Dab tsi yog jis hauv steel?
Hauv kev lag luam steel, JIS hais txogJapanese Industrial Standards, lub teb chaws tus qauv tsim los ntawm Nyiv los tswj cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, qhov ntev, kev kam rau siab, thiab kev sim cov txheej txheem ntawm cov hlau thiab lwm yam khoom lag luam. Thaum cov khoom siv hlau tau sau tias "JIS tus qauv," nws txhais tau hais tias cov khoom tau raug tsim thiab tshuaj xyuas raws li JIS cov lus qhia tshwj xeeb, ua kom muaj kev sib raug zoo thiab sib hloov hauv kev siv engineering.
Rau txoj kev tsheb ciav hlau thiab cov ntaub ntawv taug qab, JIS cov qauv siv dav siv rau cov tsheb ciav hlau, tsheb ciav hlau fasteners, baseplates, fishplates, thiab bolts, tshwj xeeb tshaj yog nyob rau hauv metro systems, industrial railways, ports, thiab mining thauj kab. Raws li lub thoob ntiaj teb railway fastener thiab rail tsum,GNEE RAILkhoom siv JIS-raws li steel rails thiab ua kom tiav fastening systems, thaum tseem txhawb nqaGB, EN/UIC, BS, DIN,thiabAREMAcov qauv rau cov haujlwm thoob ntiaj teb.

Dab tsi ntawm cov hlau yog them los ntawm JIS Standards?
JIS tsis tau piav qhia txog qib steel ib leeg, tab sis theejib tsev neeg ua tiav ntawm cov qauv steel, npog carbon steel, alloy steel, stainless hlau, caij nplooj ntoos hlav steel, thiab tshwj xeeb - lub hom phiaj steels. Hauv cov ntawv thov kev tsheb ciav hlau, cov pawg tseem ceeb tshaj plaws suav nrog kev tsheb nqaj hlau thiab cov qauv hlau siv hauv cov fasteners thiab cov khoom siv.
Piv txwv ntawm Common JIS Steel Qeb:
| JIS Code | Qeb Hlau | Tej kev siv |
|---|---|---|
| TIAB SA 3101 | Rolled steels rau cov qauv dav dav (piv txwv li, SS400) | Baseplates, steel qauv |
| TIAB SA 4051 | Cov pa roj carbon steel rau kev siv tshuab (piv txwv li, S45C) | Bolts, shafts, fastener qhov chaw |
| TIAB SA 3441 | Alloy steels rau cov qauv | Siab -cov khoom muaj zog |
| JIS E 1101 / E 1103 | Hlau rails | Taug kev tsheb ciav hlau rau metro thiab kev lag luam |
Rau kev tsheb ciav hlau, JIS rail steel yog tsim los sib npaugsiab hardness, hnav tsis kam, thiab txaus toughness, ua kom lub neej ntev kev pab cuam nyob rau hauv rov qab log loads.GNEE RAILkhoom siv JIS rail seem ua ke nrog cov clips sib xws, cov ntaub qhwv, thiab cov phaj hauv qab, thiab tseem tuaj yeem muab lwm cov ntaub ntawv thaum cov neeg siv khoom xav tau kom phim lwm lub teb chaws cov qauv.
JIS Steel txawv li cas ntawm GB, EN, lossis ASTM Steel?
JIS steel qauv ua haujlwm zoo ib yam rauGB (Tuam Tshoj), EN / UIC (Tebchaws Europe), thiab ASTM / AREMA (USA), tab sis lawv txawv ntawm qib npe, txwv tshuaj lom neeg, cov txheej txheem kuaj, thiab qee zaum kev ua tau zoo. Txawm tias thaum ob lub steels muaj qhov sib xws, lawv tsis tuaj yeem hloov pauv yam tsis muaj kev txheeb xyuas kev paub.
Simplified Comparison ntawm Steel Standard Systems:
| Standard System | Thaj tsam | Hom Rail Steel Qib | Ntsiab Feature |
|---|---|---|---|
| JIS | Nyiv | JIS rail qib (ib JIS E) | Kev nruj me ntsis & kev tswj kom zoo |
| GB | Tuam Tshoj | U71Mn, U75V | Dav dav rau lub teeb rau hnyav thauj |
| EN / UA | Teb chaws Europe | R260, R350HT | Interoperability nyob rau hauv lub network |
| ASTM / AREMA | Teb chaws USA | Siab - carbon rail steels | Hnyav freight tsom |
Vim tias qhov sib txawv no, cov phiaj xwm kev tsheb ciav hlau yuav tsum xaiv tsis yog cov tsheb ciav hlau xwbhnyav thiab profile, tab sis kuj covyog tus qauv systemkom phim cov neeg pw tsaug zog, fasteners, thiab cov khoom siv tu.
Txij xyoo 2008,GNEE RAILtau muab steel rails ntawm cov qib sib txawv rau ntau tshaj 18 xyoo, steel rails los ntawm GNEE yog heev recommened nyob rau hauv Tuam Tshoj thiab txawv teb chaws.Wtih txiav ntug khoom, GNEE ua tau zoo steel rails uas tau raws li cov kev cai ntawm feem ntau lub teb chaws. Standard rail, lub taub hau hardened rail, hnyav rail, lub teeb rail, crane rail thiab lwm yam yog tag nrho cov muaj nyob ntawm no, raws li ib tug ntawm cov Tuam Tshoj lub ntsiab rail tsum, GNEE RAIL tau ua hauj lwm rau muab kev lag luam ntsuab railway khoom thoob plaws lub ntiaj teb no.
