The purpose of the tests was to determine whether and how sterilisation process of samples made of AISI 316L stainless steel with diff erent strain impacts their corrosion resistance. Tests were made on steel samples that had been electrochemically polished in order to assure proper surface roughness. In order to evaluate the infl uence of sterilisation on physical and chemical properties of st...

Investigations on flexural and tensile properties of GFRP laminates influenced by stainless steel wire reinforcement were carried out as a novel approach. Plain GFRP laminates and GFRP laminates reinforced with stainless steel wires at different depth with various pitch distances were fabricated by hand layup method. The composite specimens reinforced with steel wires were exposed to low freque...

Although the Steel Mill Slab problem (prob 38 of CSPLib) has already been studied by the CP community, this approach is unfortunately not used anymore by steel producers since last century. Continuous casting is preferred instead, allowing higher throughput and better steel quality. This paper presents a CP model related to scheduling of operations for steel making with continuous casting. Acti...

The NIST Construction Metrology and Automation Group, in cooperation with the NIST Intelligent Systems Division, is researching robotic structural steel placement as part of a project to develop an Automated Steel Construction Testbed. This project was initiated in response to industry requests for advanced tools and methodologies to speed the erection of steel structures while maintaining or e...

There are over six hundred thousand bridges in the U.S. which require great amount of human effort along with expensive and specialized equipment for maintenance. Current bridge inspections are manually performed by inspectors which are inefficient and unsafe. This paper presents visual and three dimensional (3D) structure inspection for steel bridges and steel structures using the developed cl...

Manufacturing execution system (MES) is a bridge that connects the top layer of planning and the bottom layer of control. In integrated automation system (IAS) whose structure is 3-layer BPS/MES/PCS, MES is the key circle to realize the integrating of integrated automation system in iron & steel enterprise. According to the characteristics of production management in iron & steel enterprise, th...

M. Torres-Lopez, L. Guerra-Fuentes, L. Y. Gomez-Zamorano, M. A. L. Hernandez-Rodriguez, E. Garcia-Sanchez. University Autonomous of Nuevo Leon. Thermal analysis in a PREMOMET® steel has been performed by differential scanning calorimetry (DSC) and highresolution dilatometry. The phase transformation temperatures (Ac1, Ac3, Ms and Mf) of this steel were obtained by the two methods at different h...

A method using electropulsing to separate inclusions from molten steel is developed, based on the differences in electrical properties between the inclusions and liquid metal. The inclusions have different electrical resistivity from that of the liquid steel and hence being expelled to the surface of the metal by electropulsing. In comparison with the as-solidified untreated steel, the size of ...

the effect of steel plate thickness on the repair effectiveness of rc beam is presented in this paper. a total of four beams were tested, one beam repaired by cfrp with a thickness of 1.2 mm and used as a control beam, and three beams repaired by a steel plate. steel plates with a thickness of 2 mm, 3 mm, and 4 mm were used in repairing the beams. the maximum load-carrying capacity, deflection ...

Steel corrosion leads to the deterioration of bond between concrete and steel bars. The serviceability and ultimate strength of concrete elements within RC structures are hence affected. Many researchers have studied the bond behavior of corroded steel bars. However, very few studies have investigated the effects of confinements on the degradation of bond strength. The present paper proposed a ...
