Advantages and disadvantages of hot metal pretreatment with three de-siliconization, dephosphorization and desulfurization
The Three Aim degassing Process of Iron Working
Introduction
The three aim degassing process of iron working involves degassing, dephosphorization and desulphurization of molten iron. This process is often done to improve the quality of the metal and to increase productivity by reducing the amou......
Purification outside the melt furnace
Purification of Melt Bath by External Purification Method
Introduction
Metal purification using an external purification technique is a process of removing unwanted impurities from the surface, body, and/or components of molten metals. This method involves the use of inert gas, liquid or solid p......
Large non-metallic inclusions in steel ingots
Nonmetallic Inclusions in Bulk Steel Ingots
In the production of steel alloys, nonmetallic inclusions can cause various production problems and limit the properties of finished alloys. These inclusions can form in steel during the melting process and through their accumulation during solidificat......
Liquid steel vacuum treatment
Advantages of Vacuum Processing Steel Liquid
Vacuum processing of steel liquid has become the mainstream processing method of modern steel production and smelting. It is also suitable for stainless steel and alloy steel heat treatment. Vacuum processing of steel liquid has many effects which c......
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......
Vacuum degassing of molten steel
Vacuum degassing is a process under low pressure and high temperature conditions to remove hydroxide, hydrogen and other dissolved gases from molten steel in order to reduce the emission of harmful gases. This process is also known as vacuum dehydration and deoxidation.
The main task of vacuum de......
Molten steel vacuum circulation degassing method
Vacuum circulation degassing of steel liquid
Steel deoxidization and desulphurization often requires a quick and effective removal of oxygen and sulfur from the steel.This process is known as degassing.At present,the most widely used degassing method for steel-making is vacuum circulation degassi......
Characteristics of Oxygen Jet Movement in Multi-hole Nozzles
Introduction
Multi-nozzle oxygen jet motion is a specialized form of motion, involving the use of multiple small nozzles to direct a focused stream of oxygen at a surface. This type of motion is commonly used in abrasive processes, such as cutting and carving, where fluids are sprayed onto the s......
Hot metal dephosphorization method
De-phosphorization of Iron by Chemical Method
Phosphorus is often present in iron as an impurity which can be detrimental to its steel making properties. In order to rid the iron of this phosphorus an effective de-phosphorization method is required. One of the chemical methods used is the use of ......
