Ma waena o ka ʻoki ʻana i nā mea hana, hoʻohana nui ʻia ka carbide cemented e like me ke ʻoki ʻana i nā mea hana, e like me ka hoʻohuli ʻana i ka mea hana, ka mea ʻoki milling, planer, drill bit, boring tool, etc. graphite, aniani, pōhaku a me ke kila maʻamau, a no ka ʻoki ʻana i nā mea refractory e like me ke kila wela, ke kila kila, ke kila manganese kiʻekiʻe a me ke kila mea hana.Hoʻomaopopo nui ʻia ka ʻoki ʻana e nā mea mīkini.I kēia manawa, ʻo ka nui o ka carbide cemented i hoʻohana ʻia i ka ʻoki ʻana i nā mea hana e pili ana i ka 1/3 o ka nui o ka hana ʻana o ka carbide cemented ma Kina, kahi o 78% i hoʻohana ʻia no nā mea hana welding a me 22% no nā mea hana indexable.
Hoʻohana nui ʻia nā mea hana ʻoki i ka hana ʻana.Hoʻohana nui ʻia nā mea hana ʻoki carbide cemented i ka ʻoki kiʻekiʻe ma muli o ko lākou mau waiwai maikaʻi (ikaika kiʻekiʻe, paʻakikī kiʻekiʻe, paʻakikī kiʻekiʻe, kūpaʻa wela maikaʻi a me ka paʻakikī wela).ʻO nā ʻoihana kuʻuna ma lalo e like me nā mīkini a me nā kaʻa, ka moku, ke kaʻaahi, ka lepo, ka lole, a pēlā aku;kiʻekiʻe kiʻekiʻe a me ka puka ʻana o ka noi ʻana e pili ana i ka aerospace, ʻoihana ʻike, a me nā mea ʻē aʻe.
ʻO ka mea mua, ʻo nā ʻōnaehana hoʻoponopono mechanical nā huahana koʻikoʻi o ke kaulahao ʻoihana cemented carbide, kahi e pili ana i ka hana ʻana i lalo a me ka hana ʻana i nā māla e like me nā mīkini mīkini CNC, aerospace, mechanical mold processing, shipbuilding, marine engineering equipment, etc. ʻO ka National Bureau of Statistics, ua hoʻi hou ka helu o ka ulu ʻana o ka ʻoihana nui a me nā mea hana kūikawā o Kina no ʻelua mau makahiki ma hope o ka hoʻohaʻahaʻa ʻana i ka makahiki 2015. , me ka piʻi ʻana o ka makahiki he 8.5%;ʻO ka waiwai hoʻopuka o ka ʻoihana hana ʻoihana kūikawā he 3.66 trillion yuan, me ka piʻi ʻana o ka makahiki he 10.20%.E like me ka hoʻopukapuka waiwai paʻa i ka ʻoihana hana i lalo a hoʻihoʻi hou, e piʻi hou ka noi no ka hoʻoponopono ʻana i ka ʻoihana mīkini.
Ma ka hana kaʻa, ʻo kekahi o nā mea paahana koʻikoʻi i ka ʻoihana ʻoihana kaʻa ʻo ia ka mea hoʻoheheʻe mea hana, a ʻo ka mea hana carbide cemented ka mea nui loa.Wahi a ka ʻikepili o ka National Bureau of statistics, ua hoʻonui ʻia ka nui o nā kaʻa o Kina mai 9.6154 miliona ma 2008 a i 29.942 miliona ma 2017, me ka awelika ulu o 12.03%.ʻOiai ke emi nei ka nui o ka ulu ʻana i nā makahiki ʻelua i hala iho nei, ma lalo o ke kumu o ke kumu kiʻekiʻe, e paʻa mau ke koi ʻana o nā mea ʻoki carbide cemented i ke kahua kaʻa.
ʻO ka ʻōlelo maʻamau, ma ke ʻano o ka ʻokiʻoki, paʻa ka ulu ʻana o ka ʻoihana kaʻa a me ka ʻoihana mīkini, a paʻa ke koi no ka carbide cemented.Ua manaʻo ʻia e ka 2018-2019, ʻo ka hoʻohana ʻana i nā mea ʻoki carbide cemented e hōʻea i 12500 tons a me 13900 tons i kēlā me kēia, me ka piʻi ʻana o ka ulu ʻana o nā helu ʻelua.
Geology a me ka mining: koi hou
Ma ke ʻano o nā mea hana geological a me ka mineral, hoʻohana nui ʻia ka carbide cemented e like me nā mea hana wili pōhaku, nā mea mining a me nā mea hana wili.Loaʻa i nā ʻano huahana ka bit drilling bit no ka wili percussive, drill bit for geological exploration, DTH Drill for mining and oilfield, cone drill, pick of coal cutter and impact drill for building materials.He kuleana koʻikoʻi nā mea hana eli carbide sima i ka lanahu, ka aila, nā mineral metala, ke kūkulu ʻana i nā ʻoihana a me nā mea ʻē aʻe.ʻO ka hoʻohana ʻana i ka carbide cemented i nā mea hana geological a me ka mining no ka 25% - 28% o ke kaumaha o ka carbide cemented.
I kēia manawa, aia nō ʻo Kina i ka waena waena o ka ʻenehana, a ke emi nei ka piʻi ʻana o ka ulu ʻana o ka pono kumu waiwai, akā e hoʻomau ka nui o ka noi.Ua manaʻo ʻia ma ka 2020, ʻo ka hoʻohana ʻana i ka ikehu mua o Kina e pili ana i 5 biliona tons o ka lanahu maʻamau, 750 miliona tons o ka hao hao, 13.5 miliona tons o ke keleawe i hoʻomaʻemaʻe ʻia a me 35 miliona tons o ka alumini kumu.
Ma lalo o ke kumu o ka hana koi kiʻekiʻe, ʻo ke ʻano o ka emi ʻana o ka pae mineral e hoʻoikaika hou i nā ʻoihana mining e hoʻonui i ka hoʻolimalima kālā.No ka laʻana, ua hāʻule ka awelika o ka ʻai gula mai 10.0 g / T i ka 1970s mua a hiki i kahi 1.4 g / T ma 2017. Pono kēia e hoʻonui i ka hoʻopuka ʻana o ka ʻaila maka e mālama ai i ka paʻa o ka hana metala, no laila ke koi nei i ka noi nā mea hana eli e ala aʻe.
I nā makahiki ʻelua e hiki mai ana, ʻoiai ke kiʻekiʻe nei nā kumukūʻai o ka lanahu, ka aila a me nā minela metala, ua manaʻo ʻia e piʻi mau ka makemake o ka ʻeli ʻana a me ka ʻimi ʻana, a e hoʻomau ka piʻi nui ʻana o ka noi no ka carbide cemented no nā mea hana geological a me ka mining.Manaʻo ʻia e mālama ʻia ka nui o ka ulu ʻana o ka noi ma kahi o 20% ma 2018-2019.
E hoʻohana i nā mea hana pale: hoʻokuʻu koi
Hoʻohana nui ʻia ka carbide i hoʻopaʻa ʻia i ka mīkini i loko o nā huahana mechanical structure o nā ʻano ʻano ʻaʻahu kūʻokoʻa, ʻo ia hoʻi nā molds, kiʻekiʻe-puʻe a me ke kiʻekiʻe wela o nā ʻāpana, nā ʻāpana kūʻokoʻa, a me nā mea ʻē aʻe. 8% o ka huina puka o ka cemented carbide, a me ka lua no ke kiʻekiʻe puʻe a me ke kiʻekiʻe wela kū'ē helu no ma kahi o 9% o ka huina puka o cemented carbide.ʻO nā ʻāpana pale ʻaʻahu e pili ana i ka nozzle, alakaʻi alakaʻi, plunger, pōpō, peni anti-skid pin, snow scraper plate, etc.
ʻO ka lawe ʻana i ka mold ma ke ʻano he laʻana, ma muli o nā ʻoihana e hoʻohana nui ana i nā mold, me nā kaʻa, nā mea hana hale, a me nā ʻoihana ʻē aʻe e pili kokoke ana i ke ola o nā kānaka i kēlā me kēia lā, ma lalo o ke ʻano o ka hoʻonui ʻana, ʻoi aku ka wikiwiki o ka hoʻonui ʻana i nā huahana. , a ʻoi aku ka kiʻekiʻe o nā koi no nā mold.Ua manaʻo ʻia ʻo ka nui o ka ulu ʻana o ka make cemented carbide koi ma 2017-2019 e pili ana i 9%.
Eia kekahi, ʻo ke koi ʻana no ka carbide cemented no nā puʻu kiʻekiʻe a me ka wela kiʻekiʻe a me nā ʻāpana mīkini paʻa e manaʻo ʻia e hoʻonui ʻia e 14.65% a me 14.79% i ka makahiki 2018-2019, a e piʻi ka noi i 11024 tons a me 12654 tons. .
