Kerui Refractory materials play an important role in the steel industry. Kerui steel furnace refractory can withstand high temperatures and harsh environments, which can ensure the life service and stability of steel making equipment. The success of steel production depends on the excellent performance of refractory materials, as they can prevent heat loss and protect the structure of the furnace. The following is more about refractory materials used in the steel industry.
The Importance of Refractory in Steel Industry
- Lower Production Cost: In steel manufacturing, common materials deteriorate rapidly, which can lead to frequent maintenance, downtime and significant production losses. However, refractories can withstand these harsh operating conditions. This ensures the stability of high-temperature equipment in the steel industry.
- Increase Productivity: Kerui Refractory materials improve the production efficiency of the steel industry by providing excellent high-temperature resistance, insulation, and chemical stability. These properties can extend the service life of the furnaces, improve equipment productivity and energy utilization.
- Improve Safety Performance: The steel furnace refractory helps maintain a safe working environment for personnel in the steel industry, as it acts as an insulator to minimize heat transfer to the outside surface of the furnace. This helps to prevent overheating, reduce accident risk, and improve overall workplace safety.[/one_third_last]
Different Types of Steel Furnace Refractory Materials
There are several types of refractory in steel industry, each specifically designed to withstand the harsh conditions of the high-temp steel making process. Meanwhile, these materials are carefully selected based on their properties, chemical composition and application requirements. Some common types of steel furnace refractories include:
Magnesium Refractory in Steel Industry
Fused magnesia is raw magnesia sand melted at high-temp and then cooled to form dense, high-purity magnesia sand crystals. it has excellent resistance to alkaline slag and high-temp environmental corrosion.
These refractories combine magnesium and calcium aluminate cement to form a material with improved thermal shock resistance and mechanical strength. Meanwhile, they often have wide usage in ladle applications.
Magnesia carbon bricks are a refractory material formed by mixing magnesium and carbon to enhance its corrosion and thermal shock resistance. So they are suitable for use in the steel industry for lining electric furnaces and ladles.
Magnesia chrome bricks are mixtures containing magnesium oxide and chromium oxide that provide excellent corrosion resistance to acidic slags. So they are appropriate in steel-making applications where acidic conditions are prevalent.
Aluminum Refractory in Steel Industry
These refractories contain a high percentage of alumina, usually over 48%, and have excellent high temperature resistance and mechanical strength. Besides, high alumina bricks are used in a variety of steel making applications.
Clay fire bricks are bricks that contain aluminum oxide as well as silica and other clay minerals. They are typically suitable for use in steel making equipment with less severe temperatures, such as hot blast furnaces and reheat furnaces.
These bricks are refractory in steel industry that contain alumina and chromium oxide. They provide excellent resistance to corrosive acidic slags. They have a wide range of applications such as the side walls and bottom of ladles.
Silica Refractory in Steel Industry
This bricks consist of high-purity silica with excellent thermal stability and resistance to acidic environments. Therefore, they are typically suitable for relatively low-temperature applications.
Silica ramming mass is a loose refractory material composed of high-purity silica grains and a bonding agent. It is used as a refractory lining in induction furnaces for steel melting.
Silica mortar is a kind of refractory binder suitable for bond silica bricks or other siliceous refractory materials. It provides excellent adhesion and heat resistance to ensure the integrity of the lining.
Silica insulation bricks have low density and low thermal conductivity. They are used in areas where thermal insulation is required, such as ladle backup linings or other areas of low thermal stress.
Properties of Refractories in Steel Making
Refractories in steel making possess specific properties that are crucial for their successful application in demanding and high-temp environments. At the same time, these properties ensure the optimal performance and longevity of refractory linings, which directly impact the efficiency and quality of the steel making process.
