12L14 Yemahara-Kucheka Simbi Bar

A simbi ine yakakwira kupfuura yakajairwa zvirimo zvesarufa nephosphorus zvakagadzirirwa kugadzirwa kwezvikamu zveyepamusoro-kumhanya otomatiki uye semiautomatic muchina maturusi. Simbi yemahara-yekucheka inogadzirwa nenzira yetsvimbo, uye ine 0.08-0.45 muzana kabhoni, 0.15-0.35 muzana nesilicon, 0.6-1.55 muzana manganese, 0.08-0.30 muzana sarufa, uye 0.05-0.16 muzana phosphorus. Iyo yakakwira sulfur yemukati inotungamira mukuumbwa kweiyo inclusions (semuenzaniso, manganese sulfide) yakaraswa pamwe chete nezviyo. Izvi zvinosanganisirwa zvinofambisa kuveura uye zvinosimudzira kukuya uye nyore chip kugadzirwa. Nezvinangwa izvi, simbi yemahara-yekucheka dzimwe nguva inosanganiswa nemutobvu uye tellurium.

12L14 imhando ye resulfurized uye rephosphorized kabhoni simbi yemahara-kucheka uye machining application. Simbi yezvimiro (otomatiki Simbi) ine yakanakisa machinability uye yakaderera simba nekuda kweiyo alloying zvinhu seSulfur uye Lead, izvo zvinogona kuderedza kucheka kuramba uye kugadzirisa kupedzisa uye kurongeka kwezvikamu zvemuchina. 12L14 simbi yakashandiswa zvakanyanya mukugadzirwa kweiyo chaiyo chiridzwa zvikamu, zvikamu zvemotokari uye zvikamu zvakakosha zvemhando dzakasiyana dzemakina, mashandisirwo akajairika anosanganisira bushings, shafts, kuisa, couplings, fittings uye nezvimwe.
