Zvakawanda sei zvaunoziva nezve mashandisirwo eanoramba achikanda muchina mukugadzira simbi yakakosha?

Inoramba ichikanda michina inozivikanwawo sesimbi yekukanda michina, inova yepamberi yekudhirowa yekukanda nzira. Yayo misimboti yekushanda ndeyekunyungudutsa simbi dzisiri-ferrous pasi pekupisa induction kudziyisa, ramba uchidzidira mune yakakosha simbi mold inonzi crystallizer, uye wozoburitsa iyo yakaomeswa (crusted) yekukanda. Imwe magumo ekamuri yekukanda inoshandiswa kuwana makanda ehurefu, chimiro, uye hurefu hwakananga.

Muchina unoenderera mberi wekukanda wakagadzirirwa kukanda mahwendefa alloy, mabara akatenderera, masikweya mabara, rectangular mabara, machubhu akatenderera, uye mamwe maumbirwo egoridhe, K-goridhe, sirivheri, uye mamwe simbi anokosha. Inoshandiswa zvakanyanya mukugadzira simbi, semi-yakapedza goridhe zvishongo, simbi inonyungudutsa zvidyarwa, simbi process processing zvidyarwa, masangano ekutsvagisa, marabhoritari, zvikoro, yakakosha simbi yekunyungudutsa uye mamwe maindasitiri. Kukwenenzvera kuburitsa uye mhando chinhu chinodiwa chemuchina wekugadzira uye kugadzirwa kwezvinhu zvesimbi, pamwe nekuvandudzwa kwemetalurgical indasitiri zvigadzirwa.

Inoenderera mberi yekukanda michina yakakamurwa kuita vacuum uye isiri vacuum, unoziva here? Kune zvakare mutsauko wakakura pakati pavo, uye ini ndichakuzivisa iwo zvakadzama kune iwe unotevera.

Chekutanga, pane chepamusoro muchina chimiro. Iyo vacuum chimiro inoda dhigirii yakakwira yekutsvaira muhumburu yekukanda. Uyezve, pombi yevacuum inoda kuwedzerwa. Non vacuum inoramba ichikanda michina haina izvi zviviri zvinodiwa.

Chechipiri, kubva pakuona kwekushanda. Vacuum inoda kushandiswa muchoto nechoto, izvo zvinoreva kuti simbi yechoto inoputirwa kamwe chete nguva imwe neimwe, uye mushure mekupedza mabasa ose ekudhirowa, chikamu chechipiri chekushanda chinoitwa zvakare. Iyi nzira yekuvhiya inononoka uye inonetsa. Iko kushanda kweasina vacuum michina inogona kuve nyore nekunyungudika panguva imwe chete, kutungamirira pasi, uye kuwedzera zvinhu.

Chetatu, mutsauko uripo pakati pezvigadzirwa zvekukanda uye zvigadzirwa zvevacuum ndeye yakaderera okisijeni yemukati, iyo yakakodzera kugadziridzwa kwechigadzirwa cheindasitiri, senge waya dzekubatanidza, zvinhu zvemagetsi, uye zvigadzirwa zvisina vacuum. Nekudaro, kana iyo okisijeni yemukati yakakwira kupfuura zvigadzirwa zvevacuum, density yechigadzirwa yakangofanana, zvichiita kuti ive iyo inofarirwa zvinhu zvekugadzira zvishongo zvine zvemhando yepamusoro zvinodiwa.

Chechina, kushandiswa kwegasi rekudzivirira kunoreva nitrogen kana argon gasi, uye imwe chete yadzo inogona kushandiswa. Basa guru nderokuderedza kurasikirwa kunokonzerwa nesimbi oxidation. Ose ari maviri mashini ekukanda vacuum uye asiri evacuum ekukanda michina ane ekudzivirira gasi maficha.
