Cov lus nug nquag
Q1: Dab tsi yog cov yam ntxwv tseem ceeb ntawm ASCE 60 rail?
A: ASCE 60 tus qauv tsheb ciav hlau muaj qhov tshwj xeeb geometric layout qhov twg tag nrho qhov siab (107.95 hli) zoo ib yam rau lub hauv paus flange dav (107.95 hli). Nws muaj qhov hnyav nominal ntawm 29.76 kg ib meter (60 lbs / yard), ua rau nws haum rau lub teeb - mus rau - nruab nrab dov Tshuag.
Q2: Vim li cas 55Q steel qib siv rau ASCE 60LB rails?
A:55Q carbon steel muab kev pom zoo ua ke ntawm carbon (0.55% tseeb) thiab manganese (0.73% tseeb). Qhov kev sib piv tshuaj no ua kom lub zog tensile tsawg kawg nkaus ntawm 685 MPa (nrog GNEE cov khoom siv tiag tiag ntawm 720 MPa), tiv thaiv lub taub hau ntawm kev deformation thaum khaws cov khoom elastic txaus los tiv thaiv kev ua haujlwm tsis ua haujlwm nyob rau hauv kev thauj khoom.
Q3: Koj puas muab cov khoom sib koom ua ke (fishplates) rau ASCE 60LB rails?
A:Yog lawm, peb muab cov khoom siv ua kom tiav. Rau ASCE 60LB profile, peb tsim cov qauv sib txuam 4-qhov lossis 6-qhov sib koom ua ke, nrog rau kev taug qab bolts, caij nplooj ntoos hlav ntxhua khaub ncaws, thiab sib xws soleplates / clips.
