Dab tsi yog Sintered hlau qhov chaw:
Sintered hlau qhov chaw yog ua los ntawm ib tughmoov metallurgy txheej txheem 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.Sinteringtuaj yeem siv los tsim ntau hom hlau feem ntau thiab yog sib xws nrog ntau yam hlau thiab alloys.
JIEHUANGSintered 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, ignition 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 hais rau hauv blocks txheej txheem no 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
