Research on Leveling Model of Combination Leveler Xiaogang Wang1,a , Qingxue Huang1,b and Jianmei Wang1,c , 1 Heavy machinery engineering research center of the ministry of education, Taiyuan University of Science and Technology, Taiyuan 030024, China awxg_158@sian.com.cn, bhqx@tyust.edu.cn, cwjmhdb@163.com Key words: Medium & thick plate steel, Leveling model, Combination Abstract.
The technologies of parallel leveling and tension leveling are adaptive to the roll system of combination leveler, which not only can improve leveling precision, but also can erase the influence of negative torque on leveling roll, thus improving the leveling strength capacity of leveling materials.
During this process, the overall bending deformation of material is ∑C , wherein 0CCC w −=∑ , as shown in Fig. 2(a).
During this process, if the material lies in elastic deformation period, after passing this leveling element, the residual curvature is cC , wherein fwc CCC −= , and the recovery curvature is fC , due to the pure elastic procedure, ∑= CCf , the curvature of material will be recovered to the initial curvature 0C , i.e., 0CCc = .
After passing through the leveling element, the curvature of material was called residual curvature cC , wherein fwc CCC −= , and the material would be recovered, the curvature of deformation recovery was nominated as fC , EI M Cf ∑= , ∑M is the bending torque of this bending element.

However, in contrast to conventional steel alloys, there exist little design and manufacturing experience in the heavy fabrication industry with large welded structures made of titanium materials.
In contrast to conventional steel and aluminum alloys, there exist a series of design and fabrication issues in the manufacturing industry with welded structures made of titanium materials.
The current work used two titanium materials for the plate.
In order to establish the “stress-free” lattice parameter, d0, “comb” reference specimens were produced for both titanium materials.
