Iimeko zeSicelo seCemented Carbide Composite Rods

Iintonga ezihlanganisiweyo ze-carbide, ezihlala zibizwa ngokucacileyo ngokuthi "ziintonga ze-carbide composite," zimele incopho yobunjineli bezinto eziphathekayo, ezenzelwe ukugqwesa kwezona ndawo zifunwa kakhulu kwimizi-mveliso. Ezi ntonga zakhiwe ngobuchule ngokudibanisa amacebiso aqina kakhulu ekhabhide, aqhele ukwenziwa ngeegranule ze-tungsten carbide okanye ukufakwa okungagungqiyo, kunye ne-matrix eqinile ye-nickel / isilivere (okanye ubhedu) ialloy. Olu lwakhiwo lukhethekileyo oludibeneyo lutshata ubunzima obuphezulu kunye nokumelana nokunxiba kwe-carbide ngokuqina okungaqhelekanga, ukuchasana kwempembelelo, kunye ne-thermal conductivity ye-binder metal. Isiphumo sisixhobo esigqwesa izixhobo zentsimbi eziqhelekileyo kwizicelo ezininzi ezinzima. Iimeko zesicelo eziphambili zala macandelo anamandla afumaneka kumashishini apho ukukhwabanisa okugqithisileyo kunye neempembelelo ziyimingeni yemihla ngemihla.

1. Ukugrunjwa kwe-oyile negesi: ukoyisa i-Subterranean Frontier

Kwicandelo leoli kunye negesi, ukusebenza kakuhle kokomba kunye nexesha elide lesixhobo kubaluleke kakhulu. Iirodi ezihlanganisiweyo ze-carbide zizinto ezibaluleke kakhulu kwi-drill bits, ngakumbi kwi-roller cone bits kunye ne-PDC (i-Polycrystalline Diamond Compact) i-bit substrates. Iingcebiso ze-tungsten carbide ezifakwe kumphezulu wentonga zisebenza njengendawo yokuqala yokudibanisa kunye nokwakhiwa kwamatye. Ziyatyumza kwaye zisila ngelitye lentlabathi elirhabaxa, ilitye eliqinileyo, kunye nolunye ukwakheka komhlaba. Isibophelelo se-nickel/copper alloy binder siqinisekisa ukuba intonga inokumelana neempembelelo ezinkulu zokungcangcazela kunye namaxesha okugoba afunyenwe ngexesha lokomba ngaphandle kokwaphuka. Le ndibaniselwano yandisa ngokubonakalayo ubomi benkonzo ye bit drill, inciphisa ixesha lokuphumla kwiinguqu ezincinci, kwaye yonyusa izinga lokungena lilonke, elikhokelela kugcino lweendleko ezinkulu kwimisebenzi ebiza kakhulu yokomba.

2. Ukucutshungulwa kweMigodi kunye neMineral: Intliziyo yokuNcitshiswa kunye nokuNcitshiswa koBukhulu

Ishishini lezemigodi ngokungathandabuzekiyo ngoyena mthengi mkhulu weentonga ezihlanganisiweyo ze-carbide. Ziyimfuneko kakhulu kuluhlu olubanzi lwezixhobo ezisetyenziselwa ukutyumza, ukucola kunye nokugrumba.

• Oomatshini bokucolwa kunye nokuSila:Izando kunye nezikhonkwane kwizityuli kunye nehammer mill zihlala ziphantsi kwe-abrasion enzima evela ku-ores processing kunye namatye. Ukudibanisa la macandelo ngeentonga ze-carbide composite kwandisa kakhulu ubomi babo bokunxiba, ukugcina ukusebenza kakuhle kunye nokunciphisa ukugcinwa rhoqo.

• Izixhobo zoCwangciso lweNdlela kunye neZixhobo zokuTshintsha:Amazinyo kunye neepeki kwiiplani zendlela, abasebenzi basezimayini bomhlaba, kunye ne-trenchers baxhomekeke kwisakhiwo se-carbide composite ukuqhekeza i-asphalt eqinile, ikhonkrithi kunye nelitye. Iingcebiso ezibukhali, ezinzima ze-carbide zibonelela ngesenzo sokusika, ngelixa umzimba wentonga onzima uthatha ukutshitshiswa kwesiteleka ngasinye.

• Digger kunye neDredger Components:Kwimisebenzi yokucoca isanti, igrabile, okanye iiminerali, iintloko ze-cutter kunye nemilebe yebhakethi zixhotyiswe ngezi ntonga ukuxhathisa i-abrasion engapheliyo evela kumxube we-slurry, ukuqinisekisa ukusebenza okuqhubekayo kwiimeko ezinzima.

3. Ulwakhiwo kunye neTunneling: Ukwakha kunye nokudinwa ngokuchaneka kunye noKuhlala ixesha elide

Kwiiprojekthi zolwakhiwo olukhulu kunye netonela, oomatshini kufuneka bomelele ngendlela emangalisayo. Iirodi ezihlanganisiweyo ze-carbide zibalulekile:

• Oomatshini Bokubhobhoza Betonela (TBMs):Iintloko ezisikiweyo ze-TBM zigcwele ii-disc cutters kunye neepikethi ezihlala ziqiniswa okanye zenziwe ngokupheleleyo kwi-carbide composite. Ziyafuneka ukuze zikruqule ngamatye kunye nomhlaba oxubeneyo, zibonelela ngokumelana nokunxiba okuyimfuneko ukugqiba amatonela amade ngaphandle kokutshintshwa rhoqo komsiki.

• Ukuqhuba imfumba kunye nokuGwaba:Izixhobo ezisetyenziselwa ukombiwa kwesiseko kunye nokugalela kumhlaba onamatye inzuzo ngokuqukwa kwezi ntonga. Zikhusela imida ehamba phambili yezixhobo zokugqoka ngokukhawuleza, ziqinisekisa ukuchaneka kwe-dimensional kunye nokunyaniseka kwesakhiwo semingxuma edibeneyo.

4. Ewer Izahlulo koomatshini obunzima kunye nokuVeliswa

Ngaphaya kwemizi-mveliso ephambili ekhankanyiweyo, ezi rodi zidibeneyo zifumana usetyenziso olukhethekileyo njengeenxalenye zokunxiba kwiimeko ezahlukeneyo zobunzima. Zisetyenziswa njengezikhokelo, iilayini, kunye nemicu yokunxiba kwizixhobo zokuphatha izinto ezirhawuzelayo, ezinje ngoomatshini bokuqhumisa, iinkqubo zokuphatha isanti, kunye noomatshini bezolimo abanjengokusasazi isichumiso kunye nezixhobo zokulinywa komhlaba. Ukukwazi kwabo ukuxhathisa ukwakhiwa kwezinto kunye nokugcina indawo egudileyo kuxabiswa kakhulu.

Ukuqukumbela, iintonga ezihlanganisiweyo ze-carbide azikho nje izinto eziphathekayo kodwa isisombululo esibalulekileyo sobunjineli. Ngokudibanisa i-synergistically iipropati ze-tungsten carbide kunye ne-ductile metal binder, zihambisa ukudibanisa okungenakulinganiswa kobunzima kunye nokuqina. Iimeko zabo zesicelo zijoliswe kwiimeko apho iindleko zokunciphisa ixesha kunye nokutshintshwa kwenxalenye ngenxa yokugqoka kuphezulu. Ezi rodi zidibeneyo zibalulekile ekuqhubeni inkqubela, ekwandiseni imveliso, kunye nokuqinisekisa ukuthembeka kwamashishini anzima kwihlabathi liphela.
