The composite blowing converter is an equipment used to smelt and refine steel, also known as a top-blowing converter. It is a combination of a basic oxygen converter and a secondary refining or thermite refining converter. It is a type of converter commonly used in steel plants.
The composite blowing converter plays an important role in the steelmaking process. This process is known as the Bohr effect, which is the process of converting the oxygen content of iron ore into the actual component of steel, making the steel more malleable and durable. The process requires high temperatures and precise control of the converters parameters including temperature and gas pressure. The converter has to be able to mix the correct amount of oxygen into the steel, in order to make it stronger.
The operation of the converter is very simple and it consists of an air receiver, a blast burner and a converter vessel. The air receiver stores oxygen for the blast burner. The blast burner is then ignited to start the reaction and to create the high temperature required for the steel production process. The converter vessel is then filled with the raw materials, such as iron ore, and heated up to the required temperature. This can take up to 30 minutes. The reaction of the oxygen and the material produces by-products, such as slag, very hot molten iron and other gases, which are safely removed from the reactor.
Then, the main operation begins inside the converter, which is the oxidation and desulphurization process, also known as the purification. During this process, the iron reacts with the oxygen to increase the carbon content in the material, which makes it more malleable. The purification process also eliminates the sulfur content, which makes the steel ductile and durable.
After this operation, the desired product comes out from the converter and is cooled and shaped into different sizes, depending on the purpose. The product from the composite blowing converter is the best quality steel, which contains the lowest amount of sulfur, phosphorus and other impurities.
The converters parameters are very important and vary depending on the type of steel that needs to be produced. The parameters have to be periodically checked to ensure accuracy and reliability. Considerations include the rate of air flow, the different temperatures inside the converter, the oxygen flow rate and the amount of time the reaction needs to take place.
The composite blowing converters are an essential part of the steel production process. They help to produce high quality steel, and they ensure the highest temperature and most accurate oxygen content to create the desired product. As such, it is important to ensure that the converter is operating correctly and safely, and that it is periodically inspected for any problems.
