Khoom Paub meej:
7 degree tapered laum pas nrig 7 degree rau mining
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 tau zoo dua.
Carburization yog txheej txheem uas ntxiv dag zog rau thiab txuas ntxiv lub neej ntawm tapered laum rods los ntawm hardening lawv tag nrho nto, sab hauv thiab sab nraud.
Lub taper laum pas nrig xa lub zog los ntawm lub pob zeb laum mus rau qhov me ntsis thaum nws txuas nrog rau ib sab ntawm lub pob zeb laum thiab lwm sab ntawm ib qho taper laum me ntsis. Txoj kev loj hlob ntawm ib qho kev xyaum rods yog tapered laum pas nrig. Txhawm rau kom lub shank nyob rau hauv txoj hauj lwm kom raug ntaus lub ntsej muag ntawm lub pob zeb xyaum, nws feem ntau muaj ib tug forged dab tshos. Kev siv tau ntev ntawm tapered laum rods, uas feem ntau yog los ntawm 0.6 mus rau 3.6 meters los ntawm dab tshos mus rau qhov kawg me ntsis, yog ntsuas li no.
Qhov kawg tsav ntawm drifting laum steel yog feem ntau tsoo kom muaj zog ntxiv ntawm lub pob zeb laum kawg txhawm rau kom haum rau txoj kab uas hla loj thiab shank adapters. Laum steel rau pob zeb drilling cov cuab yeej tau yooj yim muaj nyob rau hauv ntau tus qauv ntev, thiab tuaj yeem sib phim rau cov laum pub rau ntawm ntau cov jumbos drifting uas tam sim no muaj. Nws tuaj yeem siv lub pob zeb laum me ntsis nrog txoj kab uas hla uas zoo ib yam li cov hlau txoj kab uas hla, txhim kho qhov dej ntws thiab qhov raug, vim tias qhov sib txuas tsis nkag mus rau hauv lub qhov.
Loj: 22 * 108 hli, 25 * 108 hli, 25 * 159 hli; 6, 7, 11, 12 degree taper nyob rau hauv feem ntau ntev; laum steel taper degree feem ntau yog tuaj txawv teb chaws rau kev ua haujlwm zoo drilling.
Tapered laum pas nrig, tseem hu ua tapered laum steels, yog ib hom ntawm tes tuav pob zeb xyaum siv nyob rau hauv granite thiab marble quarries, underground mining, thiab rau me me blasting qhov. Taper laum rods xav tau tapered laum khoom, chisel khoom, hla khoom, thiab khawm khoom siv ua ke. Taper laum rods tuaj nyob rau hauv ntau lub ces kaum; Lub teeb lub luag haujlwm pob zeb xyaum siv feem ntau siv 7 taper lossis lub kaum sab xis me, thaum lub luag haujlwm hnyav pob zeb feem ntau siv lub kaum sab xis 11,12 taper.
