annealing
1. Lub hom phiaj: Thaum tshav kub kub ntawm cov hlau mus rau qhov kub thiab txias, khaws cia rau qee lub sijhawm, thiab tom qab ntawd maj mam txias nws los kho cov qauv crystalline, txo qhov hardness, thiab txhim kho kev ua haujlwm ntawm cov hlau hauv chav tsev kub.
2. Cov txheej txheem ua haujlwm:
Kev pub mis: Muab cov khoom ua tiav rau hauv lub qhov cub, ua tib zoo mloog lub qhov cub npog yuav tsum nruj nruj. Feem ntau, ib lub cub tawg tuaj yeem ua 7 yob (kwv yees li 1.2 tons / yob) tib lub sijhawm.
Tshav kub: Tsa qhov kub hauv qhov cub maj mam (txog 3-4 teev) mus rau qhov ntsuas kub.
Rwb thaiv tsev: 1018 thiab 1022 xov hlau raug khaws cia ntawm 680 degree -715 degree rau 4-6 teev, thiab 10B21, 1039, thiab CH38F cov xov hlau raug khaws cia ntawm 740 degree -760 degree rau 5.{{12 }}.5 teev.
Ua kom txias: Maj mam (txog 3-4 teev) txo qhov kub hauv qhov cub kom qis dua 550 degree , thiab tom qab ntawd txias rau chav sov nrog lub qhov cub.
3. Kev tswj xyuas zoo:
1. Hardness: cov khoom yog 1018, 1022 hlau, hardness yog HV120-170 tom qab annealing, thiab cov khoom yog nruab nrab carbon hlau, thiab hardness yog HV120-180 tom qab annealing.
2. Cov tsos mob: yuav tsum tsis muaj oxide zaj duab xis thiab decarburization ntawm qhov chaw.
