    Aluminum casting rolling mill in rolling form is divided into: continuous casting (such as two typical casting roller mill) and continuous casting and rolling (typical example hazret). According to the relative position of two rolls, the two roll casting mill in continuous casting and rolling mill can also be divided into three types: horizontal, inclined and vertical. The twin roll continuous casting mill designed by our company is mainly horizontal and inclined.

    The so-called continuous casting rolling of aluminum belt refers to the special processing equipment which combines the two processes of the casting and hot rolling of aluminum. During the rolling process, the casting roller will take away a lot of heat from the molten aluminum, so that the casting and crystallization process can be completed in a short time, and the pressure of the formed casting structure is also processed. Through the intermediate unit's pinch roll, hydraulic shear, eccentric guide roller and guide plate device, the casting and rolling plate is rolled into coil and finally transported by the unloading car to the coil storage rack.

    The main differences between the horizontal and the tilted double roll caster are:

    The connecting line of the center line of the two roll is different from the angle of the ground, the horizontal connection is perpendicular to the ground, the tilted connection and the ground are not vertical, and generally 15 degrees.

    When the roll changing operation is different, the tilting type casting and rolling mill needs to turn the paw to the vertical position of the ground before changing the roll, so that the roll changing operation can be carried out, while the horizontal casting mill can directly change the roll.

    The configuration is different, the inclined type needs the main drive removal mechanism, the archway rotation mechanism, and so on.

    Different from the horizontal, inclined to the remarkable characteristics of melt (i.e. liquid aluminum) by entering the two level and under the direction of upward, so that the injection of roll gap melt is strictly controlled in the static pressure is certain, by feeding mouth to rotate with uniform and continuous roll gap in melt supply. Compared with the horizontal casting rolling mill, the aluminum plate slab produced by this way has high compactness and low hydrogen content, and the slab has better quality than the horizontal one when producing double zero foil. So this is the main model of the current market.

    铝铸轧机按轧制形式分为:连续铸轧(典型如两辊式铸轧机)和连铸连轧(典型的比如哈兹莱特)。连续铸轧中的两辊式铸轧机按照两个轧辊的相对位置不同,又可分为水平式、倾斜式以及垂直式三种,而我公司设计双辊连续铸轧主要水平式和倾斜式为主。

    所谓铝带连续铸轧是指综合了铝的铸造和热轧两项工艺过程的专用加工设备。在轧制过程中,铸轧辊将铝液的大量热能迅速带走,使铝液在很短时间内完成铸造和结晶过程,同时对已形成的铸造组织进行压力加工。铸轧板经过中间机组的夹送辊、液压剪、偏导辊和导板装置到卷取机被卷成卷材,最后由卸卷车运到卷材储料架上。

    水平式与倾斜式双辊铸轧机的主要区别:

  • 两轧辊中心线的连线与地面的夹角不同,水平式的连线垂直于地面,倾斜式的连线和地面不垂直,且一般为15°
  • 换辊操作不同,倾斜式铸轧机在换辊时需要先将牌坊旋转到和地面垂直的位置才能进行换辊的操作;而水平式铸轧机可直接换辊。
  • 配置有差别,倾斜式的需要主传动移除机构、牌坊架旋转机构等。
  • 不同于水平式,倾斜式的显著特点为熔体(即液态铝)进入两个水平辊的方向为由下向上,这样可使注入辊缝的熔体被严格控制在一定的静压强下,由供料嘴均匀连续的向旋转着的辊缝中供给熔体。相较水平式铸轧机此种方式生产的铝板板坯组织致密性高,氢含量低,且此种板坯在生产双零箔时较水平式更为优质。因而这也是目前市场主推机型。
