冷轧钢板分为三代:沸腾钢是第一代,铝镇静钢是第二代,无间隙原子钢是第三代。冷轧:以热轧钢卷为原料,经酸洗除垢后进行冷连轧,成品为轧制硬卷。连续冷变形引起的冷加工硬化增加了轧制硬线圈的强度和硬度,降低了韧性和塑性指数,因此冲压性能会变差,只能用于简单变形的零件。由于热镀锌机组都配有退火生产线,因此硬卷可用作热镀锌厂的原材料。轧制的硬卷重量一般为6~13.5吨,钢卷在热轧酸洗卷上常温连续轧制。内径为610毫米。

Cold-rolled steel plate is divided into three generations: boiling steel is the first generation, aluminum calm steel is the second generation, and gapless atomic steel is the third generation.Cold rolling: with hot-rolled steel roll as raw material, cold and continuous rolling after acid washing and scale, the finished product is rolled hard roll.Cold processing hardening caused by continuous cold deformation increases the strength and hardness of the rolled hard coil, and reduces the toughness and plasticity index, so the stamping performance will deteriorate and can only be used for simply deformed parts.Since thermal galvanizing units are equipped with annealing lines, hard rolls can be used as raw material for thermal galvanizing plants.The rolled hard roll weight is generally 6 to 13.5 tons, and the steel roll is continuously rolled at room temperature on hot-rolled acid washes.The inner diameter is 610 mm.

冷轧钢就是经过冷轧生产的钢。冷轧是在室温条件下将钢板进一步轧薄至为目标厚度的钢板。和热轧钢板比较,冷扎钢板厚度更加精确,而且表面光滑、漂亮,同时还具有各种优越的机械性能,特别是加工性能方面。因为冷轧原卷比较脆硬,不太适合加工,所以通常情况下冷轧钢板要求经过退火、酸洗及表面平整之后才交给客户。冷轧最大厚度是0.1--8.0MM以下,如大部份工厂冷轧钢板厚度是4.5MM以下;最少厚度、宽度是根据各工厂的设备能力和市场需求而决定。

Cold-rolled steel is the steel produced after cold-rolled steel.Cold rolling is a sheet further rolled to the target thickness at room temperature.Compared with the hot-rolled steel plate, the thickness of the cold-tie steel plate is more accurate, and the surface is smooth and beautiful, but also has a variety of superior mechanical properties, especially the processing performance.Because the cold rolled original coil is relatively brittle and not suitable for processing, the cold rolled steel plate should usually be handed over to the customer after annealing, pickling and surface leveling.The maximum thickness of cold-rolling is below 0.1--8.0MM, if most factory cold-rolled steel plate thickness is less than 4.5MM; the minimum thickness and width are determined based on the equipment capacity and market demand of each plant.

冲压五金冷轧板

一般冷轧钢如镀锌、彩钢板都须退火,所以塑性和延伸率也较好,广泛应用于汽车、家电、五金等行业。冷轧板表面有一定的光洁度,手摸起来比较光滑,主要是酸洗之功。热轧板一般表面光洁度达不到要求,所以热轧钢带需冷轧,还有热轧钢带厚度最薄一般在1.0mm,冷轧可达到0.1mm。热轧是结晶温度点以上的轧制冷轧是结晶温度点以下的轧制。

Generally, cold-rolled steel such as galvanized, color steel plate must be annealed, so the plasticity and elongation rate are also good, widely used in automobile, home appliances, hardware and other industries.Cold-rolled plate surface has a certain degree of cleanliness, the hand touch is relatively smooth, mainly is the work of pickling.The general surface smoothness of the hot rolled plate does not meet the requirements, so the hot rolled steel strip needs cold rolling, and the thinnest thickness of the hot rolled steel strip is generally 1.0mm, and the cold rolling can reach 0.1mm.Hot rolling is rolling above the crystallization temperature point, and cold rolling is rolling below the crystallization temperature point.
