Refractory Magnesia Carbon Bricks

Application fields of magnesia carbon bricks

In the metallurgical industry, magnesia-carbon bricks are mainly used for lining and covering high-temperature equipment such as converters, electric furnaces, and ladles. They can effectively resist corrosion and thermal shock under extreme conditions such as high temperature and high pressure.

In the chemical industry, magnesia carbon bricks are often used as hot surface materials in equipment such as refineries and fertilizer plants. They can withstand corrosive gases and high temperatures to ensure the stable operation of equipment.

In the field of machinery manufacturing, magnesia carbon bricks can be used to manufacture high-performance electrodes, furnace materials in the semiconductor industry, high boron alloys, etc.

Performance characteristics of magnesia carbon bricks

1. Excellent high temperature resistance: Magnesia carbon bricks have excellent high temperature performance and can be used for a long time above 1200°C.

2. Corrosion resistance: Because magnesia carbon bricks have excellent corrosion resistance, they can be used in highly corrosive environments such as acids and alkalis.

3. Good thermal shock resistance: Magnesia carbon bricks have very good thermal shock resistance at high temperatures and can withstand large temperature gradient changes without cracking.

4. Good thermal conductivity: Magnesia carbon bricks have good thermal conductivity and can evenly distribute and transfer heat, which is beneficial to improving production efficiency.

Manufacturing process and advantages of magnesia carbon bricks

The manufacturing process of magnesia carbon bricks mainly includes mixing, pressing, baking, graphitization and heat treatment. Compared with traditional refractory materials, magnesia carbon bricks have the following advantages:

1. Excellent electrical conductivity: As a conductive refractory material, magnesia carbon brick has excellent electrical conductivity and can be used as an electrode material.

2. High corrosion resistance: Magnesia carbon bricks still have good corrosion resistance in strong corrosive environments such as acid and alkali.

3. Strong oxidation resistance: Magnesia carbon bricks have very strong oxidation resistance, can resist oxidation in the air, and have very good long-term durability.

4. Good environmental protection: The production process of magnesia carbon bricks has no pollution, no waste water, and no waste gas emissions. It is an environmentally friendly refractory material.

In summary, magnesia-carbon bricks, as a high-performance, high-temperature, high-pressure refractory material, have been widely used in metallurgy, chemical industry, machinery manufacturing and other fields, and also show many advantages in terms of manufacturing process and performance characteristics.
