Sand casting manganese steel kintu kirungi nnyo eky’okukola ebipimo ebinene-Scale steel castings. Ebintu ebinene- ebisuuliddwa ebyuma ebikoleddwa mu kyuma kya manganese birina ebirungi bingi ebika by’ebyuma ebirala bye bitalina, era bikolebwako ekyuma kya manganese. Ebintu ebinene ebisuuliddwa bisobola okukozesebwa mu mbeera ezimu enkambwe.
Ebirungi ebiri mu kukozesa ekyuma kya manganese okukola ebyuma ebinene okusingamu bibaamu ensonga ezo waggulu. Kkampuni bwe zigula ebyuma ebinene, kikulu nnyo okumanya ebintu bye balina okukozesa. Omutindo n’omutindo gw’ebyuma ebinene ebikoleddwa mu kyuma kya manganese bijja kuba birungi nnyo. Mu.
(1) ebyuma ebinene ebikoleddwa mu kyuma kya manganese birina obuziyiza obw’amaanyi ennyo obw’okukuba era bisobola okugumira okukosebwa okw’amaanyi;
(2) Okuziyiza okusikagana kw’ebyuma ebinene nabyo nsonga nkulu nnyo mu kusalawo omutindo, era okuziyiza okusika omuguwa kw’ebyuma ebinene ebikoleddwa mu kyuma kya manganese nakyo kirungi nnyo;
(3) Obukakanyavu obulungi y’emu ku mbeera ezeetaagisa ebyuma ebinene ebisuuliddwa okubeera ebisaanira embeera nnyingi enkambwe. Obugumu bw’ebyuma ebinene ebisuuliddwa ebikoleddwa mu kyuma kya manganese kirungi nnyo.
Omutindo gw’ekyuma ekisuuliddwa mu makanika gusinga ogw’ekyuma ekisuuliddwa, naye omulimu gwakyo ogw’okusuula gubi okusinga ogw’ekyuma ekisuuliddwa. Olw’okuba ekifo ekisaanuuka eky’ekyuma ekisuuliddwa kiri waggulu, ekyuma ekisaanuuse kyangu okufuuka omukka, amazzi g’ekyuma ekisaanuuse gaba mabi, ate okukendeera kuba kunene. Omuwendo gw’okukendeera kw’obungi guli 10-14%, ate linear shrinkage rate guli 1.8-2.5%. Okusobola okuziyiza obulema nga okusuula obutamala, okuggalwa ennyonta, okukendeera kw’ebituli n’okukendeera obuziba, enjatika n’okunywerera ku musenyu mu byuma ebisuuliddwa, ebipimo bya tekinologiya ebizibu okusinga ekyuma ekisuuliddwa birina okukolebwa
