Kukho isikhewu kwiNtengiso yeGrrite ye-Electrode, kwaye ipatheni yokuNikezelwa okufutshane iya kuqhubeka

Imakethi ye-elektrode ye-graphite, eye yala kunyaka ophelileyo, yenze utshintsho olukhulu kulo nyaka.
"Kwisiqingatha sokuqala sonyaka, ii-electrode zethu zazingafumaneki." Njengoko umsantsa wentengiso kulo nyaka umalunga neetoni ezingama-100,000, kulindelwe ukuba obu budlelwane buqinileyo phakathi konikezelo kunye nemfuno buya kuqhubeka.

Kuyaqondakala ukuba ukusukela ngeyoMqungu kulo nyaka, ixabiso le-graphite electrode belinyuka ngokuqhubekekayo, ukusuka malunga ne-18,000 yuan / itoni ekuqaleni konyaka ukuya malunga ne-64,000 yuan / itoni okwangoku, ngokunyuka okungama-256%. Kwangelo xesha, i-coke yenaliti, njengezona zinto zibalulekileyo ze-graphite electrode, sele inqabile, kwaye ixabiso layo belinyuka yonke indlela, ethe yonyuka ngaphezulu kwe-300% xa kuthelekiswa nokuqala konyaka.
Ibango lamashishini esinyithi asezantsi lomelele

I-graphite electrode ikakhulu yenziwe nge-petroleum coke kunye ne-coke yenaliti njengezinto ezingafunekiyo kunye ne-tar tar pitch njenge-binder, kwaye isetyenziswa kakhulu kwiziko le-arc elenza i-ironmaking, i-arc furnace, i-furnace, njl njl. I-graphite electrode yokwenza i-akhawunti yentsimbi malunga ne-70% ukuya Iipesenti ezingama-80 zokusetyenziswa ngokupheleleyo kwegraphite electrode.
Ngo-2016, ngenxa yokwehla kwe-EAF yokwenza intsimbi, ukusebenza ngokukuko kwamashishini ekhabhoni kuye kwehla. Ngokwezibalo, inani lokuthengisa lilonke le-graphite electrode e-China lehle nge-4.59% ngonyaka-ngo-2016, kwaye ilahleko iyonke yamashishini alishumi aphezulu e-graphite electrode ayengama-222 ezigidi ze-yuan. Lonke ishishini lekhabhoni lilwa imfazwe yamaxabiso ukugcina isabelo sayo sentengiso, kwaye ixabiso lokuthengisa le-graphite electrode liphantsi kakhulu kunexabiso.

Le meko itshintshiwe kulo nyaka. Ngokunyuka kokulungiswa kwecala lokubonelela, ishishini lesinyithi kunye nentsimbi liyaqhubeka nokuthatha, kwaye "umcu wentsimbi" kunye nomgangatho ophakathi ococekileyo ucoceke walungiswa kwiindawo ezahlukeneyo, imfuno yamaziko wombane kumashishini esinyithi andile. kabukhali, ngaloo ndlela kuqhuba imfuno yee-electrode ze-graphite, kunye nemfuno eqikelelweyo yonyaka yeetoni ezingama-600,000.

Okwangoku, kukho amashishini angaphezu kwama-40 anamandla emveliso yegraphite elektroni agqithe iitoni ezili-10 e-China, enesakhono sokuvelisa esimalunga ne-1.1 yezigidi zeetoni. Nangona kunjalo, ngenxa yempembelelo yabahloli bokhuselo lokusingqongileyo kulo nyaka, amashishini emveliso ye-graphite electrode e-Hebei, Shandong nase-Henan amaphondo akwimeko yokuveliswa kwemveliso kunye nokumiswa kwemveliso, kunye nemveliso yonyaka ye-graphite electrode eqikelelwa kwi-500,000 yeetoni.
"Isithuba sentengiso esimalunga neetoni ezingama-100 000 asinakusonjululwa ngamashishini anyusa amandla emveliso." U-Ning Qingcai uthe umjikelo wokuveliswa kweemveliso ze-graphite electrode ngokubanzi ngaphezulu kweenyanga ezimbini okanye ezintathu, kwaye ngomjikelo wesitokhwe, kunzima ukwandisa ivolumu kwixesha elifutshane.
Amashishini eCarbon ayinciphisile imveliso kwaye avaliwe, kodwa ibango lamashishini esinyithi liyanda, okukhokelela ekubeni i-graphite electrode ibe yimpahla eqinileyo kwintengiso, kwaye ixabiso layo belinyuka yonke indlela. Okwangoku, ixabiso lentengiso lenyuke ngama-2.5 amaxesha xa kuthelekiswa noJanuwari walo nyaka. Amanye amashishini esinyithi kufuneka ahlawule kwangaphambili ukuze afumane iimpahla.

Ngokutsho kwangaphakathi kwishishini, xa kuthelekiswa nokuqhuma kwesithando somlilo, isinyithi somlilo sombane sinokugcina amandla, ukulungeleka kwendalo kunye nekhabhoni ephantsi. Nge China ingena kumjikelo wokuhla kwexabiso lokulahla, isinyithi somlilo sombane siya kufezekisa ukukhula okukhulu. Kuqikelelwa ukuba umyinge wayo kwimveliso yentsimbi iyonke kulindeleke ukuba inyuke ukusuka kwi-6% ngowama-2016 ukuya kuma-30% ngowama-2030, kwaye ibango lee-graphite electrode liselikhulu kwixesha elizayo.
Ukunyuka kwamaxabiso ezinto ezisetyenziswayo ezingaphumiyo akwehli

Ukunyuka kwamaxabiso e-graphite electrode kwadluliselwa ngokukhawuleza kumjelo wenyani yoshishino. Ukusukela ekuqaleni kwalo nyaka, amaxabiso ezinto ezingafunekiyo kwimveliso yekhabhon, efana ne-petroleum coke, i-tar tar pitch, i-coke ye-calcined kunye ne-coke yenaliti, anyuke ngokuqhubekayo, ngokunyuka okuphakathi kwe-100%.
Intloko yesebe lethu lokuthenga ichaze "njengokunyuka". Ngokomntu ophetheyo, kwisiseko sokomeleza isigwebo sentengiso, inkampani ithathe amanyathelo njengokuthenga ngexabiso eliphantsi kunye nokwandisa uluhlu lwempahla ukujamelana nokunyuka kwamaxabiso kunye nokuqinisekisa imveliso, kodwa ukunyuka okubukhali kwezinto ezingafunekiyo kude ngaphaya kokulindelweyo.
Phakathi kwezinto ezivelayo ezikhulayo, i-coke yenaliti, njengeyona nto iphambili ekrwada ye-graphite electrode, enelona xabiso likhulu lokunyuka, elona xabiso liphezulu lenyuka ngama-67% ngosuku olunye nangaphezulu kwama-300% kwisiqingatha sonyaka. Kuyaziwa ukuba iiakhawunti ze-coke yenaliti ngaphezulu kwe-70% yexabiso lilonke le-graphite electrode, kwaye izinto ezingafunekiyo ze-ultra-high power graphite electrode yenziwe ngokupheleleyo ngenaliti yecoke, echitha iitoni eziyi-1.05 ngetoni nganye yamandla aphezulu egrafayithi i-electrode.
I-coke yenaliti inokusetyenziselwa iibhetri ze-lithium, amandla enyukliya, i-aerospace kunye nezinye iinkalo. Yimveliso enqabileyo ekhaya nakumazwe aphesheya, kwaye uninzi lwayo luxhomekeke kuthengiso ngaphakathi e-China, kwaye amaxabiso alo ahlala ephezulu. Ukuqinisekisa ukuveliswa, amashishini e-graphite electrode athabatha enye emva kwenye, ekhokelele kukonyuka okuqhubekayo kwexabiso le-coke yenaliti.
Kuyaqondakala ukuba kukho amashishini ambalwa avelisa i-coke yenaliti e-China, kwaye abantu abakweli shishini bakholelwa ukuba ukunyuka kwamaxabiso kubonakala ngathi lilizwi eliqhelekileyo. Nangona iinzuzo zabanye abavelisi bezinto ezingafunekiyo ziphuculwe kakhulu, umngcipheko wentengiso kunye neendleko zokusebenza kwamashishini eekhabhon ezantsi ziya zisanda.
