Imakethi ye-graphite electrode, eyehla kunyaka ophelileyo, yenze utshintsho olukhulu kulo nyaka.
“Kwisiqingatha sokuqala sonyaka, iielectrode zethu zegraphite zazinqongophele.”Njengoko i-gap yemarike kulo nyaka imalunga neetoni ze-100,000, kulindeleke ukuba obu budlelwane obuqinileyo phakathi kokubonelela kunye nemfuno iya kuqhubeka.
Kuyaqondwa ukuba ukususela ngoJanuwari walo nyaka, ixabiso le-graphite electrode liye lanyuka ngokuqhubekayo, ukusuka malunga ne-18,000 yuan / toni ekuqaleni konyaka ukuya malunga ne-64,000 yuan / toni okwangoku, kunye nokunyuka kwe-256%.Kwangaxeshanye, inaliti ye-coke, njengeyona nto ibalulekileyo ye-electrode yegraphite, iye yanqongophala, kwaye ixabiso layo liye lanyuka ngayo yonke indlela, elinyuke ngaphezu kwama-300% xa kuthelekiswa nokuqala konyaka.
Imfuno yamashishini entsimbi esezantsi yomelele
I-electrode yegraphite yenziwe ikakhulu ngepetroleum coke kunye nenaliti yecoke njengezinto ezikrwada kunye netha yetha yamalahle njengesibophelelo, kwaye isetyenziswa ikakhulu kwi-arc steelmaking eziko, iziko elintywilayo le-arc, iziko lokumelana, njl njl. I-80% yokusetyenziswa ngokupheleleyo kwe-electrode yegraphite.
Ngo-2016, ngenxa yokuhla kwe-EAF steelmaking, ukusebenza kakuhle kwamashishini ekhabhoni kwehla.Ngokwezibalo, umthamo wentengiso we-graphite electrode e-China yehle nge-4.59% unyaka nonyaka ngowama-2016, kwaye ilahleko iyonke yamashishini aphezulu egraphite electrode ibe yi-222 yezigidi zeeyuan.Ishishini ngalinye lekhabhoni lilwa imfazwe yexabiso ukugcina isabelo salo semarike, kwaye ixabiso lokuthengisa le-graphite electrode liphantsi kakhulu kuneendleko.
Le meko iye yatshintshwa kulo nyaka.Ngokunzulu kohlaziyo lwecala lokubonelela, ishishini lentsimbi kunye nentsimbi liyaqhubeka nokuthatha, kwaye "intsimbi yentsimbi" kunye neziko eliphakathi zicocwe kwaye zalungiswa kwiindawo ezahlukeneyo, imfuno yeziko lombane kumashishini entsimbi iye yanda. ngokukhawuleza, ngaloo ndlela ukuqhuba imfuno yee-electrode zegraphite, kunye nemfuno eqikelelwayo yonyaka yeetoni ezingama-600,000.
Okwangoku, kukho amashishini angaphezu kwama-40 anomthamo wokuvelisa i-electrode yegraphite engaphezu kweetoni ezili-10,000 eTshayina, anomthamo wemveliso omalunga ne-1.1 yezigidi zeetoni.Nangona kunjalo, ngenxa yempembelelo yabahloli bokukhuselwa kwendalo kulo nyaka, amashishini okuvelisa i-electrode yegraphite kwiphondo laseHebei, eShandong naseHenan akwimeko yokuvelisa okulinganiselweyo kunye nokunqunyanyiswa kwemveliso, kwaye ukuveliswa kwe-graphite electrode ngonyaka kuqikelelwa malunga neetoni ezingama-500,000.
Umsantsa wemarike omalunga neetoni ezili-100,000 awunakusonjululwa ngamashishini anyusa umthamo wemveliso.UNing Qingcai uthe umjikelezo wemveliso yeemveliso ze-graphite electrode ngokuqhelekileyo ungaphezu kweenyanga ezimbini okanye ezintathu, kwaye kunye nomjikelo we-stocking, kunzima ukunyusa umthamo kwixesha elifutshane.
Amashishini eCarbon aye anciphisa imveliso kwaye avala, kodwa imfuno yamashishini ensimbi iyanda, nto leyo ekhokelela ekubeni i-electrode yegraphite ibe yintengiso eqinile kwimarike, kwaye ixabiso layo liye lanyuka yonke indlela.Okwangoku, ixabiso lemarike linyuke ngamaxesha e-2.5 xa kuthelekiswa noJanuwari walo nyaka.Amanye amashishini entsimbi kufuneka ahlawule kwangaphambili ukuze afumane iimpahla.
Ngokutsho kwabangaphakathi kwishishini, xa kuthelekiswa ne-blast furnace, intsimbi yesithando sombane igcina amandla ngakumbi, ihambelana nokusingqongileyo kunye nekhabhoni ephantsi.Nge-China ingena kumjikelo wokuhla kwe-scrap, intsimbi yesithando sombane iya kufezekisa uphuhliso olukhulu.Kuqikelelwa ukuba inxalenye yayo kwimveliso yentsimbi iyonke kulindeleke ukuba inyuke ukusuka kwi-6% ngo-2016 ukuya kwi-30% ngo-2030, kwaye imfuno ye-graphite electrode isenkulu kwixesha elizayo.
Ukunyuka kwexabiso lezinto eziluhlaza akunciphi
Ukunyuka kwexabiso le-electrode yegraphite kwathunyelwa ngokukhawuleza kumantla ekhonkco lemizi-mveliso.Ukusukela ekuqaleni kwalo nyaka, amaxabiso ezinto eziphambili zemveliso yekhabhoni, njenge petroleum coke, coal tar pitch, calcined coke kunye nenaliti coke, anyuke ngokuqhubekayo, ngokunyuka komndilili ongaphezulu kwe-100%.
Intloko yesebe lethu lokuthenga ikuchaze “njengokunyuka”.Ngokutsho komntu ophetheyo, ngesiseko sokuqinisa umgwebo wangaphambili wemarike, inkampani ithathe amanyathelo afana nokuthenga ngexabiso eliphantsi kunye nokunyusa uluhlu lweempahla ukuhlangabezana nokunyuka kwexabiso kunye nokuqinisekisa ukuveliswa kwemveliso, kodwa ukunyuka okubukhali kwempahla ekrwada. kude ngaphaya kokulindela.
Phakathi kwezinto ezikhulayo, i-naliti ye-coke, njengeyona nto iphambili ye-graphite electrode, inokwenyuka kwexabiso elikhulu, ngexabiso eliphezulu linyuka ngama-67% ngosuku olunye kunye nangaphezulu kwe-300% kwisiqingatha sonyaka.Kuyaziwa ukuba inaliti ye-coke yenza ngaphezulu kwe-70% yeendleko zizonke ze-electrode yegraphite, kwaye imathiriyeli ekrwada ye-ultra-high power graphite electrode yenziwe ngokupheleleyo yi-coke yenaliti, edla iitoni ezi-1.05 ngetoni nganye ye-ultra-high power graphite. i-electrode.
Inaliti ye-coke ingasetyenziselwa kwiibhetri ze-lithium, amandla enyukliya, i-aerospace kunye nezinye iindawo.Yimveliso enqabileyo ekhaya nakwamanye amazwe, kwaye uninzi lwayo luxhomekeke ekuthengisweni kwelizwe eTshayina, kwaye ixabiso layo lihlala liphezulu.Ukuqinisekisa imveliso, amashishini egraphite electrode athatha enye emva kwenye, nto leyo ekhokelele ekunyukeni okuqhubekayo kwexabiso lecoke yenaliti.
Kuyaqondwa ukuba kukho amashishini ambalwa avelisa inaliti ye-coke e-China, kwaye abantu kwishishini bakholelwa ukuba ukunyuka kwexabiso kubonakala ngathi lilizwi eliqhelekileyo.Nangona iingeniso zabanye abavelisi bezinto ezikrwada ziye zaphucuka kakhulu, imingcipheko yemarike kunye neendleko zokusebenza zamashishini ekhabhoni asezantsi ayanda.
