Ntxiv nrog rau kev siv los ua degasser, nws yog xim hlau calcium feem ntau yog Ca-Pb thiab Ca-Zn alloys siv hauv kev tsim cov bearings.Tom qab ntawd peb tuaj yeem siv txoj kev siv hluav taws xob ncaj qha rau electrolyze thiab yaj Ca-Zn los tsim, uas yog, siv cov kua Pb cathode lossis kua Em cathode rau electrolyze thiab yaj CaCl2, kom cov cathode txheej ntawm cov hlau calcium pas nrig uas tshwm sim los ntawm cov cathode nto tuaj yeem diffuse, thiab cathode hlau Pb lossis Em Form Ca-Pb lossis Ca-Zn alloy, thiab tog rau hauv lub qhov dej uas cov hlau sib sau rau hauv qab ntawm lub tank electrolytic, thiab tom qab ntawd tsis tu ncua siv rab diav kom tshem tawm cov hlau los ntawm lub qhov tsub zuj zuj.
Thaum siv cov kua Pb lossis Em cathode rau electrolyze thiab yaj CaCl2, 20% KCl yog ntxiv rau cov electrolyte kom txo cov melting kub, yog li nws qhov kub thiab txias yog 750 ° C.Tom qab kev tsim tawm ntawm Ca-Pb thiab Ca-Em alloys tsis tu ncua, nws yuav tsum tau ntxiv tsis tu ncua raws li qhov ntim ntau lawm Pb lossis Em, siv txoj kev no los tsim Ca-Pb lossis Ca-Em alloy, tus nqi ntawm Ca hauv cov hlau tuaj yeem ncav cuag. 60 ~ 65%.Los ntawm electrolysis ntawm Pb + Ca thiab Em-Ca alloys, ncuav lawv mus rau hauv npua hlau pwm rau cam khwb cia ingots, ces ntxuav tawm cov electrolyte rau saum npoo ntawm cov alloy ingots nrog dej, thiab muab tso rau hauv cia tom qab ziab.Siv txoj kev no los tsim Ca-Pb thiab Ca-Em alloys muaj kev siv hluav taws xob tsawg, tsis siv cov khoom siv raw, thiab tus nqi qis.Nws yog txoj kev yooj yim tshaj plaws rau kev tsim Ca-Pb thiab Ca-Em alloys
