90RA rail is a type of railway track steel rail that adheres to the standards set by the American Railway Engineering and Maintenance-of-Way Association (AREMA). It is commonly used in railway transportation systems, particularly in the United States and other countries that follow AREMA standards.
The 90RA rail is made from high-quality carbon steel, which provides it with excellent strength and hardness. The standard dimensions of the rail are 90 paun setiap halaman (Kira 45 kilogram per meter) in weight, 130.2 millimeters in bottom width, 142.9 millimeters in height, Dan 12-25 panjang meter. It also features a specific head shape and profile design that ensures stability and smoothness during operation.
One of the key advantages of the 90RA rail is its excellent wear resistance and impact resistance, which make it suitable for heavy loads and high-speed operations. Selain itu, it has good welding and processing properties, making it easy to install and maintain.
The 90RA rail is widely used in various railway transportation systems, including mainline railways, kereta api perlombongan, Kereta Api Perindustrian, and more. Its versatility and durability make it an ideal choice for railway operators who require reliable and long-lasting track infrastructure.
In terms of manufacturing process, the production of 90RA rail involves several steps, including steelmaking, Bergolek, Rawatan haba, and finishing. High-quality raw materials are selected and melted in a furnace before being rolled into the desired shape and size. The rail is then subjected to heat treatment processes such as quenching and tempering to enhance its mechanical properties.
To ensure the quality and safety of the 90RA rail, rigorous testing and inspection procedures are carried out at various stages of production. These tests include non-destructive testing methods such as ultrasonic testing, magnetic particle testing, and radiographic testing, as well as destructive testing methods like tensile testing and bend testing.
Keseluruhan, the 90RA rail is a high-performance railway track steel rail that offers excellent durability, Kebolehpercayaan, dan prestasi.

Standard EN 13674 - 1:2003 terdiri daripada dua bahagian utama:

− ujian kelayakan dan ujian penerimaan

Ujian kelayakan adalah beberapa ujian lain yang sebelum ini dijalankan, sebagai contoh, ketangguhan patah. Ujian penerimaan mencirikan sifat ujian yang ditetapkan, yang memastikan pengeluaran rel berkualiti tinggi, dan keperluan ujian pentadbiran kereta api.

Kualiti rel adalah berdasarkan nilai kekerasan yang diukur, di mana mereka memperkenalkan label baru untuk rel keluli.

Ujian kelayakan

Ujian kelayakan mesti dijalankan sekurang-kurangnya satu dalam lima tahun dan utama

perubahan dalam teknologi, rel pengeluaran. Tekanan sisa ujian tambahan dibawa

keluar pada semua jenis rel keluli setiap dua tahun maksimum, dengan syarat bahawa membujur

kadar terikan di rel boleh berjumlah sehingga 250 Mpa.

Peperiksaan kelayakan yang ditetapkan adalah seperti berikut:

− ketangguhan patah

− keletihan retak kadar pertumbuhan

− ujian keletihan

− tekanan sisa dalam kaki kereta api

− variasi garis tengah

− kekuatan tegangan dan pemanjangan

− pengasingan

− keperluan kelayakan lain

Ujian penerimaan

Dalam ujian penerimaan dijalankan satu siri ujian makmal seperti:

− komposisi kimia (kandungan maksimum unsur-unsur berikut: H, O, Al, V, Unsur N dan oligo)

− mikrostruktur (meningkatkan x 500)

− darjah lapisan hangus decarburizing (dibenarkan sehingga 0.25 Mm)

− kesucian keluli (terutamanya kehadiran oksida)

− makrostruktur (Ujian Baumann)

− kekerasan

− kekuatan tegangan

Rel ujian penerimaan lain adalah:

− toleransi dimensi

− kriteria (templat kawalan)

− keperluan pemeriksaan / toleransi untuk kualiti dalaman dan kualiti permukaan

Keadaan dalaman diperiksa ultrasound dalam kawalan proses berterusan, dan termasuk sekurang-kurangnya 70% kepala dan sekurang-kurangnya 60% Web.

- Standard of UIC 860 V: 1996 - ditetapkan empat jenis rel keluli pearlite dalam julat kekuatan tegangan dari 700 Untuk 1300 Mpa.

- Standard EN 13674 - 2003, menyediakan tujuh jenis kekerasan keluli pearlite dalam julat 200 Untuk 390 HBV, jenis keluli mengikut EN 13674, berdasarkan nilai-nilai kekerasan (R 200, R 220, R 260, R 260 Mn, 320 Cr, 350 HT, 350 LHT).
