Development Trend of Manufacturing Technologies for Stainless Steel Tubes Both at Home and Abroad
Abstrast: The evolution of overseas stainless steel tubes is presented
systematically, and the proceses , development trend of manufacturing technologies for stainless steel tubes toward the “three-step methods ” process steelmaking and continuous casting, hot extrusion process, cold to cold Rolling mainly cold-drawing as a supplement, organic solvent degreasing, finishing the modernization of equipment, welding + cold drawing production process, cold-drawing process of ultrasonic vibration, temperature trends both at home and abroad are analyzed in this article. Also addressed here is the gap between the domestic sector and its counterpart overseas on the said technologies involving seven aspects, namely, bloom-making process, tube hot-rolling, tube cold-rolling/drawing processes, degreasing processes, process lubrication, surface polishing. Made of stainless steel pipe technology in China should adopt the world's most advanced and mature technology of production of stainless steel seamless pipe, and actively develop high value-added and high-grade large-sized stainless steel pipe, attach importance to heat treatment and finishing facilities in the transformation of their use of the world's most advanced and mature technology of production of stainless steel seamless pipe
