Hot Sale GB Standard Y12 Y20 Alloy Yemahara-machining Steel Round bar

Zvinhu zvinowedzerwa kusimbi yekucheka-mahara zvinosanganisira S, Pb, Ca uye P. Mabasa avo makuru ndeaya anotevera:
1. Basa resarufa
Sulfur inoumba MnS inclusions neMn musimbi, iyo inogona kukanganisa kuenderera kwematrix, kuita kuti machipisi ave nyore kutyora, uye kuderedza nzvimbo yekubatana pakati pemachipisi nechishandiso. Sarufa inogona zvakare kuderedza kupokana uye kudzivirira machipisi kuti asanamatira kumucheto wekucheka. Nekudaro, kuvepo kwesarufa kunogona kuita kuti simbi ipise uye iite brittle, saka iyo sulfur yemukati inowanzoganhurwa kune huwandu hwe (s) = 0.10% ~ 0.30%, uye iyo Mn yemukati inofanirwa kuwedzerwa zvakakodzera kuti ienderane nayo.
2. Basa remutobvu
Kuwedzerwa kwePb kunogona kuvandudza kucheka kwesimbi. Sezvo Pb isinganyungudike kuita ferrite musimbi uye isingagadziri makomisheni, iri munzvimbo yakasununguka uye inoumba zvidimbu zvakanaka (2 ~ 3μm) zvakagoverwa zvakafanana muchimiro chematrix. Kana kupisa kunogadzirwa panguva yekucheka kunosvika pakunyunguduka kwePb zvimedu, inenge yakanyungudutswa uye inova "lubricant" pakati pechishandiso nemachipisi uye pakati pechishandiso nenzvimbo yebasa, kuderedza friction factor. tembiricha yemidziyo, nekupfeka. Huwandu hwePb hwakawedzerwa huri muchikamu che w(Pb)=0.1%~0.35%.
3. Basa re calcium
Ca inogona kuumba Ca uye Al silicate inclusions musimbi, iyo inonamatira kune chishandiso kugadzira firimu rakatetepa, kuve nekukwenya-kuderedza mhedzisiro, uye kudzivirira kupfeka chishandiso. Huwandu hweCa inowedzerwa kazhinji w(Ca)=0.001%~0.005%.
4. Basa re phosphorus
P inowedzerwa kune sulfuri-ine simbi isina kusununguka kuti iparadze iyo mu ferrite, inokonzera kusimba uye embrittlement kuvandudza kushanda kwayo kwekucheka. Kuti udzivise "kutonhora brittleness", w(P) inotsanangurwa kuve ≤0.15%.
Kuwedzerwa kwezvinhu izvi kunogonawo kuvandudza hutano hwepamusoro hwebasa rekushanda uye kuwedzera hupenyu hwebasa rechombo.

Kana iwe uchida rumwe ruzivo rwakadzama, zvinokurudzirwa kuti ubvunze isu kuti uwane ruzivo rwakadzama pane yakatarwa uye mashandisirwo eaya alloy simbi simbi.
