Itu berikut adalah an ikhtisar dari dua baja pipa proses proses% 3a
Itu dingin -tarik baja pipa kegunaan panas -digulung baja gulungan as mentah bahan% 2c dan dingin bergulir bergulir berguling digulung keras digulung bergulir. Plastik indikator are berkurang% 2c so stamping kinerja kemauan memburuk dan bisa hanya menjadi digunakan untuk sederhana deformasi bagian. Rolling hard rolling can be used as a raw material for thermal galvanized factory, because the thermal galvanized units are equipped with annealing line. Rolling rolling rolling weight is generally 6 ~ 13.5 tons, and the inner diameter of the steel roll is 610mm.
Umumnya% 2c dingin bergulir piring dan gulungan harus menjadi terus menerus anil (CAPL unit) atau an anil dari penutup -jenis tungku untuk menghilangkan dingin pengerasan dan bergulir stres untuk mencapai mekanik kinerja indikator ditentukan dalam yang sesuai standar.
The surface quality, appearance, and size accuracy of cold -rolled steel plates are better than hot -rolled plates, and the thickness of its product is thinner to about 0.18mm. Deep processing of the product with cold rolling steel rolls as a substrate has become a high value -added product. Such as electroplating, hot -dip galvanized, fingerprint -resistant electroplating, color coating steel plate rolls and vibration -reducing composite steel plates, PVC compound film steel plates, etc., these products have excellent quality such as beautiful, high anti -corrosion, etc., and have been widely used. Cold -rolled steel rolls must be refined after annealing, including cutting head, tail, cut edge, flat, flat, heavy roll, or longitudinal cutting plate. Cold -rolled products are widely used in automotive manufacturing, home appliance products, instrument switches, construction, office furniture and other industries. The weight of each package after the steel plate is 3 ~ 5 tons. Flying scores are generally 3 ~ 10 tons/volume. The inner diameter of the steel roll is 610mm.
