Parameters of silicon carbide briquette refractory for steelmaking
Silicon carbide briquettes are used in steelmaking as a refractory material due to their high thermal conductivity and low sintering energy requirements compared to traditional binders such as silica sand or limestone.
The typical parameters for SiC briquettes in the steel industry include:
* C(1/c): The ratio of the Si content to the total amount of carbon in the briquettes.
* C(2/c): The ratio of the Si content to the total amount of carbon in the briquettes, taking into account the role of carbon in the capping of the particles during sintering.
* SiO2 content: The percentage of SiO2 in the briquettes.
* Si concentration: The concentration of Si in the briquettes, expressed in sieles per kilogram (Si) or grams per liter (g/kg).
* Porosity: The porosity of the briquettes, measured in percent.
* Porosity after firing: The porosity of the briquettes after firing, measured in percent.
It’s important to note that these parameters can vary depending on the specific conditions of the steel production process and the type of briquettes being used. Additionally, the selection of appropriate SiC briquettes will depend on factors such as cost, availability, and the desired properties of the final product.
