Kushandiswa kwemumba kweChina kwe tungsten kwakaramba kwakagadzikana paanenge 10,000 matani / gore.Sekureva kwemishumo, kudyiwa kwe tungsten kuChina kwaive matani 9,200, 9,400 matani uye 9,500 matani muna 1994-1996, uye kudyiwa kwe tungsten muChina kunofungidzirwa kuve matani 11,500 muna 2000. Kubva kuma1980, chimiro chekushandiswa kwetungsten China yave kuchinja chinyararire.Nhamba dzinoratidza kuti kubva ku1980 kusvika ku1985, chimiro chekushandisa che tungsten chekugadzira simbi chakaverengera 61% yehuwandu hwekushandisa, kuverenga kune chikamu chikuru;?Kubva 1986 kusvika 1990, chikamu che tungsten chaishandiswa mukugadzira simbi chakadzikira kusvika 48%, ukuwo chikamu che tungsten chakashandiswa mu simende carbide chakawedzera kusvika pa 28%.Kubva 1991 kusvika 1995, apo kubuda kwecemented carbide kwakawedzera, chikamu che tungsten inoshandiswa mucemented carbide chakapfuura icho tungsten inoshandiswa mukugadzira simbi, ichisvika 50% yehuwandu hwekushandisa tungsten mudzimba, ukuwo chikamu chetungsten inoshandiswa mukugadzira simbi chakaderera kusvika paanenge. 40%.
Zviripachena kuti shanduko ye tungsten yekushandisa chimiro muChina yakanangana nekugadzirwa kwecemented carbide.Saka, ndechipi chimiro cheChina chekugadzirwa kwe carbide?Ikozvino maitiro ekugadzirwa kwe carbide muChina.
China'ssimende carbideindasitiri yakatanga pakati pemakore ekuma1950, uye kunyangwe hurongwa hwemaindasitiri hwakaumbwa makore angangosvika makumi matatu gare gare kupfuura munyika dzakasimukira dzeMabvazuva neMadokero, kukurumidza kwekukura kwayo uye kukura kwekugadzirwa kwayo kwaishamisa pasirese.Kunyanya muma1990, pasi pekugadzirisa uye kuvhura uye hupfumi hwakatarisana nemusika, kubuda kwecemented carbide kwave kukwira kumusoro.Parizvino, kune 150 cemented carbide vagadziri muChina, ine yakazara kugadzirwa kwe9,000-10,000 matani / gore.Kugadzirwa kwepagore kwese kwe7000-7500 matani, inoverengera 21% yepasi rose kugadzirwa kwegore, iyo inopfuura United States, Sweden, CIS nedzimwe nyika dzine yakawedzera simende carbide maindasitiri system mukugadzirwa kwekutanga uye yekutanga yenyika. .Munguva yechisere yeChirongwa cheMakore mashanu, avhareji yegore yekugadzirwa kwecemented carbide muChina yaive 6528 matani (yepamusoro kugadzirwa kwepagore yaive 7540 matani muna 1994), uye avhareji yekushandisa pagore yaive 5894 matani (yakanyanya kushandiswa pagore yaive 6620 matani) .Maererano nekufanotaura kwenyanzvi, munguva yeNinth Five-Year Plan nguva, avhareji yegore negore yekugadzirwa kwecemented carbide muChina ichawedzera ne6%, kureva, kugadzirwa kwegore negore kuchasvika 6976 matani.Dzimwe nyanzvi dzinoshandisa linear correlation equation kubatanidza simbi uye simende kugadzirwa kwecarbide muChina panguva yeNinth Five-Year Plan.Iyo masvomhu simulation yakaitwa kuti iverenge zviratidzo zviviri zveGDP.
Chechitatu, kudzokorodza uye kushandiswa kwemarara uye zvakasaracarbidesenzira yekuwedzera kushomeka kwezvinhu zvakasikwa
Zviwanikwa zvechisikigo zvakaganhurirwa, uye alarm bhero yekurasikirwa nemukana we tungsten zviwanikwa zvave kuita maungira munzeve dzedu.Mukutarisana nemamiriro ezvinhu ane ngozi aya, nyanzvi dzakagadzira matanho akawanda ekugadzirisa uye kugadzirisa matanho.Pakati pavo, nzira yekudzokorodza uye kushandisa zvimedu zvakasara tungsten carbide yakaratidza kuva chirongwa chevakuru, chinoshanda uye chinoshanda.Iyo inzira inoshanda yekudzikisa mutengo wekugadzirwa kwecarbide panguva yekuwanda kwakaringana tungsten, uye chinhu chakakosha kugadzirisa kushaikwa kwezviwanikwa mune yazvino uye mune ramangwana apo tungsten yemusikirwo yave kupera.Dhigirii rekushandiswa kwakazara kwezviwanikwa zvakadzokororwa chimwe chezviratidzo zvakakosha zvekufambira mberi kwetekinoroji uye kusimukira kwehupfumi hwenyika uye bhizinesi.Muchokwadi, nyika dzakasimukira dziri kuMabvazuva neMadokero dzakatosanganisira kudzokorodza uye kushandiswa kwemarara akasara alloy mukugadzirwa kwakajairwa.Parizvino, kudzokorodza kwavo uye kushandiswa kwezvakasara zvakasimwa carbide kwasvika 30-40% yehuwandu hwegore rose kugadzirwa.Kushandiswa kweChina kwepagore kwe tungsten simbi kunosvika zviuru gumi zvematani, kana ichikwanisa kusvika makumi mana muzana ekudzokorodza, mabhenefiti ayo ehupfumi uye zviwanikwa zvekugadzirisa zviwanikwa zvichave zvakanyanya.Tora simende carbide semuenzaniso, iyo yakazara samende carbide muChina muna 1994 yaive 7540 matani, maererano nekuverenga kwe40% kupora, kwete chete isu tinogona kudzoreredza angangoita 3000 matani etungsten simbi, asiwo angangoita 240 matani ecobalt simbi. .Zvinoenderana nekuverenga kwekudya matani maviri etungsten concentrate ye1 toni yega yega simende carbide inogadzirwa, kushandiswa kwetungsten concentrate kunogona kudzikiswa neanoda kusvika 6000 matani.Izvi pasina mubvunzo zvichaita basa guru mukuderedza kushomeka kwezvekushandisa.Mamiriro ezvinhu ekutanga ekudzokorodza uye kushandiswa kwezvimedu carbide muChina parizvinoThe scrap carbide residue yatinoreva pano inosanganisira zvikamu zviviri: imwe ndiyo isina kukodzera zvigadzirwa mukugadzirwa kwekugadzira;imwe yacho ndiyo yakashandiswa scrap carbide tools (blades, brazing heads, molds, etc.).
Maererano nehuwandu husina kukwana, huwandu hwehuwandu hwezvakasara carbideinogadzirwa muChina inosvika matani 3500 pagore.Zvinoenderana nevagadziri vecarbide vekunze, pakati pezvishandiso zvecarbide zvakashandiswa, kazhinji kutaura, 12-25% yezvimedu zvekuisa welding zvinogona kushandiswazve;65-70% yezvakarasika carbide inofa (kurovera kunofa, kudzvanya kunofa, kudhirowa kunofa, nezvimwewo) kunogona kushandiswazve;95-97% yezvakarasa muchina clamping inoisa inogona kudzokororwa.
China yakatanga kudzokorodza uye kushandisa zvimedu carbide kunonoka.Muna 1983, vhoriyamu yekudzokorodza yaingova matani mazana matatu, achiverengera 8% yezvakabuda mugore iroro;muna 1985, yakawedzera kusvika pamatani anopfuura 400, zvichitora 10% yezvakabuda mugore iroro.yakaverengera 10% yezvakagadzirwa mugore iroro.Mumakore ekumapfumbamwe, basa rokudzorerazve rakava nebudiriro huru.Ikozvino kune vanopfuura zana nemakumi mashanu vanogadzira carbide munyika, kwete chete mafekitori madiki uye epakati nepakati ane tungsten ane tungsten zviwanikwa kubva kune zvakadzokororwa zviwanikwa, kureva, nechiyero cheZhuzhou Cemented Carbide Factory neZigong Cemented Carbide Limited Liability Company. (yaimbova Zigong Cemented Carbide Factory) yakavhurawo mutsara wekugadzira wetsvina yakadzokororwa yasara simende carbide.Parizvino, vhoriyamu yenyika yekudzokorodza iri pamusoro pe1500 matani, iyo inoverengera inosvika makumi maviri muzana kana kupfuura yezvese kubuda kwecemented carbide muChina uye iri pedyo nedanho reJapan.Iyo tekinoroji tekinoroji yekudzokorodza zvisaririra zvakasara cemented carbide yakwana,?s process ye zinc yekunyungudutsa nzira, magetsi ekunyungudika nzira uye mechanical kupwanya nzira inonyatso hunyanzvi.Iyo yakadzokororwa yakadzokororwazve tungsten carbide poda (WC) uye cobalt hupfu (Co), iyo yemhando yepamusoro, inogona kushandiswa kugadzira carbide, dhaimondi rekugadzira, simbi maindasitiri uye zvimwe zvigadzirwa.Kune matunhu akati wandei uko basa rekudzokorodza uye kudzorerazve rinonyanya kushanda, pakati paro pane: Zhuzhou neChangsha muHunan;Zigong in Sichuan;Qinghe muRuwa rweHebei;Jinan mudunhu reShandong;Mudanjiang mudunhu reHeilongjiang, nezvimwewo Vagadziri vecarbide munzvimbo idzi vakawana budiriro mukudzoreredza nekushandisa zvimedu zvakasara zvine simende carbide.
