the demand of the automobile industry, machinery industry , real estate industry and electrical home appliances industry have great impact to the steel market demand, the highvalue-added products used in these four industry will occupy about 80 percent of the total amount of the steel market demand.
Cryomilling machine which can work in liquid nitrogen was designed and refitted. Cryomilling of FeAlx, (Fe0.94Ti0.o6)Alx and(Fe0.94B0.o6)Alx (x=l,3) have been performed in refitted highenergy plant ball mill for different milling time.
Iron & steel products market is a market of producer's material and the industry of steel & iron is the upriver industry of elemental establishments instruction, the industry of real estate, machine, appliance wirings that are very important in national economy.
Taking the main exhauster of the Sintering Plant of Xiangtan Iron &Steel Co. as an example, on-line monitor, fault diagnosis technology and application in situ of the excitation control systems of large rotary machines and synchronous motors were presented.
This system uses various feedback informations from in the running process of machines and electric equipment etc, through adjudging made by the special software, to determine the location and causes of trouble and provide the methods for troubleshoot.
The application of Auto CAD to the calculation for tilting moment of melting equipments makes the calculation process more simple, convenient and precise. This method can be further applied to design the parts of rotation machines in all industries.
A sample pretreatment microfluidic chip was described based on the principle of solid phase extraction and micro electro mechanical system technology.
The copolyimides were characterized by Infra-red (IR), Nuclear Magnetic Resonance (NMR), Gel Permeation Chromatography (GPC), Ultraviolet Visual (UV-Vis), Thermogravimetic Analysis (TGA) and Dynamic Mechanical Analysis (DMA).
Effects of relative content of HTPB and PPG on emulsion stability, resistance to water and ethanol, thermal stability, compatibility of soft and hard segment, as well as the mechanical property of the cured film were investigated.
The result indicates that Si-PU exhibits good surface and mechanical properties when the DHPDMS content is 5%.
The effects of PU molecular weight on the mechanical properties and thermal stability of the PU/PVC materials were investigated.
The results, based on the dynamic properties calculation of a typical mechanical spiral seal, such as stiffness coefficients and damping coefficients, exert the influence of the mechanical seal on the rotor-bearing system of the high-speed machinery.
In addition, the machinery fault data were analyzed by this method, and the attribute reduction sets were obtained further to satisfy the demand of feature selection in machinery diagnosis.
The fault diagnoses during the speed-up and speed-down processes for rotating machinery have been successfully completed.
But dynamic nanostructure and bio-machinery that depend on collective behavior of biomolecules have not been demonstrated.
In consideration of the needs of human beings, machinery and computation, the model has been used for structural design combined with relevant knowledge, means, maneuver and strategy.
