Casting Steel Ingots by Foundry Casting
Foundry casting is a process used to shape and solidify molten metal into ingots. This technique has been in use since ancient times and is still widely used today in a variety of industries. Foundries use a variety of different melting and casting techniqu......
The amount of fluorspar used in converter steelmaking slag
Overview
Bauxite is widely used in the steelmaking industry to produce high-quality steel. The use of bauxite as an additive helps to significantly improve the properties of the steel being produced. It is a commonly used material, but can sometimes be expensive to purchase. Therefore, manufactur......
Using CO Concentration Curve to Monitor Converter Slagging
Introduction
Iron-making is an important process for the steel industry, and coke is the main raw material . Coke oven gas (COG) is a by-product of coking during the iron-making process and is composed mainly of CO and H2. The proper control over the coking process is important to ensure that the......
Formation of foamy slag and its influence on blowing and its control
Formation of Slag and Its Impact on Blowing and Control
Slag is a material that is produced when certain ores are melted and the impurities are separated. It consists mainly of oxides of phosphorus, silicon, aluminum, iron and magnesium, and solidifies in the furnace, forming a layer on the air f......
Reasonable control of sulfur content and corresponding steelmaking production process
Control of Sulphur Content and Relative Steelmaking Process
Sulfur is an unavoidable element in steel due to the content of rust in iron ore, but at the same time too much sulfur exists in steel, which will make the toughness of steel effectively reduced and even lead to some serious problems suc......
Contents of silicon, phosphorus and sulfur in hot metal triple removal pretreatment
！
Introduction
In the metallurgical production process, the steel three deslagging is an important key link before steel smelting process. It can not only effectively reduce the silicon, phosphorus and sulfur content in molten iron, but also reduce impurities and improve the quality of molten ir......
Principles for Determining the Loading Quantity of Converter
The Principle of Determining the Loading of a Blast Furnace
The blast furnace is a self-heating type furnace, which is used to smelt iron ore into pure iron. It is the most important equipment for the production of iron and steel. The loading of blast furnace directly affects the production effic......
Bottom Electrode Composite Brick for DC Electric Arc Furnace
DC arc furnace sole electrode composite brick
DC arc furnace sole electrode composite brick is a new type of refractory material developed and applied in modern industrial furnace. Compared with traditional sole electrode, the composite brick provides more reliable sealing performance, easier op......
Iron loss factors during slag removal after desulfurization
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......
