What is the concept of Pipes pointed cusp shaped pipe, rectangular pipe, the pipe deformation mechanism in Turkey, the first four roll centerline of the tube cross section, Zaozhuang hexagonal steel pipe, rectangular pipe sharp mechanism and the rectangular tube is formed by ordinary bent at an angle is different, it relies on the rolls rolling force, compressive force F generated by arch arc, shown in Figure 2, the corners of the steel strip plastically deformed so profiled steel, rectangular tube, square Tube filling the corners together. Diagonal filling pressure arc arch Turkish first four roll at a certain cross-section of the arc acting on the same strip, conditions Jingzhou hexagonal steel pipe, satisfies the equation (1), it can roll pressure through the corner of the metal to plastic deformation form sharp corners. 3. Calculation shaped steel ⑴ gross weight is "Net" symmetrical, the total weight of the steel itself and packaging materials combined. Transport enterprise computing gross weight when calculating shipping. But buying and selling steel material is calculated as net weight. ⑵ Net is symmetry "Gross" is. Steel gross weight minus the weight of packaging materials after that the actual weight, called net. Generally calculated according to net buying and selling of steel. ⑶ shaped steel tare weight of the package, called tare. ⑷ weight tons gross weight by unit of weight of steel used when shipping. Its legal units of measurement tonnes (1000kg), as well as long ton (imperial unit of weight 1016.16kg), st (US system of weights 907.18kg).
