[黑色金属冶炼和压延加工业,建筑业] [2014-03-28]
This paper proposed a hierarchical architecture of steel house materials. The proposed architecture will include the detailed information of the components. For this, we made description about steel house design method and material change task ontology. Especially AFM is composited with total four steps. Using the method, the solution process of possible problems occurred in a steel house can be converted to an otology. Also we made category about composite patterns of steel house materials.

[黑色金属冶炼和压延加工业] [2014-03-27]
In order to verify correctness of two-dimensional axisymmetric finite element model,this paper carries out axial symmetry analysis of the steel ball shell by ANSYS software and 2-D finite element model is established.The radial and tangential stress distribution is acquired,through comparison with the theoretical solution,both are in good agreement.So it is feasible to simulate the three-dimensional model by finite element axisymmetrical two-dimensional model.

113.冷却过程中钢板的材料模型
[黑色金属冶炼和压延加工业] [2014-03-27]
The time-dependent inhomogeneous temperature distribution in steel plates during the cooling increases thermal-strains which,in turn,generate plastification and thus residual stresses.Moreover,phase transformation from the parent austenite phases into a product phase typically entails not only metallurgical strains but also accounts for transformation induced plasticity (TRIP),which again generates transformation related residual stresses.A unified material model that consisting of all relevant contributions to the total strain rate,i.e.,elastic,plastic,thermal,metallurgical and TRIP strain contributions could be built in this paper.

115.表面渗铝氧化处理后8407钢的抗熔损性能研究
[黑色金属冶炼和压延加工业] [2014-03-27]
The melting-loss properties of specimens with aluminization and oxidation treatment and without treatment in liquid aluminum alloy of ADC 12 under rotation condition were evaluated by weight loss method.Sample surface conditions were observed by digital camera and microstructures of sample cross sections were observed by metallographic microscope after melting-loss test.Finally,the anti-melting-loss mechanism of oxide film under dynamic condition was clarified.The results show that the formed Fe3O4·Al2O3 film can improve dynamic melting-loss resistance due to isolating steel substrate from liquid aluminum.

[黑色金属冶炼和压延加工业] [2014-03-27]
To obtain fatigue design data of the train wheel steel,the fatigue tests were carried out for the steel of K type and B type train wheel separately,which fatigue limit was measured using the fluctuation method,the fatigue life of two kinds of wheel steels were tested using the grouping method at the three stress levels,two different materials and different structures have an influence on the fatigue properties of the wheels using reliability principle.The fatigue life distribution of the B type is scattered relatively.S-N curve equation and P-S-N curve equation of the two kinds of steel were calculated.The theoretical basis were put up for developing design standards and safety evaluation of the both wheel.

[黑色金属冶炼和压延加工业] [2014-03-27]
The researches of non-oriented silicon steel are mainly focused on the effect of main processing parameters on the microstructure and magnetic properties,but there have been few studied about its flow stress until now.In this paper,the hot deformation of non-oriented silicon steel 50A1300 is studied by thermal-mechanical simulation method.The hot deformation behavior of the steel is explored and the flow stress prediction of the steel is established based on a kind of BPA ANN.A piecewise method is proposed in this paper,and the prediction with this new method has good accuracy.

119.基于双场检测的带钢表面缺陷检测的自适应预处理方法
[黑色金属冶炼和压延加工业] [2014-03-27]
A new Processing flow is put forward. Firstly, the suspected defect images are filtered out, and only the images that contain defects can be processed in the follow programs. Secondly, the retained suspected defect images are divided into two categories. Different categories are handled by different process. The simulation experiment result shows that: it not only makes full use of the advantages of the double field method, and greatly reduces the image data quantity, at the same time ensuring the real-time of the system.
