Umbhobho wensimbi ochanekileyo ochanekileyo ngumbhobho obandayo okanye oshushu-oshushu emva kokunyangwa kombhobho wensimbi ochanekileyo. Njengombhobho ochanekileyo wentsimbi ongenamthungo ngaphakathi nangaphandle kodonga lwe-non-oxidized layer yombhobho wentsimbi echanekileyo, ukumelana noxinzelelo oluphezulu ngaphandle kokuvuza, ukuchaneka okuphezulu, ukugqiba okuphezulu, ukugoba okubandayo, ukuvutha, ukubethelwa ngaphandle kokuqhekeka, njl. esetyenziselwa ukuvelisa i-pneumatic okanye i-hydraulic components Iimveliso, ezinjengeesilinda okanye iisilinda, zenziwe ngeetyhubhu ezingenamthungo. Umbhobho wensimbi ochanekileyo ongenamthungo wekhemikhali ye-carbon C, i-silicon Si, i-manganese Mn, isulfure S, i-phosphorus P, i-chromium Cr.

Umahluko phakathi kombhobho wentsimbi echanekileyo kunye nombhobho wentsimbi ongenamthungo

I-1, iimpawu eziphambili zombhobho wensimbi ongenamthungo akukho mthungo we-welding, unokumelana noxinzelelo olukhulu. Imveliso ingaba rhabaxa kakhulu njenge-cast okanye iindawo ezitsalwa ngokubanda.

I-2, umbhobho wensimbi ochanekileyo kwiminyaka yamuva kukho iimveliso, ngokukodwa ngaphakathi komngxuma, ubungakanani bodonga lwangaphandle lunokunyamezela okungqongqo kunye noburhabaxa.

Iimpawu zetyhubhu yentsimbi echanekileyo engenamthungo

1. Idayimitha yangaphandle encinci.

2. Ukuchaneka okuphezulu kunokwenza imveliso encinci yebhetshi.

3. Ukutsalwa okubandayo kugqityiwe ukuchaneka okuphezulu, umgangatho omhle womphezulu.

4. Indawo ye-Tube cross-sectional inzima ngakumbi.

5. Ukusebenza kombhobho kungcono, isinyithi esixineneyo.
