Kodi muyenera kudziwa chiyani mukamagula njerwa zosokoneza?

Kodi muyenera kudziwa chiyani mukamagula njerwa zosokoneza? Kodi ndi zotengera zamoto zotani zomwe zimagwiritsidwa ntchito panjerwa? Kodi njerwa zotsutsa zingakwaniritse momwe zingagwiritsire ntchito? Kodi mungagule bwanji njerwa kuti mupeze zotsatira zabwino? Kuphatikiza momwe zinthu zilili, amafotokozera zakunyumba zotsutsa zomwe akuyenera kuzisamalira.

1. Malo a uvuni pogwiritsa ntchito njerwa zopangira

Malinga ndi kapangidwe ka ng’anjo, magwiridwe antchito ndi magwiridwe antchito a gawo lililonse la ng’anjo, njerwa zotsutsa zimasankhidwa kuti zikwaniritse zosankhidwa. Mwachitsanzo, akalowa ndi pansi pamiyeso yazitsulo zosiyanasiyana pansi pa mzere wa slag (monga ziwaya ndi malo owotchera) amachitidwa makamaka ndi mankhwala osungunuka a slag ndi chitsulo, kutsatiridwa ndi kupsinjika kwamafuta komwe kumayambitsidwa ndikusintha kwadzidzidzi kwanyengo. Zomangamanga nthawi zambiri zimasankha njerwa za magnesia ndi magnesia-chrome zotsutsana ndi slag. Pamwamba slag mzere angasankhe magnesia aluminiyamu njerwa, magnesia chrome njerwa kapena mkulu aluminiyamu refractory njerwa.

2. Onetsetsani magwiridwe antchito ndi moyo wonse wa ng’anjo

Monga poyatsira uvuni, kuyenera kutsimikizika kwa ntchito yake yonse komanso moyo wake wonse. Sinthani moyenera njerwa zosiyanasiyana zomwe zimagwiritsidwa ntchito m’malo osiyanasiyana m’ng’anjoyo. Mukazindikira madera osiyanasiyana m’ng’anjo ndi zida za gawo limodzi, pewani kuyanjana ndi kusungunuka kwa zinthu pakati pa njerwa zosiyanasiyana, ndikuonetsetsa kuti kutayika kwa gawo lirilonse kuli koyenera, kapena tengani njira zoyenera kuti muchepetse kutayika ndikuwonetsetsa moyo wonse wamoto.

3. Makhalidwe a njerwa zaumboni

Mukamagula njerwa, muyenera kudziwa bwino njerwa, monga kapangidwe ka njerwa, mawonekedwe ake ndi magwiridwe antchito a njerwa, komanso ngati zingakwaniritse zomwe zikuyembekezeredwa ngati ng’anjo, kuti zitheke khalani ndi mawonekedwe abwino a njerwa zokhazikitsira pansi. Mwachitsanzo, njerwa za silika zamauvuni a coke zimakhala zotentha kwambiri pansi pake ndipo zimatha kukana kukokoloka kwa asidi, koma kukana kwawo matenthedwe kumakhala kovuta ndipo kungagwiritsidwe ntchito pamakoma ogawa coke. Makhalidwe awo ofewa atha kugwiritsidwa ntchito m’malo otentha kwanthawi yayitali.

2. Makina opanga njerwa

Monga wogula njerwa, kuti mugule njerwa zomwe zimagwiritsidwa ntchito mobwerezabwereza, muyenera kudziwa index, kukula, magwiridwe antchito ndi zina zambiri za njerwa zotsutsa, ndikufunsani wopanga njerwa ngati angathe kupanga, ngati angathe kukumana ndi zofunikira, ndipo ngati njerwa zosanjidwazo zitha kukwaniritsa zofunikira Makhalidwe ndi zina, uku ndiye kukhulupirika kwakukulu kwa opanga njerwa.
