Q1: Dab tsi yog Ni80cr20 (Nichrome 80/20) thiab nws cov khoom tseem ceeb?
A1: Ni80Crr20, tseem hu ua Nichrome 80/20, yog ib npib tsib xee {} chromium alloy muaj kwv yees li 80% npib tsib xee thiab 20% chromium. Nws yog heev resistant rau oxidation thiab corrosion thiab tswj hluav taws xob ruaj khov, ua rau nws zoo tagnrho rau cov ntawv thov cua sov.
Q2: Cov ntawv thov ntawm Ni80Cr20 yog dab tsi?
A2: NI80CR20 cov ntawv tau siv nyob rau hauv cov hluav taws xob cua sov cov ntsiab lus, cua sov cov xov hlau, cov xov hlau, thiab cua sov kev muaj cua sov. Lawv tsim nyog rau cov ntawv thov xws li kilns, ncu, chav kuaj kom sov, thiab cov cua sov coils.
Q3: Cov dej kub ntau npaum li cas ni80cr20 wallstand?
A3: NI80CR20 ua cov kev kub ntxhov ntawm qhov kub thiab txias txog 1200℃(2190℃f) hauv huab cua. Nws tiv thaiv oxidation txawm nyob ntev - kub nthuav tawm, uas ua rau nws zoo tagnrho rau cov cua sov thiab kev lag luam ncu.
Q4: Dab tsi yog cov neeg kho tshuab thiab hluav taws xob ntawm ni80cr20?
A4: Cov khoom raug xws li:
Tensile lub zog: 550-750 MPa
Elongation: 15-40%
Ntom ntom: ~ 8.4 g / cm³
Hluav Taws Xob Tiv Thaiv: ~ 1.10 ω · ag² / m
Cov khoom no muab cov ntsuas hluav taws xob zoo tshaj plaws thiab kev ruaj khov hluav taws xob ua rau cov cua sov.
Q5: Ni80cr20 cov ntawv yuav ua tiav li cas lossis fabricated?
A5: NI80CR20 cov ntawv tuaj yeem txiav, stamped, lossis khoov rau hauv ntau cov duab rau cov khoom cua kub. Lawv tuaj yeem muab welded siv qhov tsim nyog siab - cov technique. Annealing yog qee zaum siv los txhim kho kev sib luag ua ntej sib sau ua ke. Cov ntawv txheeb yog feem ntau muab rau hauv dov thiab annealed mob los xyuas kom ntseeg tau cov khoom siv uas tsis muaj chav nyob.
