Nruab nrab Linear Expansion Coefficient

Thermal expansion

Nyob rau hauv cov xwm txheej uas qhov nruab nrab linear expansion coefficient ncav cuag tus qauv, cov ntsiab lus ntawm npib tsib xee thiab cobalt raug tso cai rau deviate los ntawm ntau yam teev tseg hauv Table {{0}}. Cov ntsiab lus ntawm txhuas, magnesium, zirconium thiab titanium yuav tsum tsis txhob ntau tshaj 0.10 feem pua ​​​​txhua tus, thiab tag nrho cov nyiaj yuav tsum tsis pub tshaj 0.20 feem pua.

● Cov qauv ntsuas kev ua tau zoo rau kev nthuav dav coefficient thiab tsis tshua muaj qhov kub thiab txias microstructure stability tau teev tseg hauv 4J29 cov txheej txheem kev kho cua sov yog rhuab mus rau 900 degree ± 20 degree hauv hydrogen cua, khaws cia rau 1 teev, ces rhuab mus rau 1100 degree ± 20 degree, thiab khaws cia rau 15 feeb, nrog qhov kub tsis siab tshaj qhov txias kom qis dua 200 degree ntawm tus nqi ntawm 5 degree / min.

● 4J29 Ntau yam Specifications thiab Availability Ntau yam muaj xws li hlau, sawb, phaj, raj thiab bar.

● 4J29 Melting and Casting Process Melting in non-vacuum induction furnace, vacuum induction furnace or electric arc furnace.

● 4J29 daim ntawv thov txheej txheem cej luam thiab cov kev cai tshwj xeeb Cov hlau no yog Fe-Ni-Co nyuaj iav sealing alloy feem ntau siv hauv ntiaj teb. Nws tau siv rau lub sijhawm ntev hauv lub Hoobkas aviation nrog kev ua haujlwm ruaj khov. Nws yog tsuas yog siv rau iav sealing ntawm hluav taws xob lub tshuab nqus tsev cov khoom xws li tso cov raj, oscillator raj, ignition tubes, magnetrons, transistors, kaw plugs, relays, integrated circuit lead xov hlau, chassis, shells, brackets, thiab lwm yam. Nyob rau hauv daim ntawv thov, cov xaiv iav yuav tsum sib phim nrog cov expansion coefficient ntawm cov hlau. nruj me ntsis ntsuas nws cov ntaub so ntswg kub tsis tshua muaj kev ruaj ntseg raws li kev siv kub. Kev kho cua sov kom tsim nyog yuav tsum tau ua thaum lub sijhawm ua haujlwm kom ntseeg tau tias cov khoom muaj qhov zoo sib sib zog nqus nqus. Thaum siv forgings, lawv cov huab cua nruj yuav tsum tau xyuas kom nruj.
