Compound Blowing of Steel in the Converter
Introduction
The method of compound blowing of steel ore in the converter is a process for manufacturing refined steel. It is a combination of blowing with compressed air, oxidizing and reduction blowing. This industrial process is used to create converter steel from hot liquid metal, which is then further processed into finished steel products. Here, we will discuss the process and importance of compound blowing in the converter.
Description
The process of compound blowing begins with the steel ore being heated in a furnace until it reaches a liquid state. This liquefied ore is then added to the converter, a large vessel with a pointed bottom. This vessel is then tilted and the hot liquid metal is poured into a ladle. As the converter is tilted, compressed air is blown through a lance into the hot liquid metal. This enhances the oxidation and reduces the amount of carbon in the ore. The addition of the air helps to ignite the carbon in the liquid steel. This allows some of the carbon to be removed, while also increasing the oxygen content of the steel.
After the reduction blowing is complete, the furnace is then tilted to permit oxidizing blowing. During this phase, oxygen is blown into the hot liquid steel once again. This further increases the oxygen content of the steel and helps to further reduce the amount of carbon in the material. The result of both reduction and oxidization blowing is a refined steel product that is ready for further processing into finished steel products.
Importance
The process of compound blowing in the converter is essential for the production of refined steel. The use of compressed air to blow in oxygen helps to reduce the amount of carbon in the steel and also to increase the oxygen content. This creates steel that is much higher quality than when compared to steel created through traditional smelting methods. The process is faster and more efficient, as it does not require the use of additional energy sources, such as coal.
Compound blowing of steel in the converter is important to the production of refined steel, as it increases the quality of the steel produced and reduces the amount of carbon in the material. It also helps to reduce production time and conserve energy. As a result, the process of compound blowing in the converter is an essential part of creating finished steel products that are of a higher quality.
