520轧机哪家好-圣霖国际(在线咨询)-520轧机

闭口式机架为一整体铸件制成。这种机架形式在型钢车间中小型轧机上应用较多。其优点是强度和刚度较高，辊跳值较小，产品精度较高。其主要缺点是制造比较困难，520轧机哪家好，装卸、换辊不方便。轧制压力较大、对轧件尺寸要求比较严格时常采用闭口式机架。如初轧机、型钢连轧机和型钢成品轧机等。

The closed framde of a whole castings. This type of frame is used more in the *all and medium mill in the steel workshop. Its advantages are that the strength and stiffness are high， the roll jump value is *all and the precision of the product is high. It*ain disadvantage is that it is difficult to manufacture， and it is inconvenient to load and load and change the roll. When the rolling pressure is larger and the requirements for the size of the rolled piece are strict， the closed frame is often used. Such as the early rolling mill， the type steel continuous rolling mill and the steel finished rolling mill， etc.

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， lo*g and unlo*g，520轧机， 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.

H型钢在冷床上直立冷却后，由辊道送至变节距辊式矫直机进行长尺矫直，520型号轧机，经成排台架成排后，由冷锯机切成6～24m定尺。切成定尺的轧件经人工目测检查后，进入堆垛台架堆垛，520轧机生产商，经打捆、称重、标牌后进入成品台架，由成品跨吊车吊运入库、发货。

H type steel upright in the cooling bed after cooling by roller to pitch roller straightening machine straightening ruler， the rows of bench rows， a cold sawing machine i* 6 ~ 24m length. The rolled pieces， which are cut i* fixed lengths， are inspected and inspected after manual inspection. They enter stacks stacking， and then enter the finished rack by bundling， weighing and sign.
