Metallurgical Fluorspar

Description

In the process of iron and steel smelting, in order to remove impurities such as phosphorus and sulfur. Resulting in good slag with good reactivity. Need to add metallurgical flux such as limestone, lime or Fluorspar. Metallurgical Grade Fluorite, also known as fluorspar, has a main chemical composition of CaF2. There are crystals of various colors such as yellow, lilac, rose, green and black. Metallurgical Fluorspar Specific gravity 3.2, melting temperature is about 935 ℃.

Metallurgical Fluorspar Uses

 
According to the wiki of Fluorite. There are three principal types of industrial use for natural fluorite, commonly referred to as "fluorspar" in these industries, corresponding to different grades of purity. Metallurgical grade fluorite (60–85% CaF2), the lowest of the three grades, has traditionally been used as a flux to lower the melting point of raw materials in steel production to aid the removal of impurities, and later in the production of aluminium.
 
Ceramic grade fluorite (85–95% CaF2) is used in the manufacture of opalescent glass, enamels, and cooking utensils.
 
The highest grade, "acid grade fluorite" (97% or more CaF2), accounts for about 95% of fluorite consumption in the US where it is used to make hydrogen fluoride and hydrofluoric acid by reacting the fluorite with sulfuric acid.

In the blast furnace, Fluorspar CaF2 is used for washing the furnace (by lowering the melting point to remove nodules on the furnace wall).
 
Metallurgical Fluorspar has the effect of lowering the melting point of high melting point materials, promotes slag flow, and enables slag and metals to be well separated. Desulfurization and dephosphorization in the smelting process, enhance the metal's calcinability and tensile strength and other characteristics. Therefore, it is widely used as a flux in iron and steel smelting and ferroalloy production, chemical iron process and non-ferrous metal smelting. Fluorspar mineral for smelting generally requires CaF2 content greater than 65%, and also has certain requirements for the main impurity SiO2. There are strict restrictions on S and P, and the content of S and P should not be higher than 0.3% and 0.08%, respectively.

Metallurgical Fluorspar for Converter Steelmaking

Metallurgical Fluorspar is the most commonly used flux for converter steelmaking. It has an obvious effect on lime melting and slag dilution, and the slag is quickened and the amount used is small. Fluorspar CaF2 has strong corrosiveness after decomposition, which seriously corrodes the furnace lining. It is unfavorable to equipment and furnace lining, and it is also easy to cause environmental pollution. The amount of use should be properly controlled. Coupled with the limited resources of fluorite, insufficient supply and high prices. For many years, metallurgical workers have been looking for alternative materials for fluorite. fluorspar suppliers in pakistan.

Converter Steel Slag Replaces Limestone and Fluorspar as Flux

 
Open-hearth and converter steel slag wastes replace limestone and Metallurgical Fluorspar as iron-making fluxes. In foreign countries, it has been adopted since the 1950s. The utilization rate of steel slag in the United States reached 100% in 1977, and more than half of them were used as ironmaking fluxes. 42% of the steel slag from West Dyssen Steel is used in ironmaking fluxes. In recent years, Canada, Western Europe, and Japan have all adopted new technologies for the comprehensive utilization of steel slag instead of flux materials, and have achieved greater technical and economic effects. According to the composition of steel slag and its physical and chemical properties, and the use of blast furnace. We believe that the use of steel slag flux is also possible. fluorspar price in india.

Metallurgical Materials Supplier

 
In the iron and steel smelting process, in order to remove impurities such as phosphorus and sulfur, resulting in a slag with good reactivity and an appropriate amount, metallurgical grade fluorspar fluxes such as limestone, lime, or fluorite are required. In order to control the temperature of the molten steel not to be too high, it is necessary to add a coolant such as scale, iron ore, sintered or limestone, etc. In order to remove oxygen in molten steel, it is necessary to add deoxidizers such as ferromanganese, ferrosilicon and other ferroalloys. The above materials are collectively referred to as auxiliary Metallurgical Materials. Metallurgical Materials Supplier not only Metallurgical Fluorspar supply, also providing high-quality metallurgical auxiliary materials, such as refining slag, high-quality Graphitized Carbon Raiser, magnesium ball, covering agent, etc.
