Drilling Thiab Milling Tshuab Tau Zoo Yasity Thiab Toughness

Drilling thiab milling tshuab rau lub koob npe ua yeeb yam, tsis tshua muaj cov roj txias txias kev sib piv, elongation, daim ntawv cog lus lub zog ntawm cov hlau thiab pob zeb loj yog qhov loj, haum rau drilling thiab milling tshuab hauv me me thiab nruab nrab lub koob npe paj yeeb yam qauv sib xyaw collocation, drilling thiab milling tshuab kuj tseem haum rau xaim mesh vuam. Cov yam ntxwv ntawm 5 yam ntxwv thiab kev siv - kev kho cua sov ntawm cov hlau nrog lub zog siab, tab sis kuj muaj cov khoom yas zoo thiab tawv yog qhov tshwj xeeb rau cov tswv cuab muaj koob npe. - tab sis nws qhov drilling thiab milling tshuab rau muaj zog rhiab heev, cuam tshuam los ntawm kev nyuaj siab thiab qhov tsis xws luag, yuav tsum tiv thaiv xeb thiab nicks, thiab lwm yam. Thaum tshav kub kub kho kho steel bar rau prestressed pob zeb ua cov cuab yeej muaj zog ntawm nominal inch hli 0.2 sigma raws sigma qib B 10, tsis tshaj MPa%, tsis tsawg tshaj 68.210 40Si 2 qhov drilling thiab milling tshuab 48Si 2 manganese manganese 45Si steel kuaj siv steel xov uas muaj 2 CR 1325147062.3 2.3.1 cov khoom lag luam tus naj npawb sawv cev rau tus naj npawb ntawm cov khoom ntsuas tau 1 Tensile xeem ntawm qis carbon steel sawb dabtsi yog khoov xeem 2 (txawv cov hauv paus hniav) tensile xeem 2 (2 lub hauv paus) 2 khoov kuaj (2 keeb kwm) drilling thiab tshuab milling tshuab kuaj thiab kuaj xyuas cov nyiaj tau los ntawm cov nyiaj tau los, cov naj npawb ntawm qhov drilling thiab lub tshuab milling qhov hnyav tsis ntau dua 60 tons ntau lub zog ntsuas nrog cov kab sib tw nominal txoj kab txiav thiab lub tshuab drilling tau suav raws li qhov chaw hla ntawm thaj tsam.
