Ua ntej, qhov sib txawv hauv cov txheej txheem ntau lawm:
(1) Kev sib tsoo pob hlau (pob hlau tsis xeb, pob hlau bearing, pob hlau carbon siab, pob hlau carbon) cov txheej txheem ntau lawm:
Cov khoom siv raw (pas hlau, hlau puag ncig) - hlau rau hlau kos duab - txias taub hau / forging - pob (polishing) - kev kho cua sov - txhim kho kev sib tsoo nyuaj - - - kev tshawb fawb - thaum pib ntawm qhov tsis zoo nrhiav pom rau lub qhov muag liab qab - lapping - ntxuav - tshuaj xyuas - ntim khoom
(2) forging steel pob ntau lawm txheej txheem: cov khoom siv raw puag ncig hlau txiav Lub kaum sab xis - - - - pob dov cua sov / pob forging tshuaj ntsuam - - - - - - txias quenching - tempering - txias - ntim khoom
(3) cov txheej txheem tsim cov pob hlau cam khwb cia: qhov sib piv ntawm cov khoom siv raw - cov ntaub ntawv - qhov nruab nrab zaus cua sov smelting - tuag casting molding sib tsoo - - - - txias - ntim khoom kho cua sov
Qhov thib ob, qhov sib txawv ntawm kev siv
(1) Lub pob hlau carbon, lub pob hlau carbon siab, lub pob hlau bearing — tsheb kauj vab, bearing, pulley, slide rail, khoom siv tes ua, txee, lub pob thoob ntiaj teb, lub hnab nqa khoom, kho vajtse, kev sib tsoo
(2) Cov pob hlau tsis xeb - feem ntau yog siv rau kev tshem tawm thiab txhuam ntawm ntau yam khoom siv kho vajtse, yog li ntawd cov khoom ua haujlwm tuaj yeem ua tiav qhov du thiab ci ntsa iab: tooj liab, txhuas, nyiaj thiab lwm yam. Tsis tas li ntawd, cov pob hlau kuj tseem siv tau los zom cov khoom siv kho mob thiab cov khoom siv tshuaj lom neeg.
(3) Casting steel pob: zoo kub kub tsis kam, haum rau kev sib tsoo qhuav, feem ntau haum rau cov nroj tsuag cement
(4) Forged steel pob: muaj zog tiv taus corrosion, tsim nyog rau kev sib tsoo ntub, kev ua cov ntxhia thiab lwm yam forged pob yog qhov tsim nyog dua.
3. Kev sib piv ntawm kev casting thiab forging
(1) Hais txog kev hnav tsis kam, qhov nyuaj ntawm lub pob chromium siab (HRC≥60) tom qab quenching thiab tempering yog siab dua, uas yog ntau dua 2.5 npaug ntau dua li qhov hnav tsis kam ntawm lub pob hlau forged. Raws li kev sim tshawb fawb, kev noj ntawm tons ntawm cov pob raw ore ntawm cov pob forged yog ntau dua 2 npaug ntawm cov pob cam khwb cia.
(2) Lub pob chromium qis tsis zoo hnav tsis zoo, qhov nrawm nrawm siab, kev ua haujlwm pheej yig, thiab tsis pom zoo. Lub pob chromium siab muaj qhov nyuaj zoo thiab yog cov khoom siv zoo hnav tsis zoo, uas tau siv dav hauv cov chaw sib tsoo pob cement qhuav, tab sis lub zog ntawm lub pob chromium siab tsis zoo, thiab nws yooj yim tawg hauv lub chaw sib tsoo pob nrog txoj kab uas hla ntau dua 3 meters, thiab tus nqi siab.
