Common Issues During the Installation of Magnesia-based Dry Vibratable Mixes for Tundishes

The working lining of the tundish comes into direct contact with molten steel; therefore, it is required to reduce inclusions in the melt, enhance steel purity, and exhibit strong resistance to erosion by molten steel and slag. Additionally, it should facilitate extended casting times for thin-slab continuous casting and allow for easy dismantling after use … Read more

Which Refractory Castable is Selected for Kiln Linings Operating at 1300°C?

Performance Characteristics, Classification, and Applications of Low-Cement Refractory Castables

Low-cement and ultra-low-cement refractory castables are castable refractory materials containing less than 8% calcium aluminate cement. According to ASTM standards, low-cement castables require a CaO content of less than 2.5% (typically 1.0%–2.5%), while those with a CaO content of less than 1% are classified as ultra-low-cement castables. Unlike conventional refractory castables, these materials feature a … Read more

Rongsheng Self-Flowing Castable Self-flowing castables achieve their flow characteristics—without the need for vibration—by utilizing … Read more

Semi-Lightweight Mullite Castable for Tundish Lining

Heat loss from molten steel in the tundish occurs primarily in three forms: heat dissipation from the upper surface, heat storage within the lining, and heat conduction through the lining to the outer shell. By optimizing the performance specifications of the tundish lining castable and developing a long-life, semi-lightweight mullite castable, the goal of safe, … Read more

Key Points for Selecting the Bulk Density of Lightweight Refractory Castables

Insulating refractory castables—also known as lightweight refractory castables, thermal-insulating refractory castables, or simply insulating castables—are hydraulic, unshaped insulating materials. They are formulated by dry-mixing lightweight insulating aggregates as the primary component with refractory powders, binders, and additives in optimal proportions. Characterized by low bulk density, low thermal conductivity, and superior thermal insulation performance, they are … Read more

What Role Does Raw-Material Composition Play in the Performance of Silica Refractory Ramming Mass?

Silica ramming mass is a dry ramming material composed of high-purity microcrystalline quartz sand and powder, blended with high-temperature sintering agents and mineralizers. Thanks to a proprietary particle size distribution design, a dense monolithic furnace lining can be achieved using various ramming techniques. It is primarily used for the working lining of coreless induction furnaces … Read more
