24kg steel rail yog dab tsi?
Lub 24kg steel rail txais ib qho I-zoo li tus ntoo khaub lig-section, featuring zoo heev dabtsi yog khoov tsis kam, uas muaj peev xwm tiv taus lub siab thiab cuam tshuam quab yuam los ntawm lub log. Nws nto yog du, ncaj tom qab dov, tsis muaj qhov tseem ceeb bending lossis torsion, thiab lub ntsej muag kawg tsis muaj qhov tsis xws luag xws li shrinkage marks lossis interlayers, kom ntseeg tau qhov smoothness thiab kev nyab xeeb ntawm kev ua haujlwm ntawm lub tsheb ciav hlau.
Kev ua tau zoo thiab kev pabcuam lub neej ntawm lub teeb steel rail nyob ntawm nws qhov hnyav tsis tsuas yog nyob ntawm nws qhov hnyav, tab sis kuj nyob ntawm nws cov qauv tsim thiab kev tsim khoom zoo. GB Standard 24KG Lub Teeb Steel Rail yog tsim los muab kev ua haujlwm txhim khu kev qha hauv lub teeb -load railway daim ntaub ntawv thaum tuav tswj zoo heev manufacturability thiab installation efficiency.

Tus qauv tsim ntawm 24KG Lub Teeb Steel Rail
| Rail Section Part | Muaj nuj nqi |
|---|---|
| Rail taub hau | Bears log load thiab resists hnav |
| Rail Web | Hloov loads thiab absorbs kev nyuaj siab |
| Rail Base | Xyuas kom ruaj khov thiab fastening |
Covoptimized taub hau - rau - puag pivntawm 24kg kev tsheb nqaj hlau ua kom cov khoom thauj khoom zoo thaum txo cov khoom siv tsawg, ua rau nws tsim nyog rau kev tsheb ciav hlau uas nquag tab sis nruab nrab.
Dimensional Accuracy thiab Tolerances
| Yam khoom | GB Standard Requirement |
|---|---|
| Qhov hnyav sib txawv | ±2% |
| Ntev Ntev | ± 5 hli |
| Kev ncaj | Tsawg dua lossis sib npaug li 1/1000 |
| Twist | Tsawg dua lossis sib npaug li 1/2000 |
Kev tswj nruj nruj kom ntseeg tau tias kev txhim kho kev tsheb nqaj hlau du thiab txo kev vibration thaum ua haujlwm.
Manufacturing Txheej txheem cej luam
Kev xaiv raw khoom
High- zoo carbon steel billets raug xaiv kom ua tau raws li GB tshuaj muaj pes tsawg leeg yuav tsum tau ua.
Kub Rolling
Tswj dov cov ntaub ntawv cov kev tsheb ciav hlau meej thiab txhim kho cov qauv hauv cov nplej.
Txias thiab Ncaj
Kev ua kom txias kom zoo tiv thaiv qhov kev ntxhov siab seem thiab txhim kho qhov ruaj khov.
Kev tshuaj xyuas thiab kuaj
Kev tshuaj xyuas tshuaj, kev sim tshuab, thiab kev kuaj xyuas qhov ntsuas kom ua raws li.
Hom tshuaj muaj pes tsawg leeg
| Element | Cov ntsiab lus (%) |
|---|---|
| Cov pa roj carbon (C) | 0.50–0.60 |
| Manganese (Mn) | 0.60–0.90 |
| Silicon (Si) | Tsawg dua lossis sib npaug li 0.40 |
| Phosphorus (P) | Tsawg dua lossis sib npaug li 0.040 |
| Sulfur (S) | Tsawg dua lossis sib npaug li 0.040 |
Qhov kev sib xyaw no muab qhov sib npaug ntawm hardness, toughness, thiab weldability.
