In numerous high-temperature industrial fields, magnesia carbon bricks, as a high-performance refractory material, are playing a crucial role. Composed mainly of magnesium oxide and carbon, they exhibit excellent properties through unique formulations and processes, making them an ideal lining choice for many high-temperature equipment.
A Stalwart Guardian in Iron and Steel Smelting
In the iron and steel smelting industry, magnesia carbon bricks are nothing short of a mainstay. During converter smelting, the environment inside the furnace is extremely harsh, with temperatures soaring to 1600 - 1800°C, accompanied by violent temperature fluctuations and strong scouring by molten slag. Thanks to their outstanding thermal shock resistance and slag erosion resistance, magnesium carbon bricks firmly protect the converter lining, especially key parts such as the slag line area and the molten pool area. They significantly extend the service life of the converter lining, greatly reduce the number of furnace repairs, and ensure the continuity and efficiency of production.
In the electric arc furnace smelting process, the erosion of molten steel and slag, as well as the high-temperature radiation from the electric arc, pose a serious threat to the furnace lining. However, magnesium carbon bricks, used in parts such as the furnace wall, furnace bottom, and taphole, effectively resist these damaging factors, ensuring the stable operation of the furnace body and providing a solid guarantee for the production of high-quality steel.
Refining furnaces further purify and refine molten steel. In ladle refining furnaces, parts like the slag line and ladle wall are subjected to the scouring of molten slag caused by strong stirring and high-temperature tests. The wide application of magnesium carbon bricks here not only enables them to withstand harsh working conditions but also ensures the refining effect and the safety of the ladle, helping to produce purer and higher-quality steel. At the same time, in the permanent layer and working layer of the ladle, especially the working layer in direct contact with molten steel and slag, the use of magnesium carbon bricks reduces the loss during ladle turnover, greatly improving the service life and turnover efficiency of the ladle and lowering production costs.
A Reliable Partner in Non-Ferrous Metal Smelting
In the field of non-ferrous metal smelting, magnesium carbon bricks also perform excellently. Take the copper refining furnace as an example. The slag line area of its lining is faced with the dual erosion of copper melt and refining slag, and temperature changes are also frequent. With good erosion resistance and the ability to adapt to temperature changes, magnesium carbon bricks serve stably here, ensuring the smooth progress of the copper refining process.
The high-temperature area of the lining of the ferronickel smelting furnace needs to withstand the strong alkaline erosion of ferronickel slag and high-temperature impact. By virtue of its own characteristics, magnesium carbon bricks can effectively cope with these challenges and provide strong support for the efficient and stable production of ferronickel smelting.
A Capable Assistant for Other High-Temperature Kilns
In large induction melting furnaces, some linings are made of magnesia carbon bricks. The high temperature and scouring of the metal melt have high requirements for the furnace lining, and magnesium carbon bricks can well cope with these working conditions, ensuring the normal operation of the induction furnace and facilitating the efficient development of metal melting work.
When local damage occurs to kilns such as converters and ladles, magnesium carbon bricks can be processed into specific shapes for repair. Their characteristic of quickly restoring the service performance of kilns reduces equipment downtime and improves production efficiency.
Magnesium carbon bricks have shown irreplaceable roles in many fields such as iron and steel smelting, non-ferrous metal smelting, and other high-temperature kilns. Their excellent performance provides a solid guarantee for the efficient and stable production of various industries. If you are facing difficulties in choosing linings for high-temperature equipment in related industries, you may wish to consider magnesium carbon bricks, which will bring unexpected value to your production.
