Nyob rau hauv qhov chaw uas muaj cov chaw ua cement ntau, cov tshuab nqa thoob tsis yog tsuas yog siv cov saw hlau uas ruaj khov xwb tab sis kuj siv cov khoom sib txuas tseem ceeb uas ua lub luag haujlwm tseem ceeb ntawm cov saw hlau thiab cov thoob. Cov khoom sib txuas no, feem ntau ua raws li DIN 745 thiab DIN 5699 tus qauv, yog cov choj uas hloov cov zog nqa los ntawm cov saw hlau mus rau cov thoob uas nqa cov khoom siv abrasive xws li clinker, limestone, thiab cov hmoov nplej nyoos.
Cov thawj coj hauv kev lag luam xws li RUD, CICSA, thiab Heko tau tshwj xeeb hauv cov khoom siv no ntev heev, siv cov txheej txheem metallurgy thiab cov txheej txheem kho cua sov kom ntev lub neej kev pabcuam hauv qab cov xwm txheej nyuaj tshaj plaws.
Cov Qauv Tsim thiab Cov Ntawv Thov Txheem
Ob lub qauv txuas tseem ceeb yog cov uas tswj hwm kev lag luam cement:
- DIN 745 shacklesmuaj lub cev ua los ntawm U-hom nrog lub phaj nrug thiab lub txiv ntoo sib dhos, tsim los rau cov tshuab nqa khoom siv dav dav, cov khoom siv thauj khoom siab. Cov khoom sib txuas no txuas ncaj qha rau cov thoob rau cov xov hlau.
- DIN 5699 cov hlua khimuab cov qauv tiaj tus thiab cov qauv me me, muaj cov xov ntev dua uas tso cai rau cov phaj nrug kom haum ntawm lub thoob thiab cov saw. Qhov kev tsim no muab kev nyab xeeb zoo dua rau kev ua haujlwm thiab txhim kho kev tawg thiab kev qaug zog piv rau DIN 745, ua rau lawv haum rau qhov sib nrug ntawm lub thoob thiab txo qhov sib txawv ntawm lub voj voog (PCD) elevators.
Ob qho qauv no tau tsim los ua haujlwm seamlessly nrog cov saw hlau uas ua raws li DIN 764 thiab DIN 766.
Kev Xaiv Khoom Siv thiab Txheej Txheem Forging
Tsis zoo li kawcov saw hlau txuas puag ncig, cov khoom sib txuasmuaj ib qho qauv qhib nrog ib lub pin hla uas tshem tau, tsim kom muaj qhov chaw ntxhov siab. Txhawm rau them rau qhov no, cov khoom sib txuas zoo yog tsim los ntawm kev siv cov hlau sib xyaw ua ke zoo. Cov ntaub ntawv siv feem ntau suav nrog 45 # hlau kho cua sov, Cr-Mo (chromium-molybdenum) alloys, thiab Cr-Ni-Mo (chromium-nickel-molybdenum) alloy steels. Qib txuas uas xav tau txiav txim siab qhov kev xaiv hlau sib xyaw tshwj xeeb. Kev sib xyaw ua ke ua rau cov noob nplej sib phim nrog cov duab ntawm lub txuas, ua rau muaj kev tiv thaiv kev qaug zog ntau dua nyob rau hauv qhov kev sib txuas tas mus li thiab kev cuam tshuam uas ntsib hauv kev ua haujlwm ntawm cov cement.
Kev Kho Kom Ruaj Kho thiab Kev Tswj Xyuas Zoo
Yuav kom ntseeg tau tias cov khoom sib txuas ua tiav qhov kev tiv taus hnav piv rau cov txuas puag ncig carburized, cov chaw tsim khoom lag luam ua lag luam siv cov kev kho mob tshwj xeeb hauv zos ntawm cov ntsiab lus sib txuas ntawm kev sib cuag nrog cov saw hlau. Cov no tuaj yeem faib ua:
- Cov khoom sib txuas uas tau ua kom tawv / ua kom tawv los ntawm kev siv induction: Ua kom tawv txog li ntawm 950–1100 N/mm², nrog rau kev ua kom tawv ntawm cov ntsiab lus sib txuas ua kom tawv ntawm qhov chaw tsawg kawg yog 600 HV1 (55HRC).
- Cov khoom sib txuas uas tawv / carburized: Rau cov ntawv thov abrasive hnyav tshaj plaws, cov chaw tsim khoom xws li Pewag muab cov carburizing ntxiv, ua tiav qhov nyuaj ntawm 750 HV1 lossis siab dua ntawm thaj chaw sib txuas.
Cov kev tswj xyuas zoo tseem ceeb uas cov chaw tsim khoom loj tau teev tseg suav nrog qhov tob ntawm qhov tawv (≥0.1 × d), qhov tawv ntawm qhov chaw (yam tsawg kawg nkaus 600–750 HV1), thiab lub zog pov thawj thiab lub zog tawg sib npaug lossis ntau dua li cov saw hlau loj tshaj plaws uas lawv tau sib phim. Kev sim ua tib zoo ntawm qhov zoo ntawm qhov chaw thiab cov kev kho cua sov ua kom ntseeg tau tias muaj kev tiv taus qaug zog thoob plaws txhua pawg ntau lawm.
Kev Cov Teeb Meem Ua Haujlwm thiab Kev Hloov Chaw
Txawm hais tias cov khoom sib txuas tau raug forged thiab xaiv cov khoom tawv kom ze rau lub zog ntawm cov txuas puag ncig, lawv tseem yog qhov tsis muaj zog tshaj plaws ntawm lub kaw lus vim lawv qhov geometry qhib thiab cov xov fasteners. Lub cheeb tsam sib txuas ntawm lub connector thiab cov saw hlau yog ib qho ntawm cov chaw ntxhov siab tshaj plaws hauv tag nrho lub tshuab nqa, ua rau nws yooj yim hnav, qaug zog tawg, thiab xoob ntawm cov txiv ntoo nyob rau hauv kev co tas li.
Cov hom kev ua tsis tiav feem ntau muaj xws li:
- Kev hnav ntawm qhov chaw: Kev puas tsuaj ntawm cov ntsiab lus sib txuas, txo qhov chaw hla-sectional zoo
- Kev tawg ntawm lub zog: Kev ntxhov siab cyclic pib cov kab nrib pleb ntawm cov ntsiab lus ntawm kev ntxhov siab, uas nthuav dav mus txog thaum tawg
- Kev xoob cov ntsia hlau: Kev xoob cov txiv ntoo los ntawm kev co, feem ntau txo los ntawm cov txiv ntoo uas xauv nws tus kheej lossis cov ntaub thaiv caij nplooj ntoos hlav
Yuav kom txo tau cov kev pheej hmoo no, cov xov sib txuas yuav tsum tau ruaj ntseg nrog cov txheej txheem thaiv kom tsim nyog, thiab cov phaj nrug yuav tsum tau teeb tsa kom raug. Kev siv cov khoom sib dhos uas xauv nws tus kheej thiab peb tiv taus kev co tas li thiab cov voj voog kub yog cov yam ntxwv tsim qauv tseem ceeb rau kev siv lub neej ntev.
Kev paub txog kev lag luam qhia tau hais tias txawm hais tias cov saw hlau nws tus kheej yuav muaj lub neej ua haujlwm ntsuas hauv pua pua txhiab tons xa mus, cov khoom siv thoob thiab cov khoom sib txuas yuav xav tau hloov pauv sai dua. Qee cov ntaub ntawv hauv daim teb qhia tau hais tias cov khoom siv thoob yuav xav tau hloov pauv tom qab kwv yees li 400,000 tonnes ntawm cov khoom siv, uas sawv cev rau lub sijhawm muaj txiaj ntsig rau cov nroj tsuag los npaj kev saib xyuas tiv thaiv thiab txo qhov kev pheej hmoo ntawm lub sijhawm tsis ua haujlwm uas tsis tau npaj tseg.
Cov khoom siv sib txuas ntawm cov saw hlau puag ncigyog cov kev tsim kho tshiab uas tsim los kom muaj kev sib haum xeeb - qhib rau hauv kev tsim tab sis yuav tsum tau tiv taus tib yam kev sib txhuam hnyav, kev thauj khoom dynamic, thiab cov chaw abrasive zoo li cov txuas kaw uas lawv koom nrog. Los ntawm kev ua kom raug, kev xaiv cov khoom siv zoo tshaj plaws, thiab kev xaiv cov ntaub ntawv tawv (carburizing) ntawm cov ntsiab lus sib txuas, cov chaw tsim khoom ua ntej xws li RUD, CICSA, thiab Heko tsim cov khoom sib txuas uas xa cov kev ua tau zoo txhim khu kev qha nyob rau hauv qhov cuam tshuam siab, kev ua haujlwm tas mus li ntawm cov tshuab nqa cov thoob cement. Kev tshuaj xyuas tsis tu ncua rau kev hnav ntawm thaj chaw sib txuas, kev txheeb xyuas kev ruaj ntseg ntawm cov khoom siv txuas, thiab kev hloov pauv raws sijhawm raws li tonnage xa khoom yog cov kev coj ua tseem ceeb los tiv thaiv kev ua tsis tiav loj heev thiab ua kom lub sijhawm ua haujlwm siab tshaj plaws.
