115Reli ya RE

115RE rail also be named TR57 AREMA standard steel rail, Inatumika sana katika eneo la Amerika, Tunaweza kuizalisha kwa utaratibu, MOQ ni 500 Tani. Material can be SS and HH, Urefu unaweza kuwa 39 miguu kwa 80 Miguu.

115Reli ya RE ni aina ya reli ya chuma inayotumiwa katika nyimbo za reli, primarily in North America. ya “115TENA” Jina linahusu uzito wa reli, ambayo ni takriban 115 paundi kwa yadi (57.1 kilo/m). Imeainishwa kama reli nzito na hutumiwa kawaida kwa nyimbo kuu, ikiwa ni pamoja na reli za mizigo na abiria.

One of the significant advantages of 115RE rail is their durability and strength, which can withstand the significant loads and stresses imposed by trains. These rails have a specific profile that conforms to industry standards, ensuring a smooth ride and stable operation for trains.

115RE rail is typically made from high-strength carbon steel, which provides excellent wear resistance and durability. They are installed on concrete sleepers or wooden ties and secured to the sleepers with various fastening systems, Kama vile vipande vya vipande au spikes. The rails’ dimensions and properties conform to the American Railway Engineering and Maintenance-of-Way Association (AREMA) Viwango, which specify the requirements for different types of railway tracks.

An essential aspect of 115RE rail is their versatility, as they can be used for various applications, ikiwa ni pamoja na nyimbo kuu, sidings, and yards. They provide reliable performance, even under extreme weather conditions, and can withstand heavy traffic and loads.

In terms of maintenance, proper inspection and lubrication of the rail joints and fasteners play a vital role in ensuring the long-term performance of the 115RE rail. Regular inspection and replacement of worn or damaged rails can also help prevent accidents and ensure the safety of passengers and workers.

Jumla, 115RE rail is a durable and reliable type of steel rail that provides excellent performance for railway tracks. Its versatile application, Nguvu, and durability make it a popular choice for many railway operators in North America.

Standard EN 13674 - 1:2003 Ina sehemu kuu mbili:

− Mtihani wa kufuzu na vipimo vya kukubalika

Vipimo vya kufuzu ni baadhi ya vipimo vingine ambavyo awali vilifanyika, kama kwa mfano, Kuvunjika kwa ugumu. Vipimo vya kukubalika vinaonyesha mali ya vipimo vilivyoagizwa, ambayo inahakikisha uzalishaji wa reli zenye ubora wa hali ya juu, na mahitaji ya upimaji wa utawala wa reli.

Ubora wa reli unategemea maadili yaliyopimwa ya ugumu, ambayo walianzisha lebo mpya za reli za chuma.

Vipimo vya kufuzu

Upimaji wa sifa lazima ufanyike angalau moja katika miaka mitano na kubwa

Mabadiliko katika teknolojia, Reli za uzalishaji. Mafadhaiko ya ziada ya kupima mabaki yabebwa

nje juu ya aina zote za reli za chuma kila baada ya miaka miwili upeo, ilimradi kwamba longitudo

Kiwango cha shida katika reli kinaweza kufikia hadi 250 MPa.

Mtihani wa kufuzu uliowekwa ni ufuatao:

− kuvunjika kwa ugumu

− Kiwango cha ukuaji wa uchovu

− Upimaji wa uchovu

− Mkazo wa mabaki katika mguu wa reli

− tofauti ya mstari wa katikati

− nguvu ya tensile na elongation

− ubaguzi

− mahitaji mengine ya kufuzu

Vipimo vya kukubalika

Ndani ya upimaji wa kukubalika hufanywa mfululizo wa vipimo vya maabara kama vile:

− muundo wa kemikali (maudhui ya juu ya vipengele vifuatavyo: H, O, Al, V, Elementi za N na oligo)

− microstructure (Kuongezeka kwa X 500)

− shahada ya decarburizing charred layer (inaruhusiwa hadi 0.25 mm)

− usafi wa chuma (Hasa uwepo wa oksidi)

− macrostructure (Mtihani wa Baumann)

− ugumu

− nguvu ya tensile

Reli nyingine za upimaji wa kukubalika ni:

− uvumilivu wa vipimo

− vigezo (template ya kudhibiti)

− Mahitaji ya ukaguzi / uvumilivu kwa ubora wa ndani na ubora wa uso

Hali ya ndani inachunguzwa ultrasound katika udhibiti wa mchakato endelevu, na inajumuisha angalau 70% ya kichwa na angalau 60% Wavuti.

- Kiwango cha UIC 860 V: 1996 - imeagizwa aina nne reli ya chuma ya pearlite katika anuwai ya nguvu ya tensile kutoka 700 kwa 1300 MPa.

- Standard EN 13674 - 2003, hutoa aina saba za ugumu wa chuma cha pearlite katika anuwai 200 kwa 390 HBV, aina ya chuma kulingana na EN 13674, kulingana na maadili ya ugumu (R 200, R 220, R 260, R 260 Mn, 320 Cr, 350 HT, 350 LHT).
