Ngaba Amaxabiso eTungsten Ayaqhubeka Enyuka? Kwaye Ukunyuka Kwamaxabiso Kuchaphazela Njani Umgangatho We-Drill Bit?

Amaxabiso eTungsten akwimeko yokulungiswa kwexesha elifutshane, aphakathi ukuya kwixesha elide, kwaye anciphile kwaye anamandla okunyukela phezulu.

• Ixesha elifutshane (iinyanga ezi-1–2): Emva kokufikelela kwinqanaba eliphezulu lembali ngoMatshi 2026, amaxabiso e-tungsten (umz., i-65% ye-wolframite concentrate) alungisiwe ngaphezulu kwe-33% ekuqaleni kukaMeyi, engena kwinqanaba lokutsala uloyiko kunye nokwehla. Amaxabiso asondela kwiindleko zemveliso yemigodi (~RMB 500,000–600,000/ton ye-concentrate), okushiya indawo encinci yokwehla okukhulu ngakumbi.
• Ixesha eliphakathi (iinyanga ezi-3–6): Ixhaswa kukungabikho kombane oneleyo (izabelo zemigodi zaseTshayina zisalawulwa ngokungqongqo; ukunikezelwa kombane omtsha phesheya kwezilwandle kunqunyelwe kwi-~10,000 yeetoni ngo-2026) kunye nokubuyiselwa kwemfuno (amaxesha aphezulu e-carbide eqinisiweyo kunye nocingo lwe-tungsten lwe-PV), amaxabiso kulindeleke ukuba azinze kwaye abuyele umva ukususela phakathi kuMeyi. Iziganeko ezibalulekileyo ezifana neNkomfa yoShishino lweTungsten yaseTshayina (nge-7–9 kaMeyi) kusenokwenzeka ukuba zibeke ithoni entle kwimarike.
• Ixesha elide (unyaka omnye nangaphezulu): Ingqiqo engundoqo yokuqina kobonelelo kunye nokwandiswa kwemfuno ayitshintshi. Imfuno evela kwi-PV tungsten wire, ii-semiconductors, kunye nokhuselo iya kugcina imakethi iqinile, iqhubela amaxabiso ukuba adlule phezulu ngaphambili.
Ukunyuka kwamaxabiso eTungsten kuyichaphazela njani umgangatho we-Drill Bit?
Amaxabiso e-tungsten anyukayo awanciphisi umgangatho we-drill bit—endaweni yoko, akhawulezisa ukuphuculwa kwemveliso kwaye azinzise umgangatho ophezulu, ngelixa ecinezela amandla aphantsi, akumgangatho ophantsi.
• Umgangatho uhlala uzinzile kwiimveliso zexabiso eliphezulu: I-Tungsten (njenge-tungsten carbide, i-WC) ibandakanya i-75%–92% yokwakheka kwezinto zokubhola kunye ne-40%–60% yeendleko zemveliso. Abavelisi abaphambili (umz., inkampani yethu) basebenzisa iikhontrakthi zokubonelela ixesha elide ukuze bavale i-70%+ yeemfuno zezinto eziluhlaza, bephepha ukwehla kwexabiso lezinto. Ulawulo oluqinileyo lomgangatho kunye neenkqubo eziphambili zokusila/zokufaka i-coating ziqinisekisa ubulukhuni obuhlala buhleli, ukumelana nokuguguleka, kunye nokuqina kwempembelelo.
• Ushishino lutshintshela ekubeni notshintsho, kungekhona ukunciphisa iindleko: Ukuze kuncitshiswe uxinzelelo lweendleko, abavelisi baphucula uyilo (umz., iinkqubo ezitshintshaniswayo ukuze kuncitshiswe ukusetyenziswa kwe-WC nge-30%+ ngaphandle kokunciphisa ukusebenza) kwaye basebenzisa iingubo zokusebenza eziphezulu (umz., i-TiN, i-DLC) ukuze kwandiswe ubomi bezixhobo ngokuphindwe kabini ukuya kahlanu. Olu phuculo lunciphisa iindleko kwaye luphucula ixabiso lilonke.
• Imarike ekumgangatho ophantsi ijongene nokupheliswa komgangatho: Abavelisi abancinci abangenazo izixhobo eziluhlaza banokusebenzisa ii-WC ezikumgangatho ophantsi, umxholo we-WC ophantsi, okanye iingubo ezincinci ukunciphisa iindleko, nto leyo ekhokelela kwiingozi eziphezulu zokuqhekeka, ukuguguleka kwangaphambi kwexesha, kunye nobomi benkonzo obufutshane. Oku kukhawulezisa ukuhlanganiswa kweshishini, kunye neenkokheli ezisemgangathweni zifumana isabelo semarike.
