Qhov loj me:
Peb muab cov khoom nyob rau hauv cov duab ntawm cov hlau, tiaj tus hlau, strip.Peb kuj tuaj yeem ua cov khoom siv raws li cov neeg siv khoom thov.
Bright, annealed, mos xaim-0.025mm ~ 5mm
Acid pickeling dawb hlau: 1.8mm ~ 10mm
Oxidized hlau: 0.6mm ~ 10mm
Flat hlau: thickness 0.05mm ~ 1.0mm, dav 0.5mm ~ 5.0mm
Txheej txheem:
Hlau: Cov khoom npaj → melting → re-melting → forging → kub dov → kho cua sov → kev kho deg → kos duab (dov) → tiav kev kho cua sov → tshuaj xyuas → pob → warehouse
Khoom nta:
1) Zoo heev los tiv thaiv oxidation thiab txhua yam muaj zog ntawm qhov kub thiab txias;
2) High resistivity thiab qis kub coefficient ntawm kuj;
3) Zoo heev reelability thiab tsim kev ua tau zoo;
4) Zoo heev vuam kev ua tau zoo
Kev siv txhua qib:
NiCr 80/20: nyob rau hauv braking resistors, industries furnaces, ca hlau, ironing machines, dej rhaub, yas molding tuag, soldering hlau, hlau sheathed tubular ntsiab thiab cartridge ntsiab.
NiCr 70/30: nyob rau hauv industrial furnaces. zoo haum rau txo cov cua, raws li nws tsis raug rau 'ntsuab rot'.
NiCr 60/15: nyob rau hauv braking resistors, industries furnaces, kub daim hlau, grills, toaster cub thiab cia tso cua sov. Rau cov coils tshem tawm hauv cov cua sov hauv cov khaub ncaws ziab khaub ncaws, kiv cua cua sov, tes tshuab ziab khaub ncaws.
NiCr 35/20: nyob rau hauv braking resistors, industrial furnaces.In hmo ntuj cia tso cua sov, convection heaters, hnyav luag hauj lwm rheostats thiab kiv cua tso cua sov. Rau cua sov cables thiab hlua cua sov hauv defrosting thiab de-icing hais, hluav taws xob pam vov thiab pads, lub rooj zaum tsheb, baseboard heaters thiab floorheater.
NiCr 30/20: nyob rau hauv cov khoom kub kub, qhib coil cua sov hauv HVAC systems, hmo ntuj tso cua sov, convection heaters, hnyav luag hauj lwm rheostats thiab kiv cua heaters.Rau cov cua sov cables thiab hlua cua sov nyob rau hauv defrosting thiab de-icing ntsiab, hluav taws xob pam vov thiab pads, tsheb rooj, baseboard heaters.
