Ngenxa yokwenyuka kwentengo ye-tungsten carbide, into ebalulekile ye-roller cone kanye nama-PDC bits, izindleko zokukhiqiza zikhuphuke kakhulu. Amanani ezinto ezingavuthiwe ayaqhubeka nokwenyuka, okwenza isimo sibe sibi kakhulu. Impahla yethu isicishe iphele. Ukuze sibhekane nalezi zinselele, sizolungisa amanani ama-bits ethu. Siyakwazisa ukuqonda kwakho njengoba silwela ukugcina ikhwalithi.
Ukwanda kwamuva nje kwentengo ye-tungsten carbide kuvela ezintweni eziningi ezixhumene. Imikhawulo yokuphakelwa iyabusa, njengoba iShayina—ekhiqiza u-82.7% we-tungsten yomhlaba wonke—ibeke izilawuli eziqinile zokuthumela kwamanye amazwe emikhiqizweni ye-tungsten eluhlaza njenge-ammonium paratungstate (APT) kanye ne-tungsten oxide ngoFebhuwari 2025, yehlisa ukuthunyelwa kwamanye amazwe ngaphezu kuka-80%. Ngesikhathi esifanayo, iqembu layo lokuqala lezabelo zezimayini ze-tungsten zango-2025 lehle ngo-6.45% unyaka nonyaka, kanti iSifundazwe saseJiangxi sinciphise umkhiqizo ngo-10%. Lokhu kucindezela kwenqubomgomo okubili kushiye izimakethe zomhlaba zicindezelekile, ikakhulukazi njengoba amazwe aseNtshonalanga elwela ukuthatha indawo yezimpahla zaseShayina.
Izingcindezi ezihambisana nesidingo nazo zibaluleke kakhulu. Imikhakha emisha yamandla, okuhlanganisa izintambo ze-tungsten ze-photovoltaic (ukungena okungaphezu kuka-12%) kanye ne-nuclear fusion reactors ezidinga amathani angu-3,000 e-tungsten, kwaqhuba ukusetshenziswa okungakaze kubonwe ngaphambili. Isidingo sezempi sanda naphakathi kokungezwani kwezepolitiki, kuyilapho ukukhiqizwa okuphezulu—njengamathuluzi e-carbide anembile ama-EV namarobhothi ezimboni—kwaqinisa izinhlelo zokusebenza ze-premium. Ukuqoqwa okuqagelwayo ngabaphakeli kwandise ukushoda, kwathi amanani empuphu ye-tungsten afinyelela ku-364 yuan/kg ngoJuni 2025. Naphezu kokulungiswa kwemakethe yesikhashana, ukushoda kwesikhathi eside kanye nokugcinwa kwesu yi-EU kanye ne-US kusikisela ukuthi kuqhubeke nokukhula.
Ngenxa yezizathu zokwenyuka kwezindleko ze-tungsten carbide, intengo yama-drill bits ishintshiwe. Uma ufaka i-oda, sicela uthintane nentengo yakamuva.
