Product Description

Product Description

Ceramic filter products are ceramic articles produced via a special process, featuring honeycomb or foam-like porous structures. They boast numerous advantages such as stable chemical properties, high strength, high-temperature resistance, good thermal shock resistance, and a large specific surface area. Thus, they are widely applied in metallurgy, foundry, environmental protection, and other fields.

I. Features:

1. Reduce the rejection rate of castings and minimize pore defects.

2. Exhibit extremely remarkable filtering effects.

3. Enhance the mechanical properties of castings.

4. Simplify the gating system and improve the utilization rate of templates.

5. Ensure a relatively large and stable metal flow rate.

6. Possess high working strength at high temperatures, as well as thermal shock resistance and resistance to molten metal impact.

7. Reduce processing time and tool damage.

8. Achieve extremely high dimensional accuracy.

 Selection of Filter Size and Mesh:

1. Consider the cleanliness of molten metal and the pouring temperature.

2. Take into account the pouring head of molten iron, and calculate the pouring area to meet the requirements of pouring time.

3. Try to use a bottom-pouring gating system to avoid air entrainment.

4. Calculate and select the filter plate area based on filtering capacity and pouring time requirements.

5. Filtering capacity of silicon carbide foam ceramic plates (Kg/cm²): Gray iron: 4.0; Ductile iron: 2.0; Alloy cast iron: 1.0–2.0.

6. Generally, 20ppi is used for gray iron, and 10ppi for ductile iron. 15ppi or 25ppi can also be selected. The mesh selection is related to various factors of actual pouring.
