Name of product
|
Grain refiner
|
|
Brand
|
Desofin
|
|
Form of product
|
*0g/capsule, can be put into the
copper melt together with the sealing aluminum capsule packing
while being used.
|
|
Consumption
|
**0 grams capsule for each 1metric
ton of melted brass or melted alloy
|
|
Alloy requirements
|
â—†Suitable for all copper alloy,
including pure copper (*9.*5%) , Work best on brass
alloy.
|
|
â—†Can be used to lower the casting
temperatures and increase the castability and fluidity of the
aluminum bronze, red brass and tin bronze.
|
|
|
â—†Also proper for aluminum high
pressure casting, parts will come out bright and shiny
|
|
|
â—†Can be used on the dross
which is being removed from the melt to get the trapped metal to
flow back to the pool of liquid metal
|
|
|
â—†Also good for nickel,
silver and gold to clean and grain refine.
|
|
|
Method of use
|
â—†Products shall be free of any
moisture.
|
|
â—†Any adjustments to the aluminum or
zinc content of the melt should be made prior to adding
Desofin.
|
|
|
â—†The surface of the melt should be
reasonably free of slag.
|
|
|
â—†Desofin should be added to the melt
by immersing the capsules at least **0 cm. below the liquid metal
surface using a bell shaped plunger and the furnace should be in
low tap.
|
|
|
â—†Stir the melt uniformly after
putting Desofin into it.
|
|
|
Expected benefits
|
â—†Improved Fluidity of the metal to
be cast.
|
|
â—†Lower the casting Temperatures are
possible depending on the size of the part to be cast and the type
of mold to be used. Generally between **0 and **0 degrees C for
beryllium copper molds.
|
|
|
â—†Lower temperatures are possible if
the iron steel molds are used.
|
|
|
â—†Cracking Tendencies of the parts to
be cast are greatly reduced and most often, cracks are
eliminated.
|
|
|
â—†The occurrence of the sinks is
greatly reduced.
|
|
|
â—†Lead is more uniformly distributed
in the fine grain structure.
|
|
|
Potential savings
|
â—†Savings over the cost of purchasing
fine grained ingot.
|
|
â—†Reduction of casting
scrap.
|
|
|
â—†Reduction in finishing and rework
costs.
|
|
|
â—†Energy savings resulting from lower
casting temperatures.
|
|
|
â—†It is not necessary to refine
foundry scrap, i.e. gates, risers and turnings already grain
refined.
