Qhov sib txawv ntawm cov hlau hlau thiab hlau hlau feem ntau yog nyob rau hauv lawv cov ntaub ntawv, kev siv, thiab kev tsim khoom:
1. Khoom siv: Hlau xaim: Feem ntau yog ua los ntawm siab - carbon steel, nws dhau mus siab - kev kho kub thiab deg hardening, ua rau siab hardness thiab lub zog. Hlau hlau: Feem ntau ua los ntawm qis- carbon steel, nws feem ntau yog galvanized los txhim kho nws cov xeb tiv thaiv.
2. Daim ntaub ntawv: Hlau xaim: Vim nws lub zog siab thiab hardness, nws feem ntau yog siv rau hauv kev tsim cov khoom xws li cov hlua, hlua hlua, thiab cov hlua khi hlua khi, nrog rau cov khoom siv ntxiv rau kev tsim kho vaj tse xws li vaj tse, txuas hniav, thiab txoj kev. Nws tseem tuaj yeem siv los tsim ntau yam khoom siv hlau, xws li hlau mesh thiab txhuam hlau. Hlau hlau: Vim nws zoo heev yooj thiab xeb kuj, nws yog dav siv nyob rau hauv ua teb, handicrafts, fencing, thiab bundling.
3. Cov txheej txheem tsim khoom: Hlau xaim: Cov txheej txheem ntau lawm feem ntau suav nrog steelmaking, dov, thiab kos duab kom ua tiav qhov xav tau loj thiab cov khoom. Hlau hlau: Ntau lawm kuj yooj yim, feem ntau yog dov los yog kos qis - carbon steel hlau thiab ces galvanizing nws.
