Litšobotsi tsa Mantlha tsa Likarolo tsa Cast Steel ho Rail Transit

Thepa le Mechini Thepa
Mofuta oa Material: Haholo-holo litšepe tse entsoeng ka carbon (tse kang ZG20-45#, ZG270-500) le tšepe ea alloy e tlaase, e nang le carbon content hangata e pakeng tsa 0.2% -0.45%, le likarolo tse kang Cr, Ni, le Mo li ka eketsoa ho ntlafatsa matla le ho tiea.

Matla a Phahameng le Matla a Phahameng: Matla a thata a ka fihla ho 500-700 MPa, 'me a ama matla a maholo ho feta kapa a lekana le 20 J/cm², a loketse ho mamella meroalo e phahameng le maemo a ts'usumetso.

Isotropy e ntle: Sebopeho sa ka hare sa litšepe tse entsoeng ka tšepe se tšoana ho feta sa tšepe e entsoeng ka tšepe, 'me se na le liphapang tse nyane ka -mehato e meraro, e leng se etsang hore e tšoanelehe bakeng sa meaho e rarahaneng{1} ea ho beleha.

Litšobotsi tsa Tlhahiso le Ts'ebetso
E khona ho Theha Libopeho tse Ratang: Mokhoa oa ho lahla o ka etsa-likarolo tse rarahaneng tse kang li-rocker, liforeimi tse mahlakoreng, li-couplers, le liforeimi tsa bogie, ho fokotsa tlhoko ea ho cheselletsa.

Kalafo e Tloaelehileng ea Mocheso: Ho tloaeleha + ho futhumatsa kapa ho tima le ho futhumatsa hangata ho sebelisoa ho ntlafatsa sebopeho, ho imolla khatello ea maikutlo ka hare, le ho ntlafatsa ts'ebetso e phethahetseng.

Taolo ea Boleng bo Matla: E hloka tlhahlobo ea ultrasonic (UT), magnetic particle inspection (MT), le tlhahlobo e tlase-magnification/high-magnification metallographic ho netefatsa hore ha ho na likoli tse kang porosity, shrinkage cavities, kapa cracks.
