The Ministry of Metallurgy held the second national small and medium-sized mill technical transformation meeting in Beijing from November 7 to November 17, The central issue of the conference was to summarize and exchange experience in technological transformation of small and medium-sized rolling mills during the “6th Five-Year Plan” period, and to study and discuss the principles, plans and measures for technological transformation during the “Seventh Five-Year Plan” period. At the meeting, about 90 copies of the exchange materials were received. In addition to the report made by Vice Minister Chuan Dian Dian on the opening ceremony, 10 practical and practical new technologies were selected and introduced at the conference. They are: 1. High-stiffness mill for pre-stress and short-stress lines; 2. Differential speed control for continuous rolling mill; 3. Slit rolling; 4.45 ° twistless wire finishing mill; 5. Continuous rolling of narrow- ; 6 in the three-roll Lott old mill renewal and transformation for the four-roll reversible finishing mill ;. 7 seamless steel pipe single-hole oblique hole perforation process;
