What is the purpose of basic oxygen furnace?
A basic oxygen furnace (BOF) is a vessel used to convert hot metal into steel. The process is known as the basic oxygen furnace process, basic oxygen steelmaking, or the oxygen converter process. During the process, oxygen is blown into a BOF converter containing liquid hot metal containing high carbon content.
What is the function of a basic oxygen furnace and an electric arc furnace in steel making?
Basic Oxygen Furnace (BOF) Steelmaking – This process converts pig iron from the blast furnace into liquid steel by blowing oxygen into the furnace to remove carbon as carbon monoxide gas. Electric Arc Furnace (EAF) Steelmaking.
What are the advantages of oxygen over air in steel making process?
Commercial advantages include high production rates, less labour, and steel with a low nitrogen content. Development of the BOP was initiated in Switzerland by Robert Durrer in the late 1940s.
Why Oxygen is used in steel plant?
The lance “blows” 99% pure oxygen over the hot metal, igniting the carbon dissolved in the steel, to form carbon monoxide and carbon dioxide, causing the temperature to rise to about 1700 °C. This melts the scrap, lowers the carbon content of the molten iron and helps remove unwanted chemical elements.
Why oxygen is manufactured in steel plants?
Oxygen pretreatment in the ladle is used to reduce the metalloid content of open hearth furnace charges. In solid fuel combustion, producer gas can be upgraded to increase melting rates in open hearth furnaces. Oxygen is used to increase ferromanganese production and to decrease the specific fuel consumption.
Do steel plants use oxygen?
In view of the high demand for oxygen in the country, steel plant requires gaseous oxygen, primarily for steel making and for oxygen enrichment in Blast Furnaces, apart from some general purposes like lancing and gas cutting.
Do steel plants make oxygen?
Steel plants enhanced manufacturing and supplies of medical oxygen by reducing the production of nitrogen and argon gases.
Why is scrap added in BOF steelmaking?
Thermal balance of basic oxygen furnace (BOF) steelmaking is controlled primarily by the scrap added as coolant. These coolants have varying cooling effects and significantly influence the blowing parameters and turn-down performance.
How much does an oxygen plant cost?
A plant that can supply 24 cylinders worth of gas per day costs about Rs 33 lakh to set up and can be completed in a couple of weeks. A 240-bed hospital would require about 550 LPM oxygen. A hospital of that size, say with 40 ICU beds, ordinarily uses oxygen worth about Rs 5 lakh per month.
How oxygen is produced in oxygen plant?
Oxygen can be produced from a number of materials, using several different methods. The most common natural method is photo-synthesis, in which plants use sunlight convert carbon dioxide in the air into oxygen. This offsets the respiration process, in which animals convert oxygen in the air back into carbon dioxide.
Which plants are best for oxygen?
Top 9 Plants that Provide Oxygen
- Aloe Vera Plant.
- Pothos Plant.
- Spider Plant.
- Areca Palm.
- Snake Plant.
- Tulsi.
- Bamboo Plant.
- Gerbera Daisy. The colourful flowering plant not only makes the house look beautiful but is an excellent indoor plant for oxygen.
Which tree gives us more oxygen?
Peepal Tree
