Nzira dzekuvandudza kushanda kwegasi kuvhuvhuta pasi peladle

DW series slit type inofema zvidhinha

Isu takaongorora maitiro ekuputira argon pazasi peladhi uye zvinodiwa zvezvidhinha zvinofema. Ichi chinyorwa chinotarisa nzira dzekuvandudza kushanda kwegasi kuvhuvhuta pazasi peladhi.

1. Sarudza zviri nani zvidhinha zvinofema

Kupokana kwekuora uye kushorwa kwevhu kwezvidhinha zvinofema hazviparadzaniswe nemhedzisiro yekuvhuvhuta kwepasi. Izvo zvakadzidzwa kubva mukuita kuti mushure mekushandiswa kwenguva refu, zvidhinha zvechinyakare-zvidhinha zvinopinda mumhepo zvichavharwa nesimbi yakatsemuka kupinda mukati uye kuvaka-slag pazvidhinha zvinopinda mumhepo. Panguva ino, kuvhuvhuta-kuvhurika kwemhepo-inopindirwa zvidhinha uye kuvhuvhuta-kuburikidza mwero pazasi peladhi zvakangooma kuzadzisa zvinodiwa neladle metallurgy.

Kusarudza zvidhinha zvinopinda nemhepo zvine high thermal shock resistance, permeability resistance and erosion resistance ndiyo nhanho yekutanga yekuvandudza kuvhuvhuta kwepasi kweladle.

Kutsemuka kwehupamhi, iyo geometry ye slit, uye kunyorova kweiyo ventilating core material kusimbi yakanyungudutswa inokanganisawo kupinda kwechidhinha chinofema. Naizvozvo, kana hupenyu hurefu huchidikanwa, iyo isingapindiki yekufemesa zvidhinha Iva sarudzo iri nani.

2. Sarudza yakakodzera pasi kuvhuvhuta gasi pressure process parameters

Zvinoenderana nedata, iyo yakaderera yepasi inovhuvhuta gasi kudzvanywa yakaenzana nehuwandu hwekumanikidza gasi pamusoro pemvura, kurasikirwa kwekumanikidzwa kwepombi yekupa gasi, iyo yakawedzera kudzvanywa inoumbwa nemabhubhu, uye static kudzvanywa kwesimbi yakanyungudutswa uye. iyo slag layer.

Kana iyo yepasi inovhuvhuta gasi dhizaini iri diki, mabhuru anozonetsa kuumba kana kubvongodza kuchave kushoma.

Kana gasi rinofuridza pasi rakanyanya kukwira, zvinokonzeresa kudzikira kwekuunganidzwa kwebubble uye kupararira, kudzikira kwekushandiswa kwegasi rinoputika uye kuzunguza kwakanyanya kwesimbi yakanyungudutswa, izvo zvinoita kuti simbi yakanyungudutswa iwande kusangana nemhepo panguva yekubhururuka. , zvichikonzera kuwedzera kwechipiri oxidation yesimbi yakanyungudutswa uye kuderera kukuru kwekushisa.

Hunhu hwemagiredhi akasiyana esimbi hunosarudza maitiro akasiyana ekugadzira simbi. Iyo yakanyanya kukodzera pasi kuvhuvhuta kumanikidza ndeyekusangana nemaitiro ekugadzira simbi zvinodikanwa zvesimba rekuzunguza gasi, kuitira kuti simbi yemvura yesimbi inokungurukira mukati mechinhanho chakakodzera, uye zvinosanganisirwa zvichayangarara kusvika padanho rakakura. Panguva imwecheteyo, inogona kutamba zvakanyanya basa rekuvhara ladle mumiriri, zviri nani kuve nechokwadi chekuti iyo inovhara inobata iyo inclusions inotakurwa nemabhuru emhepo, uye kugadzirisa kuchena kwesimbi yakanyungudutswa. Kuti unyatsoona iyo yakanyatso kufemera pasi kuvhuvhuta gasi kumanikidza maitiro paramita, yekumanikidza geji uye yekuyerera mita inogona kuisirwa pazasi inovhuvhuta gasi pombi, uye yepasi inovhuvhuta gasi kudzvanywa uye gasi rekupa vhoriyamu inogona kutariswa zvinoenderana neakasiyana ladle. parameters uye metallurgical zvinodiwa.

pakupedzisa

Kuti uvandudze mhedzisiro yekuvhuvhuta gasi pazasi pe ladle, kusarudza yakakwirira-yemhando yezvidhinha inofema ine yakakwirira yekupisa kuvhunduka kusagadzikana, permeability kuramba uye kukukurwa kwevhu ndiro danho rekutanga. Ukama huri pakati pekushandiswa kwesainzi uye zvidhinha zvemhando yepamusoro zvinofema zvinogona kutsanangurwa sekuwedzera
