Product Description
High Silica Glass Fiber Filter Cloth: The Robust, Woven Solution for Molten Metal Filtration
Discover the durability and simplicity of our thick-weave filter cloth, engineered for demanding applications including steel and iron casting.
In the diverse landscape of foundry filtration, sometimes a straightforward, robust solution is key. Our High Silica Glass Fiber Filter Cloth represents a category of reliable, woven filters designed for efficient gross filtration of molten metals. Particularly in its Thick Type variant, it provides an essential service in conditioning melts for steel, iron, and various non-ferrous alloys by removing slag, dross, and coarse inclusions.
Crafted from high-temperature resistant glass fibers, this woven mesh offers a distinct balance of performance and practicality. It acts as an effective strainer, calming metal flow while capturing larger impurities. For steel foundries requiring a resilient and economical pre-filter or choke, this product is an indispensable tool.
Product Features and Technical Specifications
High-Purity Silica Composition
The core material offers excellent thermal shock resistance and chemical stability against aggressive molten metals.
01
Thick, Durable Weave
The enhanced thickness provides greater handling strength and longevity during the casting process, with a tensile strength exceeding 16kgf/4pcs.
02
Extreme Temperature Capacity
Designed to perform in contact with molten steel at temperatures up to 1600°C, making it suitable for the most challenging pours.
03
Controlled Reaction
Low gas evolution (<60cm³/g) ensures the filter does not become a source of gas-related casting defects.
04
Flexible Format
Supplied as a cloth that can be custom-cut. Standard mesh openings (1.5x1.5, 2.0x2.0, 2.5x2.5) cater to different filtration needs, with full customization available.
05
Understanding Its Role
It is important to note that as a woven cloth with an open area typically around 25%, it primarily provides mechanical screening and flow calming. For deep filtration of microscopic inclusions in critical steel applications, we recommend our Zirconia Ceramic Foam Filters as a complementary or alternative solution. The two technologies can be used in tandem for optimal results.
Practical Application Guide
This filter cloth is user-friendly. Simply cut the desired piece 20-30mm larger than your runner's cross-section using scissors. Position it securely under the gate cup or at the junction of the runner and ingate, ensuring it sits flat on a mating surface. Handle with care during placement to avoid fraying or tearing.
