The energy-saving function of plug brick in iron and steel industry is mainly reflected in the following aspects:

I. Reduce the heat loss of molten steel

Plug brick can effectively reduce the heat loss of molten steel during pouring by accurately controlling the flow of molten steel. High-quality plug bricks have good sealing performance, which can ensure that molten steel does not leak during flowing, thus reducing heat loss.

II. Improve service life and reduce replacement frequency.

Modern plug bricks have significantly improved their service life by optimizing materials and production technology. For example, the strength and wear resistance of plug bricks made of composite materials are greatly improved, and the service life can reach 15-20 hours. This reduces the energy consumption and production interruption caused by frequent replacement of plug bricks.

III. Optimize production process and reduce energy consumption

The production technology of plug bricks is also constantly improved to achieve energy saving and emission reduction. For example, the plug brick produced by non-firing (non-firing) process avoids the high-temperature firing process and significantly reduces energy consumption. This production process not only reduces the use of fuel, but also reduces the carbon dioxide emissions caused by the firing process.

IV. Reduce the waste of molten steel

The efficient sealing performance of plug bricks can ensure that molten steel does not leak during pouring, thus reducing the waste of molten steel. This not only reduces the production cost, but also reduces the energy consumed by treating waste water.

V. Synergistic energy saving with continuous casting process

In the continuous casting process, the performance of plug bricks directly affects the efficiency and energy consumption of the continuous casting process. High quality plug bricks can ensure the stable operation of continuous casting process and reduce the production interruption caused by the damage or replacement of plug bricks. In addition, by optimizing the material and design of plug bricks, the energy consumption in continuous casting can be further reduced.

VI. Reducing nitrogen consumption

In the process of continuous casting, the sealing performance of plug bricks can reduce the use of nitrogen. For example, nitrogen waste caused by leakage can be reduced by optimizing the design and materials of plug bricks.

To sum up, the energy-saving function of plug brick in iron and steel industry is mainly realized by reducing heat loss, prolonging service life, optimizing production process, reducing molten steel waste and cooperating with continuous casting process. These measures not only reduce energy consumption, but also improve production efficiency and product quality.
