Alloy Steel Hlau kos cov kev cai
Cov ntsiab lus carbon ntau dua 0.6% ntawm pob khawm siab zog thiab siab zog Alloy hlau hlau, nws cov khoom kho tshuab thiab cov txheej txheem yuav tsum muaj tsawg, nruab nrab carbon hlau alloy hlau yog txawv ntawm qhov khoom tiav tshuaj xyuas feem ntau tshwm sim tsis zoo. Ntxiv rau kab siab, qhov tsis zoo, tsis meej thiab tsis meej pem, thiab lwm yam, vim yog tsis muaj zog los yog ntau lub zog (tsis muaj teeb meem tsis sib haum), los yog hauv torsion kuaj plaub thorns (torsion) Crack), pob txha tsis ncaj. Tshwj xeeb tshaj yog Pawg II los yog ntau tshaj li High-Force Alloy Steel Wire uas yuav tsum tau muaj dua, yog li yuav tsum muaj kev lag luam heev.
1. Yuav tsum tau ua raws li cov txheej txheem dhau los
(1) xaim hlau loj tshaj plaws ntawm cov hlau qag hlau, tsis tsuas yog yuav tsum muaj qhov zoo txaus (tshwj xeeb tshaj yog, yuav tsum tsis txhob folding), tab sis kuj xav kom cov ntsiab lus carbon, tshuaj muaj pes tsawg leeg, muaj quas kev, qhov tob tob thiab qhov tob thiab nyob rau hauv txoj kab nrog cov kev cai. Xaiv ntawm cov kab hlau yuav tsum yog tuab tuab, yog li ntawd muaj cov sijhawm txaus duab. Nquag txaus los kos qhov khoom tiav, nws qhov chaw zoo thiab thim rov qab yog feem ntau tsis zoo.
(2) kev kho cua sov Kev kho cua sov yog lub hauv paus ntawm High-strength Alloy Steel Hlau, xaim daim duab ua ntej yuav mus dhau normalizing, los txhim kho nws lub koom haum. Tom qab quenching cov kev kho mob nkhaus, qhov tseem ceeb yog lub uniformity ntawm cov cua sov thiab kub taub hau. Thaum tshav kub kub kho tsis haum, ntau tshaj yog qhov ntsuas kub tsis sib xws, muaj zog hloov mus rau hauv lub zog, thiab tshwm sim ntawm kev ferrite dawb thiab ntxiv rau. Ntawm T9A. Xws li Alloy Steel Hlau, tab sis kuj los tiv thaiv kom txhob muaj cov kabmob. Yog li, peb yuav tsum nruj nruj siv cov txheej txheem kev ua haujlwm, ua tib zoo kuaj, thiab ua kom qis qis dua.
(3) pickling lubrication alloy hlau ntsa yog qhov seem oxide, nyob rau hauv lub tho qhov kev kuaj yuav tshwm sim thaum cov kab tawg. Li ntawd pickling los xyuas kom huv. Qhov saum npoo yuav ua tau ntau heev ntawm kev siv ntawm acid pickling, thiab pickling nyob rau hauv lub tiav lawm ua ntej thawj mechanical xeb.
Cov hluav taws lubrication feem ntau yog siv cov kab ua ntej coated ua lime, los yog xeb hauv lub pwm lub thawv hauv calcium thiab cov hmoov nchuav, thiab tsis txhob siv cov phosphate txheej. Kev siv phosphating txheej nyob rau hauv cov hmoov txhuas hniav kom yooj yim ntsaws lub tshuab ua hluav taws xob (hluav taws xob tiv thaiv cov cua sov uas tsis cuam tshuam dab tsi), thiab yuav ua rau cov hlau lead dai. Tab sis ua ntej tiav cov khoom thiab lub me specifications ntawm semi-tiav lawm khoom siv tau siv phosphate txheej. Lub thickness ntawm phosphating zaj duab xis ua ntej cov khoom tiav tas yuav tsum me ntsis loj kom paub tseeb tias ntau dua 8 zaug ntawm daim duab. Phosphating txheej ntawm qhov zoo thiab cov tuab ntawm cov hlau txhuam cov hlau sib tw tag lawm yog ib qho kev txhim kho rau cov yeeb yaj kiab zoo phomphate ua rau cov hlau txhim kho hlau rhuav tshem ntau dua.
2. Cov uas yuav tsum tau kos duab
(1) xaiv xaim hlau tshuab Alloy Steel Hlau yuav tsum tsis muaj twisting ntawm lub rub, yog li cov pulley hlau drawing tshuab tsis haum rau cov zus ntawm no tiav Alloy hlau hlau. Kev siv cov khoom zoo li no yuav cuam tshuam txog kev qaug zog ntawm Alloy Steel Wire (torsion test). Nyob rau hauv lub dhau los qhuav, lub coarse specifications ntawm high zog tagnrho Alloy Steel Hlau, feem ntau siv ib zaug xwb hlau drawing tshuab. Qhov zoo ntawm hlau alloy steel kos nrog nws yog zoo, tab sis qhov tawm los yog tsawg thiab txoj haujlwm khwv kuj tseem loj. Tam sim no, lub tshuab linear drawing tau maj mam nce, nws yuav raug kho nyob rau hauv ib qho ntau yam kom tau ib feem ntawm cov nqi nias ceev, kom tau raws li cov specifications ntawm Alloy Steel Hlau kev kos duab thiab cov khoom tsim nyog zoo. Tab sis cov khoom siv no kim heev, hluav taws xob muaj txoj hauv kev, hauv kev kub ceev yog tseem txaus kom txias. Thiab lub lag luam yuav tsum muaj qee yam ntawm kev siv tshuab.
Muaj tseem muaj dej tank loj lub cav, tab sis kuj haum rau cov duab hauv cov ntxhib specifications ntawm siab zog Alloy Steel hlau, khoom zoo, siab yield. Qhov tsis zoo yog tias cov duab kos cov kab nrig sib xyaw hlau muaj ntau dua kev ua haujlwm thiab tsis tuaj yeem kho qhov sib txuam sib nrauj kom yooj yim. Raws li rau qhov zoo loj Alloy Steel Wire, feem ntau ntawm kev siv dej me me lub teeb duab teeb duab.
(2) cua txias yuav tsum muaj siab muaj zog hlau tho cua sov yog siab heev, yog tias tsis yog: kev siv cov cua txias, nws yuav ua rau 300 ~ 500 degrees siab, tsis tsuas yog yuav ua rau lub ciav dej coking, thiab yuav ua rau hloov Alloy Steel Hlau qauv, Yog li ntawd mechanical zog poob. Yog li, nws yuav tsum tau txo qhov ntsuas kub ntawm cov hlau xov tooj cua hauv qab 1500 ° C.
(3) nyob tsis muaj zog Muaj zog hlau Alloy Steel Hlau nyob rau hauv cov txheej txheem teeb duab, yog qhov chaw khiav hauj lwm me ntsis deviated, uas tej zaum yuav tshwm ntsej muag thiab tawg, uas yog tagnrho hlau hlau tsis tau tso cai rau tshwm sim. Li ntawd kom nruj me ntsis kho qhov chaw ntawm lub mold box, thiab them sai sai rau lub uniform kub kho.
(4) ib feem ntawm cov nqi quab yuam vim muaj zog muaj zog hlau xiam oob khab deformation, yog tias qhov feem ntau nce nqi nce, nws yuav ua rau tsis sib txig deformation, ua rau muaj torsional tawg. Yog li ntawd, qhov siab dua cov ntsiab lus carbon ntawm Alloy Steel Hlau, qhov me me ntawm lub siab tus nqi shrinkage.
(5) Daim duab nrawm Cov kev sib zog ntawm cov hlau uas sib xyaw kub yog kub heev, nws tsis haum rau high-speed qhuav rub, los xyuas kom zoo dua rov qab. General qhuav rub khiav ntawm 60 mus txog 150 m / min.
(6) pwm thiab lubrication pwm mus ncig, smoothness kom siab, thiaj li txo cov cua sov, cov pwm ntawm lub khob khoob yuav tsum yog cov ntsiab lus me. Phosphating txheej ntawm cov kev cai zoo ntawm kev nplua, khoom tawv thiab ib co thickness, lub peev xwm mus rub ntau zaus. Yuav kom txhim kho lub lubrication nyhuv ntawm phosphating txheej, pwm lub thawv tuaj yeem muab xab npum calcium
