Ua paʻa mau ka ʻai ʻana o Kina i ka tungsten ma kahi o 10,000 tons / makahiki.Wahi a nā hōʻike, ʻo ka hoʻohana ʻana i ka tungsten ma Kina he 9,200 tons, 9,400 tons a me 9,500 tons ma 1994-1996, a ʻo ka hoʻohana ʻana i ka tungsten ma Kina ua wānana ʻia he 11,500 tons i ka makahiki 2000. Ua loli mālie ʻo Kina.Hōʻike nā Statistics mai ka makahiki 1980 a hiki i ka makahiki 1985, ʻo ka hoʻohana ʻana o ka tungsten no ka hana ʻana i ke kila no 61% o ka nui o ka hoʻohana ʻana, e helu ana i ka hapa nui loa;Mai ka makahiki 1986 a hiki i ka makahiki 1990, ua emi ka hapa o ka tungsten i hoʻohana ʻia i ka hana kila i 48%, aʻo ka nui o ka tungsten i hoʻohana ʻia i ka carbide cemented i hoʻonui ʻia i 28%.Mai ka makahiki 1991 a hiki i ka makahiki 1995, e like me ka piʻi ʻana o ka carbide cemented, ʻoi aku ka nui o ka tungsten i hoʻohana ʻia i ka carbide cemented ma mua o ka tungsten i hoʻohana ʻia i ka hana kila, kokoke i 50% o ka nui o ka hoʻohana ʻana i ka tungsten home, aʻo ka hapa o ka tungsten i hoʻohana ʻia i ka hana kila i hāʻule i kahi kokoke. 40%.
ʻIke ʻia e pili pono ana ka hoʻololi ʻana o ka hoʻohana ʻana i ka tungsten ma Kina i ka hana ʻana o ka carbide cemented.No laila, he aha ke ʻano o ka hana ʻana o ka carbide cemented o Kina?ʻO ke ʻano o ka hana carbide i kēia manawa ma Kina.
ʻO Kinacarbide simaUa hoʻomaka ka ʻoihana i ka waena o 1950s, a ʻoiai ua hoʻokumu ʻia ka ʻōnaehana ʻoihana ma kahi o kanakolu mau makahiki ma mua o nā ʻāina i kūkulu ʻia o ka Hikina a me ke Komohana, ʻo ka wikiwiki o kona hoʻomohala ʻana a me ka nui o kāna hana ʻana he mea kupaianaha i ka honua.ʻOi loa i nā makahiki 1990, ma lalo o ka hoʻoponopono hou ʻana a me ka wehe ʻana a me ka hoʻokele waiwai o ka mākeke, ua piʻi kiʻekiʻe ka hopena o ka carbide cemented.I kēia manawa, aia he 150 mau mea hana carbide i hoʻopaʻa ʻia ma Kina, me ka nui o ka mana hana o 9,000-10,000 tons / makahiki.ʻO ka nui o ka hana makahiki ma kahi o 7000-7500 tons, e helu ana i ka 21% o ka honua holoʻokoʻa makahiki, ʻoi aku ia ma mua o ʻAmelika Hui Pū ʻIa, Suedena, CIS a me nā ʻāina ʻē aʻe me ka ʻōnaehana ʻoihana cemented carbide i ka hana mua a me ka honua mua. .I loko o ka 8th Five-Year Plan, ʻo ka awelika o ka hana ʻana o ka carbide cemented ma Kina he 6528 tons (ʻo ka hana kiʻekiʻe loa o ka makahiki he 7540 tons i 1994), a ʻo ka awelika o ka hoʻohana makahiki he 5894 tons (ʻo ka ʻai makahiki kiʻekiʻe he 6620 tons) .Wahi a ka wānana a ka poʻe akamai, i ka wā o ka hoʻolālā ʻeiwa ʻelima mau makahiki, e piʻi ka awelika makahiki o ka carbide cemented ma Kina e 6%, ʻo ia hoʻi, ʻo ka awelika o ka hana makahiki e hiki i 6976 tons.Hoʻohana kekahi poʻe akamai i ka hoʻohālikelike laina laina e hoʻopili ai i ka hana kila a me ka carbide cemented ma Kina i ka hoʻolālā ʻEiwa ʻElima Makahiki.Ua hana ʻia ka simulation matematika e helu i nā hōʻailona ʻelua o GDP.
ʻO ke kolu, ka hana hou ʻana a me ka hoʻohana ʻana i nā ʻōpala a me nā koenacarbidema ke ʻano he mea e hoʻonui ai i ka nele o nā kumuwaiwai kūlohelohe
Ua kaupalena ʻia nā kumuwaiwai kūlohelohe, a ʻo ke kani ʻana o ke kani ʻana o ka nalo ʻana i ka pono o nā kumuwaiwai tungsten i ko mākou mau pepeiao.I mua o kēia kūlana pilikia, ua hoʻokumu ka poʻe akamai i nā hana hoʻoponopono a me nā hana hoʻoponopono.I waena o lākou, ʻo ke ʻano o ka hana hou ʻana a me ka hoʻohana ʻana i ke koena o ka tungsten carbide ua hōʻike ʻia he papahana makua, kūpono a kūpono hoʻi.He ala maikaʻi ia e hōʻemi ai i ke kumukūʻai o ka hana carbide i ka wā o ka nui o ka tungsten maka maoli, a he ʻano koʻikoʻi e hoʻihoʻi i ka nele o nā kumuwaiwai i kēia manawa a me ka wā e hiki mai ana i ka wā e pau ai ka tungsten maka maoli.ʻO ke kiʻekiʻe o ka hoʻohana piha ʻana i nā kumuwaiwai recycled kekahi o nā hōʻailona koʻikoʻi o ka holomua ʻenehana a me ka hoʻomohala waiwai o kahi ʻāina a me kahi ʻoihana.ʻO ka ʻoiaʻiʻo, ua hoʻokomo mua nā ʻāina i kūkulu ʻia ma ka Hikina a me ke Komohana i ka hana hou ʻana a me ka hoʻohana ʻana i ke koena o ka ʻōpala i ka hana maʻamau.I kēia manawa, ʻo kā lākou hana hou ʻana a me ka hoʻohana ʻana i ke koena o ka carbide cemented i hōʻea i ka 30-40% o ka huina makahiki.ʻO ka hoʻohana ʻana o Kina i ka metala tungsten i kēlā me kēia makahiki ma kahi o 10,000 tons, inā hiki iā ia ke hōʻea i ka 40% o ka hana hou ʻana, ʻoi aku ka nui o kāna mau waiwai waiwai a me ka hoʻonui waiwai.E lawe i ka carbide cemented ma ke ʻano he laʻana, ʻo ka huina o ka carbide cemented ma Kina i ka makahiki 1994 he 7540 tons, e like me ka helu ʻana o 40% hoʻihoʻi, ʻaʻole hiki iā mākou ke hoʻihoʻi hou i kahi kokoke i 3000 tons o tungsten metala, akā kokoke i 240 tons o ka metala cobalt. .E like me ka helu ʻana o ka ʻai ʻana i 2 tons o ka tungsten concentrate no kēlā me kēia 1 ton o ka carbide cemented i hana ʻia, hiki ke hoʻemi ʻia ka hoʻohana ʻana o ka tungsten concentrate ma kahi o 6000 tons.He mea kanalua paha keia i ka hoopau ana i ka hemahema o na kumuwaiwai.ʻO ke kūlana kumu o ka hana hou ʻana a me ka hoʻohana ʻana i ka carbide scrap ma Kina i kēia manawaʻO ke koena carbide ʻōpala a mākou e ʻōlelo ai ma ʻaneʻi he ʻelua ʻāpana: ʻo kekahi nā huahana kūpono ʻole i ke kaʻina hana;ʻo ka mea ʻē aʻe nā mea hana carbide i hoʻohana ʻia (nā ʻili, nā poʻo brazing, nā mold, etc.).
Wahi a nā helu helu ʻole, ʻo ka huina ocarbide koenahana ʻia ma Kina ma kahi o 3500 tons i kēlā me kēia makahiki.Wahi a nā mea hana carbide ʻē aʻe, i waena o nā mea hana carbide ʻōpala i hoʻohana ʻia, ma ka ʻōlelo maʻamau, hiki ke hana hou ʻia ka 12-25% o nā mea hoʻokomo wiliwili ʻōpala;65-70% o ka ʻōpala carbide make (make kuʻi, make kaomi, make kiʻi, etc.) hiki ke hana hou ʻia;Hiki ke hana hou ʻia ka 95-97% o nā mea hoʻokomo paʻa mīkini ʻōpala.
Ua hoʻomaka ʻo Kina e hana hou a hoʻohana i ka scrap carbide i ka lohi.I ka makahiki 1983, he 300 tons wale no ka nui o ka hana hou ana, a he 8% o na mea i puka mai i kela makahiki;i ka makahiki 1985, ua hoʻonui ʻia i ʻoi aku ma mua o 400 tons, ʻo ia ka 10% o ka huahana i kēlā makahiki.no ka 10% o ka hana i kēlā makahiki.I ka makahiki kanaiwa, ua ulu nui ka hana hou.I kēia manawa, ʻoi aku ma mua o 150 mau mea hana carbide cemented ma ka ʻāina, ʻaʻole wale ma kahi o 60 mau hale liʻiliʻi a me nā mea liʻiliʻi i loaʻa i ka tungsten maka kumu kumu mai nā kumuwaiwai recycled, ʻo ia hoʻi, me ka nui o Zhuzhou Cemented Carbide Factory a me Zigong Cemented Carbide Limited Liability Company.
