Intengiso eshushu i-GB Standard Y12 Y20 Alloy Free-machining Steel Round bar

Izinto ezongeziweyo kwintsimbi yokusika mahhala ziquka i-S, i-Pb, i-Ca kunye ne-P. Imisebenzi yabo ephambili yile ilandelayo:
1. Indima yesulfure
I-Sulfur ifom ye-MnS inclusions kunye ne-Mn ngensimbi, enokuphazamisa ukuqhubeka kwe-matrix, yenza ii-chips zibe lula ukuphuka, kunye nokunciphisa indawo yoqhagamshelwano phakathi kwee-chips kunye nesixhobo. Isulfure inokunciphisa ukungqubana kwaye ithintele iichips ukuba zingabambeleli kumda wokusika. Nangona kunjalo, ubukho besulfure bunokwenza intsimbi ibe shushu kwaye ibe ne-brittle, ngoko umxholo wesulfure ukhawulelwe ngokubanzi kuluhlu lwe-w (s) = 0.10% ~ 0.30%, kwaye umxholo we-Mn kufuneka unyuswe ngokufanelekileyo ukuwufanisa.
2. Indima yelothe
Ukongezwa kwePb kunokuphucula ukusebenza kwentsimbi. Ekubeni i-Pb ayinyibiliki kwi-ferrite ngentsimbi kwaye ayifaki iikhompawundi, ikwimeko ekhululekile kwaye yenza iincinci ezintle (2 ~ 3μm) zihanjiswe ngokufanayo kwisakhiwo se-matrix. Xa ubushushu obuveliswe ngexesha lenkqubo yokusika bufikelela kwindawo yokunyibilika kwamasuntswana e-Pb, ikwimeko etyhidiweyo kwaye iba "yi-lubricant" phakathi kwesixhobo kunye neetshiphusi kunye naphakathi kwesixhobo kunye nendawo yokusebenza, ukunciphisa i-friction factor, ubushushu besixhobo, kunye nokunxiba. Isixa sePb esongeziweyo sikuluhlu lwe-w(Pb)=0.1%~0.35%.
3. Indima ye-calcium
I-Ca ingenza i-Ca kunye ne-Al silicate inclusions kwintsimbi, ehambelana nesixhobo sokwenza ifilimu encinci, ibe nefuthe lokunciphisa i-friction, kunye nokuthintela ukugqoka izixhobo. Umyinge we-Ca edityanisiweyo ngokubanzi ngu-w(Ca)=0.001%~0.005%.
4. Indima ye-phosphorus
I-P yongezwa kwi-sulfure-equkethe insimbi yokuqhawula yamahhala ukuyichitha kwi-ferrite, ebangela ukuqiniswa kunye ne-embrittlement ukuphucula ukusebenza kwayo kokusika. Ukuze kuthintelwe "i-brittleness ebandayo", i-w(P) ichazwe ukuba yi-≤0.15%.
Ukongezwa kwezi zinto kunokuphucula umgangatho wendawo yokusebenza kunye nokwandisa ubomi benkonzo yesixhobo.

Ukuba ufuna ulwazi oluthe kratya, kuyacetyiswa ukuba uqhagamshelane nathi ngolwazi oluthe kratya malunga neenkcukacha ezithile kunye nokusetyenziswa kwezi ntsimbi zentsimbi.
