Lub sinter tsim los ntawm ib qho ntawm peb cov neeg siv khoom 'sinter tshuab tau tawg los ntawm ⑦1200 × 1600thee sizers. Lub crusher hniav yob kev sib hloov yog paub los ntawm kev sib kis ntawm cov iav pawg thiab phaj. Txij li cov hniav yob hnyav (qhov hnyav ntawm ob lub yob yog hais txog 25t), qhov kev sib hloov ceev kuj tseem ceev (74r / min rau kev kub ceev yob thiab 62.9r / min rau qis ceev yob), thiab lub zog ntawm sinter yog qhov siab, lub zog thiab qhov tseeb ntawm cov phaj txuas yog qhov xav tau. Thaum lub sijhawm tsim khoom, ob daim hlau sib txuas A thiab B tau tawg ntawm tib txoj haujlwm. Txij li thaum tsis muaj qhov seem los hloov lawv lub sijhawm ntawd, lawv xav tau kev kho sai sai. Txwv tsis pub, tag nrho lub Hoobkas yuav ntsib kev hem thawj ntawm kev ncua kev tsim khoom. Kev kho cov phaj txuas yuav tsum ua tau raws li cov hauv qab no: 1) qhov deformation me me, qhov nruab nrab ntawm qhov nruab nrab ntawm lub qhov taub qhov nruab nrab ntawm 75 thiab lub qhov taub ⑦80 yog 420 0.16 hli, thiab lub qhov ntawm qhov sib txuas ntawm phaj A thiab B yuav tsum yog concentric. Qhov no yuav tsum tau deformation ntawm lub phaj raws li 420mm ntev kev taw qhia yuav tsum me me, thiab tsis tuaj yeem tshwm sim pom tseeb distortion deformation, 2) lub zog ntawm qhov vuam yuav tsum sib npaug ntawm lub zog ntawm cov khoom siv hauv paus, txhawm rau ua kom tau raws li cov kev xav tau ntau lawm . 3) Cov kev ntxhov siab yuav tsum tau zam nyob rau hauv cov txheej txheem vuam kom deb li deb tau, thiaj li tsis txhob tawg dua hauv kev tsim khoom.
Qhov siab tshaj plaws thickness ntawmCoal sizers ntawm qhov chaw tawg yog 94mm thiab qhov ntev yog 180mm. Tsis tas li ntawd, qhov chaw tawg yuav tsum tau kho. Qhov no yuav ua rau kom qhov loj ntawm hexagram. Ntxiv mus, cov khoom ntawm cov phaj txuas yog ZG 270-500, thiab nws cov weldability tsis zoo. Yog hais tias lub hauv paus hlau yog melted ntau dhau lawm, nws yog ib qho yooj yim mus ua kom cov sulfur ntsiab nyob rau hauv weld thiab cuam tshuam lub weld zog. Raws li qhov xwm txheej saum toj no, peb tau txiav txim siab ua cov txheej txheem vuam tsim nyog thiab kev ntsuas los xyuas kom muaj kev kho kom zoo. 1) Kev npaj zawv zawg Ua ntej, txiav qhov tawg ntawm ob daim hlau txuas rau hauv ob npaug U-zoo li zawj raws li qhia hauv daim duab 2 nrog lub tshuab pa oxygen-acetylene. Tom qab ntawd, tshem tawm cov oxide txheej thiab lwm yam impurities ntawm qhov chaw ntawm lub hauv paus khoom nyob ze ntawm qhov zawj thiab qhov zawj nrog lub tshuab txiav thiab cov ntaub xuab zeb kom txog thaum cov hlau nplaum raug pom.
2) Vuam cov ntaub ntawv thiab cov khoom siv ⑦3.2mm thiab ⑦4.0mmE5016 electrode, cua sov kub yog 350 degree, tom qab 1 teev ntawm rwb thaiv tsev, khaws cia rau hauv daim ntawv rwb thaiv tsev, raws li siv nrog. Ac arc vuam tshuab yog siv rau vuam . 3) Lwm yam kev npaj (2) 75℃A.1OMmx120mm thiab ⑦80℃ow x 120mm steel pin txhua, spare, kho ntawm kev sib txuas phaj ib 4(1) Spot vuam txoj hauj lwm ntawm lub disconnected txuas phaj A ntawm lub tiaj steel phaj 1.5mm, nrog thickness yuav tsum tau 1.5mm. 1. Ces siv ⑦3.2mmE5016 electrode rau vuam hauv qab ntawm qhov zawj, (2) tshem tawm cov phaj sib koom ua ke A los ntawm cov hlau phaj, raws li qhov yuav tsum tau muaj ntawm daim duab 3 nyob rau hauv lub symmetrical sab ntawm lub phaj A ntxiv rau vuam 2 daim, xws li muaj zog reinforcement phaj, reinforcement phaj nthuav dav loj yog 400mm × 24mm Axide steel khoom: 300mm × 24mm Axide. nplaim taws kom sov rau thaj tsam zawj thiab nyob ze lub hauv paus hlau. Cov cua kub ntau yog li 160 hli ntawm ob sab ntawm qhov zawj. Thaum cov cua kub kub nce mus txog 150200C ( ntsuas nrog rab phom koob hmoov), qhov vuam pib.
(1) Vuam nrog ⑦4.0mmE5016 electrode. Vuam tam sim no yog 150-170A. Siv qeeb vuam, vuam pas nrig tsis viav vias, txhawm rau txo qhov nkag ntawm lub hauv paus hlau, tab sis yuav tsum xyuas kom meej tias lub hauv paus hlau nkag. Weld qhov zawj sib hloov los ntawm pem hauv ntej mus rau sab nraub qaum, thiab qhov sib txuas ntawm vuam yog qhia nyob rau hauv daim duab 1. Lub taub hau ntawm lub qhov rooj ntawm lub phaj phaj yog ces welded los ntaus cov vuam thiab cov hlau puag ncig kom tshem tawm cov kev ntxhov siab. (6) qhwv tag nrho workpiece nrog asbestos hlua tom qab vuam, qeeb txias. Thaum lub workpiece txias dhau los tuav, tshem tawm cov hlua asbestos, tshem tawm cov phaj ntxiv. (1) Txhim kho qhov sib txuas ntawm phaj B rau qhov kho qhov loj me ntawm phaj A los ntawm ob tus pins hlau thiab qhov chaw vuam. (2) nrog ⑦3.2mmE5016 electrode rau hauv qab ntawm qhov zawj vuam. Tshem tawm cov phaj sib txuas B thiab txuas cov phaj txhav ntawm ob sab ntawm daim phaj symmetrical. Cov txheej txheem vuam, qhov loj me, txoj hauj lwm thiab txoj kev ua kom txias qeeb ntawm cov phaj txuas ntxiv yog tib yam li kev kho phaj A. 1) Ultrasonic tshuaj xyuas tau ua tiav ntawm cov phaj txias A thiab B raws li, thiab tsis pom pom muaj qhov tsis zoo ntawm vuam tsis zoo . 2) Tsis muaj qhov txawv txav thiab nthuav dav deformation ntawm kev kho ob kab ntawv txuas nrog thawj, cov kev xav tau. 3) Cov txheej txheem kev teeb tsa yog du. Nws tau siv rau 3 xyoos thiab nyob rau hauv qhov zoo.
