → sintered lub cev
Dab tsi yog qhov zoo ntawm Sintered hlau qhov chaw
●Los ntawm sintering, zoo sinter nrog ruaj khov tshuaj muaj pes tsawg leeg, uniform particle loj, zoo reducibility thiab siab metallurgical kev ua tau zoo muaj peev xwm muab rau blast furnace, uas tsim cov kev mob zoo rau high quality, high yield, tsawg noj thiab lub neej ntev.
● Muaj peev xwm tshem tawm cov teeb meem impurities xws li sulfur, zinc, thiab lwm yam.;
●Industrial pov tseg, xws li blast furnace plua plav, dov steel, sulfuric acid slag, steel slag, thiab lwm yam.;
● Cov hlau tsis-ferrous thiab cov hlau tsis tshua muaj hauv ntiaj teb tuaj yeem rov qab tau.
Sintering kub ntau yam ntawm Sintered hlau

Dab tsi yog Common sinteredcov ntaub ntawv hlau:
Hard alloy: tsim los ntawm tungsten, cobalt, carbon thiab lwm yam hlau, nrog rau siab hardness, muaj zog hnav tsis kam, corrosion kuj thiab lwm yam khoom, dav siv nyob rau hauv machining, mining thiab lwm yam teb.
Tungsten alloy:Feem ntau yog tsim los ntawm tungsten, hlau, npib tsib xee thiab lwm yam hlau, nrog kev ceev ceev, siab zog, siab melting point thiab lwm yam ntxwv, feem ntau siv nyob rau hauv kev tsim khoom ntawm aerospace thiab lub teb chaws tiv thaiv qhov kub-kub.
Pob zeb diamond composite khoom: Pob zeb diamond raws li cov khoom siv tseem ceeb, los ntawm cov txheej txheem sintering thiab lwm cov ntaub ntawv hlau sib xyaw, muaj cov tawv tawv zoo heev, thermal conductivity, yog dav siv hauv kev sib tsoo, txiav, hluav taws xob, lub zog thiab lwm yam.
Nano Ceramic Composite Khoom: tsim los ntawm cov khoom siv hlau, oxides, thiab lwm yam, nrog lub zog siab, siab tawv, siab hnav tsis kam thiab kub kub stability, haum rau kev kub ceev txiav, kub sintering, hluav taws xob thiab lwm yam kev lag luam.
Tsis tas li ntawd, sintered hlau cov ntaub ntawv kuj muaj xws li ntau yam tshwj xeeb alloys, ceramic composite cov ntaub ntawv thiab nano hlau cov ntaub ntawv.
