Hot Sale GB Standard Y12 Y20 Alloy Free-machining Steel Round pa
O elemene faʻaopoopoina i le uʻamea faʻatau fua e aofia ai S, Pb, Ca ma P. O latou galuega autu e faʻapea:
1. O le matafaioi a le sulfur
Sulfur fausia MnS inclusions ma Mn i uʻamea, lea e mafai ona faʻalavelaveina le faʻaauauina o le matrix, faʻafaigofie ona malepe tupe meataalo, ma faʻaitiitia le nofoaga faʻafesoʻotaʻi i le va o meataalo ma le meafaigaluega. E mafai fo'i e le sulfur ona fa'aitiitia fe'ese'esea'iga ma taofia ai le pipii atu o meataalo ile pito tipi. Ae ui i lea, o le i ai o le sulfur e mafai ona faʻavevelaina ai le uʻamea ma faʻafefeteina, o le mea lea e masani ona faʻatapulaʻaina le mea o loʻo i ai i le w (s) = 0.10% ~ 0.30%, ma e tatau ona faʻateleina le Mn e fetaui ma ia.
2. O le matafaioi o le taitai
O le faʻaopoopoga o le Pb e mafai ona faʻaleleia ai le tipiina o le sila. Talu ai e le faʻafefeteina le Pb i le ferrite i le uamea ma e le faʻapipiʻiina, o loʻo i ai i se tulaga saoloto ma faʻapipiʻiina ni vaega lelei (2 ~ 3μm) faʻasalalau tutusa i le fausaga matrix. Pe a oʻo atu le vevela i le taimi o le tipiina i le mea liusuavai o vaega Pb, o loʻo i totonu o se tulaga uʻamea ma avea ma "lubricant" i le va o le meafaigaluega ma le meataalo ma le va o le meafaigaluega ma le mea faigaluega, faʻaitiitia ai le faʻalavelave, vevela meafaigaluega, ma le ofuina. Ole aofa'i ole Pb fa'aopoopo o lo'o iai ile va ole w(Pb)=0.1%~0.35%.
3. Le matafaioi a le calcium
Ca e mafai ona fausia Ca ma Al silicate inclusions i uʻamea, lea e pipii i le meafaigaluega e fausia ai se ata manifinifi, i ai se aafiaga feeseeseaʻi-faaitiitia, ma puipuia le ofuina meafaigaluega. Ole aofaiga ole Ca faaopoopo e masani lava w(Ca)=0.001%~0.005%.
4. Le matafaioi a le phosphorus
E fa'aopoopoina le P i le u'amea o lo'o i ai le u'amea e fa'amama fua i le ferrite, ma mafua ai le fa'amalosia ma le fa'aleagaina e fa'aleleia atili ai lona fa'atinoga o le tipiina. Ina ia puipuia le "malulu malulu", w (P) ua faʻamaonia e ≤0.15%.
O le faʻaopoopoga o nei elemene e mafai foi ona faʻaleleia atili le tulaga maualuga o le mea faigaluega ma faʻalauteleina le ola tautua o le meafaigaluega.
Afai e te manaʻomia nisi faʻamatalaga auʻiliʻili, e fautuaina e faʻafesoʻotaʻi matou mo faʻamatalaga auiliili e uiga i faʻamatalaga faʻapitoa ma faʻaogaina o nei paʻu uamea.
