1. Rinsing tus kheej-drilling ntsia hlau yog qhov tseem ceeb thiab yuav tsum tau ua tib zoo saib xyuas, vim tias cov seem yuav nyob ntawm nws qhov chaw. Cov kauj ruam yaug no yuav tsum tau ua tom qab ntxuav nrog tus neeg saib xyuas silicate.
2. Kev stacking kom zoo yog qhov tseem ceeb thaum lub sij hawm tempering ntawm tus kheej-drilling ntsia hlau; txwv tsis pub, me ntsis oxidation yuav tshwm sim hauv cov roj quenching.
3. Cov tsos ntawm cov phosphide residue nyob rau saum npoo ntawm cov ntsia hlau muaj zog qhia tias tsis txaus siab rau kev nthuav dav thaum kuaj xyuas (point 1).
4. Blackening ntawm cov khoom nto vim yog tshuaj lom neeg cov tshuaj tiv thaiv qhia tias tsis tiav kev kho cua sov thiab tshem tawm tsis tiav ntawm alkaline residues. 5. Cov txheej txheem yuav xeb thaum yaug, thiab cov dej siv los yaug yuav tsum tau hloov ntau zaus.
6. Cov xeb ntau dhau qhia tias cov roj quenching tau siv ntev dhau lawm thiab yuav tsum tau hloov cov roj tshiab.
Tsau thauj tog rau nkoj bolts, tseem hu ua luv thauj tog rau nkoj bolts, yog cam khwb cia nrog lub hauv paus thiab siv los ruaj ntseg cov cuab yeej uas tsis muaj kev vibration muaj zog los yog cuam tshuam. 1. Tsau thauj tog rau nkoj bolts, tseem hu ua luv thauj tog rau nkoj bolts, yog cam khwb cia nrog lub hauv paus thiab siv los ruaj ntseg cov cuab yeej uas tsis muaj kev vibration muaj zog [...]
Cov ntsia hlau yog cov cuab yeej siv lub cev thiab kev ua lej ntawm cov qauv dav hlau inclined, kev sib hloov ntawm lub voj voog, thiab kev sib txhuam kom maj mam zawm cov khoom thiab cov khoom siv tshuab. Ib tug self-drilling ntsia hlau yog ib tug ntsia hlau nrog ib tug self-tapping laum ntsis ntawm nws lub ntsis. Screws yog ib qho kev tsim ntawm tib neeg thoob plaws hauv keeb kwm, thiab hais txog kev siv, lawv […]
