Zinc leaching slag treatment workshop design
Zinc Leaching Residue Treatment Workshop Design
Introduction
The purpose of this paper is to evaluate the design and operations considerations associated with the construction of a zinc leaching residue treatment plant. The plant is to be designed to process residues of zinc metal recovered from......
Differential Thermal Analyzer
Introduction
Differential scanning calorimetry (DSC) is used to measure the heat capacity of a substance and its transition temperature. This method is widely used in the field of physical properties characteristics analysis in chemometrics and quality control. In this paper, a brief overview of ......
thermodynamic state
The thermodynamic state of a system is a characterization of its observable properties such as temperature, pressure and volume. In thermodynamics, an equilibrium state describes a condition in which the properties of a system remain unchanged as a result of interactions between its components. Fo......
An example of improving the service life of extrusion dies after gas nitrocarburization
Example of Nitrogen Hardening to Increase the Service Life of Squeeze Molds
To achieve the low friction, tight tolerance and long service life of squeeze molds, nitrogen hardening is a process in which nitrogen is used to improve the mechanical properties of the tool. With the use of this techniq......
Tempering treatment
Heat Treatment
Heat treatment is a process used in materials engineering and metallurgy to change the physical properties of metals and alloys. Treatments include annealing, hardening, stress relieving, normalizing, tempering, and quenching. Heat treatment is used to improve or alter the mechanic......
heat generation of reacting species
Thermal generation of reacting substances is the process of converting energy from one form to another, and it is a vital part of many industrial and scientific processes. This process occurs naturally in many forms, including thermal expansion, chemical oxidation, and thermochemical reactions. A......
surface hardening
Surface Hardening
Surface hardening is a process of hardening the surface of a metal, usually a low carbon steel, by infusing elements into the material’s surface, forming an ultra-hard surface layer, while the core remains relatively soft and malleable. The purpose of surface hardening is to im......
chemical heat treatment
Heat treatment is a process that is used to change the physical and chemical structure of metals and alloys. Generally speaking, heat treatment involves heating and cooling metals or alloys to obtain desired properties. Heat treatment is one of the most important metallurgical processes used to m......
Metal heat treatment quality control
Metal Heat Treatment Quality Control
Heat treatment, or thermochemical processing, is an important process in metalworking. It is used to alter the properties of a metal such as hardness, ductility and strength. Heat treatment is widely used in various industrial processes such as automotive, pow......
