Kahua lawelawe piha no ka ʻoihana Metallurgical BURDEN o Kina

Ma hope o ke kaʻina mua o ka haʻalulu, ʻo ke ʻano o kēia manawa o ka mākeke electrode graphite ka hana paʻa. Wahi a ke anamanaʻo o ka paepae pale kumu kila φ Ke lawe nei i ka 450 ultra-high power graphite electrode ma ke ʻano he laʻana, ʻo ka ʻōlelo nui o ka hale hana me ka ʻauhau he paʻa ma waena o 19500-20500 yuan / ton.

I kēia manawa, ua hoʻopili ʻia nā mea maikaʻi a me nā mea maikaʻi ʻole i ka mākeke electrode graphite, kahi e pāʻani ai i kahi kuleana nānā a kaulike ma ka mākeke holoʻokoʻa. ʻO ka mea mua, ua piʻi ke kumukūʻai o ka coke petroleum sulfur haʻahaʻa ma ka hopena o nā mea maka, a ua kiʻekiʻe ke kumukūʻai o ka coke nila a me ka pitch tar lanahu. Eia kekahi, ua piʻi ke kumukūʻai hana graphitization i kēia manawa, a ua piʻi pū ke kumukūʻai hana o ka electrode graphite. Ua haʻahaʻa ka hana waihona ma ka pūnaewele, akā ʻaʻole maikaʻi loa ke kaomi waihona holoʻokoʻa. Maikaʻi maoli ka ʻaoʻao kumukūʻai.

Ma ke ʻano o nā ʻoihana kila ma hope, ʻaʻole haʻahaʻa ka nui o ka hana o nā hale hana kila umu uila, aia nō ke koi paʻa no nā electrodes graphite, aia nō kekahi mau hale hana kila i ka waihona, ʻaʻole kiʻekiʻe ka hoihoi no ke kūʻai ʻana i ka wā pōkole, a aia kahi ʻano hoʻemi kumukūʻai. Me ka hoʻokō ʻana i ke kulekele hoʻemi kila maka, hiki ke hoʻemi ʻia ke koi no ka electrode graphite, a ʻike ʻia nā mea maikaʻi ʻole.

Ma keʻano holoʻokoʻa, maikaʻi ke kālepa ʻana o ka mākeke electrode graphite, a pono e hoʻomau i ka hahai ʻana i ka hopena. ʻOiai aia kahi hoʻonui mai ka ʻaoʻao kumukūʻai, hāʻawi nā mea maikaʻi a me nā mea maikaʻi ʻole i ka manawa like, a hiki i ka mākeke electrode graphite ke hoʻomau i ka hana maʻalahi i ka wā pōkole.

Hoʻolauna i ka paepae pale kumu kila:

Kahua lawelawe piha no ka ʻoihana Metallurgical BURDEN o Kina

Ua hoʻokumu ʻia ka pūnaewele China Metallurgical BURDEN i ka makahiki 2009 a ua hoʻonui ʻia i kahi kahua pale kumu kila i ka makahiki 2019. Uhi ka lawelawe kahua i nā mea kōkua metallurgical, carbon, ferroalloy, kila, hoʻolei a me nā ʻoihana ʻē aʻe, a hāʻawi i nā mea hoʻohana me kahi kahua lawelawe piha no ka ʻoihana ukana metallurgical e hoʻohui ana i ka lawelawe ʻikepili, ka lawelawe kūʻai aku, ka lawelawe hana a me ka lawelawe loea.

Aia nā mea hoʻohana paepae ma nā ʻoihana uka, waena a me lalo, nā ʻoihana noiʻi ʻepekema a me nā hui o ke kaulahao ʻoihana, a komo piha nā lawelawe i loko o kēlā me kēia loulou o ka ʻoihana, e like me ke kūʻai ʻana i nā mea maka, ke kūʻai aku ʻana i nā huahana, ke kūʻai aku ʻana i nā hōʻailona, ​​​​ka hoʻokele hana, ka noiʻi ʻenehana a me ka hoʻomohala ʻana, ka logistics a me ka halihali. Ua lilo ka paepae i kahua media ʻoihana makemake nui ʻia no nā ʻoihana hoʻouka a me nā ʻoihana hoʻolei hao a me ke kila no ke kūkākūkā ʻikepili ʻoihana, ka hoʻolaha ʻana i ka hōʻailona ʻoihana, nā hana lako a me ke koi pūnaewele a me ke kūkulu ʻana i ka ʻike ʻoihana.

Lawe ka lawelawe hana uila ʻo Gangyuanbao i ka hoʻoponopono hou ʻana i nā lula hana, ke kūkulu ʻana i ka ʻōnaehana kūpaʻa a me ke kūkulu ʻana i ka ʻōnaehana hoʻokele naʻauao ma ke ʻano he manaʻo hana koʻikoʻi, a hilinaʻi i nā lawelawe kālā kaulahao hoʻolako pūnaewele me ke kaulike, ka bila a me ke kālā ma ke ʻano he koʻikoʻi, i mea e hoʻokō ai i nā hana pūnaewele ma nā loulou ʻekolu o nā ʻano ʻoihana ʻehā, e like me nā minelala, nā mea maka o ka umu, ka umu metallurgical a me ka hao a me ke kila metallurgy.
