Structural Characteristics of Shuttle Kilns and Kiln Lining Structure

by

As an advanced type of firing equipment, the shuttle kiln has found widespread application in various sectors: in the machinery industry—specifically in plants producing electrical ceramics and grinding wheels; in the building materials industry—within sanitary ceramics factories; and in other fields such as environmental protection and refractory materials. Characterized by low energy consumption, uniform temperature … Read more

Furnace Chamber Thermal Insulation and Fire Barrier Board — High-Temperature, Energy-Saving Insulation Material

by

Furnace Insulation and Fire-Blocking Boards: Ceramic Fiber Boards. The furnace chamber—also referred to as the furnace core or combustion chamber—requires the use of insulating materials characterized by low thermal conductivity, whether for the chamber itself or for pre-formed furnace cores. As the combustion chamber, the efficiency of fuel combustion directly determines the temperature attained within … Read more

Advantages of Carbon Ramming and Gunning Materials for Blast Furnace Hearths

by

Following the completion of carbon or graphite brick masonry in the blast furnace hearth, carbon-based monolithic materials are also required. The primary monolithic refractory materials utilized in the blast furnace hearth are carbon ramming mixes and carbonaceous injection mixes. Carbon Ramming Mix Carbon ramming mix is ​​categorized into two types: that applied to the furnace … Read more

The Effect of Andalusite on the Properties of Bauxite-Based Low-Creep High-Alumina Bricks

by

To achieve low-carbon, energy-efficient, and high-performance operation—characterized by elevated blast temperatures, extended service life, and large-scale capacity—in blast furnace hot blast stoves, increasingly stringent requirements have been imposed on the refractory materials utilized therein. Bauxite-based homogenized materials, produced through a process of homogenization and sintering, exhibit a uniform microstructure distribution as well as stable chemical … Read more

New Requirements for Silica Bricks in Glass Furnaces Driven by Glass Industry Processes

by

The performance requirements and application demands for refractory materials vary significantly depending on the specific type, size, and structural design of the glass-melting furnaces in use. In the glass industry—particularly for float glass furnaces—the primary categories of shaped refractory materials utilized are fused-cast refractories, silica bricks, and magnesia-based refractories. Silica bricks, a traditional staple among … Read more

Tabular Corundum Mullite Bricks

by

Tabular corundum mullite bricks are made primarily of tabular corundum with mullite as an auxiliary material. They are formed by adding appropriate amounts of high-purity alumina, ultrafine silica powder, and additives, and then subjected to high-pressure pressing using a 300t friction press. The bricks are then fired at high temperatures in an oxidizing atmosphere. Tabular … Read more

Selection Principles and Applications of Lightweight Thermal Insulation Bricks

by

In the energy-saving and consumption-reducing design of industrial kilns, lightweight insulating bricks are a key insulation material. Their material selection and volumetric density configuration directly affect the kiln’s thermal efficiency, structural stability, and operational economy. Rongsheng Refractory Materials Manufacturer recommends the most suitable Lightweight Thermal Insulation Bricks products for the production needs of high-temperature industrial … Read more

Application of Silicon Carbide in Refractory Materials

by

Silicon carbide (SiC), also known as corundum, is rarely found naturally; industrially used silicon carbide is all synthetically produced. Pure silicon carbide is a colorless, transparent crystal. However, industrially produced silicon carbide, due to impurities such as free carbon, iron, and silicon, exhibits various colors, including yellow, black, dark green, and light green, with transparency … Read more

Magnesia Chrome Bricks Combine Corrosion Resistance and Spalling Resistance

by

For ladle refining operations, magnesia-chrome refractories remain the most erosion-resistant refractories. The problem with these refractories is that it’s difficult to reconcile erosion resistance and thermal shock resistance. Specifically, traditional direct-bonded magnesia chrome bricks with high erosion resistance often have low thermal shock resistance; conversely, high thermal shock resistance often results in lower erosion resistance. … Read more

Theoretical Basis of Si-O Refractories – Silica Bricks

by

Refractory bricks made from natural silica-containing rocks, primarily quartz, are called silica refractory bricks. Rongsheng Silica bricks contain at least 93% SiO2 and no more than 1.5% Al2O3, as even a small amount of alumina significantly reduces refractoriness. A key aspect of silica brick manufacturing is the rate of conversion between different silica variants. Get … Read more
