Steel is an attractive and traditional engineering material, applied very extensively. And along with the steel and iron material production modernization, current steel production has developed already from pursuing mechanical property brought by single structure to making comprehensive mechanical properties brought by multi-phases compound structure, which is adapt to high-speed of the production and meet the need of industrial development also.
The board strip is one of the important products in the steel industry used in automobiles, electrical home appliances, shipbuilding and ministry of aeronautics and astronautics industry. Its surface quality can has a direct effect on the product quality.
Research indicates, to solve the problem of the zero magnetic lakage of remanence inspection, that we can extend its application, eliminate its hidden quality trouble and inspect reliably the most dangerous defect-crack, which exist in the surface or near-surface of the steel parts.
The paper introduces the measurement principle, configuration, and main features of the laser gas analyzers based on tunable diode laser absorption spectroscopy, and presents some on-line gas analysis applications in the steel industry using these analyzers.
A PDE problem arising from calculation of the model for continuous casting of steel
This paper deals with the relationship between a certain three-dimensional elliptic problem and a two-dimensional parabolic problem, which arises from numerical calculation in the process of the continuous casting of steel.
Comparison of antibacterial ability of copper and stainless steel
In this paper, the electro-analysis and spectrophotometric analysis methods were used to study the antibacterial ability of copper and stainless steel materials.
coli) and photo-bacteria were used as samples, the antibacterial effect of stainless steel was very weak, while the percentage of bacteria dying from exposure to metallic copper for 30 min was over 90%.
