Qhov loj me ntawm Nickel alloy hlau:

Peb muab cov khoom lag luam hauv cov duab ntawm cov hlau, cov hlau tiaj tus, strip. Peb kuj tuaj yeem ua cov khoom siv raws li cov neeg siv khoom thov.

Hlau ci thiab dawb - 0.025mm ~ 3mm

Hlau pickling: 1.8mm ~ 10mm

Hlau oxidized: 0.6mm ~ 10mm

Hlau tiaj tus: tuab 0.05mm ~ 1.0mm, dav 0.5mm ~ 5.0mm

Txheej Txheem:

Hlau: Khoom siv npaj → yaj → rov yaj → forging → kub dov → kho cua sov → kho qhov chaw → kos duab (dov) → tiav kho cua sov → tshuaj xyuas → pob → tsev rau khoom

Cov yam ntxwv ntawm nichrome hlau:

1) Zoo heev tiv thaiv oxidation thiab lub zog kho tshuab ntawm qhov kub siab;

2) Kev tiv taus siab thiab coefficient kub tsawg ntawm kev tiv taus;

3) Kev rov ua dua zoo heev thiab kev ua tau zoo;

4) Kev ua tau zoo heev ntawm kev vuam
