Hlau ntsia hlau, raws li lub npe implies, yog hlau ntsia hlau. Lawv yog ua los ntawm carbon steel. Tom qab annealing, quenching thiab lwm yam kev kho mob, lawv kuj yog ib qho nyuaj thiab tuaj yeem yooj yim tsav mus rau hauv cov pob zeb ua vaj tse. Txawm li cas los xij, yog tias qhov zoo ntawm cov hlau tsis yog raws li tus qauv, lossis cov phab ntsa pob zeb nyuaj, cov ntsia hlau steel yuav tsis raug tsav mus rau hauv nws. Nyob rau lub sijhawm no, koj tuaj yeem hloov cov ntsia hlau nyuaj rau cov ntsia hlau, lossis siv cov cuab yeej cuam tshuam, Phab ntsa ntsaws, ntsia hlau phom thiab lwm yam cuab yeej los daws qhov teeb meem. Cia peb kawm txog yuav ua li cas yog tias cov ntsia hlau cement tsis tuaj yeem nkag mus rau hauv pob zeb.
Kev siv cov ntsia hlau feem ntau yog tsav lawv mus rau hauv phab ntsa. Qee cov ntsia hlau zoo tib yam yuav tsis haum rau hauv cov phab ntsa pob zeb, yog li cov ntsia hlau puas tuaj yeem tsav mus rau hauv cov pob zeb ua vaj tse? Feem ntau hais lus, cov ntsia hlau steel yog qhov nyuaj dua li cov ntsia hlau zoo tib yam vim tias lawv tau ua los ntawm cov hlau thiab tau kho nrog 45 lossis 60 steel hlau kos duab, annealing, thiab quenching, ua rau muaj kev nyuaj siab dua. Rau cov phab ntsa zoo tib yam, cov ntsia hlau tuaj yeem muab tso nrog cov cuab yeej.
Txawm li cas los xij, nws yuav tsum raug sau tseg tias qee cov ntsia hlau hlau yuav muaj cov khoom siv tsis zoo lossis cov txheej txheem, lossis yog tias cov pob zeb muaj zog siab, cov rau tes yuav tsis tuaj yeem nkag mus. Yog li yuav ua li cas yog tias cov ntsia hlau tsis tuaj yeem nkag mus rau hauv pob zeb?
Muaj ob lub laj thawj tseem ceeb vim li cas cov ntsia hlau cement tsis tuaj yeem nkag mus rau pob zeb. Ib qho yog qhov zoo ntawm cov ntsia hlau steel, thiab lwm qhov yog tias cov phab ntsa pob zeb yog qhov nyuaj. Txoj kev kho mob yog raws li nram no:
1. Yog tias nws yog qhov teeb meem zoo nrog cov ntsia hlau hlau, nws yog qhov yooj yim los hloov lawv nrog cov khoom zoo.
2. Yog tias nws yog qhov teeb meem ntawm cov pob zeb ua kom muaj zog, koj tuaj yeem siv qhov kev sib tsoo thiab phab ntsa ntsaws los pab ntsia thawv cov cement steel ntsia hlau rau hauv phab ntsa, lossis siv rab phom ntsia hlau los daws nws. Yog tias nws ua tsis tau, koj tuaj yeem thov cov neeg ua haujlwm tshwj xeeb los pab daws nws.
Yog tias koj xav tau cov khoom lag luam zoo fastener, thov hu rau peb.
