圣霖国际-大连rolling mill

开坯机为两辊水平轧机，坯料送至轧机前后，320rolling mill，根据轧制程序表进入相应的轧槽可逆轧制，并通过翻钢装置将轧件夹紧进行翻转。一般轧制5-7道次(***多9道次)。

The blooming machine is a two roll horizontal mill， and the billet is sent to the front and rear mills. According to the rolling schedule， the roll is rolled into the corresponding rolling groove，450rolling mill， and the workpiece is clamped and turned through the turning device. The general rolling is 5-7 times (up to 9 times).

轧制技术的有关问题:

般在板边缘较薄，400rolling mill，扎或纵厚度偏差就叫做板凸度。如果板凸度足够大，板厚偏差可以达到一定值，以至于钢板不适用于在严格要求板厚精度的场合。当厚度偏差增大（在板宽方向上厚度不同）导致在材料设计后产品损失中应考虑增加板厚边缘。

It is thinner on the edge of the plate， and the deviation of the ligation or longitudinal thickness is called the plate convexity. If the plate convexity is large enough，大连rolling mill， the thickness deviation of the plate can be reached to a certain value so that the steel plate is not suitable for the situation where the thickness of the plate is strictly required. When the thickness deviation increases (the thickness is different in the width of the plate)， the thickness edge of the plate should be added to the loss of the product after the material is designed.

开口式机架由机架底座和上横梁组成。

开口式机架是型钢车间***常见的一种机架形式。这种机架的优点是制造简单，装卸、换辊方便。其缺点是强度和刚度较低，轧辊辊跳值较大，影响产品精度，故只适用于大型轧机。

The open frame is of the frame base and the upper cross beam.

The open frame is one of the most common forms in the steel workshop. The advantages of this frame are simple manufacturing， loading and unloading， and convenient for roll change. Its disadvantage is that its strength and stiffness are low， the roll roll value is larger and the precision of the product is affected， so it is only suitable for large rolling mill.
