Oxygen-enriched smelting
Oxygen enriched smelting is a technology used in the steelmaking process that uses high levels of oxygen injection to improve the level of metallurgical efficiency. The process is a form of indirect smelting, whereby the oxygen injection supplies additional energy, as well as enhancing the oxidati......
Bessemer converter steelmaking
Blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast furnaces operate on the principle of bell-based smelting, whereby a mixture of the ore, the fuel and flux (limestone, dolomite, etc) ar......
Improving the ratio of molten iron in hot charging of electric arc furnace through furnace wall cluster oxygen supply technology
Introduction
For a long time, the electric arc furnace has been widely used in the steelmaking industry to produce molten iron with higher efficiency and lower energy consumption. Although the electric arc furnace is an important equipment for smelting, there are still many shortcomings in the cu......
Top and Bottom Combined Blowing Converter Steelmaking
Blast furnace steelmaking
Blast furnace steelmaking is the process of producing steel from pig iron using a blast furnace. The process originated in China in the 5th century BC, and spread to the rest of the world in the 17th century. It is the most widely used steelmaking process and is used in t......
Oxygen bottom-blown converter steelmaking
Steel Making in an Oxygen Bottom Blown Converter Furnace
Steel making is the process of adding specific elements and mixtures to carbon-rich iron ore to create a steel alloy with a variety of beneficial properties. This process is done in large-scale industrial furnaces, such as oxygen bottom-blo......
Oxygen oblique blowing rotary furnace steelmaking
Introduction
The oxy-fuel bent blow oval reverberatory (or BOF) is a steel melting furnace that uses oxygen-fuel for melting and refining operations. It is most often used in continuous casting of steel, as well as in steel-making processes. This type of furnace has a shank that is curved upwards ......
Measures to Reduce Ladle Temperature Drop
Reducing Steel Shell Temperature Drop
Steel shells are commonly used in environments where heat and motion, and finite element analysis need to be considered. As such, the temperature of the steel shell needs to be monitored and maintained at a specific level for optimal performance. This article......
Technology to Improve the Service Life of Converter Taphole
Methods to Improve Lifetime of Pouring Mouth of Converter
Typically, the service life of pouring mouth of converter largely affects its production efficiency. In the process of using converter, proper maintenance of pouring mouth is very important. In order to ensure the production efficiency and......
Concept of converter volume ratio (V/T) and its influence on blowing process
Vessel-to-tuyere Ratio (V/T) is an important concept in ladle metallurgy and its influence on the blow-ladling process. Vessel-to-tuyere Ratio (V/T) defines the ratio between the internal vessel volume and the amount of air that can be injected from the tuyere, which is usually based on the availa......
