回答：Ladle refining furnace that is equipped with inspired oxygen, also referred to as ‘Top Blowing Converter’, is widely used for secondary metallurgy, which is a process of refining and alloying steel. This furnace can be used to process a large variety of different steel alloys, from light carbon steel to special alloy steel.
The Top Blowing Converter is a large cylindrical vessel lined with refractory bricks, and it may be equipped with one or more tuyeres. During operation, the vessel is filled with scrap steel (or liquid steel in some cases) and oxygen is blown in through the tuyeres or a special nozzle. Through a reaction with carbon in steel, oxygen forms a large amount of carbon monoxide. The combination of these gasses results in an oxidation process and the steel is being refined.
The Top Blowing Converter also allows for a variety of other treatments and alloys in the steel. Depending on what is desired, ferroalloys such as ferromanganese and ferrosilicon can be added, as well as other alloys and carbon to acquire different physical properties. This can result in a variation in strength, ductility and other parameters of the steel.
The use of the Top Blowing Converter is not limited to just steelmaking. It is also used to decarburize molten iron and for calcination processes, as well as for silicothermic processes and for glassmaking.
The Ladle refining furnace is a major innovation in steelmaking. Its ability to refine and alloy a large variety of steel alloys in a relatively short period of time allows factories to save time, money and resources. By carefully adjusting the furnace temperature, duration of burning and the rate of oxygen flow, steelmakers can achieve a variety of different properties in the steel they are producing. This is one of the most important pieces of equipment in the steelmaking industry and its importance will only increase in the future.
