【Abstract】 In this paper, the technology and equipments for producing stailess-steel composite tube with drawing-composite process are introduced. If the mould angle is 10°-15°, the sizing reduction is less than 8 times the tube-thickness, and the lubricant prepared by ourselves is used, the problems of the sizing reduction unstability and the lubrication in drawing-composite production can be solved. The advantages, the disadvantages and the technical economy indexes of the drawing-composite process are compared with these of the cover welding process.更多还原
