Self-Baking Carbon Brick
Self-Baking Carbon Brick for Metallurgical Furnaces
Are you looking for reliable carbon lining solutions for your metallurgical furnace operations? Our Self-Baking Carbon Brick offers enterprise-level performance for blast furnaces, submerged arc furnaces, and ferroalloy production facilities. These special refractory materials change during use to make uniform, one-piece linings. They have a set carbon content of at least 85%, an apparent density of at least 1.65 g/cm³, and can handle temperatures up to 1800°C. With more than 20 years of experience and more than 400 sites around the world in a wide range of metallurgical uses, Shaanxi Heyuan offers complete solutions.
What Makes Our Carbon Bricks Different?
Unlike standard carbon blocks that have already been made, our carbon lining solutions change as your furnace starts up. The common "joint penetration" problem that strikes regular refractory systems is solved by this one-of-a-kind feature.
You can place these materials in a "green" state, and the heat from your furnace will finish the carbonization process. As the temperature rises, the binding material moves and cokes, which causes a small amount of expansion that joins the blocks together to make a continuous covering with no joints.
This smooth merging keeps molten metal from getting into the bottom of your furnace. This means that your campaign will last longer and your activities will cost less to maintain.

Key Applications for Your Operations
Blast Furnace Hearth and Bottom
Protecting your blast furnace from liquid iron and slag weathering needs to be strong. For the best heat control, our carbon brick options offer great resistance while still letting heat flow through them.
Submerged Arc Furnaces
In places where ferroalloys are made, these materials can handle temperatures up to 2000°C and harsh reduction conditions. Molten metals that are very fluid can't get into the furnace bottom because of the solid structure.
Calcium Carbide Furnaces
Our Self-Baking Carbon Brick has the electrical properties needed for electrode paths and can also stand up to acidic slag conditions, making it perfect for tasks that need both high electrical conductivity and chemical resistance.

Performance Advantages
Superior Corrosion Resistance
These materials withstand long-term exposure to molten iron and slag without degradation. The dense structure after baking provides excellent barrier properties.
Seamless Monolithic Formation
The self-baking process eliminates joints where molten metal typically penetrates. This prevents the "floating brick" accidents common with conventional linings.
Optimal Heat Management
Good thermal conductivity helps maintain uniform furnace temperatures while reducing thermal stress on your equipment.
Extended Service Life
The combination of chemical resistance and structural integrity significantly improves overall blast furnace campaign life, reducing your operational costs.
Installation and Baking Process
Proper installation requires specific techniques different from standard refractories. You'll need compatible carbonaceous seam paste that matches the brick's volatile content. This ensures uniform expansion and contraction during the baking phase.
The furnace bake-out curve is critical for success. Heating too rapidly causes volatile release problems and potential cracking. Our team provides customized heating curves based on your specific batch characteristics.
During startup, monitor temperature progression carefully. The transformation process typically completes as your furnace reaches normal operating temperatures, creating the protective monolithic structure.
Quality Assurance
We maintain strict quality control throughout production. Key inspection points include:
- Volatile matter analysis using thermogravimetric methods
- Dimensional tolerance verification (±1mm precision)
- Compressive strength testing in both green and simulated baked states
- Comprehensive ash and impurity analysis
Each batch undergoes laboratory simulation testing to verify performance characteristics before delivery.
Delivery and Support
Standard configurations ship within 15-20 days from order confirmation. Custom designs require 30-45 days for manufacturing and quality verification.
Our technical support continues beyond delivery. We provide auxiliary materials supply, maintenance consultation, and troubleshooting assistance throughout your furnace campaign.
