Kev ua tau zoo yuav tsum tau rau thoob cov hniav thiab hooks ntawm excavators
Apr 20, 2022
Hauv kev pabcuam nquag, lub thoob cov hniav ntawm excavator tsis tsuas yog raug kev puas tsuaj rau lub cev, tab sis kuj muaj qee yam cuam tshuam. Yog li ntawd, cov txheej txheem saum npoo ntawm qhov zoo tshaj plaws thoob cov hniav raw cov ntaub ntawv ntawm excavator yuav tsum muaj lub zog siab thiab hnav tsis kam, thiab cov khoom siv pa yuav tsum muaj zog compressive thiab ductility, uas tsis tuaj yeem dhau los ntawm ib qho khoom siv raw. Niaj hnub no, tus yuam sij ntawm thoob cov hniav hauv Suav teb yog ua los ntawm cov hlau manganese siab, uas tseem ua tau zoo ntawm cov hlau. Nws feem ntau ntseeg tias txheej txheej ntawm cov hlau manganese siab tuaj yeem ua rau cov txheej txheem txias ua haujlwm tsuas yog nyob rau hauv cov qauv kev puas tsuaj ntawm kev cuam tshuam los yog muaj zog chiseling. Lub ntsiab zoo thoob khib nyiab factories ntawm excavator thoob hniav manufacturers qhia siab hnav tsis kam, txwv tsis pub lub thoob hnav-resistant thoob nuv factories tsis tuaj yeem khaws nrog kev hnav tsis kam ntawm cov hlau dav dav. Daim duab 1 qhia tau hais tias qhov txias ua hauj lwm hardening nkhaus ntawm lub thoob hniav tip txoj hauj lwm ntawm 2m3 excavator thiab lub thoob cov hniav tip txoj hauj lwm ntawm thoob log excavator. Nws tuaj yeem pom los ntawm qhov nkhaus hauv daim duab uas lub zog txias hardening ntawm lub thoob cov hniav ntawm lub thoob log excavator tsis loj, thiab lub zog tuaj yeem tsuas yog hv315 Tsis muaj kev cuam tshuam, nruab nrab theem hauv-situ kev nyuaj siab rub cov khoom hnav-resistant rau kev puas tsuaj. , thiab nws cov hnav tsis kam yog zoo ib yam li cov pa roj carbon steel qauv. Ib txheej ntawm hnav-resistant aluminium alloy yog sprayed rau ntawm qhov chaw ntawm pheej yig carbon steel los yog siab alloy steel qhov chaw, uas tsis tsuas yog txhim kho cov hnav tsis kam ntawm cov khoom, tab sis kuj muaj zog ductility. Cov yam ntxwv no tsuas yog siv rau hauv tus account qhov kev ua tau zoo ntawm qhov yuav tsum tau ua ntawm lub thoob cov hniav ntawm lub excavator, thiab kev puas tsuaj rau cov tshuaj tsuag vuam txo cov kev cai ntawm cov khoom siv raw thiab tus nqi ntawm cov khoom siv raw. Tus qauv ntawm aluminium alloy series cov khoom uas muaj siab manganese steel phaj nto tsuag vuam yog xaiv cov tshuaj tsuag vuam aluminium alloy nrog siab hardness thiab zoo hnav tsis kam kom deb li deb tau yog tias nws tuaj yeem tiv thaiv kev sib tsoo ntawm cov ntaub ntawv raw hauv daim ntawv thov. Nyob rau hauv qhov chaw uas feem ntau pom tseeb, nws muaj peev xwm txau weld aluminium alloy nrog ferritic alloy steel. Txawm li cas los xij, los ntawm kev soj ntsuam saum npoo ntawm siab manganese steel thoob cov hniav thiab cov tshuaj tsuag welded siab chromium cam khwb cia hlau aluminium alloy thoob cov hniav, nws pom tias cov yeeb nkab zawj ntawm siab manganese steel puas los ntawm cov khoom siv tiv taus yog tob dua li cov chromium cam khwb cia hlau siab. , uas qhia tau hais tias hnav tsis kam ntawm high cobalt alloy npua hlau yog siab dua li ntawm siab manganese hlau. Yog li ntawd, nws yog feem ntau pom zoo kom txau weld siab chromium cam khwb cia hlau aluminium alloy los yog austenitic aluminium alloy npua hlau rau saum npoo ntawm thoob hniav thiab thoob.
