1. The size of the hot-rolled coil product is accurate, the thickness is uniform, and the thickness difference of the coil is generally not more than 0.01-0.03mm, which can meet the high-precision tolerance requirements.

2. Ultra-thin strips (up to 0.001mm or less) that cannot be produced by hot rolling can be obtained.

3. The surface quality of hot-rolled products is excellent, and there are no defects such as pitting and hot-pressed iron oxide that are common in hot-rolled coils, and coils with different surface roughness (smooth or pitted) can be produced according to user requirements. Rough surface, etc., to facilitate the processing of the next process.
