Daim ntawv thov
Cutterhead hniav:
Cutterheads ntawm shield tunneling tshuab yog nruab nrog cov hniav rau txiav los ntawm cov pob zeb hauv av los yog av.Cov hniav no feem ntau yog ua los ntawm cov alloys nyuaj vim lawv cov hardness zoo heev thiab hnav tsis kam, ua kom muaj kev ua haujlwm ruaj khov hauv kev nyuaj hauv av.
Shield TBM Disc Cutters:
Shield TBM disc cutters yog cov khoom tseem ceeb uas txhawb nqa thiab coj lub taub hau cutter, ua kom muaj kev vam meej ntawm cov txheej txheem tunneling.Cov disc cutters kuj yuav tsum tau hnav-resistant thiab corrosion-resistant zog, uas alloys yuav muab tau.
Cutterhead Disc Cutter Rooj:
Cov rooj zaum tuav lub cutterhead hniav nyob rau hauv qhov chaw kuj feem ntau siv cov ntaub ntawv alloy los xyuas kom meej cov hniav stability thiab durability.
Drill Bits thiab Cutting Tools:
Hauv qee cov ntaub thaiv npog tunneling, cov khoom siv tho thiab lwm cov cuab yeej txiav tau siv.Kev tsim khoom ntawm cov cuab yeej no feem ntau suav nrog cov ntaub ntawv alloy los xyuas kom muaj peev xwm txiav txaus thiab lub neej ntev.
Yam ntxwv
Hardness:
Alloys nthuav tawm tshwj xeeb hardness, tswj kev ruaj khov txiav kev ua haujlwm nyob rau hauv kev kub siab thiab kev sib txhuam, yog li ncua lub neej ntawm cov cuab yeej.
Hnav Resistance:
Txiav los ntawm cov pob zeb hauv av thiab cov cuab yeej hauv av kom hnyav hnyav.Alloys hnav tsis kam ua rau cov hniav thiab cov cuab yeej txiav kom tswj tau cov kev ua haujlwm zoo hauv qhov chaw hnyav.
Corrosion Resistance:
Shield tunneling tshuab tuaj yeem ntsib cov dej noo, corrosive tshuaj, thiab lwm yam hauv av.Alloys ' corrosion kuj pab tiv thaiv cov cuab yeej los ntawm kev puas tsuaj.
Thermal stability:
Thaum lub sij hawm tunneling, cov cuab yeej tsim hluav taws xob vim kev sib txhuam.Alloys feem ntau muaj qhov zoo thermal stability, tswj kev ua haujlwm zoo ib yam txawm tias nyob rau hauv qhov kub thiab txias.
Lub zog:
Alloys feem ntau muaj lub zog siab, uas yog qhov tseem ceeb rau kev tiv thaiv kev txiav thiab kev cuam tshuam quab yuam.
Hauv cov ntsiab lus, cov alloys ua lub luag haujlwm tseem ceeb hauv daim ntaub thaiv kev siv lub tshuab tunneling, muab cov yam ntxwv xws li hnav tsis kam, corrosion kuj, thiab siab hardness los xyuas kom meej kev ua haujlwm zoo hauv qhov chaw hauv av.Ntau hom alloys yog siv raws li cov kev cai tshwj xeeb engineering thiab cov khoom siv.
