Vickers hardness value of commonly used sheet metal
Materials of the World: Vickers Hardness Values
Vickers hardness is the measure of a materials strength and resistance to penetration. It is a measure of the metals resistance to wear and abrasive wear, as well as its ability to retain its shape under an applied force. In addition, Vickers hardne......

Absolute Grindability
Absolute Grinding Hardness
Grinding hardness is a measure of material’s hardness or the ability of material to resist grinding by abrasive forces. Grinding hardness is most commonly measured when working with metals. Grinding hardness is the ability of a material to resist grinding contact and t......
Sodium carbonate leaching
Sodium Carbonate Extraction
Introduction
Extraction is the process of separating an organic compound from a solution. One example of an extraction is sodium carbonate extraction from brine, which is a by-product of terrestrial and marine evaporation processes. Sodium carbonate, or soda ash, is i......
Lithium slag treatment
Lithium slag (LS) is a process residue that is derived from lithium production in industrial settings. The process of obtaining lithium involves the extraction and concentration of lithium-rich brines followed by the conversion of lithium compounds and finally, the heat treatment of the purified c......
Process water for steel production from seawater - efficient use of energy
Harvesting Steel Production Water from Sea Water: Optimizing Energy Usage
Steel production requires a tremendous amount of water, and typically steel manufacturers must access freshwater resources to meet their needs, a resource which is becoming scarcer in many parts of the world. Fortunately th......
Graphite sulfuric acid dilution cooler
Graphite-sulfuric acid dilution cooler
Graphite-sulfuric acid dilution coolers (GSDCs) are efficient and affordable cooling methods often used in chemical and petrochemical plants. They are used to reduce process temperature and/or to maintain temperature at certain levels, enabling efficient hea......
Example of heat treatment: heat treatment of curved parts (below)
The second step in the process of heat treating an automotive part is to ensure the correct cooling rate. After heating, the part needs to cool at a rate that will produce the desired impact strength and the most consistent across the entire part. If the cooling rate is too slow, it can cause warp......
3 ways to check bearing clearance
1. Method of Thermal Extension: This method is also called thermal expansion or hot alignment method. It requires to heat the shaft and its bearings to a pre-determined temperature value, usually 250℃ to 350℃ , and then measure the distances between the shaft and bearings with a suitable shaft p......
