Peraturan Operasi Pembuatan Relau Frekuensi Menengah

1. Preparation sadurunge produksi.

1. When taking over, check first. Understand the use of furnace lining, whether the production tools are complete, and whether the furnace panel is exposed.

2. For every two furnace bases as a group, prepare ferrosilicon, medium manganese, synthetic slag, and heat preservation agent in place, and place them in the middle of the furnace.

3. Scrap steel must be prepared and the furnace must not be opened if there is a shortage of materials.

4. Seprei karet isolasi ing kompor kudu dilebokake, lan ora ana celah sing ditinggalake.

2. Produksi normal

1. Lapisan tungku anyar bakal dipanggang kanthi ketat sesuai karo persyaratan proses panggangan tungku anyar, lan wektu panggangan kudu luwih saka 2 jam.

2. First add a small suction cup to the furnace to protect the furnace lining. It is not allowed to directly add bulk materials into the empty furnace, and then the furnace front worker should add the small materials scattered around the furnace into the furnace in time, and it is strictly forbidden to drop them. Under the stove, silicon steel sheets and punches are only allowed to be used in the oven, and they are not allowed to be used in the rest of the time.

3. The disk hoist lifts the material onto the stove from the stockyard, and the foreman sorts the scrap steel. The sorted inflammable and explosive materials are directly placed in the special receiving box and registered and confirmed by the stove security.

4. The flammable and explosive special inbox is placed between the two sets of furnace bases, and no one can move it at will.

5. Panganan ing ngarepe tungku umume dipakani kanthi manual. Sawise kompor diurut kanthi tliti, dawane bahan kurang saka 400mm, lan bahan sing dipilih kanthi ati-ati dening manajer tungku bisa ditambah nganggo cangkir sedhot. Komandan nyopir minangka saben kursi tungku sing cilik. Manajer tungku, yen wong liya mrentah cangkir nyedhot nyopir, operator nyopir ora diidini.

6. Jumlah panganan sing nyedhot cangkir nyedhot kudu dikontrol. Sawise ditambahake, baja bekas ora diidini ngluwihi permukaan tungku tungku tungku frekuensi menengah. Kethokan sing kasebar ing sekitar cangkeme tungku kudu diresiki nganggo cangkir sedhot. Sajrone proses panganan, area sekitar tungku frekuensi menengah kudu dijaga resik kanggo nyegah Mudhunake baja besi nyebabake koil induksi utawa sambungan kabel bisa murup.

7. It is strictly forbidden to pile a large amount of scrap steel on the stage, and the total amount is controlled within 3 suction cups to reduce the difficulty of scrap sorting.

8. In the event of an explosion, the operator should immediately turn his back to the furnace mouth and leave the scene quickly.

9. Sajrone proses pra-panganan, kanggo bahan sing dawa, blok gedhe kudu ditambah mujur menyang tungku kanggo nyawiji ing kolam cair sawayah-wayah. Dilarang banget gabung ing kothak kanggo nyebabake kreteg. Yen bahan tungku ditemokake kreteg, jembatan kasebut kudu dirusak sajrone 3 menit, supaya bahan tungku bisa cepet nyawiji ing kolam cair. Yen jembatan kasebut ora bisa dirusak ing 3 menit, jembatan kasebut kudu dirusak amarga gagal listrik utawa ngreksa panas sadurunge tenaga disuplai kanthi normal.

10. For some scrap steel that is overweight and needs more than 2 people to move into the furnace, it is strictly forbidden to throw it into the furnace, and an excess should be made on the furnace edge, and then carefully pushed into the furnace.

11. Nalika kethokan tabung ditambahake ing tungku, sisih ndhuwur pipa kudu ing arah nutul baja, ora ing arah operasi manungsa.

12. Kanggo lempengan casting baja terus adhem lan cendhak cendhak ing sendhok slag lan tundhuk, baja cair ing tungku frekuensi menengah kudu dipasang ing tungku sawise tekan 2/3 utawa luwih, lan ora kena disabetake lapisan tungku.

13. Nalika baja cair ing tungku frekuensi menengah tekan luwih saka 70%, njupuk conto kanggo dianalisis. Sampel ora duwe cacat kayata bolongan nyusut, lan batang baja ora bakal dilebokake ing bilet sampel. Sawise asil komposisi kimia saka sampel dipikolehi, personel sing nyiapake elemen kasebut bakal nemtokake miturut kahanan komprehensif rong tungku kasebut. Jumlah paduan sing ditambahake.

14. Yen analisis kimia ing ngarepe tungku nuduhake manawa karbon iku dhuwur, tambahkan sawetara bahan kimia oksida besi kanggo dekarburisasi; yen nuduhake manawa karbon kurang, tambahi sawetara zat besi besi untuk recarburisasi; yen aliran rata-rata tungku loro kurang saka utawa padha karo 0.055%, nggeser kabeh nalika nutul. Slag, tambahake jumlah slag sintetis sing ditambahake kanggo desulfurisasi. Ing wektu iki, suhu nutul kudu ditambah kanthi tepat. Yen aliran rata-rata tungku loro yaiku ≥0.055%, baja cair kudu diobati ing tungku sing kapisah, yaiku baja cair kanthi isi belerang sing dhuwur kudu dibuwang menyang sendhok. Sijine menyang tungku liyane, banjur tambah sawetara pukulan lembaran baja silikon menyang rong tungku kanggo peleburan, banjur tutul baja. Yen fosfor dhuwur, mung bisa diproses ing tungku sing kapisah.

15. Sawise kabeh baja sisa ing tungku wis dilebur, klompok ing ngarepe tungku bakal nindakake pembuangan slag sing goyang. Sawise mbuwang slag, pancen dilarang nambah kethokan udan, berminyak, dicet lan tabung menyang tungku. Bahan garing lan resik kudu digunakake ing proses peleburan. Siyap-siyap Sawise waja cair ing tungku kebak, ngresiki slag ing siji wektu. Sawise diresiki, tambahi campuran kanthi cepet kanggo nyetel komposisi. Baja bisa disentuh luwih saka 3 menit sawise paduan ditambah. Tujuane yaiku supaya campuran paduan duwe komposisi seragam ing tungku.

16. Suhu nutul: Casting terus ing ndhuwur 1650—1690; wesi cair udakara 1450.

17. Ukur suhu baja cair ing ngarepe tungku, lan kontrol kurva transmisi daya miturut suhu nutul lan wektu nutul sing dibutuhake kanthi casting terus. Dilarang banget supaya tungku frekuensi menengah ing tahap suhu dhuwur (suhu nahan dikendhaleni ing ngisor 1600 ° C).

18. Sawise nampa kabar babagan nutul baja casting terus, suhu mundhak kanthi cepet. Tingkat kenaikan suhu tungku frekuensi penengah ing tungku cair tungku lengkap: udakara 20 ℃ / menit sadurunge 20 tungku; udakara 30 ℃ / menit kanggo tungku 20-40; lan luwih saka 40 tungku udakara 40 ° C / menit. Ing wektu sing padha, cathet manawa suhu sing luwih dhuwur ing tungku, laju panase luwih cepet.

19. Nalika tungku pertama disentuh, 100 kg slag sintetis ditambahake ing sendok kanggo ngreksa panas, lan sawise tungku nomer loro ditabuh, 50 kg agen panutup ditambahake ing ladle kanggo ngreksa panas.

20. Sawise tungku frekuensi menengah rampung, priksa lapisan tungku kasebut kanthi tliti, lan pareng banget diwutahake banyu menyang tungku supaya adhem; yen sawetara bagean saka tungku tungku korosi parah, tungku kasebut kudu didandani kanthi tliti sadurunge tungku diuripake. Kelembapan ing tungku kudu nunggu Panganan mung bisa rampung sawise nguap garing. Sepisanan nambah cangkir sedhot baja silikon ing tungku, lan banjur tambah baja kethokan liyane. Tungku pertama sawise ndandani tungku kudu ngontrol kurva pasokan listrik, saengga lapisan tungku duwe proses sinter kanggo njamin perbaikan tungku. Akibate, dilarang banget nambah sampah ing tungku sanalika sawise ndandani tungku.

21. During the whole production process, it is strictly forbidden to expose the furnace surface to the outside, and the insulating rubber should be replaced in time if it is damaged.
