Boron Nitride Coating
Boron nitride coating is an inert inorganic high-temperature lubricating material. It is non-sticky and does not penetrate molten metal liquid. It can completely protect the surface of refractory materials or ceramic containers in direct contact with molten aluminum, magnesium, zinc alloys, and slag, playing a role in high-temperature resistance, anti-adhesion, and oxidation resistance, thereby improving casting efficiency, reducing the defect rate, and extending the service life of the mold. In addition, boron nitride coatings can also be used in the smelting and casting of aluminum alloys to protect the metal surface, prevent oxidation and corrosion, and improve the wear resistance and fatigue resistance of aluminum alloys.

Repair agent
Ceramic fiber sealant is made from high-quality aluminosilicate fiber as the main raw material and can be used in the aluminum melting and casting industry for repairing refractory materials, sealing the interfaces of refractory materials, and kiln construction. RSH type fiber adhesive is known for its excellent anti-shrinkage and convenient construction characteristics. This type of product has selective adhesion, strong adhesion to the surface of inorganic non-metallic substrates, but shows non-sticky lubricity to technical tools such as trowels and shovels used in construction. This makes it easier for operators to smooth and hang the mud during construction. Its fine, smooth, and non-corrosive texture is also an environmentally friendly characteristic of this product.

Distribution trough
A complete trough system solution can be designed according to customer needs. This includes converter troughs, transfer ladles, casting troughs, and distribution troughs. Matching trough products, heating systems, and trough gates (slag barrier/flow control) are also provided.

Filtration
● Deep bed grid
● Alumina filter media (alumina balls, gravel)
● Filter box lining

Flow control device
Made by casting with high-quality raw materials. Used to regulate the flow rate of aluminum liquid. The product has high strength, is resistant to scouring, has a long service life, is not easy to peel, and has stable flow control.
● Plug rod
● Bottom casting tube

Slag barrier ring
The slag barrier ring effectively inhibits the formation of oxide skin at the front end of the flat billet casting, improves the surface quality and yield of the flat billet, and is particularly suitable for the production of easily oxidized alloys. More durable thin-walled slag barrier rings are made to adapt to small spaces and can be placed in deeper positions, making the slag barrier ring more widely applicable.
