Abstract Considering the problem of high oxygen content in industrial niobium powder, reduction powder with addition magnesium is studied. Based on thermodynamic analysis thermal effects temperature, addition, time, and atmosphere pickling are The results show that an increase gradually decreases to a certain value, then remains unchanged. In temperature range (953–1203 K), first decreases, inc...

Nanostructured iron oxide powder that has been recovered from waste pickling liquor unit of steel industry was studied for oxidation catalytic applications. In this research, the powder was characterized by X-ray diffraction (XRD) and transition electron microscopy (TEM) for determination of phase structure, morphology and particle size. Furthermore, the specific surface area of the powder was ...

The cucumber pickling industry has sporadically experienced spoilage outbreaks in pickled cucumber products characterized by development of red color on the surface of the fruits. Lactobacillus casei and Lactobacillus paracasei were isolated from 2 outbreaks of this spoilage that occurred about 15 y apart during the last 3 decades. Both organisms were shown to produce this spoilage when inocula...

Virtually all products that are finished require some pre-finishing procedure such as cleaning, stripping, or pickling. Without a properly cleaned surface, even the most expensive coating will fail to adhere or protect the workpiece. Depending on the process being performed, the degree of cleanliness will vary. Finishing operations such as phosphating, chromating, or electropolishing do not req...

The Spring1 system does not provide persistent object identifiers and not all Spring objects are persistent. Instead, we rely on a general name service and persistent name-to-object bindings to support persistence. The name service is separate from the various subsystems that implement persistent objects, so that new object types can be added, and the implementation of existing types can be cha...

Gold alloys with Cu contents of 10 mass%, 20%, and 30% were used for morphological observation of porous surface structures after heating at 800 degrees C in air followed by pickling with acid solution. With increasing Cu content in the gold alloy, the internal oxidation zone became well-developed in the alloy matrix. The mechanism by which a porous structure was formed on the surface of a gold...

The objective of this research is to study plant layout of NCRM (Narrow cold rolling mill division) of Bhushan steels Ltd. Mumbai based on the systematic layout planning pattern theory (SLP) for increased productivity. In this case study, amount of equipments and tools in rolling coil production are studied. The detailed study of the plant layout such as operation process chart, flow of materia...
