High Temperature Resistant Ceramic Fiber Spoon for Casting: How to Choose Right Sampling Scoop

Sampling is a critical step in the casting process, helping to assess the composition, temperature, and other key parameters of the melted metal. The material of the sampling spoon is crucial in this process, and it is usually mainly used to resist high temperatures and corrosion. The following is the commonly used sampling scoop material in casting:

Refractory Sampling Scoop:


High temperature resistance: Refractory materials such as refractory ceramics, graphite, etc. can maintain stability under high temperature conditions.

Corrosion resistance: Refractories are generally resistant to corrosion and can cope with the corrosive environment of metal melting.

Stable size: Refractory sampling scoop is not easy to change size at high temperatures to ensure the accuracy of sampling.

For high temperature metal liquid sampling in casting.

In casting laboratories, refractory sampling spoons are widely used to assess alloy composition and temperature.

Stainless steel sampling scoop:


High temperature resistance: Stainless steel has good heat resistance in the appropriate temperature range.

Corrosion resistance: stainless steel has good corrosion resistance and is suitable for sampling metal liquids in casting.

High strength: Stainless steel sampling scoop has high mechanical strength and can withstand greater force and weight.


Used to sample high temperature casting metal liquids, such as iron, aluminum, etc.
During the casting process, stainless steel sampling spoons can be used to evaluate the casting quality of metallic liquids.

Ceramic sampling scoop:


High temperature resistance: Ceramic sampling scoop can maintain stability at extremely high temperatures.

Wear resistance: It has certain wear resistance and is suitable for the sampling process of metal liquids.

Chemical inertia: Ceramic sampling spoons usually have good chemical inertia and will not pollute the metal.


Used to sample high temperature metal alloys, such as steel, nickel-based alloys, etc.
In the casting laboratory, ceramic sampling spoons can be used for the study of metal melting reactions.


In casting, the selection of the appropriate sampling spoon material is essential to ensure the accuracy of sampling, maintain the stability of the spoon, and avoid contamination of the metal liquid. Reasonable selection of sampling spoon is helpful to improve the control level of the casting process and product quality.
