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(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，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.

硬質(zhì)合金輥環(huán)廣泛應(yīng)用于高速線材軋機的精軋機架，以及部分高速線材軋機的預(yù)精軋機架和棒材軋機的精軋機架。硬質(zhì)合金軋輥的優(yōu)點是硬度高、耐磨性好，單槽軋鋼量可以達到高速鋼軋輥的兩倍。

The cemented carbide roller ring is widely applied to the finishing mill housing of high-speed wire rod mill, as well as the finishing mill for some high speed wire rod mill and the pre finishing mill and bar mill. The biggest advantage of the hard alloy roll is high hardness and good wear resistance, and the amount of single groove rolled steel can reach two times of the high speed steel roll.

既避免機械加工，又無補焊熱應(yīng)力熱影響，修正厚度也不受捆綁，一起產(chǎn)品所具有的耐磨性及金屬材料不具備的退讓性，確保修正部位的接觸協(xié)作。

Not only to avoid mechanical processing, but also to weld hot stress and heat, the correction thickness is not bound, and the wear resistance of a product and the non - concession of metal materials are not available, so as to ensure a hundred percent contact and cooperation of the corrected parts.
