Silicon carbide refractory brick is a type of high-quality refractory material that is widely used in various industrial fields. It is mainly made of silicon carbide as the main raw material, mixed with various additives, and sintered at high temperatures. This material has excellent properties such as high temperature resistance, oxidization resistance, high strength and wear-resistance.
The classification of silicon carbide refractory bricks mainly includes four grades: 1700℃, 1800℃, 1900℃, and 2000℃. Each grade of refractory brick has its own unique characteristics and application range. The 1700℃ grade silicon carbide refractory brick is mainly used under 1800℃ high-temperature conditions, while the 2000℃ grade silicon carbide refractory brick is suitable for use in ultra-high temperature environments.
In terms of technical parameters, the refractory brick must have a high bulk density, excellent thermal conductivity, and low thermal expansion coefficient. Additionally, the compressive strength and flexural strength of the brick must also be high enough to meet the application requirements.
The production process of silicon carbide refractory brick is complex, and its production process includes preparation of raw materials, batching, mixing, molding, drying, and firing. During the production process, it is necessary to strictly control the temperature and pressure conditions, as well as the size and uniformity of the brick.
In conclusion, silicon carbide refractory brick is a high-quality refractory material that plays an important role in various industrial fields. It has been widely used in metallurgy, machinery, chemical, building materials and other industries because of its excellent performance. With the development of industry and technology, the application range of silicon carbide refractory bricks will be further expanded.
