Hlau railstsim lub hauv paus ntawm railway thiab industrial khiav systems. Lawv coj lub log kom nyab xeeb thaum txhawb nqa cov khoom tseem ceeb thiab faib kev ntxhov siab sib npaug rau cov neeg pw tsaug zog lossis lub hauv paus. Kev xaiv ntawm rail steel cuam tshuam rau durability, kev nyab xeeb, thiab kev ua haujlwm ntev -. Ntawm cov hlau uas nquag siv, Q235 steel yog dav siv rau hauv kev lag luam rails, crane lem, thiab lub teeb railway systems vim nws qhov sib npaug ntawm lub zog, ductility, thiab nqi -efficiency.
Dab tsi yog cov khoom ntawm Q235 steel?
Q235 yog ib qho qis - carbon structural steel qauv hauv qabGB/T 700-2006, haum rau lub teeb - mus rau nruab nrab - lub luag haujlwm rails. Nws cov khoom ua kom zoo weldability, nruab nrab lub zog, thiab hloov tau yooj yim rau kev lag luam.

| Elongation | Ntau dua lossis sib npaug li 26 | % | Ntsuas ductility thiab yooj |
| Hardness | 38–47 | HB | Nruab nrab hnav tsis kam |
| Cov ntsiab lus carbon | 0.12–0.22 | % | Tsawg carbon ua kom weldability |
| Manganese (Mn) | 0.30–0.70 | % | Txhim khu lub zog thiab toughness |
| Sulfur (S) | Tsawg dua lossis sib npaug li 0.045 | % | Minimizes brittleness |
| Phosphorus (P) | Tsawg dua lossis sib npaug li 0.045 | % | Txhim kho ductility |
Q235 Steel Ua li cas hauv kev siv Rail?
Q235 steel kev sib xyaw ua ke ntawm lub zog, yoog raws, thiab kev ua haujlwm ua rau nws tsim nyog rau ntau daim ntawv thov kev tsheb nqaj hlau:
- Lub teeb Industrial Rails:Txhawb nqa nruab nrab loads hauv factories thiab warehouses.
- Crane Tracks:Zoo tagnrho rau lub teeb gantry cranes nrog loads txog 10 tons ib lub log.
- Mining thiab Temporary Rails:Siv nyob rau hauv qhov chaw kaw lossis ib ntus kev thauj khoom.
| Rail Hom | Khoom siv | Qhov hnyav (kg / m) | Max Load | Daim ntawv thov |
|---|---|---|---|---|
| 22kg Lub Teeb Rail | Q235 | 22.3 | 10 ton | Factory thiab warehouse lem |
| JIS 22kg Rail | Q235 | 22.3 | 10 ton | Lub teeb crane rails |
| 12kg Mining Rail | Q235 | 12 | 5-6 tons | Kev thauj mus los ib ntus |
GNEE RAIL muab cov khoom txhawb nqa xws li cov ntses ntses, rail clips, roj hmab pads, thiab thauj tog rau nkoj bolts, xyuas kom cov ntsia hlau ntsia tau zoo thiab ntseeg tau.
Q235 Steel piv rau Q355 Hlau li cas?
Thaum Q235 steel zoo tagnrho rau lub teeb thiab nruab nrab - daim ntawv thov,q 355 uamuab lub zog tawm los ntau dua thiab txhim kho qis - qhov kub thiab txias ua haujlwm rau hnyav - lub luag haujlwm thiab sab nraum zoov.
| Khoom | Q235 | Q355 | Qhov txawv |
|---|---|---|---|
| Yield zog | Ntau dua lossis sib npaug li 235 MPa | Ntau dua lossis sib npaug li 355 MPa | Q355 yog ~ 51% muaj zog dua |
| Qhov kawg Tensile Strength | 370-500 MPa | 470-630 MPa | Q355 tiv taus ntau dua |
| Elongation | Ntau dua lossis sib npaug li 26% | Ntau dua lossis sib npaug li 20% | Q235 yog ductile ntau dua |
| Corrosion Resistance | Nruab nrab | Zoo | Q355 resists hnyav ib puag ncig zoo dua |
