High Pressure Dej Phosphorus Tshem Tawm System

Hlau yog oxidized ntawm qhov kub thiab txias, tsim ib txheej tuab ntawm hlau oxide nplai (phosphorus nplai) ntawm nws qhov chaw. Yog tias cov txheej txheem ntawm cov hlau oxide no tsis tuaj yeem raug tshem tawm ua ntej dov, nws yuav raug nias rau hauv qhov chaw ntawm cov sawb los ntawm cov chais thaum lub sijhawm dov, cuam tshuam rau nws qhov zoo. Qhov seem hlau oxide nplai kuj tseem yuav ua rau kom hnav cov chais thiab txo cov kev pabcuam lub neej ntawm cov menyuam. Yog hais tias lub sawb yuav tsum tau pickled, cov seem hlau oxide nplai yuav ua rau kom nyuaj ntawm pickling thiab nce acid noj. Yog li ntawd, ua ntej dov lub billet, qhov saum npoo hlau oxide yuav tsum tau muab tshem tawm. Cov txheej txheem ntawm kev siv cov khoom siv hluav taws xob cuam tshuam ntawm cov dej kub siab kom tshem tawm cov hlau oxide nplai (high-pressure water dephosphorization) yog txoj kev siv ntau tshaj plaws thiab siv tau zoo.

Nyob rau hauv lub dephosphorization system, high-pressure dej generated los ntawm high-pressure dej twj tso kua mis nkag mus rau hauv lub dephosphorization nozzle. Nyob rau hauv qhov kev txiav txim ntawm lub nozzle, lub siab-siab dej tsim ib tug kiv cua-zoo li tus dej dav hlau nrog zoo heev quab yuam thiab tshuaj tsuag mus rau saum npoo ntawm billet (los yog nruab nrab billet). Nyob rau hauv qhov kev txiav txim ntawm lub siab-siab kiv cua-zoo li lub dav hlau dej, lub oxidized hlau nplai undergoes ib tug txheej txheem ntawm raug txiav, sai heev txias thiab shrunk, tev tawm ntawm lub hauv paus khoom, thiab ntxuav tawm ntawm qhov chaw ntawm lub billet (los yog nruab nrab billet. ), yog li tshem tawm oxidized hlau nplai.

Thaum cov dej kub siab raug ntaus rau ntawm qhov chaw ntawm steel billet los ntawm lub nozzle, cov kev hloov hauv qab no yuav tshwm sim:

a. Cov kiv cua zoo li lub ntsej muag tsim los ntawm cov dej ntws zoo li lub ntsej muag ntse, txiav cov ntawv hlau tuab thiab tsim cov kab nrib pleb. Nws tuaj yeem pom tias cov kiv cua nyias nyias muaj qhov cuam tshuam ntau dua;

b. Cov dej kub siab dhau los ntawm qhov tawg thiab ntsib cov khoom siv niam txiv kub siab, uas sai sai vaporizes thiab evaporates, tsim cov nyhuv zoo ib yam li qhov tawg, thiab cov ntawv oxidized hlau thiab cov khoom siv niam txiv sib cais;

c. Tom qab raug cuam tshuam los ntawm dej, oxidized hlau ntawv shrinks thaum nws txias, tsim ib tug lateral shear force, uas cais cov oxidized hlau ntawv thiab cov niam txiv cov ntaub ntawv.

d. Cov nyhuv dej ntws tawm ntawm lub dav hlau dej nrog rau pem hauv ntej qaij lub kaum sab xis ntws tawm ntawm cov ntawv hlau uas twb muaj lawm.

Cov txheej txheem tshem tawm phosphorus

Cov dej qhia tawm sab nraud yog cov dej huv huv, thiab cov dej zoo ua tau raws li qhov yuav tsum tau ua ntawm lub twj tso kua mis dephosphorization (qhov dej nkag siab yog {{0}}.25 ~ 0.30MPa). Cov dej nkag los ntawm sab nraud nkag mus rau hauv lub tank dej siab, thiab tom qab ntawd nkag mus rau hauv cov kav dej siab siab tom qab tau txais cov twj tso kua mis high-pressure dephosphorization. Vim cov ntaub ntawv sib txawv thiab dephosphorization degrees ntawm steel billets, tus nqi ntawm cov dej thiab siab xav tau rau dephosphorization ntawm steel billets kuj txawv. Txhawm rau kom ntseeg tau tias cov nyhuv dephosphorization ntawm steel billets, zaus converter yog siv los kho cov dephosphorization dej ntim thiab siab.

Cov yam ntxwv ntawm qhov system

Cov zis ntws ntawm lub twj tso kua mis hloov nrog cov khoom siv ntawm lub billet thiab lub dephosphorization ceev, thiab lub zog tso zis ntawm lub cev kuj hloov raws li. Kev khiav thiab siab yog kho los ntawm kev teeb tsa tus nqi ntawm lub siab transmitter. Kev ua haujlwm yog yooj yim thiab yooj yim, nrog rau qib siab ntawm automation thiab zoo zog txuag. Lub kaw lus muaj dej tsawg thiab kev siv hluav taws xob thiab cov nqi khiav haujlwm tsawg.

Cov Ntsiab Cai

Tom qab lub billet raug tshem tawm ntawm lub qhov cub cua sov, cov hlau oxide nplai npog nws qhov chaw txias sai heev, thiab cov hlau oxide nplai tsim nyob rau hauv lub cub tawg nthuav tawm cov kab nrib pleb. Nyob rau hauv cov tshuaj tsuag ntawm cov dej siab, qhov saum npoo ntawm cov hlau oxide nplai yog hauv zos txias, ua rau muaj kev sib cog lus loj, uas nthuav tawm cov kab nrib pleb ntawm cov hlau oxide nplai thiab qee qhov warps. Tom qab muaj kev cuam tshuam ntawm cov dej siab siab, qhov dynamic siab ntawm cov dej siab hauv qhov tawg ua rau lub siab zoo li qub ntawm cov kua dej thiab nkag mus rau hauv qab ntawm cov hlau oxide nplai, ua rau cov hlau oxide nplai tev tawm. qhov saum npoo ntawm billet, ua tiav lub hom phiaj ntawm kev tshem tawm cov hlau oxide nplai. Txhawm rau txhim kho qhov zoo ntawm cov hlau, nws yog ib qho tseem ceeb heev uas yuav tsum tau nruab ib lub tshuab nqus dej siab dephosphorization ntawm txoj kab dov. Lub cim ntawm kub dov hlau oxide nplai: ntawm qhov kub thiab txias, qhov chaw ntawm lub billet reacts nrog oxygen nyob rau hauv cov huab cua los tsim oxides. Ntawm cov oxides, ferrous oxide muaj cov pa oxygen qis tshaj plaws thiab yog nyob rau hauv txheej sab hauv ntawm oxide txheej, uas yog, txheej ze tshaj plaws rau hlau. Thaum qhov kub qis dua 570 degree, ferrous oxide nyob rau hauv lub xeev tsis ruaj khov. Cov ntsiab lus ntawm ferrous oxide nyob rau hauv lub teev nce nrog qhov nce ntawm qhov kub thiab txias ntawm steel billet. Thaum qhov kub ntawm cov hlau tshaj 700 degree, cov ntsiab lus ntawm ferrous oxide nyob rau hauv lub teev yog hais txog 95%. Piv nrog rau lwm cov ntsiab lus nyob rau hauv lub teev, ferrous oxide muaj ib tug qis melting point thiab feem ntau yuav yaj ntawm 1370 degree mus rau 1425 degree. Lub melting ntawm ferrous oxide txheej feem ntau accelerates tiam tus nqi ntawm lub teev thiab ua rau kom nkag mus rau hauv lub grain ciam teb, yog li ua rau cov teeb meem zoo ntawm cov hlau, nce zog noj, thiab txo cov yield zog ntawm cov hlau.

Tswj System

Thaum HMD pom qhov tuaj txog ntawm lub billet, nws yuav txuas ntxiv ib lub sijhawm (hloov raws li cov xwm txheej ntawm qhov chaw), kaw lub voj voog ncig, thiab ua kom lub siab ntawm cov raj xa dej siab. Lub inverter sai kho cov zis zaus kom tswj tau lub siab thiab ntws ntawm qhov system ntawm cov txheej txheem ua haujlwm.

Tom qab lub dephosphorization ntawm lub billet tiav lawm, lub voj valve qhib, lub kaw lus siab poob, thiab lub inverter yog hloov mus ua hauj lwm ntawm lub teeb zaus. Thaum lub sij hawm los ntawm kev ua tiav ntawm dephosphorization mus txog rau lub tom ntej no billet kuaj pom los ntawm HDM yog tsawg tshaj li ib tug tej yam nqi (adjustable), lub ncig valve yuav tsis qhib lawm, thiab lub kaw lus yuav tuav ib tug tej yam txaus txaus thiab siab.

Kev tswj tsis siv neeg ntawm cov dej kub siab dephosphorization feem ntau suav nrog kev tswj tsis siv neeg ntawm lub thawv dephosphorization thiab kev tswj tsis siv neeg ntawm cov twj tso kua mis siab.
