Simbi yakaurayiwaisimbi yakabviswa zvachose nekuwedzera kweajenti isati yakanda zvekuti hapazove nekushanduka kwegasi panguva yekusimba. Iyo inoratidzirwa nehupamhi hwepamusoro hwemakemikari homogeneity uye rusununguko kubva kune gasi porosities.

Semi-yakaurayiwa simbi inonyanya kuita deoxidized simbi, asi iyo kabhoni monoxide inosiya blowhole mhando porosity yakagoverwa mukati meingot. Iyo porosity inobvisa pombi inowanikwa musimbi yakaurayiwa uye inowedzera goho kusvika 90% nehuremu. Semi-yakaurayiwa simbi inowanzoshandiswa pakugadzira simbi ine kabhoni yemukati pakati pe0.15 ne0.25% kabhoni, nekuti yakakungurutswa, inovhara iyo porosity.

Rimmed simbi, inozivikanwawo sesimbi yekudhirowa yemhando yepamusoro, haina zvishoma kana isina deoxidizing agent yakawedzerwa pairi panguva yekukanda izvo zvinoita kuti kabhoni monoxide ishanduke nekukurumidza kubva muingot. Izvi zvinokonzeresa maburi madiki ari pamusoro ayo anozovharwa gare gare mukupisa kwekukungurutsira. Simbi yakawanda ine rimmed ine carbon content iri pasi pe0.25%, manganese content iri pasi pe0.6%, uye haina kusanganiswa nealuminium, silicon, uye titanium.Nekuda kwekusafanana kwezvinhu zvealloying hazvikurudzirwi kune zvikumbiro zvinopisa.
