Limestone is added as a raw material to the furnace primarily to act as a flux in the iron and steel-making process. When heated, it decomposes to produce lime, which helps to remove impurities such as silica and alumina by forming a slag that can be easily separated from the molten metal. This not only enhances the quality of the final product but also protects the furnace lining from damage. Additionally, the use of limestone can help improve the efficiency of the smelting process.
What else can I help you with?
Colourless or brownish material used in glassmaking?
Glass batch or cullet is the colourless or brownish material used in glassmaking to produce glass. It is a mixture of raw materials such as silica sand, soda ash, limestone, and recycled glass that is melted in a furnace to create glass products.
How burden calculated in blast furnace?
The burden in a blast furnace refers to the materials added to the furnace for the iron-making process. The burden typically includes iron ore, coke, and limestone. The burden calculation takes into account the proper proportions of these materials to achieve efficient iron production and maintain the desired chemical and physical balance within the furnace. Various factors, such as the quality of the materials and the operating conditions, influence the burden calculation in a blast furnace.
How are the raw materials in glass acquired?
Glass is a compound of Silicon, Silicon is widely collected from Sand and rock
What equipment is used to refine iron ore?
The first thing required is a blast furnace, which is filled with iron ore, coke, and crushed limestone. Then it is fired and a strong air blast is blown upwards through the furnace.
What is most abundant chemical sedimentary rock?
Limestone is the most abundant chemical sedimentary rock. It is formed mainly from the accumulation of the remains of marine organisms such as coral and shellfish. Limestone is used extensively in construction and as a raw material in various industries.
What raw material are put into a blast furnace?
The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom. The raw materials require 6 to 8 hours to descend to the bottom of the furnace where they become the final product of liquid slag and liquid iron.
The blast furnace in a steel mill represents?
raw material
What raw material is used to make glass?
Limestone Sand
What are the 3 raw materials used in the blast furnace?
The three raw materials used in a blast furnace are iron ore, coke, and limestone. Iron ore is the primary source of iron, coke is used as a fuel and reducing agent, and limestone helps to remove impurities from the iron ore.
What is the function of air in the blast furnace?
to burn coke that will burn the raw material
Which one of the following is the predominant raw material used in the manufacture of cement?
Limestone
What are the raw materials fed into the blast furnace?
The raw materials fed into the blast furnace typically include iron ore, coke (a form of carbon), and limestone. Iron ore is the primary source of iron, coke acts as a fuel and reducing agent, while limestone helps remove impurities during the smelting process.
Colourless or brownish material used in glassmaking?
Glass batch or cullet is the colourless or brownish material used in glassmaking to produce glass. It is a mixture of raw materials such as silica sand, soda ash, limestone, and recycled glass that is melted in a furnace to create glass products.
What raw material use in blast furnace?
There are FOUR (4) raw materials used in the Blast Furnace. They are ;- Iron Ore (iron Oxide ' Fe2O3 Coke (Impure Carbon (C). Limestone ( impure Calcium Carbonate CaCO3). These three are intimately mixed to produce a 'honeycomb' of the mixture named ' Sinter'.. Because of this 'homeycomb' it allows the hot air to enter and intimately mix with the sinter and react. AND Don't FORGET OXYGEN ( The hot blast of air).
What the raw material that is added to a system for processing is known as?
Well if the processing is milling flour, then the raw material is called "grist".
