Technical Definition and Description

The processes take place in a blast furnace, in a massive manufacturing plant. There are three processes involved in making steel. They include Vanadium recovery, The Klockner Oxygen Blown Maxhutte process, and Ladle treatment (Warren, 2001). The process helps in proper management of the different stages of manufacture and the final product. This paper will look at the processes involved in making steel. Step 1- Vanadium Recovery Vanadium is retrieved from the molten iron before it is converted to steel. This is because a large vanadium composition may make the steel extremely hard and there is a high value of the vanadium rich slag that is produced. Oxygen is blown over the surface of a ladle made up of 75 tonnes of molten iron in the vanadium recovery unit. The Oxygen oxidizes vanadium, silicon, manganese and titanium to create a slag that soar on the surface. Also, stirring is done by blowing argon in the molten metal. The slag is removed, chilled and compressed when the constitution of the molten metal has attained the needed vanadium condition. This pretreatment makes the metal to heat, allowing temperature management. In addition, if there is a need, the process can be developed by adding lime to lessen sulfur amounts (Warren, 2001). Step 2- The Klockner Oxygen Blown Maxhutte process This process entails blowing oxygen in the molten metal to oxidize molten impurities. ...

fragments. There is an addition of 70 tonnes of molten iron from the vanadium recovery process in the The Klockner Oxygen Blown Maxhutte. Then, Oxygen is blown in the bottom holes of the furnace, at a speed of almost 1500 liters per second. In addition, Oxygen is passed via a lance at the pinnacle of the furnace at a tempo of almost 2500 liters per liter (Warren, 2001). The Oxygen oxidizes the components except iron to form oxides. This process helps to remove contaminants. This is because the oxides create a slag that appears on the top of the molten metal. The process of slag formation is further enhanced by powdered lime, which is blown in the furnace. In particular, this lessens the quantity of phosphorous and sulfur by merging with their acidic oxides. Iron (III) sulfide is hazardous to steel because of its low melting point. This necessitates the reduction of sulfur amounts before advancement of the process. There is an analysis of the molten iron before being inserted in the furnace and temperature is recorded. This has an impact on the composition and quantity of the scrap being added and helps to establish the duration of the Oxygen blown. The CO: CO2 ratio in the gases contained in the furnace determines the duration of the Oxygen blown. The standard blow time is fifteen minutes (Warren, 2001). Step 3- Ladle treatment Ladle treatment is the final stage of steel making. This stage entails making suitable adjustments carry the constitution of the molten steel from the furnace in procession with the entailed composition. The large part of the alloying components are inserted in the furnace, then the
