3 Piece Pre-Fabricated Mould (Zircon Washed)

The main material is SiO2, it used to bind up the two ends of rail, make up a inner space to contain the liquid steel which from the portion powder reaction.

Sand molds are used in thermit welding to form a cavity around the rail ends to be joined. The mold is made of sand and other materials and is designed to hold the molten metal produced during the thermit reaction. The sand mold plays a critical role in thermit welding, and its advantages include

Provides a uniform cavity: The sand mold is designed to provide a uniform cavity around the rail ends to be joined, ensuring that the molten metal is distributed evenly.

Easy to handle: Sand molds are relatively easy to handle and can be easily formed around the rail ends to be joined, allowing for precise application and reducing the risk of spills.
