Mining Tapered Drilling Rods rau cov cuab yeej tsuas
Nta
• Cov laum rods raug rau cov txheej txheem carburizing los ua kom cov tawv nqaij tawv, ua rau hnav zoo dua thiab ua haujlwm ntev dua.
• Cov khoom siv laum yog 23CrNi3Mo, uas yog piv rau Sandvik Sandbar 64.
• Tus nqi qis, ua haujlwm zoo ntawm tus nqi tsim nyog.
• Ntau yam laum pas nrig rau ntau qhov xwm txheej drilling.
Txhawm rau kom ua tau zoo heev, cov txheej txheem carburization feem ntau yog siv los tsim cov kab loj loj. Txhawm rau muab qhov chaw sab nraud npog tag nrho cov pas nrig nto, carburizing yog siv los ua kom tag nrho cov pas nrig. Feem ntau ntawm cov ntawv thov hauv av thiab qhov chaw uas dej siv los ua cov dej ntws nruab nrab siv carburized steels. Txhawm rau txo qhov brittleness ntawm laum steels, cov txheej txheem siab zaus yog siv feem ntau hauv kev tsim cov kab me me. Tsuas yog cov threaded kawg ntawm tus pas nrig yuav tsum tau hardened siv high zaus. Qhov no ua rau kom cov khoom ua tau ntev thiab ua rau nws zoo dua rau kev xav tau ntau dua qhov kev xav tau. Thawj daim ntawv thov rau cov hlau ua siv cov txheej txheem no yog qhov chaw drilling, qhov twg huab cua ua haujlwm ua qhov nruab nrab flushing.
Peb lub luag haujlwm:
Tsom ntsoov rau qhov xav tau ntawm cov neeg siv khoom drilling thiab cov kev cov nyom, thiab txuas ntxiv pab lawv txo qhov drilling
cov nqi thiab tsim cov khoom tsim tau ntau dua. Ua kom cov drilling ua haujlwm zoo dua.
Drilling khoom rau pob zeb Lub hexagonal chuck seem ntawm tapered laum pas nrig muab leverage rau kev sib hloov chuck bushing. Nws feem ntau muaj lub dab tshos forged kom lub ntsej muag shank tawm tsam hauv lub pob zeb laum nyob rau hauv txoj hauj lwm kom zoo, nrog rau ib tug tapered laum ntsis kawg. Qhov ntev ntawm tapered steel yog ntsuas los ntawm dab tshos mus rau qhov kawg me ntsis. Txhawm rau kom haum raws li qhov ntev ntawm cov pa noj, qhov feem ntau yog drilled hauv 0.6 m increments. Cov hlau drilled raug tshem tawm, thiab cov hlau ntev tom ntej hauv qhov sib lawv liag yog drilled nrog me ntsis txoj kab uas hla pob zeb laum me ntsis.
