Cov khoom siv ntawm covDej zoo dthib qho me meyog ua los ntawm ntau cov ntaub ntawv hlau. Cov khoom siv ntawm covMe ntsisyog qhov pib tshaj plaws los xyuas kom meej lub neej pabcuam ntawm laum me ntsis.
Lub hauv paus ntsiab lus ntawm cov khoom xaiv ntawmDej kom zoo me ntsissYuav kom tawv thiab hnav-resistant thiab muaj cov thev naus laus zis ua tau zoo dua li HB260, tab sis nws yuav tsum tsis txhob cuam tshuam rau ntawm rab riam, thiab tsis muaj peev xwm ua rau muaj riam, thiab tsis yog qhov tsis yooj yim thiab tsis muaj zog yuav tsum ua zoo.
Cov khoom siv uas feem ntau siv rauDej zoo dthkhoomYog cov tawv tawv siab, suav nrog Tungsten Molybdenum, Titanium thiab lwm yam. Cov ntaub ntawv no muaj kev coj zoo thiab corrosion tsis kam, thiab tuaj yeem drilled rau lub sijhawm ntev hauv kev ua haujlwm hnyav.
Tungsten carbide
Tungsten carbide yog cov khoom siv ntau rau kev txiav ntawmDej zoo dth.Nws lub ntsiab lus tseem ceeb suav nrog tungsten, cobalt thiab carbon. Nws muaj lub hardness siab thiab hnav tsis kam, uas tuaj yeem tiv taus qhov kev cuam tshuam loj thiab hnav tau ntsib hauv cov txheej txheem ntawm pob zeb drilling.
Tungsten carbide muaj qhov kub-ua tsis tau zoo thiab ua ib qho nyuaj rau hauv qab-kub thiab kev siv kub siab. Qhov no tso cai rau nws kom muaj kev ruaj khov thaum tsim hluav taws kub thaum tho kev kaw, kom ntseeg tau qhov tseeb thiab ua tau zoo ntawm lub qhov.
Ntxiv mus, nrog lub siab melting taw tes, nws tuaj yeem khaws nws cov duab thiab cov khoom txawm nyob hauv qhov kub siab tsim los ntawm kev sib txhuam ntawm covMe ntsisthiab pob zeb.
Tungsten carbide tuaj yeem hloov kho cov ntaub ntawv nyuaj, xws li sandstone, thiab lwm yam hauv cov ntoo tawv, nws tuaj yeem tswj cov khaub ncaws tawv, nws tuaj yeem txo cov hnav zooDTH, thiab ntev lub neej pabcuam.
Txawm li cas los xij, vim qhov xav tau ntawm cov txheej txheem nyuaj xws li kub siab thiab kev kub siab thaum tsim khoom, tus nqi ntawm cov tawv tawv laum yog qhov siab.
Hlau
Lub cev ntawm lubDej kom zoo me ntsis Feem ntau yog ua los ntawm cov qib siab - lub zog hlau. .Steel muab cov qauv tsim nyog ntawm cov qauv kev ntseeg siab thiab tawv rau tusDej kom zoo me ntsis Cov. Vim tias nws lub siab tawv, nws muaj kev txiav txim zoo txiav. Nws tuaj yeem tiv thaiv cov kev ntxhov siab txhua lub sijhawm thaum lub sijhawm khiav tawm, xws li cuam tshuam los ntawm rab rauj me nyuam thiab tutorional thov thaum sib hloov.
Cov qhab nia sib txawv ntawm cov hlau yuav siv nyob ntawm cov ntaub ntawv tshwj xeeb thiab cov cai kom muaj zog, durability, thiab corrosion tsis kam.
Cobalt - raws li alloys
Ib coDTHYuav ua ke cobalt - raws li cov thoob plaws, tshwj xeeb tshaj yog nyob rau thaj chaw uas xav tau siab kub - Kuj thiab hnav - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam - Tsis kam.
Cobalt - raws li cov tuaj yeem txhim khu kev ua haujlwm ntawm lubDej kom zoo me ntsis Nyob rau hauv heev drilling tej yam kev mob, xws li thaum drilling los ntawm kev nyuaj thiab cov pob zeb abrasive ntawm kev kub ceev.
Hauv cov ntsiab lus, tusDej kom zoo me ntsis Puas yog cov cuab yeej tseem ceeb rau kev ua haujlwm drilling, feem ntau ua los ntawm cov khoom nyuaj-hardness alloys thiab lwm cov ntaub ntawv hlau. Cov ntaub ntawv no ua rau pom cov khoom zoo heev thiab corrosion tsis kam, ua tau zoo hauv kev ua haujlwm hnyav.
Xaiv cov ntaub ntawv tsim nyog thiab cov txheej txheem tsim khoom lag luam tuaj yeem txhim kho kev ua tau zoo thiab qhov zoo ntawm covDej kom zoo me ntsis , yog li ua tau zoo txhim kho kev ua haujlwm tau zoo thiab kev nyab xeeb ntawm kev ua haujlwm drilling.
