Pfupiso yeChigadzirwa - Dambudziko reEAF Slag Pot

An Hari yeEAF ine slag(kanachirongo chemagetsi chesimbi chesimbi) haisi diki chete seBOF converter pot. Inoshanda pasi pemhando dzakasiyana zvachose dzezvinonetsa zvinoita kuti ive imwe yemhando dzinonyanya kuomesesa mugayo resimbi.

Zvitofu zvemagetsi zvinogadzira tsvina muzvikamu zvakasiyana-siyanaMaminetsi 45–90– kazhinji kupisa 12 kusvika 20 pazuva. Kutenderera kwega kwega kunosanganisira:

1. Kuzadzaine tsvina yakanyungudutswa pa1,600–1,700°C (kusanganisira madonhwe esimbi)

2. Kubataukuwo hari ichifambiswa nepasi risina kuenzana

3. Kurasa mararakuburikidza nekutsveyama kwekrini, dzimwe nguva nekurovera pamucheto wegomba reslag

4. Kutonhodza kwemhepokusvika pasi pe300°C usati wazadza rimwe zuva - zvichiita kuti pave nekunyanyisakuvhunduka kwekupisa

5. Kusiyana nehari dzeBAF dzinoshandiswa sema "slag" dzinowanzo gamuchira "slag" imwe chete pakuchinjana, hari dzeEAF dzinogona kubatwa ne "slag"kupisa nekutonhora nekukurumidza kusvika ka20 pazuvaKutenderera uku kwekupisa kwakanyanya kunotungamira kukuneta kwekupisa- nzira yekukundikana #1 yemapoto eEAF slag.

Pamusoro pezvo, kemikari yeEAF slag inosiyana zvakanyanya zvichienderana nemhando yetsvina, kuwedzerwa kwe alloy, uye maitiro ekunatsa. Slag inogona kuva ** yakapfava** (yakakwira CaO2, inonamira) kanaane asidhi(SiO₂ yakakwira, mvura). Chimwe nechimwe chinoda chimiro chemukati chakasiyana uye mhinduro yezvinhu.

Sei Uchifanira Kusarudza Simbi Yesimbi Yekushongedza Hari Yako yeEAF?

Chinhu Kubatsira Kwakanangana neEAF
Simbi yeNb-V Microalloy Huwandu hushoma hwemiganho ye niobium ne vanadium pin, zvichinonotsa kutanga kwekuputika kwemhepo ine simba. Zvakaratidzwa kuti zvinowedzera kukundikana kwemitambo ne70% zvichienzaniswa nesimbi yakaumbwa.
Kudzima Kwakakurumidzirwa + Kwakanyoroveswa Mushure mekuomesa, mhepo inomanikidzwa (kwete mhepo isina kugadzikana) inogadzira chimiro chepearlite + bainite chakanakisa - ichidzivirira zvakanyanya kupisa.

Mibvunzo Inowanzo bvunzwa (Mibvunzo Inowanzo bvunzwa) - EAF Specific

Mubvunzo: Ndingaziva sei kana EAF yangu ichida poto yeslag chaiyo?
A: Kana uchipisa zvinopfuura gumi pazuva kana kuti ukaona maburi mukati memwedzi gumi nemiviri pamapoto akajairwa, unoda dhizaini yakagadziriswa neEAF. Zvakare, kana ukaona tsvina ichinamira zvakanyanya kana kuti ichida kupwanyika nemaoko, chimiro chedu chekudzivirira kunamira chichabatsira.

Mubvunzo: Ndingashandisa poto imwe chete yeslag here paBOF neEAF?
A: Hazvikurudzirwi - Mapoto eEAF akagadzirwa kuti akwanise kutenderera nekukurumidza, madziro akatetepa, uye ane hunhu hwakasiyana hwekunamatira tsvina. Kushandisa mapoto eBOF muEAF kunotungamira pakutsemuka nekukurumidza; kushandisa mapoto eEAF muBOF kunogona kudzipisa zvakanyanya. Shandisa mapoto akatsaurirwa nguva dzose.

Mubvunzo: Munopa zvirongwa zvekubhadhara mari here kana kuti zvekuchinjana mari muhari?
A: Ehe - tine poto yesimbi inoshandiswa pakugadzira: unobhadhara patani yesimbi inogadzirwa, uye isu tine poto dzacho uye tinodzigadzirisa. Chipo chemakore mashanu. Bvunza ruzivo rwakadzama.

Q: Ndeipi nguva yehupenyu hwekudzivirira kunamatira?
A: Pasi pemabasa enguva dzose eEAF (slag yekutanga, 15 cycles/day), kuputira kunotora mwedzi 9-12. Kuputira patsva kunogona kuitwa mufekitori yenyu nevashandi vedu (kana isu tinokupai kit yekuputira). Mari yekutsiva machira i~15% yemutengo wehari itsva.

Mubvunzo: Unoita sei kana poto ikangoerekana yaparara?
A: Tinochengeta midziyo midiki yekutakura zvinhu (mapoto maviri kusvika mana) yehukuru hwakaenzana hweEAF mudura redu. Kune vatengi vane chibvumirano chebasa, tinotakura zvinhu nendege mukati memaawa makumi manomwe nemaviri.

Mubvunzo: Unogona here kuwedzera ma sensor ekupisa muhari?
A: Ehe - tinogona kuisa thermocouple pockets (kusvika panzvimbo ina) neInconel sheathing. Masensa anogona kubatanidzwa nemonitor inotakurika kana kubatanidzwa neplant DCS yako.

Mubvunzo: Chii chinodiwa pakunamira slag yeEAF?
A: Ndiro yemukati inofanira kugadzirwa nemuchina weRa ≤ 6.3 μm. Nzvimbo dzakagadzirwa nesimbi dzinoita kuti irambe yakanamatira. Dhizaini yedu ine mativi maviri pamwe chete nekugadzira zvinhu zvakanaka inoderedza kunamira zvakanyanya.

Mubvunzo: Ndingachenesa sei poto yeslag kana slag ikaita chando mukati?
A: Usamboshandisa michina yekurovera zvakananga pamadziro ehari - izvo zvinokonzera kutsemuka. Pane kudaro, shandisa oxygen lancing kucheka mugero, wobva wapisa hari zvakaenzana. Kuvhara kwedu kunodzivirira kunamira kunoderedza zviitiko zvekuomesa chando.
