Production ndiApplication waSimenti Carbide Wophwanyidwa Grits

Njira yopangira carbide yophwanyidwa imaphatikizapo njira ziwiri: kuphwanya ndi kuwunika.

Choyamba, akuphwanya kaloti kungagawidwe m'njira ziwiri: kuphwanya pamanja ndi kuphwanya makina. 

1. Zinyalala zolimba zotayidwa zimatenthedwa kupitirira 800 ° C mu ng'anjo pogwiritsa ntchito njira yophwanyira pamanja, ndipo nthawi yomweyo zimayikidwa m'madzi kuti zizizizira, kotero kuti simenti ya carbide imasweka. Carbide yoswekayo imaphwanyidwa mkati mwa belu lachitsulo.

2. Njira yophwanyira makina amawotchi atha kugwiritsidwa ntchito ngati nyundo kapena chopondaponda. Ndi bwino kusankha zophwanya mpukutu ziwiri pa ntchitoyi, imodzi yothyola movutikira, ina yothyola bwino. Kuti musinthe mtunda pakati pa odzigudubuza awiri a mpukutuwo, mutha kuchita izi molimbika, tebulo limodzi kuti muphwanye movutikira, linalo kuti muphwanye bwino. Kuti musinthe mtunda pakati pa odzigudubuza awiri a mpukutuwo, mutha kuchita izi molimbika, tebulo limodzi kuti muphwanye movutikira, linalo kuti muphwanye bwino. Kuti musinthe phula pakati pa zodzigudubuza ziwiri za mpukutuwo, carbide ya simenti imatha kuthyoledwa m'magawo osiyanasiyana a tirigu.

Second, kusefa ndi kusanja.

Zogulitsa zazing'ono zothyoledwa ndi manja zimasefedwa ndi chophimba chokhazikika.Kuchuluka kwa zinthu zambiri zogwiritsira ntchito makina ogwedezeka chophimba.Ngati zenera logwedezeka la masanjidwe asanu lisankhidwa, mankhwalawa atha kuwonedwa m'magulu asanu a tinthu tating'ono nthawi imodzi. Mamilimita a coarse grained cemented carbide amatha kusinthidwa ndi chophimba chamanja chodzipangira chokha chachitsulo chosapanga dzimbiri.Chitsulo chosapanga dzimbiri chokhala ndi makulidwe a 2 mm chimawotcherera mu mbale yosaya, ndipo mabowo ena amabowoleredwa mu mbale yakuya molingana ndi gulu linalake la tinthu tating'onoting'ono kuti akhale chophimba cha millimeter.

Osiyana tinthu kukula osiyanasiyana granular simenti carbide, ntchito yake ndi yosiyana.Zotsatirazi ndinena za kagwiritsidwe kake ka granular carbide mumitundu yosiyanasiyana ya tinthu. Padzakhala zofunsira khumi zonse.

1. Zida zobowola m'mabwinja

Carbide composite kuwotcherera ndodo amapangidwa ndi wosweka carbide ndi tinthu kukula 3 ~ 5 mm ndi mkuwa kapena chitsulo m'munsi filler zitsulo, ndiyeno kuwotcherera ndodo pamwamba pa mlomo wa kubowola pang'ono ndi mpweya acetylene lawi kupanga geological pachimake kubowola.Mwanjira iyi, chobowoleracho chimatha kubowola mumiyala 5 ~ 6, ndikuwongolera magwiridwe antchito anthawi 2-3 kuposa pobowola ndi mano olimba a carbide, ndipo kumwa carbide ndi gawo limodzi mwa magawo khumi a General kubowola pang'ono. Kubowola kwamtundu wotere kokhala ndi kuwotcherera kwa carbide kumadziwotcherera.

2.Chabwino stabilizer

Ufa wa simenti wa carbide wothyoledwa ndi makina umasakanizidwa ndi kuchuluka koyenera ndikuyika mu chubu chachitsulo cha 08 kuti apange ndodo zowotcherera, ndipo ndodo yowotcherera ikuyang'ana pa bala la chitsime chamafuta, zomwe zimathandizira kwambiri moyo wautumiki wa stabilizer. Moyo wautumiki wa chitsime cha mafuta umachulukitsidwa ndi 2 ndi nthawi 10, motsatana. Moyo wautumiki wa stabilizer yomwe ili ndi carbide yophwanyidwa ndi simenti ndi nthawi imodzi kuposa ma elekitirodi a tungsten carbide, komanso nthawi 15 kuposa ya cobalt chromium tungsten electrode.

3. Zopangira thupi la diamondi kubowola

M'dziko lathu, zinthu zakuthupi zakubowola diamondi zakhala zikuponyedwa tungsten carbide. Kuyambira 1985, North China Petroleum Administration yakhala ikuponya tungsten carbide ngati zida zobowola diamondi m'dziko lathu. Pali zabwino zambiri zogwiritsira ntchito WC-Co particle alloy ngati mthunzi. Poyerekeza ndi kuponyedwa kwa tungsten carbide, carbide yophwanyidwa imakhala yolimba kwambiri pakuyika kwa diamondi, yophatikizana kwambiri ndi thupi lachitsulo, ndipo kubowola kumakhala kosalala komanso kokongola pambuyo pa makina.

4. Zida zopha nsomba ndi mphero

Ndodo yowotcherera imapangidwa ndi chitsulo chophwanyidwa ndi simenti ndi zotanuka nickel silver alloy filler zitsulo, kenako ndikufikira ku zitsime zamafuta ndi zida zophera ndi lawi la oxyacetylene, lomwe limagwira ntchito yayikulu kwambiri pakubowola mafuta.

5. Dip pamwamba pa blast ng'anjo belu

Belu la ng'anjo yophulika nthawi zonse limakhudzidwa ndi chitsulo chachitsulo, coke ndi miyala yamchere, ndipo kuvala kumakhala koopsa kwambiri. M'mbuyomu, ndodo zowotcherera zachitsulo za chromium zakhala zikugwiritsidwa ntchito pochepetsa kuvala kwa belu. Belu la ng'anjo lophulika lokhala ndi mainchesi a 5 metres ndi voliyumu ya 5000 cubic metres idayikidwa mkati ndikuyang'ana ndi simenti ya carbide. Moyo wautumiki wa belu la ng'anjo yophulika ndi njira iyi ndi 3 ~ 8 nthawi yayitali kuposa yomwe ili ndi ma elekitirodi achitsulo opangidwa ndi chromium.

6. Tsamba locheka lopanda mano

Tsamba la macheka ili lilibe ming'alu, ndipo mbali yake yodula imapangidwa ndi zitsulo zosawerengeka za carbide zomangidwira papepala lachitsulo. Tsamba la macheka ili ndi lakuthwa ndipo limatha kudula zida zovuta kwambiri, mogwira mtima komanso mwachuma.

7. Ponyani mutu wa nyundo ndi mpira wachitsulo

Carbide wophwanyidwa wa simenti amafalikira mu nkhungu yoponyera, chitsulo chosungunula amabayidwa ndipo carbide yophwanyidwa imaphatikizidwa pamodzi kuti ipangitse kukula kwamitundu yosiyanasiyana ya ziwalo zosavala. Zigawo zamtundu uwu - nthawi zambiri zimagwiritsa ntchito 20 ~ 30 kapena 40 ~ 60 mauna a granular simenti carbide, kuponyedwa ndi kuyika ndi zitsulo zotayidwa ndi bwino kugwiritsa ntchito chitsulo cha manganese.

8. Zopangidwa ndi zitsulo zokhala ndi simenti ya carbide

The wosweka WC-Co aloyi ufa ndi zitsulo ufa amasakanizidwa wofanana, mbamuikha ndi kuwotchedwa, ndiyeno kulowetsedwa ndi aloyi yamkuwa kuti apange zipangizo kompositi. Zovala zosagwira ntchito zopangidwa ndi nkhaniyi zimakhala ndi makina abwino komanso kukana kuvala.

9. Kuvala kwapamwamba kwambiri

Coarse crystal WC ufa ndi WC-CO granular alloy amasakanikirana molingana ndi 60:40, wokutidwa pa chitsulo chokhala ndi chitsulo, kenako amathiridwa ndi chitsulo chamkuwa, ndikumangidwa kuti chikhale chonyamula ndi kukana kwambiri.

10.Thermal kutsitsi kuwotcherera molimba gawo zina

Ukadaulo wowotcherera wamafuta opopera a ufa wodzigudubuza wa aloyi monga chitsulo, faifi tambala ndi cobalt ndi wokwera. Pamwambapa osiyanasiyana kudzikonda kusakaniza aloyi ufa, kuwonjezera kuchuluka kwa 150-320 mauna granular simenti carbide ufa, ndiyeno utsi kuwotcherera, chifukwa carbide particles omwazikana mu kutsitsi kuwotcherera wosanjikiza, kukana kuvala kwa kutsitsi kuwotcherera wosanjikiza ndi kuchuluka kwambiri. Mwachitsanzo, tsamba lotulutsa mpweya lopangidwa ndi chitsulo chapakati cha kaboni lingagwiritsidwe ntchito kwa miyezi inayi yokha, ndipo moyo wautumiki umachulukira mpaka miyezi 16 pambuyo pa jekeseni wa malasha ndi faifi wopangidwa ndi aloyi wokhazikika wokhala ndi ufa wa 50% wosweka simenti wa carbide. Chofufutira cha chosakaniza chachitsulo chochepa cha alloy, moyo woyambirira ndi miyezi iwiri yokha, ndipo moyo wautumiki umakulitsidwa mpaka miyezi 12 mutatha kuwotcherera ndi ufa pamwambapa.

Ngati mukufuna zinthu za tungsten carbide ndipo mukufuna zambiri ndi zambiri, mungatheLUMIKIZANANI NAFEpa foni kapena makalata kumanzere, kapenaTITUMIZENI MAIpansi pa thistsamba.
