Movement of Blast Furnace Stock.
Blast furnance Stock is the main component of the ironmaking process. Its the iron ore, coke and fluxes that are fed into the blast furnace to create pig iron. This process occurs in a large blast furnace vessel, which is a tall cylindrical structure surrounded by refractory lining. Within the vessel, the materials are alternately charged, melted and processed.
In order to make it purposeful, the movement of the blast furnace stock needs to be controlled precisely. The charging of the blast furnace stock consists of three major steps: the loading of raw materials, the charging of raw materials and pushing agents, and finally the blowing of air into the furnace.
For loading of raw materials into the furnace, it is important to make sure that the correct type and quantity of raw materials are loaded. The raw materials for ironmaking include iron ore, coke and fluxes. The type and quantity of materials being loaded need to be adjusted according to the desired quality of the end product. There are several ways of ensuring a proper loading, from manual hand loading to automated loading systems. The choice of loading system depends on the size and complexity of the blast furnace.
Once the raw materials are loaded, pushing agents need to be added to ensure good circulation of the materials inside the furnace. This helps improve the efficiency of the melting and processing because it ensures that the molten materials flow properly and evenly around the vessel. Common pushing agents used in blast furnaces are coke breeze and refractory alumina.
Finally, air needs to be blown into the furnace vessel to allow the reactant gases to react with the molten mass and achieve the desired product. Air needs to be blown into the furnace at a precise rate to provide the right amount of oxygen to the reaction. The reactions between the reactants create gaseous products that need to be collected and processed outside the furnace.
All of the charging and pushing steps of the blast furnace stock need to be closely monitored in order to get the desired end product. The temperature of the molten mass also needs to be closely monitored and adjusted accordingly. If the molten mass is too cold, for example, the desired reactions will not be achieved. Additionally, changing the furnace atmosphere can affect the quality and quantity of the end product.
The movement of the blast furnace stock is a very delicate and complicated process, but an extremely important one that has been used in the ironmaking industry for centuries. It takes precise knowledge and experience to optimize the movement of the blast furnace stock, but the end result is a high-quality product that is used in many industries around the world.
