Ntev npaum li cas steel rails kav ntev?

Hlau Rails, tseem hu ua rail profiles, yog cov khoom tseem ceeb ntawm railway lem. Nws txoj haujlwm yog coj lub log ntawm cov tsheb thiab tsheb; tiv taus lub zog loj ntawm lub log, thiab dhau lub zog quab yuam rau cov tsheb ciav hlau.

 

 

Ntev npaum li cas steel rails kav ntev?

Kev pab lub neej ntawm steel rails nyob ntawm cov khoom siv tsheb ciav hlau, kev siv, kev thauj khoom, thiab kev saib xyuas. High- cov hlau zoo, xws li cov uas muab los ntawm GNEE RAIL, yog tsim los rau ntev - lub sij hawm durability nyob rau hauv ob qho tib si mainline railways thiab industrial daim ntaub ntawv xws li cranes thiab ports.

 

Dab tsi cuam tshuam rau Lifespan ntawm Steel Rails?

 

Ob peb yam txiav txim siab ntev npaum li cas lub tsheb ciav hlau yuav kav ntev:

 

• Khoom muaj pes tsawg leeg:Rails ua los ntawm qib siab -qib hlau zoo li U71Mn, U75V, lossis R350HT muaj zog tensile ntau dua, hardness, thiab qaug zog.

 

 

Qib Steel	C(%)	Si	Mn	Cr	V	P	S	Tensile zog (Rm / MPa)
ua 71mn	0.65~0.76	0.15~0.58	0.70~1.40	–	–	Tsawg dua lossis sib npaug li 0.035	Tsawg dua lossis sib npaug li 0.030	Ntau dua lossis sib npaug rau 880
U75V	0.71~0.80	0.50~0.80	0.75~1.05	–	0.04~0.12	Tsawg dua lossis sib npaug li 0.035	Tsawg dua lossis sib npaug li 0.030	Ntau dua lossis sib npaug li 980
ua 78crv	0.72~0.82	0.50~0.80	0.70~1.05	0.30~0.50	0.04~0.12	Tsawg dua lossis sib npaug li 0.035	Tsawg dua lossis sib npaug li 0.030	Ntau dua lossis sib npaug rau 1080
U77MnCr	0.72~0.82	0.10~0.50	0.80~1.10	0.25~0.40	–	Tsawg dua lossis sib npaug li 0.035	Tsawg dua lossis sib npaug li 0.025	Ntau dua lossis sib npaug li 980
ua 76kr	0.71~0.81	0.50~0.80	0.80~1.10	0.25~0.35	0.04~0.08	Tsawg dua lossis sib npaug li 0.035	Tsawg dua lossis sib npaug li 0.025	Ntau dua lossis sib npaug rau 1080

 

• Rail hom thiab qhov hnyav:Heaver rails (piv txwv li, 60-75 kg / m) tuaj yeem tiv taus ntau dua thiab siv tau ntev dua li cov tsheb ciav hlau (piv txwv li, 9-30 kg / m).

 

 

Kev faib tawm		Qhov siab (mm)	Lub taub hau (mm)	Hauv qab (mm)	Thickness (mm)	Qhov hnyav (kg / m)
Lub Teeb Rail	8 KG / M	65	25	54	7	8.42
	9 KG / M	63.5	32.1	63.5	5.9	8.94
	12 KG / M	69.85	38.1	69.85	7.54	12.2
	15 KG / M	79.37	42.86	79.37	8.33	15.2
	18 KG / M	80	40	80	10	18.06
	22 KG / M	93.66	50.8	93.66	10.72	22.3
	24 KG / M	107	51	90	10.9	24.46

• Tsheb thauj mus los thiab ceev:Rails nyob rau hauv siab -ceev los yog hnyav freight kab hnav sai dua vim muaj kev ntxhov siab thiab dov kev sib cuag qaug zog.

 

• Environmental tej yam kev mob:Rails nyob rau hauv corrosive los yog huab cua huab cua (coastal, high humidity, los yog txias cheeb tsam) yuav tsum tau zoo corrosion kuj.

 

• Cov kev tswj xyuas:Kev sib tsoo tsis tu ncua, lubrication, thiab fastener checks prolong rail lub neej.

 

Ntev npaum li cas Ntau Hom Hlau Rails feem ntau kawg?

 

Rail Hom	Hom Lifespan	Sau ntawv
Lub teeb rail (9-30 kg / m)	10-15 xyoo	Feem ntau siv nyob rau hauv cov kab kev lag luam lossis lub teeb -cov dej num
Hnyav rail (50-75 kg / m)	25-40 xyoo	Mainline freight thiab neeg caij tsheb kab
Crane Rail (QU70-QU120) 1.	15-25 xyoo	Nyob ntawm crane zaus, load, thiab txij nkawm
High -Speed ​​rail (UIC60/R350HT)	30-50 xyoo	Yuav tsum tau kuaj xyuas thiab kev tiv thaiv tsis tu ncua
