Table 1 Three kinds of surface treatment for experimental study Sample Numbering Testing Material Treatment Process 1 TiN Physical vapor deposition 2 Nickel tungsten Brushing electroplating 3 hard chromium electroplating 4 SKD61 No coating Figure 1 stripping performance testing platform Figure 2 stripping performance histogram 3.2 Surface topography analysis of coatings For the purpose of mastering the surface microstructure and topography’s effect on stripping performance between coatings and molten PC, we observed by SEM surface topography, microstructure and 3D shape of the second phase between brushing plating nickel-tungsten and electroplating hard chromium respectively in figure 3 and figure 4.
Hard chrome plating apparently held rough micro-structure, coarse grains, and overall peaks and troughs, which caused a larger flow resistance for PC and poor stripping performance between them.

This results in a variety of crystal defects such as dislocations, vacancies, stacking faults and an increased number of grain boundaries.

In the "eleventh five-year plan" , Ministry of science and technology put forward the scientific support plan "a new generation of circular steel process technology" project based on China's existing and the caofeidian steel enterprise to implement technology renovation project, to develop the large coke oven energy efficient conversion technology, super large blast furnace system technology, and the molten iron pretreatment technology, high speed continuous casting, dry deducting, dry slag graining, waste heat recycling and other great technology and key technology of energy conservation and environmental protection to improve the technology and equipment level of our steel enterprise.
Conclusions After the study, it is not difficult to find, although in recent years a number of new technologies emerged, but few can be popularized, it can’t meet the development of the steel industry by traditional technology improving and way with single technology.

However, it is difficult to get satisfied regeneration sand using the traditional mechanical and pneumatic regeneration because that the resin coating on the surface of alkaline phenol formaldehyde resin bonded sand has a certain toughness, and there is a large number of used sand abandoned, resulting in environmental pollution and waste of natural resources, which may restrict the promotion and application of the alkaline phenol formaldehyde resin bonded sand process.
It can be seen from Table 2, the shape factor of the sand is not significantly affected by a variety of regeneration methods and the sand grain shape is not subjected to baking and mechanical regeneration.

From the XRD results, it was concluded that the presence of mineralizer in the reaction medium had an effect on the interplanar distance, grain size as well as strain and crystalline quality of the as-synthesized materials.
It clearly depicts that large numbers of one dimensional (1-D) rods distributed homogeneously and their ends typically look the hexagonal cross section.

All diffraction peaks can be indexed as the hexagonal structure of magnesium hydroxide (JCPDS .le number 7-239).
The significant broadened peaks indicate that the magnesium hydroxide particle has very small grain size．And there are not any additional peaks showing that the magnesium hydroxide sample has high purity.

In addition, XACML is able to adapt to various application environments, supports wide data types and rule combined algorithm, and it also can be used to describe all kinds of complex and fine-grained access control security requirements.
DecisionResult=false; for(i=0:inumber of rules, namely it equals as: E.

If these tasks contain only a simulation activity, then these will bring a lot of operational inconvenience, so each simulation type should be divided into a series of fine-grained tasks, which constitute sub-process as part-level processes .
Parameter is the initial parameters and its' value, different Components have different number and type of parameters.

Then adding PVA solution , AgNO3 and H2C2O4 successively in distilled water , the Ag2C2O4 dispersion of white precipitation can be obtained .Through adjusting the dosage of PVA aqueous solution in so far as 3ml-8ml, the white Ag2C2O4 precipitation dispersion can be got numbers A to F in turn .
And the grain boundaries could be observed obviously in the interior of the lamella particle.

As the steels were developed for structural applications, a great numbers of concepts established for steels can also applicable to other materials that has structural applications.
The relationship between strength and microstructure of these materials can be summarized as follows; sy(Yield Strength(MPa))= sy0 + Ky (l-m)- Kp (P-n)+Kd(d-q)...... (1) where l is the interlamellar spacing, P is the colony or nodular size and d is the parent phase grain size before transform to the lamellar structure; m is 1/2 here and the equation is based on a Hall-Petch relationship.
