The purpose and means of out-of-furnace refining
Introduction
External refining is a metallurgical process used to produce high-quality steel ingots and billets by removing impurities from the molten steel. This is done by controlling the chemical compositions of the steel, by using a process of decarburization and oxidation through the additi......

oxidation method
The electrochemical oxidation method is a common industrial wastewater treatment method for the advanced treatment of organic pollutants. It is an effective way to degrade organic pollutants and reduce organic pollutants in wastewater. In this method, the organic pollutants in the wastewater are t......
Classification and characteristics of common industrial steelmaking methods
Steel Production
Steel production is a complex process that involves multiple steps, including the use of specialized equipment and materials to produce a final product. In general, steel production begins with the smelting process, in which iron ore is combined with coke (a form of carbon) and h......
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 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......
Blast Furnace Smelting in Baiyun Obo Mine
The Baiyun-ebo Mining District is situated in the mountains of western Gansu Province. The area is renowned for its copper molybdenum ores, which have been mined by locals for centuries. Recently, a large open-cut copper and molybdenum ore mine was established in the area. The ore is processed wit......
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 ......
Electrical conductors ultrasonically welded to thermally sprayed surface layers
Ultrasonic hot dip coating and surface ultrasonic welding on conductive body
Ultrasonic welding is a widely used method for joining materials in the manufacture of components. This welding type has the advantage of not requiring any external heat sources, as the heat is generated by vibrations wi......
Coating of color-coated steel sheets
Coating a Galvanized Steel Panel
Galvanized steel panels are commonly used in construction, creating a reliable and long-lasting surface that is not prone to corrosion. The process of coating a galvanized steel panel is a time consuming process that requires special attention and knowledge. Ensur......
Immersion nozzle and its function
Immerse Type Water Outlets and Their Function
Water outlets, sometimes referred to as fountains, have been around for centuries. From the first time man discovered running water, he is thought to have used it for drinking and bathing. In recent years, the design and implementation of immerse type......
