軋輥產(chǎn)生彈性壓扁時(shí)可能軋制的板厚。在一定軋機(jī)上軋制一定的產(chǎn)品時(shí),隨著板帶的逐漸變薄,壓下越來越困難。當(dāng)板帶薄至某一限度后,不管如何旋緊壓下螺絲或加大液壓壓下的壓力,不管反復(fù)軋制多少道,由于軋輥產(chǎn)生彈性壓扁而不可能再使產(chǎn)品變薄。Rollisanimportantpartoftherollingmill。這一極限厚度稱為可軋厚度。

The smallest plate thickness may be rolled when the roll produces elastic squash. When a certain product is rolled on a certain rolling mill, with the gradual thinning of the strip, it is becoming more and more difficult to press down. When the strip is thin to a certain limit, no matter how to tighten down the screw or increase the pressure of hydraulic pressure, no matter how many rolls are repeatedly rolled, it is  for the product to become thin due to the elastic flattening of the roll. This limit thickness is called the minimum rolling thickness.






實(shí)踐表明,帶雙鍍槽的軸頭在使用過程中,鑲槽壁容易崩裂,目前常用易加工的帶平臺(tái)的袖頭代替雙因槽的抽頭。

直徑超過400mm的冷軋軋輥,在鍛造后,多半在中心饅一個(gè)670一250mm的通7L。這樣,一力面可以使軋輥經(jīng)熱處理店的內(nèi)應(yīng)力分朽均勾;另一方面在軋輥表面淬火時(shí),可對軋輥通水冷卻,提高淬火效果。


Practice shows that, with double bath head is in use, insert groove wall is easy to crack, at present common processing platform with the cuff instead of double slot for tap.

Cold roll diameter of more than 400mm, after forging, mostly in the 7L center. A 670 250mm. So, on one hand can make the roller stress heat treatment shop allocation hook are; on the other hand, the roll surface quenching, the water cooling roller, improve the quenching effect.




由于軋制過程是連續(xù)的過程,因此操作人員需要不斷檢測軋輥狀況,使生產(chǎn)出來的產(chǎn)品滿足用戶對更嚴(yán)格的公差和表面質(zhì)量的要求。



As the rolling process is a continuous process, the operator needs to continuously detect the roll status to meet the more stringent tolerance and surface quality requirements of the products produced.
