This paper illustrates how systems requirements (i.e., safety) are decomposed to define manufacturing process requirements and design. Steelmaking is an energy intensive process; utilizing vast amounts of electricity, oxygen, and natural gas to liquefy scrap steel. While the electric arc furnace process is used extensively around the world to melt steel, it is inefficient. Hot gases are lost to...

Urinary 1-hydroxypyrene (1-OHP) is a biomarker of exposure to polycyclic aromatic hydrocarbons (PAH). Effect of residence on children's PAH exposure was reported among children living near a polluted area. Instead of a snapshot assessment, however, a temporal history of exposure characteristics needs to be assessed in the studies of chronic disease development such as cancer. The urinary 1-OHP ...

Urbanization is typically accompanied by the relocation and reconstruction of industrial areas due to limited space and environmental requirements, particularly in the case of a capital city. Shougang Group, one of the largest steel mill operators in China, was relocated from Beijing to Hebei Province. To study the thermal environmental changes at the Shougang industrial site before and after r...

During the continuous casting process, a nonstationary stress state forms in the metal, which is caused by a non-uniform temperature distribution, phase transitions, and the deformation of the stock in a semi-liquid state. Stresses occur also as a results of ferrostatic pressure and the deflection and straightening of the continuous casting. In addition to these phenomena, intensive processes o...

Phenomenological approach to the description of deformation resistance behaviour of steel and its microstructure development under the service hot rolling condition is still the most common useful and powerful. Utilising different experimental equipment such as torsion plastometer [1-5], compression plastometer [6-9], or advanced laboratory mills [10, 11] as well as different deformation techni...

The use of wireless applications in industrial environments is rapidly increasing. Examples are remotecontrolled cranes, doors and robots. The electromagnetic interference in such environments can cause severe problems and therefore has to be characterized to avoid accidents and disturbances in the production processes. In this paper it is shown how the measurements of the Amplitude Probability...

It is not rare to observe an inverse relationship between hot strength determined from rolling load of the finishing stands of the hot strip mill and strain. This situation was already described in the literature and is explained by the use of inverse rolling load models that assumes sticking friction in the determination of hot strength. The aim of this work was to show that this “work softeni...

A lung function study was carried out to determine the relative effect of rice husk and saw dust on mill workers. The study consisted of 195 subjects of which 56 rice mill workers, 71 saw mill workers and 68 controls of similar age, sex and socio-economic condition. FVC was significantly reduced in saw-mill workers compared to both the controls and rice mill workers. Both FEV1 and PEFR/min were...

This paper focuses on the development of a hybrid phenomenological/inductive model to improve the current physical setup force model on a five stand industrial hot strip finishing mill. We approached the problem from two directions. In the first approach, the starting point was the output of the current setup force model. A feedforward multilayer perceptron (MLP) model was then used to estimate...
