Application fields of silica bricks

Silica-molybdenum brick is a new type of high-efficiency refractory material with high refractoriness, good thermal shock resistance and chemical corrosion resistance. It is widely used in many high-temperature industrial fields. The following are the main application areas and specific uses of silica-molybdenum bricks:

Steel Industry

Silicon-molybdenum bricks are widely used in blast furnace linings, ladles, tapholes, hot blast furnaces, furnace roofs, furnace bodies and other parts in the steel industry. Due to their high strength and compressive strength, silicon-molybdenum bricks can maintain structural stability at high temperatures and resist the erosion of acidic or alkaline slag, thereby extending the service life of blast furnaces and other equipment.

Cement Industry

In the cement industry, silica-molybdenum bricks are mainly used in the secondary firing zone, transition zone, cooling zone and other parts of cement rotary kilns. Silica-molybdenum bricks can withstand high temperatures and the friction of materials in the kiln, and have good resistance to chemical erosion, especially excellent alkali erosion resistance. In addition, silica-molybdenum bricks can also resist temperature fluctuations and mechanical stress, reduce cracks or spalling caused by thermal stress, and thus improve the working efficiency and stability of cement rotary kilns.

Glass Industry

Silica-molybdenum bricks also play an important role in the glass industry. They are often used in the partition walls of the kiln regenerator and the inner lining of the furnace to resist the chemical erosion of molten glass and high-temperature gas. Silica-molybdenum bricks have high chemical stability, which can prevent the contamination of molten glass. At the same time, they are not easy to deform and peel off at high temperatures, which prolongs the service life of the kiln.

Ceramic Industry

In the ceramic industry, silica-molybdenum bricks are mainly used in the inner lining of ceramic tunnel kilns and the insulation of combustion chambers, as well as in high-temperature working environments such as roller kilns. Silica-molybdenum bricks have excellent thermal shock stability, can prevent cracking or falling off, and have good high-temperature tolerance, which is suitable for high-temperature firing environments of ceramics.

Power Industry

Silicon-molybdenum bricks are also widely used in the power industry, especially in the linings, chimneys and heat exchangers of power plants and boilers. Silica-molybdenum bricks can resist the erosion of high-temperature flue gas and ash, have good wear resistance and strong thermal shock resistance, thus ensuring the normal operation and safety of power equipment.

Chemical Industry

In the chemical industry, silica-molybdenum bricks are suitable for high-temperature equipment in chemical reaction environments, such as gasifiers, incinerators, etc., due to their good high-temperature tolerance and corrosion resistance. Silica-molybdenum bricks are highly resistant to acid, alkali and oxide corrosion, and are suitable for high-temperature conditions in harsh chemical environments.

Other fields

In addition, silica-mullite bricks are also used in lime rotary kiln lining, particle steel rotary kiln, magnesite incinerator, sintered mullite rotary kiln and other fields, and also show excellent refractory performance, thermal shock resistance and chemical stability.

In summary, silica-molybdenum bricks play an important role in many high-temperature industrial fields with their unique performance advantages. However, the specific working environment and requirements of different fields are different, so when choosing silica-molybdenum bricks, it is necessary to make comprehensive considerations based on the actual situation. At the same time, correct installation and maintenance are also crucial to ensure the performance of silica-molybdenum bricks and extend their service life.
