Qhov zoo ntawm Annealed Hlau

1. Dub hlau hlau muaj zog elasticity thiab zoo saj zawg zog, thiab nws softness yuav raug kho thaum lub sij hawm annealing. Nws yog ua los ntawm cov hlau hlau thiab yog siv rau kev sib txuas thiab khi hauv kev tsim kho kev lag luam. Cov xov loj loj yog 5 # -38 # (nrog rau txoj kab uas hla ntawm 0.17-4.5mm), uas yog softer, softer, thiab ntau dua li cov xov dub zoo tib yam, nrog txawm tias chromaticity.
2. Kev tsim cov hlau hlau feem ntau siv cov txheej txheem kos duab hlau thiab kev kho galvanizing. Xyoo 1976, cov thev naus laus zis tshiab xws li electrolytic pickling, high-pressure tu, thiab daim npav hluav taws xob ziab yog thawj zaug hauv Suav teb rau kev tsim cov kab txuas ntxiv. Cov txheej txheem txuas ntxiv tau hloov pauv los ntawm kev ua haujlwm tsis tu ncua mus rau kev tsim khoom tas mus li, ua rau tsis muaj zog siv zog thiab txo qis kev siv hlau. Nyob rau lub sijhawm ntawd, cov tuam txhab tsim khoom lag luam tau tsim cov xaim hlau xws li cov hlua hlau, cov hlua, lub kaus mom, cov hlua, thiab cov tsheb kauj vab eeb. Nyob rau xyoo 1980, kub dip qis-carbon steel hlau, kiv cua network hlau, carbon qauv hlau, thiab txaj saum npoo hlau tau ua tiav siv rau stapling.
