Kev siv cov khoom siv hauv ob sab hauv ntawm lub qhov cub induction thiab cov txheej txheem ntawm kev tsim lub cub tawg

1. Dab tsi yog qhia ntawm no yog: Quartz acid qhuav rauv phab ntsa hauv ob sab phlu ramming khoom (acid furnace phab ntsa hauv ob sab phlu khoom). Cov khoom no yog pre-mixed qhuav ramming sib tov. Cov ntsiab lus ntawm binder, anti-cracking tus neeg saib xyuas thiab stabilizer tau npaj raws li qhov xav tau, thiab tus neeg siv tuaj yeem tso ncaj qha rau hauv kev siv. Kev saib xyuas tshwj xeeb: cov neeg siv tsis raug tso cai ntxiv cov ntaub ntawv thiab dej thaum siv. Cov khoom no yog tsim rau smelting grey hlau, dawb hlau, carbon steel, siab gong steel, siab chromium hlau, alloy steel, particle steel, ntxuav khoom, tooj liab, txhuas thiab lwm yam ntaub ntawv nyob rau hauv induction rauv.

2. Rauv lub tsev, qhov cub thiab sintering txheej txheem

Ua ntej qhuav-knotting lub qhov cub phab ntsa hauv ob sab phlu, ua ntej nteg ib txheej ntawm asbestos ntaub nyob rau hauv lub cub tawg txheej rwb thaiv tsev txheej, thiab manually theem thiab compact txhua txheej ntawm cov khoom thaum tso.

Knoted rauv taws hauv qab: lub thickness ntawm cov cua sov hauv qab yog li 200mm-thiab cov duab dhos ua ke hauv phab ntsa tom qab ci thiab sintering tsis tuab. Yog li ntawd, lub thickness ntawm pub yuav tsum nruj me ntsis tswj. Feem ntau, lub thickness ntawm cov xuab zeb filling yog tsis ntau tshaj 280mm / txhua lub sij hawm, thiab lub cub tawg phab ntsa yog tswj nyob rau hauv 100mm. Kev ua haujlwm ntau tus neeg tau muab faib ua kev hloov pauv, 60-4 tus neeg ua haujlwm ib zaug, 6 feeb hloov pauv txhua lub sijhawm knotting, nyob ib ncig ntawm lub qhov cub tig maj mam thiab siv sib npaug kom tsis txhob muaj qhov sib npaug.

Thaum cov pob caus nyob hauv qab ntawm lub cub tawg mus txog qhov siab xav tau, cov pwm crucible tuaj yeem muab tso los ntawm scraping nws tiaj tus. Hauv qhov no, kev saib xyuas yuav tsum tau saib xyuas kom ntseeg tau tias cov pwm crucible yog concentric nrog lub kauj, kho vertically nce thiab nqis, thiab cov duab yog ze li sai tau mus rau hauv qab ntawm lub cub tawg. Tom qab kho lub peripheral clearance kom sib npaug, siv peb cov ntoo wedges rau clamp, thiab nruab nrab hoisting hnyav yog nias rau kom tsis txhob lub cub tawg phab ntsa los ntawm tsoo. Kev tshem tawm ntawm quartz xuab zeb tshwm sim thaum knotting.

Knotting furnace phab ntsa: Lub thickness ntawm lub puab txheej ntawm lub cub tawg yog 90mm-120mm, ntxiv qhuav knotting khoom nyob rau hauv batch, daim ntaub yog uniform, lub thickness ntawm cov muab tub lim yog tsis ntau tshaj 60 hli, thiab knotting yog 15 feeb (phau ntawv knotting) kom txog thaum nws ntws tawm nrog lub ntug ntawm lub kauj. Lub crucible pwm tsis raug tshem tawm tom qab knotting tiav, thiab nws plays lub luag hauj lwm ntawm cov tshuaj tiv thaiv cua sov thaum ziab thiab sintering. Yog tias koj xav tshem tawm cov pwm pwm, qhwv cov phab ntsa sab nrauv ntawm cov pwm crucible nrog 2-3 txheej ntawm cov ntawv xov xwm ua ntej knotting phab ntsa rauv thiab qhwv nws nruj nreem nrog daim kab xev. Tom qab knotting, cov phab ntsa rauv yog rhuab mus txog 900 degrees, thiab cov ntawv xov xwm yog haus luam yeeb. Tshem tawm lub crucible pwm sai sai. Lub thoob hlau nrog txoj kab uas hla ntawm 10-15 cm thiab qhov siab ntawm lub qhov cub lub qhov ncauj yog tiaj tus thiab tus pin hlau yog siv rau cov tshuaj tiv thaiv cua sov thaum ziab thiab sintering.

Ci thiab sintering specifications: thiaj li yuav tau txais peb-txheej txheej txheem ntawm lub cub tawg nyob rau hauv ob sab phlu, lub ci thiab sintering txheej txheem yog kwv yees muab faib ua peb theem: xyuam xim rau cov hlau pin thiab me me hlau ntxiv nyob rau hauv lub cub tawg thaum lub sij hawm ci thiab sintering. Tsis txhob ntxiv cov hlau loj, taw tes lossis toothed hlau.

Kauj Ruam 900: Ua kom sov cov pwm pwm rau 20 ° C rau 200 feeb ntawm tus nqi ntawm 20 tshav kub preservation rau 300 feeb, 20 kub preservation rau 400 feeb, thiab 20 kub preservation rau XNUMX feeb. Lub hom phiaj yog kom tshem tawm tag nrho cov dej noo nyob rau hauv lub qhov cub phab ntsa hauv ob sab phlu.

Semi-sintering theem: Khaws qhov kub ntawm 400 rau 20 feeb, 500 rau 20 feeb, thiab 600 rau 20 feeb. Cov cua kub yuav tsum tau tswj kom tsis txhob tawg.

Ua tiav sintering theem: kub sintering, sintered qauv ntawm lub crucible yog lub hauv paus rau kev txhim kho nws cov kev pab cuam lub neej. Lub sintering kub yog txawv, lub thickness ntawm sintering txheej yog tsis txaus, thiab cov kev pab cuam lub neej yog ho txo.

Nyob rau hauv 2T induction rauv, txog 950 kilograms ntawm cov hlau pins yog ntxiv los txhim kho cov cua sov ntawm lub kauj thaum lub sij hawm ci txheej txheem. Raws li qhov ci thiab sintering txuas ntxiv mus, lub zog hluav taws xob uas ruaj khov yog tsim los ntawm kev xa hluav taws xob qis kom do cov hlau molten kom puv lub cub tawg. Qhov kub ntawm lub cub tawg yog nce mus rau 1700 degrees kom qhov kub thiab txias rau 60 feeb, kom lub puab txheej ntawm lub cub tawg yog rhuab sib npaug zos rau thiab down. nruj me ntsis tswj qhov kub ntawm peb theem hloov chaw ntawm quartz xuab zeb, txhawb tag nrho cov theem hloov ntawm quartz xuab zeb, thiab txhim kho thawj sintering zog ntawm lub cub tawg hauv ob sab phlu.

3. Ntsiab lus

Rau lub neej ntawm lub cub tawg phab ntsa hauv ob sab phlu ntawm lub qhov cub induction, ntxiv rau kev ua kom tiav thiab tsim nyog peb-txheej rauv phab ntsa hauv ob sab phlu, kuj yuav tsum tau them nyiaj rau kev ua haujlwm li niaj zaus. Kev tshawb fawb ci thiab sintering cov qauv, kev ua haujlwm nruj, tuaj yeem txuas lub neej ntawm lub cub tawg.

4. Cov txheej txheem ntim thiab khaws cia

Multi-layer noo noo-pov thawj daim ntawv thiab ntim zaj duab xis 25kg / hnab, khaws cia rau hauv qhov chaw qhuav kom tsis txhob ya raws. Cov lus pom zoo ntawm txee lub neej yog qhov zoo heev
