PRODUCT DESCRIPTION
Boron Nitride Coating have two kinds of forms. One is a powder mixed with water to form a highly refractory, very robust coating for skimmers, ladles , plungers pouring basins , launders refractories, etc.,. Coating can withstand long periods of use and abrasion. Another is liquid which specially designed to used for aluminum ingot mould and prevent mould from attack by molten metal.
PRODUCT FUNCTION
In the melting of aluminum alloys,
there is a danger of iron contamination arising from the use of
unprotected furnace tools. This may have a deleterious effect on
castings and should be prevented by coating the areas of tools
coming into contact with the molten alloys by a material which is
both refractory and resistant to abrasion. Powder is suitable for
this purpose. In the production of copper-base alloys iron may also
be picked up. Although small quantities of iron do not greatly
affect the mechanical properties of aluminum alloys, they may
result in the incidence of hard inclusions in the casting.
Because of the higher temperatures involved, the life of
unprotected tools may be very short. A regular treatment of
BN-Powder protects furnace tools, increasing their life and
reducing the risk of hard inclusions in casting.
PRODUCT APPLICATION
One kilogram of BN-Powder paste is
mixed 0.5 litre of water when ready for use it has a creamy
consistency. BN-Liquid coating is mixed 1Kg of kerosene when ready
for use it. The mixture should be stirred thoroughly at
intervals.
To apply to plungers, skimmers, tongs and other furnace tools,
their cleaned working ends are thoroughly heated to between *0 and
**0℃ and plunged into the freshly-stirred BN-coating mixture. The
coating can be extended over any required area by brushing or
swabbing. The treatment may be repeated several times daily as
required.
Iron and steel ladles and shanks are given 3 or 4 coatings once or
twice daily before use. Several thin coating give better protection
than a single thick one.
It is very important that BN-Powder be thoroughly dried before
being brought into contact with liquid metal. This may be done by
placing them near to the furnace for a period and then into the
furnace flame immediately before being used.
