Cov khoom siv nruab nrab ramming rau induction rauv

A. Kev npaj cov hlau crucible pwm: ua ntej ntxuav cov hlau crucible pwm, thiab txhuam ib txheej ntawm graphite hmoov sib npaug stirred nrog cav roj los yog dej nyob rau hauv ib puag ncig, thiab ces cia cov hlau crucible pwm cua qhuav lawm.

B. Induction furnace npaj: Qhov kub ntawm qhov cub induction yuav tsum tau qis qis kom qis dua 50 ua ntej kev tsim kho. Cov phab ntsa sab hauv ntawm lub coil mortar yuav tsum tau muab ntxuav, tsis muaj cov khoom seem lossis cov plua plav adhered, thiab tsis muaj dej txau rau ntawm phab ntsa sab hauv ntawm lub coil mortar.

C. Kev tsim kho

C1 rauv hauv qab kev tsim kho

C1.1 stirring ntawm nruab nrab ramming khoom: thawj zaug ntxuav lub tov khoom, pib lub sib tov lub cev muaj zog, ntxiv cov khoom siv hauv ob sab phlu (cov nyiaj ntxiv tsis pub tshaj 2/3 ntawm lub thawv tov khoom), ntxiv 4-5% kais dej thiab do, lub sij hawm sib tov yog 8-10 feeb. Cov Lus Qhia: Kev txiav txim siab ntawm kev ntxiv tus nqi: Muab cov khoom sib xyaw ntawm tes, nws tuaj yeem tsim ib pawg yam tsis tau xoob.

C1.2 Rauv hauv qab kev tsim kho: Thaum muab cov khoom siv hauv lub cub tawg sib npaug rau hauv lub qhov cub hauv qab, ntxiv 100mm tuab txhua lub sijhawm, siv cov kev vibration tiaj tus rau tamping cov khoom hauv qab, thiab tom qab ntawd roughen saum npoo, tom qab ntawd ntxiv 100mm tuab, thiab siv cov kev vibration tiaj tus. foob ​​hauv qab lub hnab. Cov khoom yog compacted, thiab lwm yam.

Rauv phab ntsa siv:

C2.1 Tom qab ua tiav qhov kev tsim kho ntawm lub qhov cub hauv qab, tso cov hlau crucible pwm rau hauv qhov cub induction. Thaum zaum cov pwm, xyuas kom meej tias qhov sib txawv ntawm cov hlau crucible pwm tsis glued thiab cov coils ntawm ob sab ntawm pwm yog tib yam.

C2.2 Tom qab ntawd ncuav cov khoom ramming rau hauv qhov sib txawv ntawm qhov cub induction. Thaum nchuav cov khoom, ncuav nws sib npaug ntawm cov haujlwm sib txawv ntawm sab phab ntsa, ntxiv qhov siab txog li 100 hli, thiab siv lub vibrator los rub ib ncig ntawm cov hlau crucible pwm. Lub hom phiaj yog ua kom cov khoom txaus txaus kom compact, thiab tib lub sij hawm pab txo cov khoom sib cais thaum lub sij hawm vibration ntawm cov hlau crucible pwm. Tom qab ntawd qhov saum npoo yog roughened, thiab qhov siab yog li 100 hli, thiab lub vibrator yog siv los rub ib ncig ntawm cov hlau crucible pwm, thiab lwm yam. Kev ceeb toom sov los ntawm Luoyang Quantong Kiln: Ua kom cov khoom siab C2.3 siab tshaj qhov siab ntawm coil cement thaum lub sij hawm tsim kho.

Hlau crucible pwm: rub cov hlau crucible pwm nrog lub crane, thiab ceev faj thaum kos cov pwm kom tsis txhob muaj kev puas tsuaj rau cov kab ua haujlwm.

Ci: qis-kub ci lub sij hawm: 2-4 teev, kub <300; nruab nrab-kub ci lub sij hawm: 6-8 teev, kub 300-800; Lub sijhawm ua haujlwm kub: 2-4 teev, kub 800-1000.
