Steelmaking is the process by which steel is extracted or made from Iron Ore. It is a very long, age old process which became commercial somewhere around the 19th century. People began to smelt steel on a large scale basis. As such, there began the practice of making steel from iron using two distinct processes. One was the Oxygen steelmaking process, and the other was electric arc steelmaking. Out of these two, the most commonly and highly used method was the Oxygen steelmaking method. This involved starting an exothermic reaction in the vessel being used for smelting steel. This process will separate the impurities, which allowed one to extract pure steel from it, along with a component called Slag.
Maintaining an optimal temperature was very important, since otherwise, the impurities might not get completely separated from steel. It may also get re-oxidized, much before the steel has been completely extracted. What made the people capable of maintaining that thermal temperature was the usage of slag either left over from previous smelting processes, or synthetic slag made from other materials.
Why use a covering compound?
- A covering compound is very important to the process of steelmaking, since they cover the ore being smelted for extracting steel. This in turn, allows the person smelting the steel to regulate or maintain the temperature inside the vessel being used. It is a very important step because maintaining that temperature will result in steel being extracted properly from the ore.
- Slag is a compound that works great in covering the ore. It works like an effective conditioner by insulating the ore and as a result, maintaining the correct temperature required. Natural Slag is great to use, but is very hard to obtain and not cheap. Many modern factories look for alternatives to it to save time and money.
Why Synthetic Slag is highly beneficial as a Covering Compound?
- Synthetic slag is basically an artificial version of natural slag. It is easy to obtain, produce and use because of its nature and abundance. Made from burnt rice husk, synthetic slag works as good as natural slag as a thermal insulating compound.
- While maintaining the temperature, synthetic slag works like a sponge, and absorbs impurities during the smelting process like sulphur, etc. It performs all the tasks natural slag does, and more.
Some benefits of using an Insulating Compound made from Burnt Rice Husk:
- Synthetic slag made from rice husk is cheaper yet a highly useful alternative.
- It minimizes the heat that gets lost during the process by insulating the main compound.
- It is capable of withstanding high temperatures, up to 1600° Celsius while staying durable.
- This Synthetic slag minimizes smoke generated, while keeping the impurities and pollution low. It is eco-friendly and maintains a healthy atmosphere in the factory.
- Finally, synthetic slag ensures the quality of steel that has been smelted from the ore is uniform and superior at all times.
All efforts by the people working to make steel will remain the same, but there is a certain reduction in costs of manufacture and raw products used. As a result, one can see how important synthetic slag, as a covering compound actually is in making the steelmaking process highly efficient.
