螺纹钢筋是一种具有横向三头螺纹凸起和两条纵肋的钢筋(图1)。热轧此种钢材必须采用特殊的轧辊,特别是在成品道次,轧件各个部分,是在不同条件下变形的:在轧辊辊身上,轧出横向凸起部分的切入,比成品的内径为深,侧面的纵肋是变形金属在孔型的辊缝里轧成的,孔型的这个地方是由冷硬铸铁制成的。轧制螺纹钢筋,对轧辊有以下几个基本的要求:1.要有高的强度,因为轧辊所受的压力,比轧
The rebar is a rebar with a transverse three-pronged projection and two longitudinal ribs (Figure 1). Hot rolled steel must be used special rolls, especially in the finished pass, rolling all parts of the deformation is under different conditions: roll roll body, rolling out of the lateral raised part of the finished product than the inner diameter of Deep, the side of the longitudinal rib is deformed metal rolling in the pass into the pass, the hole type of this place is made of chilled cast iron. Rolling of steel, the roll has the following basic requirements: 1. To have high strength, because of the pressure roller, than the rolling
