Kakšni so proizvodni materiali železniških konic?
Railway spikes have very strict requirements on materials and performance. They usually use high-quality medium carbon steel or alloy steel as raw materials. After forming, they undergo heat treatment processes such as quenching and tempering and normalizing to improve their strength and wear resistance. In order to adapt to various climatic environments, some products will also undergo anti-corrosion treatments na primer pocinkanje, dakromet in elektroforetsko slikarstvo, da bi zagotovili, da še vedno ohranjajo dobro strukturno stabilnost pod visoko vlažnostjo, visoko soljo ali ekstremnimi hladnimi pogoji .
Ali poznate standarde uspešnosti železniških konic?
In international or Chinese standards, there are clear requirements for the performance of threaded spikes. For example, their tensile strength is usually required to be no less than 700MPa, and the accuracy level of the threaded parts must also comply with ISO or GB standards. In addition, the spikes must pass a series of rigorous tests before leaving the factory, such as tensile tests, torque testi, testi utrujenosti itd. ., da bi zagotovili njihovo varnost in zanesljivost v železniškem sistemu .
Ti strogi standardi uspešnosti ne samo zagotavljajo, da se trni v veliki obremenitvi in močnimi vibracijskimi pogoji niso zlahka poškodovali, ampak tudi omogočajo, da med delom v železnici stabilno popravljajo tirnice, kar je ena od pomembnih zagotovil za varno delovanje železnice .
