Cov khoom seem ntawm cov hlau ua tau zoo los ntawm cov haujlwm no?
Nyob rau hauv peb lub neej txhua hnub, qhov chaw ntawm cov hlau npluas yog qhov txhia chaw. Txhim kho qhov tsim nyog thiab qhov zoo ntawm peb cov neeg muas zaub, peb niaj hnub ua kom paub cov tshuab zoo los ntawm kev lag luam. Qhov zoo ntawm cov khoom siv hlau ntawm lub thwj cim yog pom hauv cov haujlwm. Tsom xam los ntawm cov ntsiab lus hauv qab no
1, tshuaj ntsuam tshuaj, kuaj hlau
Tshawb xyuas cov ntsiab lus ntawm cov tshuaj chemical hauv cov khoom, txiav txim siab txog qib thiab uniformity ntawm qhov loj ntawm cov khoom, ntsuas cov theem ntawm cov dawb cementite, banded qauv thiab non-metallic inclusions hauv cov khoom, thiab kos cov khoom rau shrinkage, porosity, thiab lwm yam teeb meem.
2, kev tshuaj xyuas
Cov thwj cim feem ntau yog ua los ntawm cov thawv kub los yog txias dua (raws li txias txias) cov ntawv hlau. Cov stamped yuav tsum muaj daim ntawv pov thawj zoo, uas yog xyuas kom meej tias cov ntaub ntawv ua tau raws li cov kev cai teev tseg. Thaum tsis muaj daim ntawv pov thawj zoo los yog lwm yam, cov khoom siv hlau ntawm cov hlau yuav xaiv cov khoom raw rau reinspection raws li xav tau.
3, kev sib tw ua tau zoo
Cov khoom siv raug ntxig cov kev xeem thiab khob ntsuas kev ntsuas los txiav txim cov khoom siv ua haujlwm hardening index n nqi thiab yas lim ratio r nqi. Tsis tas li ntawd, txoj kev sim rau kev tsim cov cuab yeej los ntawm cov ntawv hlau yuav tsum tau ua raws li cov lus qhia ntawm qhov tsim cov cuab yeej ntawm cov ntawv hlau thiab txoj kev sim.
4, kev kuaj tawv
Kev ntsuas ntawm cov hlau nplaum siv Rockwell hardness tester. Cov me me, qhov zoo li lub thwj cim yuav siv los kuaj cov phab ntsa uas tsis tuaj yeem ntsuas ntawm lub rooj zaum hauv Rockwell hardness tester.
5, lwm cov kev txwv ntawm kev ua haujlwm
Cov khoom siv hluav taws xob ntawm cov khoom siv thiab kev muaj peev xwm los koom nrog cov coatings, coatings, etc. yog ntsuas.
Cov txheej txheem ua rau kev txhim kho cov khoom hlau yog koom nrog txhua tus neeg. Nws tseem ceeb heev uas yuav tsum nco ntsoov tias qhov tseeb thiab qhov chaw ntawm lub thermal hlau stamping yog qhov tsawg tshaj li qhov ntawm cov hlau txias, tab sis nws tseem zoo tshaj qhov castings thiab forging qhov chaw, thiab txiav ua ntim tsawg.
