軋輥是軋機(jī)的重要部件,按照軋機(jī)類型可分為領(lǐng)帶軋機(jī)軋輥、型鋼輪機(jī)扎輥和鋼管軋機(jī)軋輥三大類。
板帶軋機(jī)軋輥的輥身呈圓柱形,熱乾板帶軋輥的輥身微凹,當(dāng)受熱膨脹時(shí),可保持較好的扳形。
Roll is an important part of the rolling mill. According to the type of rolling mill, it can be divided into three types: the tie mill roll, the type steel turbine ligation roll and the steel tube rolling mill roll.
The roll body of a strip rolling mill is cylindrical, and the roll body of the hot dry plate is slightly concave. When the heat is expanded, it can maintain a better shape.
冷軋板帶軋輥的輥身呈微凸,當(dāng)它受力彎曲時(shí)可保證良好扳形;型鋼軋機(jī)軋輥的輥身上有軋槽,根據(jù)型鋼軋制工藝要求,安排孔型。鋼管軋制中采用斜軋?jiān)碥堉频能堓佊袌A錐形、腰鼓形或盤形。
The roll body of the cold rolled strip roller is slightly convex. When it is bent by force, it can ensure good shape. There are grooves on the roller body of the section mill roll, and the pass is arranged according to the rolling requirements of section steel. The rollers of skew rolling rolling rolling principle of conical drum or disc.
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.
軋輥的品種和制造工藝隨冶金技術(shù)的進(jìn)步和軋鋼設(shè)備的演變而不斷發(fā)展。中世紀(jì)軋制軟的有色金屬時(shí)使用強(qiáng)度低的灰鑄鐵軋輥。18世紀(jì)中葉英國掌握了軋制鋼板用的冷硬鑄鐵軋輥的生產(chǎn)技術(shù)。
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.
