The experiment and the research indicate that:(1) Through the Hot-Continuous-Rolling production technics under small reduction ratio of 4.04 and 5.08, the rectangular continuous-casting billet of 235×265mm can be used to produce big size steel stick of Φ140mm and Φ 125mm whose macrostructure and mechanical properties meet the standards, this technics is viable;(2) This rolling technics can make the deformation penetrate to the center of the billet by low temperture and low velocity and big roller diameter and large reduction quantity at every pass and optimum design and arrangement of rollers, which is the key of Hot-Continuous-Rolling technics under small reduction ratio;(3) The sending technics used in Xining Special Steel Co.,Ltd can not use waste-heat of billet adequately, but the sensitive temperature section of A1N or sulphides or inclusions separating out is avoided, creating a favorablecondition for insuring good surface quality of final rolled steel;(4) The Hot-Continuous-Rolling technics under small reduction ratio has a close relationship with the billet quality control and the hot sending process control and the cooling control after rolling.

The main contributions of the paper are as follows:(1) The paper expounds the characteristics of power transmission of EHV and UHV six-phase transmission lines. Researching results show that six-phase can utilize the overhead transmission right-of-way efficiently, and improve the density of power transmission. At the same time, the electric field on surface of conductor, the power frequency electric-magnetic field at ground level can be controlled within the range of permission for six-phase transmission lines.

Finally, the integration of RP technology and RE is deep investigated. Some problems related with surface model and RP technology is pointed out. The method and data structure of reconsfructing the topology information of STL file are proposed. Also addressed in the paper are issues of the mistake check methods and repairing techniques of STL file. Then an experimental procedure of creating interface file and making the seat prototype of a bike is summarized in detail. The result testifies the feasibility and practicability of the technical line presented in this paper. All of the above-mentioned measures, impact the development for realizing the integration of RE/RPM.
