Pakati pematurusi ekucheka, simende carbide inonyanya kushandiswa sekucheka maturusi emidziyo, senge kushandura chishandiso, milling cutter, planer, drill bit, boring tool, etc. inoshandiswa kucheka simbi yakakandwa, isiri-ferrous simbi, mapurasitiki, kemikari fiber. graphite, girazi, dombo uye simbi yakajairika, uye zvakare yekucheka zvinhu zvinoramba zvakadai sesimbi isingadziviriri, simbi isina tsvina, yakakwirira manganese simbi uye chishandiso simbi.Kucheka kunonyanya kuzivikanwa nematurusi emuchina.Parizvino, huwandu hwesimende carbide inoshandiswa mukucheka maturusi account inosvika 1/3 yezvese kugadzirwa kwecemented carbide muChina, iyo 78% inoshandiswa pakugadzira maturusi uye 22% inoshandiswa kune indexable maturusi.
Zvishandiso zvekucheka zvinonyanya kushandiswa mukugadzira.Cemented carbide yekucheka maturusi anoshandiswa zvakanyanya mukucheka-kumhanya nekuda kweakanakisa zvivakwa (kusimba kwepamusoro, kuomarara kwepamusoro, kuomarara kwepamusoro, kugadzikana kwakanaka kwekupisa uye kuomarara kwekupisa).Maindasitiri echinyakare epasi akadai semichina nemotokari, ngarava, njanji, mold, machira, nezvimwe;kuguma kwepamusoro uye minda yekushandiswa kwechikumbiro inosanganisira aerospace, indasitiri yemashoko, etc. Pakati pavo, michina uye kugadzirwa kwemotokari ndiyo inonyanya kukosha minda yekushandiswa kwecemented carbide zvishandiso mukucheka simbi.
Chekutanga, michina yekugadzirisa mhinduro ndiyo yakakosha zvigadzirwa zvecemented carbide industry chain, iyo yakanangidzirwa kuzasi kwekugadzira uye kugadzirisa minda senge CNC muchina maturusi, aerospace, mechanical mold processing, shipbuilding, marine engineering equipment, etc. Zvinoenderana nedata. yeNational Bureau of Statistics, kukura kwegore negore kweindasitiri yekugadzira michina yeChina yakawedzera zvakare kwemakore maviri akatevedzana mushure mekubuda muna 2015. Muna 2017, kukosha kwekubuda kweindasitiri yekugadzira michina yaive 4.7 trillion yuan. , nekuwedzera kwegore negore kwe8,5%;kukosha kwekubuda kweindasitiri yekugadzira michina yakakosha yaive 3.66 trillion yuan, nekuwedzera kwegore-pagore kwe10.20%.Sezvo yakasimwa mari yekudyara muindasitiri yekugadzira yakadzikira kunze uye yawedzera, kudiwa kwekugadzirisa zvigadziriso muindasitiri yemuchina kuchawedzera zvakare.
Mukugadzira mota, chimwe chezvishandiso zvakakosha muindasitiri yekugadzira mota chiumbwa chemidziyo, uye simende yecarbide chishandiso mold ndicho chikamu chayo chakakosha.Zvinoenderana nedata reNational Bureau of statistics, kugadzirwa kwemotokari kweChina kwakawedzera kubva pa9.6154 miriyoni muna 2008 kusvika 29.942 miriyoni muna 2017, neavhareji yekukura kwe12.03%.Kunyangwe kukura kuri kuita kudzikira mumakore maviri achangopfuura, pasi pemashure epamusoro, kudiwa kwekushandisa kwematurusi esimende ekucheka carbide mumunda wemotokari kucharamba kwakagadzikana.
Kazhinji kutaura, mumunda wekucheka, kukura kwechinyakare mota neindasitiri yemuchina yakagadzikana, uye kudiwa kwecemented carbide kwakagadzikana.Zvinofungidzirwa kuti panosvika 2018-2019, kushandiswa kwesemende yekucheka maturusi kuchasvika 12500 matani uye 13900 matani zvichiteerana, nekukura kweanopfuura manhamba maviri.
Geology uye migodhi: inoda kupora
Panyaya yezvishandiso zve geological uye zvicherwa, simende carbide inonyanya kushandiswa sematurusi ekuchera matombo, maturusi emigodhi uye maturusi ekuchera.Mafomu echigadzirwa anosanganisira kudhirowa kwematombo ekudhirowa kwepercussive, drill bit for geological exploration, DTH Drill yemugodhi neoiri, cone drill, pick yemarasha cutter uye kukanganisa kudhirowa kweindasitiri yezvivakwa zvekuvaka.Cemented carbide migodhi maturusi anoita basa rakakosha mumarasha, peturu, zvicherwa zvesimbi, kuvaka zvivakwa uye zvimwe zvinhu.Kushandiswa kwecemented carbide mu geological and migodhi maturusi anoita 25% - 28% yehuremu hwecemented carbide.
Parizvino, China ichiri pakati pechikamu cheindasitiri, uye chiyero chekukura kwesimba rekushandisa simba chiri kuderera, asi iyo yakazara inodiwa icharamba yakakwira.Zvinofungidzirwa kuti panosvika 2020, kushandiswa kwesimba kwekutanga kweChina kuchave kunosvika mabhiriyoni mashanu ematani emarasha akajairwa, 750 miriyoni matani esimbi, 13.5 miriyoni matani emhangura yakacheneswa uye 35 miriyoni matani ealuminium yepakutanga.
Pasi pemamiriro ekushanda kuri kudiwa zvakanyanya, kudzikira kwegiredhi rezvicherwa kunowedzera kumanikidza mabhizinesi emigodhi kuwedzera mari yekushandisa.Semuenzaniso, avhareji yegiredhi yegoridhe ore yakadonha kubva pa10.0 g / T mukutanga 1970s kusvika pa1.4 g / T muna 2017. Izvi zvinoda kuwedzera kubuda kwesimbi yakasvibirira kuchengetedza kugadzikana kwekugadzirwa kwesimbi, nekudaro kufambisa kudiwa kwe zvishandiso zvemigodhi kusimuka.
Mumakore maviri anotevera, sezvo mitengo yemarasha, mafuta uye zvicherwa zvesimbi zvichiramba zvakakwirira, zvinotarisirwa kuti migodhi uye chido chekuongorora chicharamba chichikwira, uye kudiwa kwekasimende ye carbide ye geological and mining tools icharamba ichiwedzera zvakanyanya.Zvinotarisirwa kuti huwandu hwekukura kwekuda huchachengetwa hunosvika makumi maviri muzana muna 2018-2019.
Pfeka midziyo isingachinji: inodiwa kusunungurwa
Kupfeka cemented cemented carbide inonyanya kushandiswa muzvigadzirwa zvemakina emhando dzakasiyana-siyana dzisingapfeki minda, kusanganisira molds, high-pressure uye high-temperature mhango, hembe dzisingapfeke, nezvimwewo. Parizvino, iyo simende carbide inoshandiswa kune akasiyana molds accounts kune anenge. 8% yekubuda kwesemented carbide, uye mhango yekumanikidza kwakanyanya uye yakanyanya tembiricha kuramba inoverengera inosvika 9% yeiyo yakazara inobuda simende carbide.Zvikamu zvinodzivirira kupfeka zvinosanganisira nozzle, njanji yekutungamira, plunger, bhora, tire anti-skid pin, snow scraper plate, nezvimwe.
Tichitora mold semuenzaniso, nekuda kwemaindasitiri anoshandisa mold zvakanyanya zvakanyanya, kusanganisira mota, midziyo yemumba, iyo uye mamwe maindasitiri evatengi ane hukama nehupenyu hwezuva nezuva hwevanhu, pasi pemamiriro ekusimudzira kwekushandisa, kugadziridzwa kwezvigadzirwa kunokurumidza uye nekukurumidza. , uye zvinodikanwa zvezviumbwa zvakare zvakakwirira uye zvakakwirira.Inofungidzirwa kuti iyo composite yekukura mwero we die cemented carbide kudiwa muna 2017-2019 ichave ingangoita 9%.
Pamusoro pezvo, kudiwa kwecemented carbide kune yakakwirira-kudzvanywa uye yakakwirira-tembiricha inodzivirira cavities uye kupfeka-inodzivirira mechanicha zvikamu zvinotarisirwa kuwedzera ne14.65% uye 14.79% zvakateerana muna 2018-2019, uye kudiwa kuchasvika 11024 matani uye 12654 matani. .
