Cina OEM custom baja karbon castings ku leungit investasi lilin casting naCNC precision machining. Sadia kelas tina baja karbon low, baja karbon sedeng mun baja karbon tinggi nurutkeun spésifikasi béda. perlakuan permukaan sadia: lukisan, Anodizing, Passivation, Electroplating, Séng-plating, Hot-Séng-Plating, Polishing, Electro-Polish, nikel-Plating, Blackening, Geomet, Zintek.
Aloi karbon nyaéta golongan alloy beusi-karbon kalawan langka unsur kimia lianna kayaning Si, Bungbulang, P jeung S. Numutkeun tingkat eusi karbon, baja karbon pikeun casting umumna dibagi kana baja karbon low, baja karbon sedeng jeung baja karbon tinggi. Baja karbon tuang sadaya nagara di dunya umumna digolongkeun dumasar kana kakuatanana, sareng sasmita anu cocog dirumuskeun. Dina suhu anu sarua, fluidity baja molten kalawan eusi karbon béda béda. Kusabab steels kalawan eusi karbon béda boga tingkat béda tina ngembangkeun dendrites. Beuki gede interval suhu zona kristalisasi (bédana suhu antara garis liquidus jeung garis solidus), beuki dimekarkeun kristal déndritik tina baja karbon, nyaeta, anu parah fluidity tina baja molten, nu ngakibatkeun kamampuhan baja molten ngeusian kapang nu.
Ngeunaan komposisi kimia baja karbon, iwal fosfor jeung walirang, teu aya larangan atawa ukur wates luhur dina unsur kimia lianna. Dina premis di luhur, komposisi kimia baja karbon tuang ditangtukeun ku foundry nurutkeun sipat mékanis diperlukeun.
Métode perlakuan panas tinacastings baja karbonbiasana annealing, normalizing atanapi normalizing + tempering. Pikeun sababaraha castings baja karbon tinggi, quenching na tempering ogé bisa dipaké, nyaeta, quenching + tempering suhu luhur, ku kituna pikeun ngaronjatkeun sipat mékanis komprehensif castings baja karbon. Castings baja karbon leutik bisa langsung quenched na tempered tina kaayaan salaku-tuang. Pikeun castings baja karbon skala badag atawa kompléks ngawangun, éta luyu pikeun ngalakonan quenching na tempering perlakuan sanggeus perlakuan normalizing.
