Seamless zitsulo chitoliro nkhani zambiri

27 nsimachubu opanda zitsulo, ie27SiMn machubu achitsulo opanda msoko, ndi chimodzi mwazinthu zopangira machubu achitsulo opanda msoko.Mpweya wa kaboni uli pakati pa 0.24 ndi 0.32%.Mzere umodzi wa simn ndi chifukwa cha zinthu zisanu (carbon C, silicon Si ndi manganese).Mu Mn, phosphorous P, ndi sulfure S, zomwe zili mu silicomanganese ndi pafupifupi 1.10 mpaka 1.40%.Chitoliro chopanda msoko cha 27simn ndichoyenera kupangira magetsi, chowotchera, mafakitale amafuta, magalimoto, zida za sitima.
27simn yopanda chitsulo chiphunzitso kulemera kwake chilinganizo chopanda chitsulo chubu pa mita kulemera W = 0.02466 * S(DS)
Tanthauzo la Chizindikiro: D = M'mimba mwake wakunja S = Chitsanzo chowerengera makulidwe a khoma: Kwa chitoliro chachitsulo chosasunthika chokhala ndi mainchesi akunja a 60mm ndi makulidwe a khoma la 4mm, werengerani kulemera kwa mita.
Kulemera kwa mita =0.02466*4*(60-4)=5.52Kg
