Blast furnace hearth pouring technology refers to the process of injecting molten iron or other melts into the furnace. It is a key link in the production process of blast furnace, which directly affects the smelting efficiency and product quality of blast furnace. The following will introduce the application of blast furnace hearth pouring technology.

First of all, the influence of pouring technology on blast furnace smelting efficiency. The production efficiency of blast furnace is mainly reflected in the amount of iron and smelting cycle. The application of pouring technology can reduce the splash and splash of molten iron, improve the injection efficiency of molten iron, and increase the amount of iron in the blast furnace. At the same time, the pouring technology can also reduce the injection time and cooling time, shorten the smelting cycle, and improve the production capacity of the blast furnace.

Secondly, the influence of pouring technology on the quality of blast furnace products. The product quality of blast furnace mainly includes tapping temperature, slag composition and molten iron composition. The application of pouring technology can keep the temperature of molten iron stable, prevent the excessive cooling of molten iron in the process of injection, so as to ensure the stability of the temperature of the iron. In addition, the pouring technology can also reduce the gas mixing in the furnace cylinder, reduce the oxidation and reduction of the slag, and maintain the stable composition of the slag. At the same time, the pouring technology can also control the injection speed and angle of the molten iron, avoid the entry of inclusions in the molten iron, and improve the purity and uniformity of the molten iron.

Thirdly, the influence of pouring technology on the convenience and safety of blast furnace operation. The traditional blast furnace pouring method is manual operation, manual operation is not only cumbersome, but also has security risks. The application of pouring technology can realize automatic control, reduce manual operation, and improve the convenience and safety of operation. Pouring technology can monitor and adjust parameters such as temperature, pressure and flow in the pouring process through sensors and automatic control systems, grasp the state of molten iron in real time, predict the temperature and flow of iron, so as to ensure the safe operation of the blast furnace.

In short, the application of blast furnace hearth pouring technology has an important influence on the smelting efficiency, product quality and operation safety of blast furnace. Through the rational selection and application of pouring technology, the blast furnace can improve the amount of iron, reduce product quality fluctuations and operational risks, so as to enhance the overall competitiveness of the blast furnace.
