These two product lines utilize the same technology in which a dry refractory aggregate
is mixed with a proprietary compound on the work site.
Penetration of liquid metal into, the mold's porous refractory aggregate
is resisted by surface tension of the metal and gas pressure in the pores.
This technology utilizes a two-component refractory system that incorporates a dry refractory aggregate
that is mixed with a proprietary acid compound onsite.
Following the path of a precursor of slag, metal seeping into the interconnected, sponge-like pores of the refractory aggregate
can lead to superheating and breach of the lining.
Sand reclamation is the physical, chemical or thermal treatment of a refractory aggregate
to allow its reuse without significantly lowering its original useful properties for the application involved.
