The comparison of fiber paper and coating technology in the properties of caster tip/casting tips and nozzle

Dec. 24, 2024

In the casting industry, fiber paper and coating are utilized to enhance the caster tip/casting tip and nozzle performance and prolong its service life. Here is a comparison of their respective performance capabilities:

1. Stick Ceramic Fiber Paper

a. Strength and Support: Fiber paper, particularly that composed of natural or synthetic fibers, exhibits superior tensile strength. When adhered to the caster tip/casting tip and nozzle, it offers enhanced structural support, thereby preserving the shape and stability of the caster tip and nozzle.

b. Thermal Insulation: Fiber paper possesses favorable thermal insulation properties, which can prevent excessive heat loss during the casting process and facilitate the solidification and shaping of the alloy.
c. Application Flexibility: Fiber paper can be tailored and affixed to the caster tip and nozzle in its shape and size, rendering it highly adaptable.
d. The utilized fiber paper must be disposed of appropriately to prevent adverse environmental impacts.

2. Coating

a. Surface Quality: The coating is capable of filling the minute pores on the surface of the casting tip and nozzle, reducing the surface roughness of the casting, avoiding defects such as sand adhesion, and thereby enhancing the surface quality of the casting.
b. Performance Enhancement: Through the selection of different components of the coating, special properties can be imparted to the casting tip and nozzle, such as enhanced wear resistance, corrosion resistance, and heat resistance.
c. Protective Function: The coating can form a protective film that isolates the corrosive media from the casting tip and nozzle, preventing it from being corroded and thus extending its service life.

Ceramic fiber paper and coating offer advantages and disadvantages, and the specific choice should be based on the requirements and application scenarios.
