軋輥生產商擇優推薦

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. .

冷軋輥在工作過程中要承受很大的軋制應力，加上軋件的焊縫、夾雜、邊裂等問題，容易導致瞬間高溫，使工作輥受到強烈熱沖擊，造成裂紋、粘輥、剝落甚至報廢。因此，冷軋輥要有抵抗因彎曲應力、扭轉應力、剪切應力引起的開裂和剝落的能力，同時也要有高的耐磨性。(2)semihardroll:thehardnessoftheShawisabout40to60。

Cold roll must bear a lot of rolling stress in the working process, add the weld, inclusion and edge crack of the rolled piece, which can easily lead to instantaneous high temperature, so that the work roll is subjected to strong heat shock, which causes crack, roll, peeling and even scrap. Therefore, the cold roller must resist the ability of cracking and spalling caused by bending stress, torsional stress and shearing stress, and also has high wear resistance.

什么是鑄造軋輥，鑄造軋輥主要有哪些種類？

鑄造軋輥是指將冶煉鋼水或熔煉鐵水直接澆注成型這一生產方式制造的軋輥種類。

鑄造軋輥按材質又可分為鑄鋼軋輥和鑄鐵軋輥兩類；按制造方法又可分為整體鑄造軋輥和復合鑄造軋輥兩類。

What are the casting rolls and what are the main types of casting rolls?

The casting roller refers to the type of rolls produced by direct casting of molten steel or molten iron.

The casting roll can be divided into two types: cast steel roll and cast iron roll according to material quality. According to the manufacturing method, it can also be divided into two types: integral casting roll and compound casting roll.
