The role of fluorite for converter
Fluorspar is known by many different names, it also has many different uses, but none more beneficial than in a blast furnace. A blast furnace is an extremely important tool used in steel manufacturing, as it is used to transform iron ore into useful steel elements. In order to make a blast furnac......

activated lime
Active Lime Introduction
Active lime, also referred to as burnt lime and quicklime, is a widely-used chemical compound. It is made by heating limestone to a very high temperature so that the calcium carbonate breaks down into calcium oxide and carbon dioxide. The calcium oxide, also known as quic......

Iron Slag
Iron slag is the by-product of iron production when it is heated in a furnace at high temperatures. This type of slag is usually produced in large quantities, as there is usually a large amount of iron produced at a time. Iron slag is commonly used in concrete structures and is also the ......

Abstract
Iron Losses from Desulfurization Purge Slag
In modern metalworking processes, desulfurization is one of the most important metal processing techniques, used to reduce sulfur levels in metals. During desulfurization, a special flux is poured over the metal and allowed to burn. The burnin......
Slag basicity
Slag Alkalinity
Slag alkalinity and its associated parameters are among the many processes that comprise the production of chemical and metallurgical products. The term “slag” refers to the molten material that is created during the production processes, typically consisting of an oxide or othe......
A desulfurization slag modifier
Hydrated lime is an excellent desulfurization agent .
Hydrated lime is the product of adding water to quicklime in a vague amount proportional to the exothermic reaction of the two. Hydrated lime, also called calcium hydroxide, is used in many industries to neutralize the acidity of certain subst......
Mechanism of Liming
The Mechanism of Lime Slag-making
Lime slag-making is a process which involves the chemical decomposition of lime with the help of silicon. In this process, limestone or chalk-containing compounds are heated to very high temperatures, usually around 1000 degrees Celsius. The resulting reaction is......
Gas production in molten iron pool
Iron Puddling Furnace to Generate Gas
Iron puddling furnaces have been used to produce large quantities of gas for centuries. The process involves heating and melting iron to form a liquid known as puddling. The heat of the furnace also vaporizes some of the liquid, creating a combustible gas mix......

Reducing Iron Oxide with Hydrogen
Iron oxide (Fe2O3) is a chemical compound commonly found in nature. It is typically formed by the reaction of iron and oxygen in the presence of water. It is also known as rust, due to its typically reddish-brown color. In many industries, rust is regarded as a m......
bell jar desulfurization
Sulfur dioxide (SO2) is a pollutant often generated from combustion of fossil fuels. SO2 is a major contributor to air pollution, leading to the formation of acid rain, visibility obstruction and health problems. To combat this issue, Flue Gas Desulfurization (FGD) technologies are used in many po......
