Effective Controlled Method Adding Carbon into Molten Steel to Produce 55Q Steel Tiejun Zhang1,2, a 1 Research Center for Materials Interdisciplinary Science, Chongqing University of Art and Science, Chongqing 402160, China 2 Key Laboratory of Micro/Nano Materials Engineering and Technology, Chongqing 402160, China aztj1965@tsinghua.org.cn Keywords: Cored wire, carbon adding, 55Q steel.
Second, the mission successes rate of getting carbon under control in one time is very low, thus the operation time is long, and the ineffective consumption of the devices, energy and materials is high.
There are many sophisticated physical and chemical reactions occured between the carbon and elements of materials of the furnace charge, slag and lining.

Machine learning (ML) algorithms can improve and innovate the design of new, eco-friendly composite materials.
Introduction Artificial intelligence (AI) can potentially revolutionize the experimental approach in materials science research, as AI enables the identification of hidden patterns in experimental databases, reducing the cost and time that it takes to develop new materials experimentally.
Using this optimized iterative imputer provides an accurate method to estimate values of missing data for CNC-reinforced PVA composites in material science research.
Therefore, machine learning models can significantly enhance the development and research for new environmentally friendly composite materials.

Introduction Beam methods of materials modification are being developed and implemented in industry in many countries [1-3].
It does not seem possible to avoid hydrogen penetration into materials due to large concentration of hydrogen in atmosphere or water environment, as well as due to technical conditions of materials exploitation.
However at present hydrogen influence on these materials is not sufficiently studied.

The application of modern construction in the new materials and new structure system.
With the development of modern society living and production, the growing needs of human life and production, Modern science and technology and the new building construction materials are applied to the construction of Huizhou architecture.
And the new structure form and construction materials has adapt to the life and production of modern people very well.
Besides, it’s often change materials and mode of construction between materials and materials in the construction, the safety without effective guarantee; It maybe make differences with The original process because of changing of the material size and material color ,and run counter to the principle of ancient building repair and strengthening[7].
