Rail ASCE 60 Steel Qib Thiab Cov Khoom Siv Khoom
Thaum ntsuasUAS 60, ntau tus engineers pib tsom rau cov ntaub ntawv geometric xws li ASCE 60 rail qhov ntev, 60 lbs ASCE rail qhov ntev, lossis 60 lbs rail qhov ntev hauv mm. Txawm li cas los xij, cov khoom siv sab hauv yog qhov kawg txhais qhov kev ua tau zoo, hnav tsis kam, thiab kev pabcuam lub neej. Txawm hais tias ob txoj hlua sib koom ua ke zoo ib yam ASCE 60 rail qhov ntev, siv cov qib hlau tsis raug tuaj yeem ua rau lub sijhawm ntxov deformation, tawg, lossis txawm tias tam sim ntawd tsis ua haujlwm hauv qab thauj khoom.

Vim li cas thiaj xaiv Txoj Cai Qib Qib Hlau Rau 60 lb Rail
Txawm tias60 lb ASCE railua raws li tus qauv profile thiab60 lbs rail hnyav ib 'meter', nws sab hauv metallurgical muaj pes tsawg leeg txiav txim seb nws ua li cas raws li kev ua haujlwm tiag tiag. Tsawg- carbon steels yuav pib txo tus nqi yuav khoom, tab sis lawv tsis muaj qhov tawv thiab hnav tsis kam yuav tsum tau rov ua dua lub log.
Hauv kev xyaum, siv cov khoom siv tsis tsim nyog rauUAS 60tuaj yeem ua rau kev tsheb ciav hlau lub taub hau flattening, hnav ntau dhau, lossis tawg hauv cov khoom hnyav. Rau cov neeg siv kev lag luam, qhov no txhais ncaj qha rau hauv cov nqi kho dua, nce sijhawm poob qis, thiab muaj peev xwm muaj kev nyab xeeb. Yog li ntawd, kev xaiv cov ntaub ntawv tsis yog ib txoj kev xaiv xwb -nws yog ib tug ntev - kev txiav txim siab peev.
Common Steel Qib Rau Rail ASCE 60
ASCE 60 (60 lb / yd) rail yog feem ntau tsim los siv siab - purity carbon steel, nrog cov qib thawj suav nrog55Q, Q235B, U71Mn, thiabASTM A1(Standard carbon steel). Cov tsheb ciav hlau no tau siv dav hauv kev tsheb ciav hlau, kev tsheb ciav hlau, kev siv mining, thiab cranes, feem ntau ua raws li ASTM cov qauv rau kev ua haujlwm ntev thiab hnav tsis kam.
Cov pa roj carbon (C) yog qhov tseem ceeb cuam tshuam rau hardness, thaum manganese (Mn) txhim kho toughness thiab hnav tsis kam. Silicon (Si) pab txhawb lub zog, tab sis phosphorus (P) thiab sulfur (S) yuav tsum tau tswj nruj me ntsis. P thiab S ntau dhau tuaj yeem ua rau brittleness, tshwj xeeb tshaj yog nyob rau hauv qis - qhov kub thiab txias, ua rau muaj kev pheej hmoo ntawm kev tawg.

Cov khoom siv tshuab no ncaj qha cuam tshuam li cas ASCE 60 rail coj tus cwj pwm hauv qab thauj khoom. Piv txwv li, hardness ntau dua txhim kho kev hnav tsis kam, thaum txaus elongation ua kom lub tsheb ciav hlau tuaj yeem nqus tau kev ntxhov siab yam tsis muaj kev ua tsis tiav.
Yuav ua li cas xaiv cov khoom cuam tshuam rau vuam thiab dabtsi yog khoov
Cov khoom muaj pes tsawg leeg muaj qhov cuam tshuam ncaj qha rau kev tsim thiab kev teeb tsa. RauUAS 60, weldability txo qis thaum cov ntsiab lus carbon nce. Siab -lub zog steels zoo li U71Mn yuav tsum tau tswj nruj thaum lub sij hawm vuam thermite, suav nrog cov txheej txheem preheating thiab txias kom tsis txhob tawg.
Nyob rau hauv cov nqe lus ntawm dabtsi yog khoov, cov ntaub ntawv sib txawv qhia txawv yooj. Cov pa roj carbon qis xws li Q235 tso cai kom nruj dua bending radii, ua rau lawv haum rau cov kab nkhaus. Hauv qhov sib piv, qib siab - lub zog siv hauv60 lb ASCE railfeem ntau yuav tsum tau loj dua qhov tsawg kawg nkaus khoov radii kom tsis txhob muaj kev puas tsuaj thaum lub sijhawm ua haujlwm txias.
