1. Wireline laum yeeb nkab yog tsim los ntawm cov kav dej tshwj xeeb geological steel nrog lub zog siab thiab cuam tshuam toughness;
2. Peb tuaj yeem suppl wireline laum rods nrog AQ, BQ, NQ, HQ, PQ, AW, BW, NW, HW, HWT, PW, PWT thiab lwm yam nkoj longyear standard qhov ntau thiab tsawg thiab 1.5m, 3 meters ntev;
3. Tsuas yog rau cov kav dej laum, peb kuj muab cov khoom siv impregnated, casing khau, reaming shells thiab lwm yam.

U85 AUS16NB thee mine laum ntsis yog tsim los ntawm 42CrMo thiab YG11C cov lus qhia carbide.
nws yog dav siv nyob rau hauv underground coal mining. Txais cov khoom siv raw thiab cov txheej txheem tsim khoom siab heev los tsim.
Zoo zoo thiab nruj tswj qhov system ua rau peb cov khoom tau txais lub koob npe nrov.

Tydrillbits muab txoj kev milling khoom nrog cov lus qhia tungsten carbide.
Cov carbide txais yuav YG8, YG11C los yog sib tham. Bit lub cev txais 42 CrMo steel. Peb muaj ntau tshaj li 7 xyoo kev paub ntawm kev muab cov khoom siv laum.

1308 Spherical PDC Cutters txais pob zeb diamond hmoov thiab tungsten carbide substrates raws li nws cov khoom siv raw,
nws yog ib qho khoom siv complex uas yog ua nyob rau hauv qhov kub thiab txias sintering.
Ua ke lub hardness, hnav-tiv taus thiab thermal conductivity nrog rau siab toughness thiab lub zog ntawm tungsten carbide.
