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 ...
A recent advance in corrosion-resistance technology overcomes the problem of steel corrosion in CO2enriched environments. At an inhibitor concentration of 10 M, the inhibition efficiency exceeded 98% where the steel corrosion rate is decreased by a factor of at least 100.
In the paper we rewiev the experience with the steel from Cold Rolling Mill Kraluv Dvur near Prague, where the steel for barrel module 0 prototype of the TILECAL calorimeter was fabricated. The measurements of the tolerances, mechanical properties and the chemical composition are presented.
The justification and economics of the operational animal damage control program in California as conducted by the U.S. Fish and Wildlife Service are discussed. Emphasis is given to the necessity for use of the steel trap. Nearly 83 percent of the depredators are taken by trapping. Annual agricultural losses due to predation were estimated at $4.7 million in California for Fiscal Year 1975. The...
