Cov neeg xav tau, nrog rau txoj kev tsim kho ntawm kev tsim kho tshiab, kev sib tw rau kev ua lag luam tseem tsim tawm ntxiv. Hammerhead manufacturers tau teb rau ntau cov kev xav tau thiab ua nruj ua luaj tsim ib pawg ntawm hammerheads nrog cov khoom sib txawv. Txhua hom hammerhead yog txawv ntawm kev hnav ua haujlwm thiab tawv nqaij. Uas ua rau siab-chromium muab tauj?
Raws li peb txhua tus paub, high-chromium cam khwb cia hlau yog cov khoom siv tawv-resistant nrog cov cuab yeej coj los tiv thaiv zoo heev, tab sis nws muaj tsawg toughness thiab yog nquag txhav tawg. Yuav kom ntseeg tau tias qhov kev lag luam muaj kev ruaj ntseg ntawm high-chromium cam khwb cia hlau hammers, high-chromium Compound hammers tau tshwm sim, uas tau raug kho dua ntawm kev hnav ua haujlwm thiab kev muaj zog.
Hom hammerhead no siab-chromium cam khwb cia hlau mus rau hauv lub taub hau ntawm high-manganese hlau los yog low-alloy steel rauj, los yog siv lub siab-chromium nrum hlau nyob rau hauv kev ua hauj lwm ib feem ntawm cov rauj thiab ib cov pa carbon nyob rau hauv lub tuav rau muab ob sab ua kom hammerhead. Lub taub hau muaj kev kub ntxhov, thiab kev sib tw ua rau lub siab muaj zog, ua kom zoo dua qhov zoo ntawm cov khoom siv ob qho tib si thiab ua kom tsis zoo ntawm cov khoom qub, thiab ua raws li cov kev cai ntawm lub taub hau.
Txawm li cas los xij, lub siab chromium daim hammer muaj ib tug txheej txheem tsim txoj cai thiab cov txheej txheem nruj heev. Raws li daim ntawv tshaj tawm ua ntej ntawm ob peb lub xyoo dhau los, kev ua tiav tag nrho ntawm peb qhov kev paub txog roj rov qab poob qis, qhov ntawm, CNPC qhov nyiaj tau nce los ntawm 5.6% xyoo-rau-lub xyoo, thiab CNOOC qhov nyiaj tau nce ntxiv ntawm 7.9% xyoo -tau-xyoo. Txoj kev lag luam tseem ceeb yog qhov zoo.
