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.
(1)軟輥;肖氏硬度約為30一40,用于開坯機(jī)、大型型鋼軋機(jī)的租軋機(jī)等。
(2)半硬輥:肖氏硬度約為40一60,用于大型、中型、小型型鋼軋機(jī)和鋼板輪機(jī)的租軋機(jī)。
(3)硬面輥:肖氏硬度約為60一85,用于薄板、中板、中型型鋼和小型型鋼軋機(jī)的稿軋機(jī)及四輥軋機(jī)的支撐輥。
(4)特硬輥le氏硬度約為85—100,用于冷軋機(jī)。
(1) soft roll; the hardness of Shaw is about 30 40. It is used for the renting rolling mill of the billet machine and the large steel mill.
(2) semi hard roll: the hardness of the Shaw is about 40 to 60. It is used for the renting rolling mill of large, medium, small type steel mill and steel plate turbine.
(3) hard roll: Shore hardness of about 60 to 85, for supporting roller mill release sheet, plate, medium and small steel mill and four roller mill.
(4) the hardness of the hard roll Le is about 85 - 100 for cold rolling mill.
軋機(jī)上使金屬產(chǎn)生連續(xù)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(shí)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(jī)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. .
按軋輥材質(zhì)分有鋼軋輥、鑄鐵軋輥、硬質(zhì)合金軋輥、陶瓷軋輥等;按制造方法分有鑄造軋輥、鍛造軋輥、堆焊軋輥、鑲套軋輥等;按所軋鋼材狀態(tài)分有熱軋輥、冷軋輥。各種分類可以相應(yīng)組合而使軋輥有更明確的含義,如熱軋帶鋼用離心鑄造高鉻鑄鐵工作輥。
According to the roller material, there are steel rolls, cast iron rolls, hard alloy rolls, ceramic rollers, etc. according to the manufacturing method, there are casting rolls, forging rolls, hardfacing rolls, inlaid rolls and so on. According to the rolled steel status, there are hot rollers and cold rollers. Various classificati can be combined to make the roll more explicit, such as the casting of high chromium cast iron working roll for hot rolled strip.
