              楔橫軋機類型有輥式、板式和單輥弧式楔橫軋機。三種類型的楔橫軋機相比,板式楔橫軋機模具制造較為簡單,模具的調整比較容易,因而軋件的精度較高,并且工藝可靠.



              The cross wedge rolling mill has roller type, plate type and single roll arc cross wedge rolling mill. Compared with the three types of cross wedge rolling mill, the mould manufacturing of the plate type cross wedge rolling mill is simpler and the adjustment of the die is easy, so the precision of the workpiece is high and the process is reliable.


              軋制時毛坯的位置固定,因此不需設置側向支撐毛坯的導向尺。總之,它適用于軋制復雜外形結構,精度要求高,零件品種變換很多的情況。但其行程大小受到限制,所以,變形程度也受到影響,同時,板式軋機有空行程,故影響到生產率和變形程度都不能很大。



              The of the blank is fixed during rolling, so there is no need to set the guide bar of the side supporting blank. In short, it is suitable for rolling complex shape structure with high accuracy and many varieties of parts. But the stroke size is limited, so the degree of deformation is also affected. At the same time, the plate mill has an empty travel, so the productivity and deformation can not be very large.


              使用熱軋的第二個優點就在于其可以適當的改善金屬以及合金材料的加工工藝性能。也就是說,其可以把較大的晶粒進行破碎,同時可以減少裂紋的出現,這樣一來,也就相當于減少了鑄造過程中的缺陷問題,提高合金的加工性能。



              The second advantage of hot rolling is that it can appropriately improve the processing performance of metal and alloy materials. That is to say, it can break the larger grain and reduce the appearance of the crack, which is equivalent to reducing the defects in the casting process and improving the processing performance of the alloy.


              還有三輥軋機,軋機專業廠家介紹,這種軋機由于本身的優勢并不突出,所以使用的比較少。那么,四輥軋機具有怎樣的特點恩?這種類型的軋機的工作輥直徑較小,傳遞軋制力矩,軋延壓力由直徑較大的支承輥承受。其的優點在于相對剛度高、壓下量大、軋延力小,比較適合軋制較薄的板材。所有的軋件均被送到冷床上的固定位置,由移鋼機構將軋件從步進梁上翻出并移至冷床的輸出輥道上。




              There are three-high mill, mill professional manufacturers , this kind of mill because of its advantages are not prominent, so the use of less. So, what are the characteristics of the four high rolling mill?也就是說,其可以把較大的晶粒進行破碎,同時可以減少裂紋的出現,這樣一來,也就相當于減少了鑄造過程中的缺陷問題,提高合金的加工性能。 The working roll diameter of this type of mill is smaller, the rolling torque is transmitted, and the rolling pressure is borne by the backup roll with larger diameter. Its advantages are high relative stiffness, large reduction and small rolling force, so it is suitable for rolling thin sheets.
