Radiographic testing
Introduction
Ray detection technology is a method of testing and detecting materials using ray radiation. X-ray technology is the most widely used technique. X-ray is a kind of electromagnetic wave of very short wavelength with higher energies than light. It can penetrate various materials and fo......
Characteristic Causes of Residual Shrinkage Cavity and Its Judgment and Treatment
Introduction
Remaining shrinkage hole is a common defect in castings, caused by a number of possible factors related to the manufacturing process. This paper attempts to thoroughly review the causes and prevention of remaining shrinkage hole defects in investment castings, and to discuss various ......
Characteristics of powder metallurgy oil-impregnated bearings
Powder Metallurgy Bearing Characteristics
Powder metallurgy bearings are capable of producing high precision and high strength products with uniform density and less porosity. Combining well-chosen lubricants with the structural characteristics of powder metallurgy bearings, such bearings can han......
Industrial Furnace Masonry
Industrial Furnace Masonry
Industrial furnaces are used for numerous industrial operations such as heat treatment, melting, or even drying of materials. In order to provide the necessary heat and thermal protection necessary for these processes, masonry is commonly employed in the construction of......
Mine Waterproof
Mine Waterproofing
Mining operations require the use of large quantities of water for numerous operations. Over time, the equipment and operations to a mine may be exposed to adverse conditions caused by the presence of water, improper drainage, and other issues. As such, it is important to ensur......
mine flood
Mining is an activity that extracts resources, such as coal and other minerals, from the earth. Mining can have a profound impact on the environment, both in terms of the destruction of natural habitats, and the release of dangrious chemicals and particles into the air and water. One particularly ......
Bubble mineralization
Bubble mineralization is a process by which mineral particles are concentrated in cavities created by the escape of dissolved minerals from shallow pockets of water into the surrounding, permeable rock matrix. This process is particularly important in the precipitation of zinc, iron, and other met......
slope stability
Slope Stability
Slope stability is an important consideration in engineering projects, such as residential and commercial buildings, roads and bridges. Slope instability causes a variety of problems, from costly delays in construction to a potential hazard for the public. Slope stability relies on......
