(1)轧钢机械的高刚度保证了产品的高精度，容易实现负偏差轧制。

(2)能实现对称调整。这对于稳定操作，提高作业率，节省检修和更换导卫横梁时间，减少操作事故，避免轧件弯头、冲击、缠辊等工艺事故，提高导卫寿命具有重要意义。

(3)由于轧钢机械改变了力的传递途径、将压下螺丝的集中载荷改变为分散在轴承座两侧的分散载荷，使轴承和轴承座受力情况好，轴承寿命较普通轧机提高1．5倍以上，从而降低了产品的成本费用。

(4)该种轧钢机械的辊系在换辊前进行预安装并调整好，停车后10min左右即可换好新辊系。而调好的新辊系轧过一二根钢后即可保证产品合格。因此，本轧机预调性能好，换辊快，成材率高。  

(1) The high rigidity of steel rolling machinery ensures the high precision of the products and makes it easy to achieve negative deviation rolling.

(2) It can achieve symmetrical adjustment. This is of great significance for stabilizing operation, improving the operation rate, saving the time for maintenance and replacement of the guide beam, reducing operation accidents, avoiding process accidents such as bending, impact and entanglement of rolled pieces, and extending the service life of the guide beam.

(3) Due to the fact that the steel rolling machinery has changed the force transmission path, transforming the concentrated load of the pressing screw into a dispersed load distributed on both sides of the bearing housing, the force condition of the bearing and the bearing housing is better, and the bearing life is more than 1.5 times longer than that of ordinary rolling mills, thereby reducing the cost of the product.

(4) The roll system of this type of steel rolling machinery should be pre-installed and adjusted before changing the rolls. The new roll system can be replaced about 10 minutes after the machine stops. The newly adjusted roll system can ensure the product is qualified after rolling over one or two steel bars. Therefore, this rolling mill has good pre-adjustment performance, quick roll changing and high yield rate.
