冷轧钢板由于有一定程度的加工硬化,韧性低,但能达到较好的屈强比,用来冷弯弹簧片等零件,同时由于屈服点较靠近抗拉强度,所以使用过程中对危险没有预见性,在载荷超过许用载荷时容易发生事故。

Due to work hardening of cold rolled steel plate, a certain degree of toughness is low, but can yield better than that used to cold spring piece parts, at the same time as the yield point is close to the tensile strength, so the use of risk is not predictable, prone to accidents in the load exceeds the allowable load.

1) 冷板采用冷扎加工表面无氧化皮,质量好。热轧钢板采用热扎加工表面有氧化皮,板厚有下差。

1) cold plate used in cold rolling surface nonscale, good quality. The hot surface oxide thickness of hot rolled steel, have difference.

2)热轧钢板韧性和表面平整性差,价格较低,而冷轧板的伸展性好,有韧性,但是价格较贵。

2 hot rolled steel plate toughness and surface roughness is poor, the price is low, while the cold rolled plate of good ductility, toughness, but the price is more expensive.

3)轧制分为冷轧和热轧钢板,以再结晶温度为区分点。

3) divided into cold and hot rolled steel plate, the recrystallization temperature is provided.

4) 冷轧:冷轧一般用于生产带材,其轧速较高。

4) cold rolling: cold rolling is generally used in the production of strip, the high speed.

热轧钢板:热轧的温度与锻造的温度

Hot rolled steel plate: hot rolling temperature and forging temperature

5)不电镀的热扎钢板表面成黑褐色,不电镀的冷扎板表面是灰色,电镀后可从表面的光滑程度来区分,冷扎板的光滑度高于热扎钢板。

5) hot plate surface plating black brown, plating cold rolled plate surface is gray, after plating from the surface smoothness to distinguish, lengzha board smoothness is higher than that of hot rolled steel plate.
