Industry Knowledge of Silicon Carbide Refractory Brick

Silicon carbide refractory bricks, also known as SiC refractory bricks, are widely used in the high-temperature industry due to their excellent high-temperature resistance and thermal conductivity. SiC refractory bricks can withstand temperatures up to 1700°C, making them an ideal choice for applications that require excellent thermal shock resistance and high mechanical strength.

There are several types of silicon carbide refractory bricks available in the market, each of which has unique features and specifications. The main categories of SiC refractory bricks are:
1. Oxide-bonded SiC refractory bricks
2. Nitride-bonded SiC refractory bricks
3. Silicon-infiltrated SiC refractory bricks
4. Recrystallized SiC refractory bricks.

SiC refractory bricks are manufactured using high-quality raw materials under strict quality control. Their technical parameters include:
1. Bulk density: Generally, the density of SiC refractory bricks is between 2.5 and 3.0 g/cm3.
2. Compressive strength: The compressive strength of SiC refractory bricks is higher than other refractory bricks due to their excellent mechanical properties.
3. Thermal conductivity: SiC refractory bricks have high thermal conductivity, which makes them perfect for applications in the metallurgical and chemical industries.
4. Thermal expansion coefficient: The thermal expansion coefficient of SiC refractory bricks is low, which means they can withstand thermal shock without cracking.

The production process of SiC refractory bricks is complex and involves several steps, including mixing, molding, drying, firing, and inspection. The process involves using high-quality raw materials and advanced technology to create refractory bricks with excellent quality and durability. The following are the steps involved during production:
1. Raw materials preparation: The raw materials used in SiC refractory bricks are carefully selected and mixed in the required proportion.
2. Molding: The mixed raw materials are pressed into the desired shape.
3. Drying: The molded bricks are dried in the kiln to remove excess moisture.
4. Firing: The dried bricks are fired in a high-temperature kiln to obtain the required strength and properties.
5. Inspection: The finished SiC refractory bricks are inspected to ensure that they meet the required standards.

In conclusion, SiC refractory bricks are of great significance in the high-temperature industry due to their excellent properties. Their level classification, technical parameters, and production process sets them apart from other refractory bricks. Manufacturers are dedicated to producing SiC refractory bricks with improved performance, durability, and cost-effectiveness to meet the demands of the high-temperature industry.
