 扁钢也称为带钢,可分为热轧扁钢和冷轧扁钢两种。热轧扁钢的横截面尺寸都较大,一般为成品钢材,多用于构件、桥梁、扶梯等,大一点尺寸的扁钢也可作为其他板带等钢材的坯料。热轧扁钢以直条交货。冷轧扁钢用扁钢冷轧机加工而成,原料为盘圆或是热轧扁钢,冷轧扁钢的尺寸一般都较小,宽度在40mm以下,厚度在20mm以下,冷轧扁钢相对于热轧扁钢,表面粗糙度更加良好,属于成品,直接可以拿来使用。多用于其他工艺的辅助加固(家具生产、石材生产),铁艺、建筑等行业也有大量的使用。
 
  介绍完扁钢,接下来说一下设备。扁钢冷轧机和扁钢热轧机,从名字上可以直接看出其用途,一个属于冷轧机一个属于热轧机,冷轧和热轧是两个完全不同的形态,扁钢冷轧机直接对盘圆进行轧机,工作的时候不需要对原料进行加热,几天扁钢冷轧机可以连成一条连轧生产线,在轧制的过程中为了防止轧辊的升温过快,一般会加装冷却装置,对轧辊进行降温处理,保证冷轧机轧辊的正常工作,也增加轧辊的使用寿命。热轧扁钢则是通过热轧机来完成,热轧扁钢一般用半连轧和连轧的形式,热轧的原料为废钢熔炼而成的钢坯,轧制出成品后经过冷床冷却,校直切断为定尺的直条。热轧扁钢因为其工艺,成品尺寸没有冷轧的那么精确,表面经过冷却后会有残留的氧化皮,粗糙度相对来说也比较差。
 
  我公司生产的扁钢冷轧机经过多年的实践与改进,已经相对成熟,不论从扁钢冷轧机的设备稳定性以及可操作性,在同行中都处于领先地位。如今,冷轧扁钢的使用逐渐广泛,有些行业对冷轧扁钢的要求也越来越高。这对我们做设备的来说,也产生了督促作用,顺应市场的需要,提高扁钢冷轧机自身的质量,不管是产量方面还是轧出成品外观尺寸方面,都要严格要求,投入更多的精力来提高设备自身的竞争力度,使扁钢冷轧机站稳市场的同时,走出国门,走向世界。
Flat steel, also known as strip steel, can be divided into hot rolled flat steel and cold rolled flat steel two. Hot rolled flat steel cross section size is large, generally for finished steel, more used for components, Bridges, escalators, etc. Hot rolled flat steel to be delivered in straight bars. Cold rolled flat steel with flat steel cold rolling machine processing, the raw material is round or hot rolled flat steel, cold rolled flat steel size is generally smaller, the width of 40mm, the thickness of 20mm, cold rolled flat steel relative to hot rolled flat steel, surface roughness is better, belongs to the finished product, can be used directly. It is widely used for the auxiliary reinforcement of other technologies (furniture production, stone production), iron art, construction and other industries.
 
 
 
After the introduction of flat steel, then said the equipment. Flat steel cold rolling mill and flat steel hot rolling mill, can directly see the purpose, from the name belongs to a cold rolling mill to a hot rolling mill, cold rolling and hot rolling are two totally different forms, flat steel cold rolling mill for wire rod rolling mill directly, work don't need to heating of raw material, a few days can be together as a flat steel cold rolling mill and rolling production line, in the process of rolling roll in order to prevent their rising too fast, usually the cooling device, the cooling roll, and guarantee the normal work of the cold rolling mill roll, also increase the service life of roll. Hot rolling flat steel is through the hot rolling mill to complete, hot rolling flat steel is generally used in the form of semi-continuous rolling and continuous rolling, hot rolling raw materials for scrap smelting billet, rolling finished products after cooling in a cold bed, straightening cut for the length of the straight bar. Hot rolled flat steel because of its process, the size of the finished product is not so accurate as cold rolled, after cooling surface will have residual oxide skin, roughness is relatively poor.
 
 
 
After years of practice and improvement, the flat cold rolling mill produced by our company has been relatively mature. No matter from the stability and maneuverability of the flat cold rolling mill, it is in the leading position in the industry. Nowadays, cold rolled flat steel is widely used, and some industries have higher and higher requirements for cold rolled flat steel. It, for we do equipment also had an urge effect, suit the needs of the market, improve their own quality, flat steel cold rolling mill both production and rolled out the product appearance size, should be strict requirements, put in more effort to improve the competitive strength of with the device itself, make flat steel cold rolling mill on the market at the same time, go abroad, towards the world.
