Binary alloy inoumbwa nesilicon uye calcium ndeyechikamu cheferroalloys.Zvikamu zvaro zvikuru isilicon uye calcium, uye inewo tsvina yakaita sesimbi, aruminiyamu, kabhoni, sarufa uye phosphorus muhuwandu hwakasiyana.Muindasitiri yesimbi uye simbi, inoshandiswa se calcium additive, deoxidizer, desulfurizer uye denaturant kune isiri-metallic inclusions.Inoshandiswa seinoculant uye denaturant muindasitiri yesimbi yakakandwa.
Kushandisa:
As compound deoxidizer (deoxidization, desulphurization and degassing) Inoshandiswa mukugadzira simbi, alloy smelting.Seinoculant, inoshandiswawo mukugadzira kugadzirwa.
Chimiro chemuviri
Chikamu checa-si chine grey chakajeka icho chaionekwa nechimiro chezviyo zviri pachena.Bundu, zviyo uye upfu.
Package:
kambani yedu inogona kupa akasiyana akatsanangurwa chimiro chezviyo zvinoenderana nezvido zvemushandisi, izvo zvakaputirwa nemachira epurasitiki uye bhegi retani.

Kumwe kusvibiswa kunotsanangurwa maererano nezvinangwa zvakasiyana.Mukuwedzera, pahwaro hwesilicon-calcium alloys, zvimwe zvinhu zvinowedzerwa kuumba ternary kana multi-element composite alloys.Zvakadai seSi-Ca-Al;Si-Ca-Mn;Si-Ca-Ba, nezvimwewo, inoshandiswa se deoxidizer, desulfurizer, denitrification agent uye alloying agent musimbi nesimbi metallurgy.
Sezvo calcium ine hukama hwakasimba neokisijeni, sulfuri, hydrogen, nitrogen uye kabhoni musimbi yakanyungudutswa, silicon-calcium alloys inonyanya kushandiswa deoxidation, degassing uye kugadzirisa sarufa musimbi yakanyungudutswa.Calcium silicon inogadzira yakasimba exothermic mhedzisiro kana yawedzerwa kusimbi yakanyungudutswa.Calcium inoshanduka kuita karusiyamu mhute musimbi yakanyungudutswa, ine simba rinonyandura pasimbi yakanyungudutswa uye inobatsira pakuyangarara kwezvinhu zvisiri zvesimbi.Mushure mokunge silicon-calcium alloy yakasvibiswa, kwete-metallic inclusions ine zvidimbu zvakakura uye zviri nyore kutenderera zvinogadzirwa, uye chimiro uye maitiro e-non-metallic inclusions anochinjwa zvakare.Naizvozvo, silicon-calcium alloy inoshandiswa kugadzira simbi yakachena, simbi yemhando yepamusoro ine yakaderera okisijeni nesarufa zvirimo, uye yakakosha simbi inoshanda ine yakanyanya kuderera okisijeni nesarufa.Kuwedzerwa kwesilicon-calcium alloy kunogona kubvisa nodulation yesimbi nealuminium seyekupedzisira deoxidizer pa ladle nozzle, uye kuvhara kwemuromo we tundish yekuramba ichikanda |kugadzira iron.Mune tekinoroji yekunatsa kunze kwechoto chesimbi, silicon-calcium poda kana core wire inoshandiswa deoxidation uye desulfurization kuderedza zvirimo zveokisijeni nesarufa musimbi kusvika padanho rakaderera;inogona zvakare kudzora chimiro che sulfide musimbi uye kuvandudza mwero wekushandiswa kwecalcium.Mukugadzirwa kwesimbi yakakandwa, kuwedzera kune deoxidation uye kucheneswa, silicon-calcium alloy inoitawo inoculating basa, iyo inobatsira kuumba yakanaka-grained kana spherical graphite;inoita kuti graphite mune grey cast iron igovane zvakaenzana, inoderedza maitiro ekuchena;uye inogona kuwedzera silicon uye desulfurize, Kuvandudza cast iron quality.
