熱軋鋼捲俗稱黑皮鋼捲,可供再軋延、裁板、製管等,用途廣泛;熱軋鋼捲可在熱軋線,將扁鋼胚加熱至適當溫度後,經由粗軋、盤捲、精軋、層流冷卻,最後由盤捲機捲成熱軋粗鋼捲;並有吊運至調質線,經過必要的調質、裁剪、秤重、包裝、標記等作業而成調質鋼捲。
熱軋鋼捲強度足、韌性佳、焊接性良、加工成形易,除可做為冷軋產品的主要原料外,更可廣泛用於五金、汽車、家電零件加工、結構用管件、建築用管件、加工為建築結構用鋼等…
Hot rolled coils, a.k.a. black skin coils, can be suitable for re-rolling, slitting, and piping, and have a wide range of applications. Hot rolled products are made from slabs which are reheated in the hot strip mill at proper temperature, rolled in the roughing mill, through the coil box, rolled in the finishing mill, cooled in the laminar flow cooling system, and eventually down coiled into hot rolled bands in the down coil. The hot bands will be conveyed to the skin pass mill for pertinently tempering, crop shearing, weighing, packaging and marking to be further processed into tempered coils.
Hot rolled coils have the characteristics that include adequate strength, well toughness, good weldability, and easy formability, which can be used not only as the main materials in producing cold rolled coils, but also widely applied for hardware, automobile body plates, home appliances, structural pipes, construction pipes, and construction steels for structure.
