Txiav hlau → khoov txias → sib koom ua ke → vuam → calibration thawj zaug → kho cua sov → calibration thib ob (pov thawj) → tshuaj xyuas. Vuam thiab kho cua sov yog cov txheej txheem tseem ceeb hauv kev tsim cov hlau txuas ncig mining, uas cuam tshuam ncaj qha rau qhov zoo ntawm cov khoom. Cov txheej txheem vuam tshawb fawb tuaj yeem txhim kho cov txiaj ntsig thiab txo cov nqi tsim khoom; cov txheej txheem kho cua sov tsim nyog tuaj yeem ua si tag nrho rau cov khoom siv thiab txhim kho qhov zoo ntawm cov khoom.
Yuav kom paub tseeb tias qhov vuam zoo ntawm cov hlau txuas hlau hauv kev khawb av, kev vuam tes thiab kev vuam taub qab tsis kam tau raug tshem tawm. Kev vuam taub qab siv tau dav vim nws qib siab ntawm kev ua haujlwm tsis siv neeg, kev siv zog tsawg, cov khoom zoo ruaj khov thiab lwm yam zoo heev.
Tam sim no, txoj kev kub hnyiab thiab tempering nruab nrab feem ntau siv rau hauv kev kho cua sov ntawm cov hlau txuas hlau. Lub ntsiab lus ntawm kev kub hnyiab thiab tempering nruab nrab yog tias cov qauv molecular ntawm ib yam khoom raug do hauv qab lub zog hluav taws xob, thiab cov molecule tau txais lub zog thiab sib tsoo los tsim cua sov. Thaum kev kho cua sov thiab tempering nruab nrab, lub inductor txuas nrog lub zog hluav taws xob nruab nrab ntawm qee zaus, thiab lub workpiece txav mus rau qhov ceev sib xws hauv lub sensor, yog li ntawd lub zog hluav taws xob nrog tib zaus thiab kev taw qhia rov qab yuav tsim nyob rau hauv lub workpiece, uas yuav hloov lub zog hluav taws xob mus rau hauv lub zog cua sov, thiab lub workpiece yuav raug cua sov rau qhov kub uas xav tau los ntawm kev quenching thiab tempering hauv lub sijhawm luv luv.
Qhov cua sov induction nruab nrab muaj qhov zoo ntawm kev kub ceev, tsawg dua oxidation, cov qauv quenching zoo thiab austenite noob loj tom qab quenching, uas txhim kho lub zog thiab toughness ntawm cov saw txuas. Tib lub sijhawm, nws kuj muaj qhov zoo ntawm kev huv, yooj yim kho thiab kev ua haujlwm siab. Hauv theem tempering, qhov kub tempering siab hauv thaj chaw vuam saw txuas tuaj yeem tshem tawm qhov kev ntxhov siab sab hauv quenching hauv lub sijhawm luv luv, uas muaj qhov cuam tshuam loj heev rau kev txhim kho qhov plasticity thiab toughness ntawm thaj chaw vuam saw txuas thiab ncua qhov pib thiab kev loj hlob ntawm cov kab nrib pleb. Qhov kub tempering ntawm sab saum toj ntawm lub xub pwg nyom qis dua, thiab qhov nyuaj dua tom qab tempering, uas yog qhov zoo rau kev hnav ntawm cov saw txuas hauv cov txheej txheem ntawm kev ua haujlwm thiab tawm tsam lub pob khawm ntawm cov saw txuas thiab lub sprocket meshing.
