KONTROL KUALITAS
1~ Pemeriksaan bahan baku yang masuk
2~ Pengelompokan bahan baku untuk menghindari campuran kelas baja
3~ Pemanasan dan Pencakar ujung untuk menggambar dingin
4~ Menggambar dingin dan penggulung dingin, pemeriksaan di jalur
5~ Pengolahan panas, +A, +SRA, +LC, +N, Q+T
6~ Perataan-Potong ke panjang yang ditentukan-Pengukuran selesai
7~ Pengujian mekanik di laboratorium sendiri dengan kekuatan tarik, kekuatan hasil, elongasi, kekerasan, dampak, struktur mikro dll
8~ Pengemasan dan Pengepakan.
100% dari tabung baja kami diperiksa dimensi
100% tabung baja kami diperiksa secara visual untuk memastikan mereka memiliki kondisi permukaan yang sempurna dan tidak ada cacat permukaan.
Uji arus pusaran 100% dan uji ultrasonik untuk menghilangkan cacat longitudinal dan transversal.
