Ua kom muaj kev sib txhuam ntawm cov crusher rau cov menyuam thiab cov seem seem thiab nthuav lub kaum sab xis ntawm lub puab tsaig crushing tuaj yeem ua rau cov pob seem seem nrog cov kab uas hla loj dua nkag mus thiab zom.Yog li ntawd, cov vuam flakes nrog qhov dav ntawm 30 hli thiab qhov siab ntawm 10 hli tau muab tso rau ntawm qhov sib nrug ntawm 100 hli ntawm qhov chaw ntawm lub teeb rau cov menyuam.Tom qab cov seem seem nkag mus rau hauv lub crushing chamber, nws yog txiav nyob rau hauv qhov kev txiav txim ntawm tus hniav nto, thiab lub kaum sab xis ntawm lub puab tsaig crushing yog nce, thiab qhov nruab nrab grain yuav tau.Txoj kab uas hla (6070mm) yog qhov loj thiab cov seem seem tawg.
Lub vuam cov menyuam nto yog tsim los ntawm phau ntawv arc vuam, thiab qhov chaw ntawm ob-cov menyuam crusher yog surfacing.Cov ntsiab lus tseem ceeb ntawm surfacing yog raws li nram no.
(1) D-65, D-667 thiab 506 vuam rods raug xaiv.Ua ntej vuam, raws li cov lus qhia rau vuam rods, vuam rods yog qhuav thiab muab tso rau hauv lub incubator siv.
(2) Ntxuav txheej qaug zog ntawm cov menyuam nto, ntxuav nws nrog cov pa roj carbon arc gouging, thiab npaj cov txheej txheem qaug zog ntawm cov menyuam yaus kom nthuav tawm cov menyuam mus rau cov txheej txheem txheej txheem.
(3) Siv lub tshuab DC welding, uas yuav tsum tau thim rov qab (lub vuam pas nrig txuas nrog qhov zoo electrode).Thaum surfacing, AC vuam tshuab yuav tsum tsis muaj-load voltage ntawm 70V, thiab tam sim no yog tswj ntawm txog 200A.Yog tias tsis muaj qhov hluav taws xob qis dua 70V, qhov tam sim no yuav tsum tau nce ntxiv, uas yog raws li kev sib xyaw ua ke ntawm cov electrode thiab lub hauv paus hlau.Qhov piv ntawm qhov dav ntawm cov hlaws weld rau qhov siab yog qhov zoo dua 31.
(4) Tom qab preheating lub yob nto, ua ntej siv 506 electrode (alkaline electrode, haum rau vuam 16M khoom, pheej yig, thiab zoo sib raug zoo nrog lub hauv paus hlau) rau weld 13 txheej ntawm carbon steel, thiab puag ncig lub yob.Tom qab ntawd sib npaug ntawm ob peb txheej ntawm D-667 (high-chromium cam khwb cia hlau surfacing pas nrig tuaj yeem tiv taus siab thiab hnav tsis kam, hardness HRC48 tom qab vuam, hnav tsis kam, corrosion kuj thiab cavitation kuj qis dua 500 siab kub) Yuav tsum muaj tuab.Tom qab D-667 weld txheej yog surfacing, ib txheej ntawm D-65 (high-alloy surfacing pas nrig Cr-Si-Mo-B high-corrosion cam khwb cia-hlau hnav-resistant nto hnav-resistant electrode yuav surfacing. Tsis tshua muaj kev cuam tshuam.Resistant rau muaj zog abrasive hnav, qhov zoo ntawm cov electrode no zoo surfacing, tsis muaj slag tom qab vuam, siab hnav tsis kam, hardness tom qab vuam HRC60. Txhim kho hnav lub neej 310 zaug), thickness ntawm surfacing yog 35mm.Hnav txheej Lub thickness kev nyuab siab yog sib xws kom cov squeezing roller tseem ncig thaum siv.
3 Kev xaus
Los ntawm kev xyaum ntau lawm, qhov nruab nrab ntawm qhov loj me ntawm cov seem electrode ntawm lub crusher yog nce los ntawm 40mm mus rau 60mm thaum lub sij hawm tsim, uas txo cov khoom load ntawm cov khoom siv ntws, txhim kho kev yoog rau cov menyuam crusher, thiab kev pabcuam lub neej. cov menyuam crusher nce mus txog 10 Lub hli, cov ncej tawg tau tag nrho 50,000 tons.
