The performance advantages of cold -rolled plates and hot -rolled plates

　　(1) The accuracy is higher, and the thickness difference between the cold rolling belt is not more than 0.01 ~ 0.03mm.

　　(2) The size is thinner, and the thinnest of cold rolling can be rolled 0.001mm.

　　(3) The surface quality is superior, and the cold -rolled steel plate can even produce the surface of the mirror surface; the surface of the hot -rolled plate is oxygen -oxide leather, anesthesia and other defects.

　　(4) Cold -rolled plates can adjust their school performance such as tensile strength and process performance such as stamping performance according to the user requirements.

　　Cold rolls and hot rolling are two different types of steel rolling technologies. As the name suggests, cold rolling is to make systems at room temperature. This kind of steel has a large hardness. Hot rolling is that steel is tied at high temperatures.

　　The hardness of the hot -rolled plate, easy processing, and good extension performance.

　　Cold -rolled plates have high hardness and are relatively difficult to process, but they are not easy to deform and have high strength.

　　The intensity of the hot rolled plate is relatively low, and the surface quality is almost (aerobic, low cleanliness), but the plasticity is good, generally the middle thick plate.
