實踐表明，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670一250mm的通7L。這樣，一力面可以使軋輥經熱處理店的內應力分朽均勾；另一方面在軋輥表面淬火時，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.

軋機上使金屬產生連續塑性變形的主要工作部件和工具。軋輥主要由輥身、輥頸和軸頭3部分組成。

輥身是實際參與軋制金屬的軋輥中間部分。它具有光滑的圓柱形或帶軋槽的表面。輥頸安裝在軸承中，并通過軸承座和壓下裝置把軋制力傳給機架。

The roller body is the middle part of the roll that actually takes part in rolling the metal. It has a smooth cylinder or a surface with a groove. The roller neck is installed in the bearing and passes the rolling force to the rack through the bearing seat and the press down device. .

軋輥的品種和制造工藝隨冶金技術的進步和軋鋼設備的演變而不斷發展。中世紀軋制軟的有色金屬時使用強度低的灰鑄鐵軋輥。18世紀中葉英國掌握了軋制鋼板用的冷硬鑄鐵軋輥的生產技術。

The variety and manufacturing process of roll have been developed with the progress of metallurgical technology and the evolution of steel rolling equipment. The use of low strength gray iron rolls in the Middle Ages when rolling soft nonferrous metals. In the middle of the eighteenth Century, Britain mastered the production technology of cold cast iron rolls used for rolling steel plates.

這些應力沿輥身的散布是不均勻的、不斷改變的，其原因不只有規劃要素，還有軋輥在運用中磨損、溫度和輥形的不斷改變。

The dispersion of these stresses along the roll is uneven and ctantly changing, and the reas are not only the planning elements, but also the ctant change of wear, temperature and roll shape in the use of the rolls.
