Taambrapack Tube Accuracy: A 2% Of Fs At 70 A F (21.1 A C)

Taambrapack Tube
CHARACTERISTICS AND FEATURES: The oxides of copper are removed
from melts by the introduction of materials, which have a greater
affinity for oxygen than has copper. The oxides formed are of such a
nature that they separate easily from the melt. The removal of oxygen
from molten copper and its alloys increases metal fluidity and
minimizes the risk of gassy castings with low mechanical properties.
Tambrapack tubes form a range of weighed products all contained in pure
copper or brass tubes, identified with coloured stripes. The contents
of the tubes vary depending upon the application for which they are
required. The nomenclatures of the products are:

METHOD OF USING: The metal should be melted down under the
appropriate grade of TAMBRUS, SILBRAL etc. Deoxidation operation should
be carried last before pouring. The selected tubes are introduced to
the metal using a forked steel rod coated with a dressing of ALUMINITE,
plunged deep into the bottom of melt and held there to allow their
contents to become absorbed. The metal is then stirred well, skimmed
and poured.ADVANTAGES:



Tambrapack tubes are an easy method of making an accurate addition deep within the melt.Dispersion of Tambrapack tubes content is rapid and complete.Metal fluidity is improved and major causes of porosity in castings are eliminated.
MODE OF STORAGE: Keep in dry place and away from the moisture.SHELF LIFE: One year from the date of manufacture.MODE OF PACKING: 100 Nos. Card board boxes.
500Nos. in wooden case.
