Heat treatment development history and technology application
The Development and Application of Heat Treatments
Heat treatments are a process used to alter the physical, chemical, or metallurgical properties of a material or workpiece. This is done by heating the material or workpiece and then cooling it back down in a controlled manner. It is helpful to u......

Common Defects of Nitriding (Soft Nitriding)
Leakage of N2 in NF3 Etching
As the need for complex semiconductor wafers and advanced packaging technologies continues to grow, so does the need for sophisticated high-throughput chemical etching processes. Nitrogen trifluoride (NF3) is a key etchant used in the semiconductor industry, as it is ......
Mechanism of contact fatigue spalling
Fatigue of metals is one of the most important failure mechanisms in engineering. Tensile tests have been used to study the fatigue behavior of metals. The reduction in load-recycling load ratio, or the fractional toughness, can be used as a measure of fatigue strength. The fractional toughness is......
rotary forging
Introduction
Spin forging is a forming technology for metal components that involves forming a heated semisolid material that is between a liquid and a solid. The process involves pressing and spinning a heated material into the desired shape and size as it cools and solidifies. Spin forging has ......
Process performance test
The plasticity of a material is an important physical property that is necessary for the manufacturing of plastic parts. It can be defined as the ability of a material to deform under stress and return to its original shape when the stress is released. The degree to which a material can be plastic......
The role of molten steel and refractories in continuous casting
In continuous casting, steel liquid and refractory materials play a very important role. Refractory materials are essential to continuous casting, and the quality of their performance directly affects the quality of continuous cast billets and the normal production of the plant.
The role of refra......
Oxygen combustion fluxing technology
Introduction
Oxy-fuel combustion technology is one of the most energy efficient and cost effective combustion technologies available today. It combines the combustion of oxygen and fuel to produce temperatures high enough to melt or refract metals or other materials. This technology has a wide ra......
Causes of converter lining damage
Cause of Damage to Blast Furnace Lining
Furnace lining is a vital component of the blast furnace due to its protective nature. It helps to contain and protect the steelmaking atmosphere inside the furnace, making it an important component of a steel plant. It is often subjected to extreme conditi......
Brief Introduction of Neural Network Model for Sinter Performance Index Prediction
Introduction
Very recently artificial neural network (ANN) models have been gaining immense popularity for predicting the properties of pelletized iron ore. Neural networks are a type of machine learning model which imitate the processing of data in a human brain and are used to predict the desir......
Blast furnace gas distribution
Distribution of Blast Furnace Gas
Blast furnace gas is a byproduct of the steelmaking process. It is produced when iron ore and other materials are heated in a furnace to create molten iron. Gas is collected at the top of the furnace, and is used as a power source and to reduce energy costs.
