Yuav Siv sijhawm ntev npaum li cas los tsim carbide rods?

Raws li cov chaw tsim khoom ntawm tungsten carbide rods, peb ib txwm tau txais ntau cov lus nug xws li, "Vim li cas nws siv sijhawm ntev los tsim cov pas nrig carbide?". Kab lus no yog muab cov lus teb rau koj, thiab peb yuav ua piv txwv ntawm kev tsim 200kg carbide puag ncig tuav.

Cov txheej txheem ntawm kev tsim cov tungsten carbide rods

A. Npaj cov khoom siv raw

Feem ntau, lub chaw yuav khoom yuav yuav thiab khaws cov khoom zoo tungsten carbide hmoov thiab binder hmoov.

B. Sib tov thiab ntub milling: 48 hnu

Tungsten carbide hmoov thiab binder hmoov yuav muab tov thiab milled nrog dej thiab ethanol nyob rau hauv lub pob milling tshuab. Txhawm rau milling lawv kom txaus thiab ua tiav cov qoob loo zoo tshaj plaws, lub pob milling tshuab yuav khaws milling li 2 hnub.

C. Txau kom qhuav: 24 teev

Tom qab ntub milling, tungsten carbide hmoov slurry drysnyob rau hauv ib tug tshuaj tsuag qhuav ntauwd rau 24 teev. Tsuas yog thaum cov tshuaj tsuag kom qhuav evaporates cov dej hauv tungsten carbide hmoov tuaj yeem nias thiab sintering tiav zoo dua.

D. Compacting: extrusion 228 teev; qhuav-lub hnab isostatic nias 36 hnu (suav nrog kev tso tawm sab hauv kev ntxhov siab thiab ziab)

Ob txoj kev tseem ceeb ntawmtsimyog extrusion thiab qhuav-lub hnab isostatic nias. Ob txoj kev no yuav raug nqi ntau lub sijhawm. Lub extrusion yuav raug nqi 12 teev rau compact, thiab qhuav-lub hnab isostatic nias yuav raug nqi 8 teev. Thaum lub sij hawm nias, tus neeg sawv cev tsim yog ntxiv thaum lub sij hawm extrusion, thaum lub hnab qhuav-isostatic nias tsis xav tau tus neeg sawv cev tsim.

Tom qab nias, cov rods compacted yuav tsum tso cov kev ntxhov siab sab hauv nyob rau hauv qhov kub thiab av noo ib puag ncig. Cov txheej txheem no tuaj yeem zam cov kab nrib pleb hauv cov txheej txheem hauv qab no. Tungsten carbide compacted rods yuav siv sij hawm ntev tso tawm sab hauv kev nyuaj siab, 144 teev rau extrusion, thiab 24 teev rau qhuav-bag isostatic nias. Tom qab ntawd tungsten carbide compacted rods, tom qab extrusion, yuav muab tso rau hauv qhov cub kom qhuav rau 73 teev, thiab cov pas nrig tom qab lub hnab qhuav isostatic nias rau 4 teev xwb.

Txawm hais tias lub hnab ntim qhuav isostatic nias yuav raug nqi tsawg dua lub sijhawm extrusion, nws tsuas yog siv tau rau kev tsim cov pas nrig loj nrog txoj kab uas hla ntau dua 16 hli.

E. Sintering: 24 teev

Tungsten carbide compacted pas nrig yuav sintered nyob rau hauv lub tshuab nqus tsev rauv. Cov txheej txheem no yuav kav ntev li 24 teev. Tom qab sintering, tungsten carbide qws blanks yuav tsum tau zom thiab tshuaj xyuas.

Txhawm rau ua kom tiav, cov txheej txheem tseem ceeb ntawm kev tsim 200kg tungsten carbide qws blanks yuav raug nqi txog 324 teev (13.5 hnub) rau extrusion thiab txog 132 teev (5.5 hnub) rau lub hnab qhuav isostatic nias, tsis hais lub sijhawm siv hauv kev sib tsoo thiab yog li ntawd.

Txawm li cas los xij, nrog cov khoom txaus txaus, koj tsis tas yuav txhawj xeeb txog lub sijhawm xa khoom. Peb tuaj yeem xa nws hauv 3 hnub. Yog tias koj txaus siab rau cov khoom lag luam tungsten carbide thiab xav paub ntau ntxiv thiab cov ntsiab lus, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa US MAIL hauv qab ntawm nplooj ntawv.
