Bagaimana untuk menerima relau lebur aruhan?

The acceptance of the relau lebur induksi is carried out in accordance with the technical specifications and standards. There are four steps: acceptance during the manufacturing process of the induction melting furnace, acceptance before leaving the factory, unpacking acceptance and final acceptance.

1. Acceptance during the manufacturing process of the induction melting furnace: Acceptance of the manufacturing process of each component and the materials, specifications, dimensions, etc. according to the technical specifications.

a. Penerimaan semasa proses pembuatan badan relau

The supplier shall submit the main material specifications of the furnace body and the furnace body manufacturing process to the purchaser for review before the furnace body is manufactured. During the manufacturing process of the furnace body, the supplier shall call the purchaser, and the purchaser shall assign technical personnel to supervise the manufacturing process.

b. Penerimaan semasa proses pembuatan gegelung aruhan

Pembekal hendaklah menyerahkan spesifikasi bahan (senarai bahan) dan proses pembuatan kepada pembeli untuk semakan sebelum gegelung aruhan dikilang. Semasa proses pembuatan, pembekal hendaklah memanggil pembeli, dan pembeli hendaklah menugaskan kakitangan teknikal untuk menyelia proses pembuatan.

c. Penerimaan semasa proses pembuatan kuk

Pengeluar kuk magnet akan mengikuti keseluruhan proses pengeluaran, termasuk: semakan senarai bahan; kajian semula bahan mentah, proses pengosongan, proses pembuatan, dan proses pemasangan.

d. Kabinet bekalan kuasa frekuensi pertengahan

Selepas kabinet bekalan kuasa frekuensi perantaraan dipasang, pembeli hendaklah menghantar juruteknik untuk memeriksa dan menerima komponen, reaktor, dan kabinet kapasitor pampasan dalam kabinet, dan mengambil bahagian dalam kerja penyahpepijatan bekalan kuasa.

f. Penerimaan semasa proses pemasangan keseluruhan

After the production of each component is completed, the purchaser shall be notified to supervise the assembly process when the entire induction melting furnace is assembled.

If there are disagreements between the two parties during the above-mentioned acceptance process, the supplier shall propose a solution, and the supplier can proceed to the next process after the buyer recognizes that the two parties have reached a consensus.

2. Factory acceptance of induction melting furnace

Pemeriksaan dan penerimaan sebelum meninggalkan kilang dijalankan oleh pengilang, dan pembekal hendaklah memberitahu kakitangan Pihak A untuk menjalankan pemeriksaan dan penerimaan awal mengikut “Spesifikasi Teknikal Relau Peleburan Aruhan” dan peruntukan berkaitan standard kebangsaan sebelum produk dihantar. Item pemeriksaan kilang adalah seperti berikut:

a. Penerimaan komposisi keseluruhan relau lebur aruhan;

Mengikut spesifikasi teknikal relau lebur aruhan, semak sama ada konfigurasi relau lebur aruhan memenuhi keperluan.

b. Electrical performance inspection

Measurement of the clearance between the induction coil and the furnace shell, the insulation resistance measurement of the induction coil to the furnace shell, the insulation withstand voltage test of the intermediate frequency coreless smelting furnace, and the insulation quality inspection of the capacitor to the ground.

c. Inspection of hydraulic system;

Audit by the product manufacturer.

d. Inspection of supporting parts, including inspections of models, specifications, factory qualified certificates, and related drawings;

e. Skop pembekalan, termasuk pemeriksaan kelengkapan dokumen teknikal kilang;

f. Penerimaan bahan dan saiz bas tembaga pemasangan.

J. Pemeriksaan pembungkusan.

3. Unpacking acceptance of induction melting furnace

The unpacking and acceptance work is carried out at the installation site. After all the products are delivered to the place of use, both parties shall check the quantity of the whole box according to the packing list, and check and accept the parts, accessories, and accessories of the products in each box. The name and quantity of the attached accessories and components, confirm whether the supplier is damaged or lost during transportation.

4. Final acceptance of induction melting furnace

Final acceptance is a comprehensive acceptance of product quality and performance. The time starts from the commissioning, and the relevant parameters will be assessed after the electric furnace runs normally for a week. The acceptance items are as follows:

a. Start-up acceptance of relau lebur induksi

Mulakan lima kali dalam keadaan relau kosong, dan kadar kejayaan ialah 100%; mulakan lima kali dalam keadaan cas relau penuh, dan kadar kejayaan ialah 100%;

b. IF power supply performance assessment

Masa keluaran kuasa malar, voltan DC, voltan frekuensi pertengahan, arus frekuensi pertengahan, frekuensi kerja, prestasi perkongsian arus penerus dwi, ​​hingar reaktor, dll. memenuhi spesifikasi teknikal relau lebur induksi.

c. Pengukuran suhu lebur

Suhu lebur keluli lebur memenuhi spesifikasi teknikal relau lebur aruhan

d. Pengukuran penggunaan kuasa dan kadar lebur litar utama relau

Kadar lebur diuji oleh piawaian kebangsaan, dan nilai purata tiga haba berturut-turut diambil, dan had atas tidak boleh melebihi 5%.

e. Pemeriksaan sistem laluan air

Periksa parameter teknikal menara penyejuk yang tertutup sepenuhnya, dan periksa litar air penyejuk tanpa resapan air. Bekerja secara berterusan untuk enam haba untuk menilai suhu air salur keluar menara penyejuk yang tertutup sepenuhnya.

f. Pengukuran kenaikan suhu badan relau dan setiap peranti dalam keadaan panas

Bekerja secara berterusan selama enam kali, penilaian kenaikan suhu setiap peranti memenuhi keperluan kenaikan suhu dalam spesifikasi teknikal relau lebur aruhan.

g. Hydraulic system

Apabila relau penuh, badan relau boleh berlepas dan jatuh dengan lancar, beroperasi secara fleksibel, dan semua persembahan memenuhi keperluan spesifikasi teknikal. Tiada kebocoran dalam litar minyak.

h. Sistem relau

The yoke and induction coil are installed in a reasonable layout, the waterway is unobstructed, and the water-cooled cable has no hard spots. The furnace frame has sufficient rigidity and runs smoothly when carrying the maximum loading.

i. Penerimaan semasa pemasangan

Pembersihan litar minyak, cat hijau pada paip air dan cat pendakap.

j. Project overall experience collection.

Penyeragaman pemasangan keseluruhan, pembekal produk sokongan, sama ada keperluan prestasi pengubah dipenuhi, dan sebagainya.

Selepas penerimaan muktamad diluluskan, kedua-dua pihak bersama-sama menandatangani laporan penerimaan ujian pentauliahan.
