YAkaderera CARBON SIMBA GRANAL ADVANTAGE COST
• Kuita pamusoro pe20% kupikisa high carbon shots
• Kusakara kushoma kwemuchina nemidziyo nekuda kwekunyanya kunyura kwesimba mukukanganisa muzvidimbu.
• Zvimedu zvisina kukanganisa zvinokonzerwa nekupisa kwekushisa, fractures kana micro cracks
KUBATSIRA ZVINHU
• Kuderedza upfu
• Bainitic microstructure inovimbisa kuti haizoputsika munguva yehupenyu hunobatsira
ZVINHU ZVAKAWANDA
Chimiro cheyakaderera kabhoni simbi yakapfurwa yakafanana neye spherical.Kuvapo kushoma kweakareba, akaremara zvimedu zvine pores, slag kana tsvina zvinogoneka.
Izvi hazvikanganisi kuita kwepfuti, inogona kusimbiswa nekuyera kuita kwayo pamushini.
HARDNESS
Iyo bainitic microstructure inovimbisa yakakwira mwero wekuoma.90% yezvikamu zviri pakati pe40 - 50 Rockwell C.
Iyo yakaderera kabhoni muyero ine manganese inovimbisa hupenyu hurefu hunobatsira hwezvikamu, nokudaro kuvandudza kuchena kwezvidimbu, sezvo nebasa remakanika vanowedzera kuoma kwavo.
Simba rekuputika kwepfuti rinotorwa zvakanyanya nezvikamu, nokudaro kuderedza kupera kwemuchina.
CARBON GRANULATION, KUNYANYA KUNYANYA
Iko kushandiswa kweiyo yakaderera kabhoni simbi kupfura ine chiyero chemichina ine turbines e2500 kusvika 3000 RPM uye kumhanya kwe80 M / S.
Kune michina mitsva inoshandisa 3600 RPM turbines uye kumhanya kwe110 M / S, izvi zvinodiwa kuti uwedzere kubereka.
