Product features

Strong high temperature resistance: the maximum operating temperature can reach 1760℃, it can maintain stable physical and chemical properties in high temperature environments, and is suitable for various high temperature casting scenarios.

High filtration efficiency: It can efficiently filter metal particle impurities such as slag and refractory fragments down to the micron level. It can effectively remove impurities that ultimately lead to product quality defects and reduce tool wear during casting machining.

Improve the quality of castings: Make the molten metal filling smoothly and the casting structure uniform, thereby improving the surface hardness, tensile strength, fatigue resistance and other mechanical properties of the castings, and reducing the scrap rate of castings.

Good rectification effect: Its three-dimensional mesh structure has a good rectification effect on metal turbulence, and has a good control effect on non-metallic inclusions and secondary oxidation caused by turbulent flow erosion of the mold cavity.

Simplified pouring system: It can simplify the traditional pouring system and improve the cavity utilization. At the same time, the casting surface is clean, the machining allowance is reduced, the cleaning time is shortened, and the delivery efficiency is improved.

High strength and stability: high strength, good thermal stability, large surface area, and high dimensional accuracy. It can not only effectively filter out macroscopic impurities in molten steel, but also use the surface to adsorb microscopic inclusions.

Stable chemical properties: Normally non-toxic and harmless, it does not react with molten metal during pouring, does not produce smoke, and does not produce harmful smoke during falling sand and sand regeneration.

Product use

The core function of zirconia filters is to purify high-temperature metal melts, so they are widely used in fields that require high metal purity and casting quality:

Cast steel and cast iron industry

It is used in the production of various steel castings (such as gears, valve bodies) and large iron castings (such as machine tool beds) to filter impurities in molten steel and molten iron, reduce defects such as pores and inclusions in castings, and improve product qualification rates.

Aerospace and high-end equipment fields

It is suitable for the casting of high-end castings such as aerospace engine blades and spacecraft structural parts. It can filter the melt of high-temperature master alloys (such as titanium alloys and nickel-based high-temperature alloys) to ensure material purity and mechanical properties and meet the use requirements under extreme working conditions.

Non-ferrous metal and alloy manufacturing

In the continuous casting and low-pressure casting of non-ferrous metals such as copper alloys, magnesium alloys, and aluminum alloys, it filters oxide slag and non-metallic inclusions in the melt, improves the density and surface quality of alloy materials, and is used in electronic devices, precision parts and other fields.

Special materials production

It is used in the melting and molding process of special materials such as magnetic materials (such as neodymium iron boron) and superconducting materials. It uses high-precision filtration to avoid the impact of impurities on material properties and ensure key indicators such as magnetic properties and conductive properties.

Large and complex castings casting

For large-size, complex-structured castings (such as wind turbine hubs and ship parts), the rectification and purification effects of zirconia filters can improve the filling effect of molten metal, reduce casting defects, and improve the overall quality of castings.

In short, with its characteristics of high temperature resistance, high precision, and high stability, zirconia filters have become a key material for improving product quality in the high-end metal casting field, and are widely used in aerospace, machinery manufacturing, nonferrous metals, special materials and other industries.
