Ho tloha bofelong ba May ho ea qalong ea June, potoloho e ncha ea phetoho ea theko ea 'maraka oa nale ea coke e tla kenngoa. Leha ho le joalo, hona joale,' maraka oa nale o laoloa ke boikutlo ba ho leta le ho bona. Ntle le likhoebo tse ling tse nchafatsang theko ka Phuptjane 'me li etelletse pele ka ho nyolla li-yuan tse 300/ton, khoebo ea 'nete ea lipuisano ha e so fihle. Theko ea 'maraka oa nale ea China e lokela ho sebetsa joang ka Phuptjane,' me e ka tsoela pele ka mokhoa o ntseng o phahama ka Mots'eanong?
Ho tloha mokhoeng oa theko ea nale coke, ho ka bonoa hore theko ea nale coke e tiile 'me e phahame ho tloha ka March ho ea ho April, ebe e lula e tsitsitse ka mor'a ho sutumetsa qalong ea May. Ka May, theko e tloaelehileng ea coke e thehiloeng ka oli ke 10,500-11,200 yuan/ton, ea coke e thehiloeng ka oli ke 14,000-15,000 yuan/ton, ea coke e entsoeng ka mashala ke 9,000-10,000 yuan/ton, le ea coke e entsoeng ka mashala ke 12,200 yuan/ton. Hajoale, ho na le mabaka a 'maloa a hore nale coke e eme le ho bona:
1. Theko ea coke ea petroleum e tlaase-sulfur e theohile. Ho elella bofelong ba Mots'eanong, theko ea coke e tloaelehileng ea sebabole ea sebabole e Dagang le Taizhou e ile ea etella pele, 'me joale Jinzhou Petrochemical ea latela. Ka la 1 Phuptjane, theko ea Jinxi Petrochemical e theohile ho 6,900 yuan/ton, mme phapang ea theko lipakeng tsa Daqing le Fushun coke ea boleng bo holimo ea petroleum e ile ea atolosoa ho 2,000 yuan/ton. Ka ho fokotseha ha coke e tlase ea sulfur petroleum, likhoebo tse ling tse tlase li ile tsa eketsa karolelano ea motsoako oa petroleum coke, e ileng ea ama tlhokahalo ea nale ho isa bohōleng bo itseng. Indasteri ea nale ea coke e lokela ho bua ka theko ea petroleum coke e Daqing le Fushun. Hona joale, ha ho na khatello ho li-stocks tse peli, 'me ha ho na moralo oa ho fetoha o theoha, kahoo maraka oa nale ea coke o tla ema ebe o bona.
2. Tlhokahalo ea theko ea li-electrode e tlase e fokotseha. Tlas'a tšusumetso ea boemo ba seoa, litaelo tsa libeteri tsa matla le libeteri tsa digital li ile tsa theoha ka May. Lisebelisoa tse tala tsa nale coke ea lisebelisoa tsa anode li ne li cheka haholo qalong, mme palo ea litaelo tse ncha e fokotsehile. Likhoebo tse ling, haholo-holo tsa nale e entsoeng ka mashala, li ile tsa eketsa thepa ea tsona.
3. Phallo ea electrode ea graphite e ile ea lula e le tlaase. Phaello ea lichelete tsa tšepe e futsanehile, 'me likhoebo tsa graphite electrode li angoa ke boemo ba seoa, tšireletso ea tikoloho le theko e phahameng ea thepa e tala, kahoo cheseho ea bona ea ho qala kaho ha e phahame mme tlhahiso ea bona e tlaase. Ka hona, tekanyo ea nale coke e batla e bataletse. Likhoebo tse ling tse nyane tsa tlhahiso li sebelisa coke ea petroleum e nang le sulfur e tlase sebakeng sa nale coke.
Tlhahlobo ea pono ea 'maraka: Ka nako e khuts'oane, likhoebo tsa anode li cheka setoko sa thepa e tala qalong, ebe li saena liodara tse ncha tse fokolang. Ho phaella moo, theko ea merabe ea low-sulphur petroleum coke bureau e tla ba le tšusumetso e itseng ho romelloeng ha nale coke. Leha ho le joalo, likhoebo tsa nale coke li na le litšenyehelo tse phahameng tsa tlhahiso, 'me ha ho na monyetla oa hore theko e oele tlas'a khatello ea phaello. Ka hona, 'maraka oa nale oa coke o tla tsoela pele ho busa ka June boemong ba ho leta le ho bona. Ha nako e ntse e ea, ka boemo ba seoa ba Shanghai le libakeng tse ling tse laoloang, tlhahiso ea likoloi e lebelletsoe ho fola butle-butle, 'me tlhoko ea ho qetela e lebelletsoe ho eketseha. Ntle le moo, karolong ea boraro, lisebelisoa tse ling tse mpe tsa li-electrode li ntse li tla kengoa tlhahiso, tse tla eketsa tlhokahalo ea lisebelisoa tse tala tsa nale. Ha likhoebo tse mpe tsa li-electrode li qala ho boloka thepa e tala, boemo bo thata ba nale coke bo tla boela bo thehe tšehetso e ntle bakeng sa litheko.
