Se "mazino eindasitiri", simende carbide inoshandiswa zvakanyanya muindasitiri yemauto, aerospace, mechanic processing, metallurgy, kuchera mafuta, maturusi emigodhi, kutaurirana kwemagetsi, kuvaka uye mamwe minda. Nekuvandudzwa kwemaindasitiri epasi, kudiwa kwemusika wecemented carbide kuri kuramba kuchiwedzera. Mune ramangwana, kugadzirwa kwezvombo zvemhando yepamusoro-soro nemidziyo, kufambira mberi kwesainzi uye tekinoroji, uye kukurumidza kusimukira kwesimba renyukireya kuchawedzera zvakanyanya kudiwa kwezvigadzirwa zvecarbide zvine simende yemhando yepamusoro uye kugadzikana kwemhando yepamusoro. Cemented carbide inogonawo kushandiswa kugadzira maturusi ekuchera dombo, maturusi ekuchera, maturusi ekuyeresa, maturusi ekuyeresa, maturusi ekukuya, mabearings chaiwo, nozzles, hardware molds, nezvimwe.

Chii chinonzi simende carbide? Cemented carbide chinhu che alloy chakagadzirwa neakaomeswa makomisheni esimbi dzinoramba uye masimbi ekubatanidza kuburikidza nehupfu metallurgy. Icho chigadzirwa chehupfu chesimbi chakagadzirwa ne micron-saizi poda yeyakanyanya-kuoma refractory simbi carbides (tungsten carbide-WC, titanium carbide-TiC) sechikamu chikuru, cobalt (Co) kana nickel (Ni), molybdenum (Mo) se binder, yakasiirwa muvira revacuum kana muchoto wekudzikisa hydrogen. Iine nhevedzano yezvivakwa zvakanakisa senge kuomarara kwakanyanya, kupfeka kuramba, simba rakanaka uye kuomarara, kudzivirira kupisa, uye kusagadzikana kwekuora. Kunyanya, kuoma kwayo kwepamusoro uye kusapfeka kwekudzivirira kunoramba kusingachinjiki kunyangwe patembiricha ye500 ° C, uye ichiri nekuoma kwakanyanya pa1000 ° C. Panguva imwecheteyo, nekuvandudza tekinoroji yekupfekedza, kupfeka kuramba uye kuomarara kwesimende maturusi e-carbide akaita kusvetuka.

Tungsten chinhu chakakosha chesimende carbide mbishi zvinhu, uye inodarika 80% yetungsten inodiwa mukugadzira simende carbide. China ndiyo nyika ine zviwanikwa zvetungsten zvakapfuma pasi rose. Sekureva kweUSGS data, epasirese tungsten ore reserves muna 2019 angangoita 3.2 miriyoni matani, ayo eChina tungsten ore reserves aive 1.9 miriyoni matani, achiverengera angangoita 60%; kune akawanda edzimba tungsten carbide makambani ekugadzira, akadai se Xiamen Tungsten Indasitiri, China Tungsten High-tech, Jiangxi Tungsten Indasitiri, Guangdong Xianglu Tungsten Indasitiri, Ganzhou Zhangyuan Tungsten Indasitiri, etc. zvakakwana.

China ndiyo nyika ine kugadzirwa kukuru kwecemented carbide pasi rose. Zvinoenderana nenhamba kubva kuChina Tungsten Indasitiri Association, muhafu yekutanga ya2022, emunyika simende indasitiri yecarbide mabhizinesi akaburitsa huwandu hwe23,000 matani ecemented carbide, gore-pa-gore kuwedzera kwe0.2%; vakawana mari huru yebhizinesi ye18.753 bhiriyoni yuan, gore-pa-gore kuwedzera kwe17.52%; uye vakawana purofiti ye1.648 bhiriyoni yuan, gore-pa-gore kuwedzera kwe22.37%.

Nzvimbo dzinodiwa dzemusika wakasimwa carbide, senge mota nyowani dzesimba, ruzivo rwemagetsi uye kutaurirana, ngarava, hungwaru hwekugadzira, aerospace, CNC muchina maturusi, simba idzva, simbi molds, kuvaka zvivakwa, nezvimwewo, zvichiri kukura nekukurumidza. Kubva 2022, nekuda kwekukanganisa kwekuchinja kwemamiriro ekunze akadai sekuwedzera kwekupokana kwematunhu, nyika dzeEU, dunhu rakakosha rekugadzirwa kwe carbide yepasi rose uye kushandiswa, dzakaona kuwedzera kwakanyanya kwemitengo yemagetsi ekugadzira carbide uye mutengo wevashandi. nekuda kwekukwira kwemitengo yesimba. China ichave yakakosha mutakuri wekufambisa kweiyo simende indasitiri yecarbide.
