The concept and application of carburizing agent
Abstract
The concept of permeation carbon and its various applications are discussed in this paper. Permeation carbon is a type of carbon that allows organic vapors to permeate through it. This process is used in a wide range of applications, including gas separation, adsorption, and chemical rea......

Material Selection of Finishing Stand Rolls
Roll Application
The purpose of the roll determines the material and design selection for the roll. In a rolling mill, the rolls are required to deform the incoming material to reduce its cross section and obtain the desired shape, size and surface finish. Rolls are made from a variety of materia......
reverse solidification
Inverse Hardening
Inverse hardening is a type of tempering that is used to make tools and other metal products more durable and strong, while increasing their resistance to wear. The process is also sometimes known as reverse annealing. Inverse hardening acts by selectively hardening the surface o......
Immersion continuous casting

Immersion Casting Process
Immersion casting, also known as “directional solidification casting”, is a casting method that utilises the combination of cooling and gravity forces to create objects which are cast with superb precision and considerably decreased lead times in co......
Oxygen-enriched smelting
Oxygen enriched smelting is a technology used in the steelmaking process that uses high levels of oxygen injection to improve the level of metallurgical efficiency. The process is a form of indirect smelting, whereby the oxygen injection supplies additional energy, as well as enhancing the oxidati......
separation factor
Separation coefficient
Separation coefficient is an important coefficient used to predict the fraction of an analyte that would be present in a given phase of a two-phase system. Separation coefficients are generally determined through chromatographic, but they can also be used to indicate the d......

Hydrogen Production Through Oxyhydrogen Refining
Hydrogen is an essential element in the modern world, used in the production of many everyday items. It has found use in the production of fertilizers, fuels, pharmaceuticals, and more. While it may not be immediately obvious, hydrogen also has a c......
Ways to reduce sulfide inclusions in steel
The Approach of Low Desulfurization of Steel
The composition of steel usually includes an element called sulfur, which can do a great influence on the structure and performance of the steel. To control the sulfur content of steel is the first step for the stability of steel quality and performanc......
Refining process outside the furnace
Metallurgic Refining Processes
Metallurgic refining processes are used to purify metals from unwanted elements in ore or other impurities. Refining typically involves separating the desired metal from other metals, minerals, or unwanted elements by heating the ore to a high temperature, often melt......
Liquid steel vacuum lifting degassing method
Vacuum lifting deaeration method for steel liquid
The manufacture of steel products usually involves the melting of steel in a liquid form. After a careful selection of raw materials, the steelmaking process starts by heating the raw materials in a furnace and then transferring the molten steel t......
