Flux for
centrifugal casting of composite roll is a kind of protective agent
of metal oxidation. As an ideal protective material in foundry
industry, it shows a certain temperature-viscosity curve, and has
many good performances such as fast melting property, film forming
property, sealing property and floating property. To meet the need
of centrifugal press casting of bimetal products, sodium borate
(“NB” for short) type glass can be added into “O” or “L” type glass
to adjust the temperature-viscosity curve. Recently, many
new products, such as “YK***7” type glass, “YY*1” type glass and
“YY*2” type glass used in rolling industry, have been in the
international level, and those products have already been exported
to some other Asian countries.
