Introduction In past decades, preferences of international iron-ore trade markets have moved to low-phosphorus iron ores because of the well-known detrimental effects of phosphorus on steel and other iron-related materials [1, 2].
Raw material samples were putted into different quartz crucibles with a corresponding number.

Through the refining of materials, we find that setback has a more specific effecting way compared with traditional factors.
Conclusion and Suggestions Research Conclusion 1）Through the analysis of materials, we can know that, unlike traditional factors, setbacks’ influence on female growth can be divided into two stages.

On the supposition that there is clearance and use of steel materials.
Shows the relationship between contact force and the velocity of different k(x (1.0E+005)) Stiffness K value is the comprehensive value in contact with two constructional elements ,which is comprehensively influenced by the rate of adherent point and elastic modulus .In theory, the K value can be calculated to use the above formula.It can be seen from the chart above that contact force declines with material rigidity coefficients declining and when one of two material elastic modulus is lesser,the change of the other material rigidity coefficient has no effect on contact force,as is showed that,through rational choice of materials(make a material elastic modulus is low),it can can achieve the purpose of reducing contact force (such as reflector materials use high strength engineering plastic).Certainly, the material selection need also take into account the density and intensity.
