Guteza imbere uburyo bwo kurwanya ingaruka ku bacukuzi b'amabuye y'agaciro: Impuguke y'imyaka 10 muri Amerika yatanze ubuhamya ku ikoreshwa rya Diamond Enhanced Compact (DEC)
Nyuma y'imyaka icumi nkora akazi ko gucukura amabuye y'agaciro muri Amerika, nabonye ibibazo byinshi bituruka ku kudashobora gukata ibintu mu buryo buhanitse—uducukuzi twakozwe mu gihe cyo gucukura amabuye akomeye muri Colorado, igihe gihoraho cyo gusimbuza mu birombe by'amakara byo muri Texas, ndetse n'ibiciro by'imikorere bizamuka cyane bituma abayobozi b'ibirombe batinya. Ariko umukino warahindutse ubwo ikoranabuhanga rya diyama ryazamuye (DEC) ryagendaga rikura, cyane cyane bitewe no gukoresha cyane diyama ya Conical. Nk'umuntu wanduye mu birombe byo munsi y'ubutaka no mu nganda zikora muri Amerika, reka nsobanure uburyo iki gicuruzwa cyahinduye uburyo kidakoresha diyama mu buryo buhanitse.
Ubukorikori bwagaragaye: Umugongo wa Diyama ifite imiterere y'ibumba yarushijeho kwangirika
Mu rwego rw'ubucukuzi bw'amabuye y'agaciro muri Amerika, tubaho dukurikije amagambo agira ati “nta nzira z'ubusa ku mikorere”—kandi diyama yongerewe imbaraga ya Conical diyama irabitanga. Urufunguzo rw'ubukomere bwayo ruri mu gukora neza, ibyo nabibonye ubwanjye mu gihe nasuraga uruganda. Ikintu cy'ingenzi cyane mu kurwanya ingaruka z'icyuma ni isano iri hagati y'urwego rwa diyama na carbide, ikintu nagerageje kenshi. Iki gicuruzwa gikoresha ikoranabuhanga rya polycrystalline diyama, hamwe n'ubushyuhe n'umuvuduko bipimwa kugeza ku bice bya dogere na psi—ikintu Amerika icukura gisaba ko habaho uburinganire.
Guhitamo ibikoresho fatizo nabyo birakomeye cyane: ubuziranenge bwa diyama bugera kuri 99.9%+, kandi ubukana bwa carbide substrate bukorerwa ibizamini bitatu bya ASTM. Ndetse niboneye uburyo bwo kugenzura ubuziranenge bwabo: buri gice cya Conical diamond compact ikomeza gukubita amabuye akomeye inshuro 5.000 binyuze mu gukandagira amazi - nta mvune, nta bishishwa, nta kunyura. Ubwo ni bwo bwoko bw'ubukorikori butuma habaho imikorere ifatika. Mu kibaya cy'uruzi rwa Powder muri Wyoming, ibi bivuze ko icyuma gikata gikwirakwiza imbaraga z'impanuka ku buryo bungana, cyirinda gutsindwa gukomeye ku buryo buhendutse. Ntabwo ari "cyakozwe neza gusa" - cyubatswe kugira ngo kibeho mu bihe bibi abacukuzi b'amabuye y'agaciro bo muri Amerika bahura nabyo buri munsi.
Igishushanyo mbonera cyubatswe ku ntego: Imashini ntoya ya Diyama ifite imiterere y'inyuguti ijyanye n'imiterere ikomeye ya Amerika
Ubucukuzi bw'amabuye y'agaciro muri Amerika buzwiho kutababarira—kuva ku ibuye ry'umucanga rinini ryo muri Utah kugeza ku mabuye y'agaciro menshi yo muri Kaliforuniya, abakata bahura n'ibice byoroshye n'ibikomeye bisimburana bigaragaza ko ibintu byakozwe nabi bitameze neza. Imiterere y'agace gato k'icyuma gafite diyama ifite imiterere iciriritse irahindura ibintu, yakozwe hifashishijwe imiterere ya Amerika. Mu buryo bwa mekanike, imiterere y'agace k'icyuma ituma agace k'icyuma karuma ibuye vuba, bigabanya uburemere bw'inkongi, mu gihe ubugari bw'agace k'icyuma gakozwe neza bwongeraho ingabo ikomeye aho igera ku muvuduko mwinshi—ibisobanuro nagenzuye mu igeragezwa ryo mu murima muri Arizona.
Fata ubwoko bwa C3129 na C0609 bwa diyama ifite imiterere yoroheje, ikora cyane mu birombe byo muri Amerika. Mu kirombe cy’amabuye akomeye cya Colorado, C3129 yakoreye amasaha 8 yikurikiranya nta kwangirika—ugereranije n’amasaha 3 ku bacukuzi basanzwe. Mu kirombe cy’amakara kiri munsi y’ubutaka cya West Virginia, C0609 yakoreshaga shale na limestone zisimburana, yongera ubuzima bwa serivisi ku kigero cya 40% ugereranije na DEC zisanzwe. Ibi si ubuhanga gusa; imiterere yayo ishingiye ku gusobanukirwa ibibazo by’ubucukuzi muri Amerika. Ku bacukuzi b’amabuye y’agaciro hano, bivuze ko igihe cyo gukora kigabanuka, abasimbura bake, n’amatoni menshi yimuwe—ni byo dukeneye kugira ngo dukomeze guhangana.
Ibisubizo byagaragaye mu buryo bufatika: Diyama ntoya yongerewemo imiterere y'amabuye y'agaciro yagabanyije ikiguzi cy'ibirombe byo muri Amerika
Nk'impuguke yo muri Amerika, ndahiye gusa ibicuruzwa bitanga aho hantu—kandi kompanyi ya Conical diamond yatsinze ikizamini mu birombe birenga 30 hirya no hino mu gihugu, kuva mu birombe by'amakara bya Appalachian kugeza mu birombe by'ibyuma bya Nevada. Ibitekerezo ni rusange: kurwanya ingaruka nziza, kugabanuka kw'impinduka, no kuzigama amafaranga menshi. Umucukuzi w'amabuye y'agaciro muri Texas yambwiye ko guhindura ibi bicuruzwa byagabanyijeho 6 buri kwezi, kongera umusaruro w'ibikoresho ku kigero cya 25%, no kuzigama hafi $300.000 buri mwaka—imibare igaragara cyane mu nganda z'ubucukuzi bw'amabuye y'agaciro zo muri Amerika zikora cyane.
Ikindi kandi, uruganda rukora ibikenewe mu birombe byo muri Amerika rufite imiterere isanzwe ya 19mm, 16mm, 13mm, n'izindi ngano zisanzwe zo muri Amerika, hamwe n'ubugari bwa diyama bugenewe imiterere yihariye. Mu nama nagiranye n'iki kigo, itsinda ryanjye ryasanze guhuza ibicuruzwa n'amabwiriza y'uruganda (yakozwe hifashishijwe ibikoresho byo muri Amerika) bigabanya imyanda ku kigero cya 30%. Ubwo ni bwo buryo bw'ubufasha bufatika butandukanya diyama ya Conical na diyama—nta magambo menshi avugwa, ahubwo ni ibisubizo bikora ku bikorwa by'ubucukuzi muri Amerika.
Mu bucukuzi bw'amabuye y'agaciro muri Amerika, kurwanya ingaruka si ikintu cy'agaciro—ni ngombwa. Imashini ntoya ya diyama ifite ishusho y'igiti itanga ubuhanga bufatika, imiterere yihariye, n'umusaruro ugaragara ku bacukuzi. Niba ikirombe cyawe cyo muri Amerika kirambiwe n'igabanuka ry'ibiciro rihenze ry'ibikoresho byo gukata no kudakora neza, iki gicuruzwa si ukuvugurura gusa—ni icyemezo cy'ubucuruzi gikozwe neza.
Kugira ngo umenye byinshi kuri kontineri ya Conical diamond igezweho cyangwa kugira ngo uganire ku bisubizo byihariye ku bucukuzi bwawe bwo muri Amerika, hamagara:
