Kuwunikira pa index yamtengo wapatali ya petroleum coke

Mndandanda wa mafuta a petroleum coke ndi ambiri, ndipo pali magulu ambiri. Pakadali pano, gulu la kaboni lokha la aluminiyamu ndi lomwe lingakwaniritse zomwezo mumakampani. Pankhani yazizindikiro, kuphatikiza pazizindikiro zokhazikika za makina oyeretsera, gawo lalikulu la zinthu zapakhomo zimachokera ku makina oyengera am'deralo, ndipo zopangira zopangira zoyenga zapanyumba zimakhala zosinthika, chifukwa chake zizindikiro za mafuta a petroleum coke opangidwa zidzasintha. zisinthidwe kaŵirikaŵiri moyenerera, ndipo mtengowo udzasinthidwa kawirikawiri ndi chitsanzo cha mitengo ya zinthu zoyenga, choncho n’zovuta kupanga chitsanzo chamitengo yokhazikika ndi yogwirizana. Mitengo yafupipafupi ndi yosinthika ndi zizindikiro zimabweretsa kusatsimikizika ndi chiwopsezo pakuwongolera mtengo wa mbali yofunikira yapansi.

Pakalipano, mndandanda waukulu wamagulu a carbon a aluminiyamu ndi sulfure ndi kufufuza zinthu zomwe zimagawidwa m'magulu akuluakulu 7: 1, 2A, 2B, 3A, 3B ndi 3C. Sulfure yoposa 3.0% imayendetsedwa ndi mabizinesi okha. Pakalipano, kugawika kwa mabizinesi ndizovuta, ndipo ambiri aiwo amagwiritsidwa ntchito pofotokoza zamakampani.

Pankhani ya mtengo panopa mu November, sabata yoyamba ya November, mu zoweta kuyenga m'malo zizindikiro zimachitika tsiku lililonse, mlungu ndi mlungu m'malo ndi kusintha index pafupipafupi ndi kuposa 10 nthawi, kusintha indexes mabizinesi wa pafupipafupi chimodzimodzi ndi kusatsimikizika, wachibale. mpaka kumtunda calcination, kufunika monga anode, ndi khola index amafuna kutha, kuyang'ana msika khalidwe ndi ambiri, kusiyana n'zoonekeratu, Zizindikiro kusintha kawirikawiri, ndipo palibe njira ndi muyezo mitengo, zimenezi kuti mafuta coke amafuna mabizinesi kuonjezera. kugula kwa coefficient yovuta kwambiri.

Kutengera mtengo wamsika wamakono monga chitsanzo, mitengo yamtengo wapatali ndi yotsika kwambiri komanso kusiyana pakati pa mitengo yamtengo wapatali ndi yotsika kwambiri yachitsanzo chilichonse ku China kupatula dera la kumpoto chakumadzulo kumayambiriro kwa mwezi wa November akuwonetsedwa mu Table 1. Pakati pawo, kusiyana pakati pa chigawo cha kumpoto chakumadzulo kwa mwezi wa November ndi 1. mtengo wapamwamba kwambiri komanso mtengo wotsika kwambiri wamtundu womwewo ndi 5# petroleum coke, kusiyana kwake ndikwakukulu kwambiri kwa 4A petroleum coke, mitengo yosiyana ndi madera ndi mitundu yosiyanasiyana yazizindikiro zikugwirizana.
