What Are the Advantages of Silicon Carbide Rollers?
- Excellent high-temperature flexural strength;
- No bending or breaking after long-term high-temperature use;
- Good oxidation resistance;
- Excellent high-temperature creep resistance;
- Superior to alumina rollers in terms of thermal shock stability and high-temperature load resistance;
- Good wear resistance;
- Extremely long service life.
Typical Applications of Silicon Carbide Roller
Carborundum rollers are a type of silicon carbide kiln shelves for sale. They support and transport ceramic blanks and glass products in roller-firing kilns and roller-drying kilns. For example, they are mainly used in roller kilns for daily-use porcelain, sanitary porcelain, architectural porcelain and magnetic materials. Therefore, silicon carbide is the core component of roller kilns.
In addition, SISIC silicon carbide roller rods are also widely used in tunnel kilns, natural gas kilns, electric furnace wire kilns, silicon carbon rod kilns and other kilns.

Use and Replacement of SISIC Rollers
There are some small details to pay attention to when using and replacing silicon carbide rollers. Before use, the quality of the silicon carbide rollers must be checked. The quality of the silicon carbide rollers can be judged based on the deviation of the size, the straight line standard, and whether the state changes under rapid cooling and heating.
When replacing the silicon carbide rollers, pay attention to the temperature and take measures to prevent cold air from entering during the operation. When replacing the silicon carbide rollers, record the time, quantity, number and other information for the next replacement. See more on Pinterest.
